This work has been long in preparation—ever since in 1902-1903 Professor James Harvey Robinson, when my mind was still in the making, suggested the study of magic in medieval universities as the subject of my thesis for the master’s degree at Columbia University—and has been foreshadowed by other publications, some of which are listed under my name in the preliminary bibliography. Since this was set up in type there have also appeared: “Galen: the Man and His Times,” in The Scientific Monthly, January, 1922; “Early Christianity and Natural Science,” in The Biblical Review, July, 1922; “The Latin Pseudo-Aristotle and Medieval Occult Science,” in The Journal of English and Germanic Philology, April, 1922; and notes on Daniel of Morley and Gundissalinus in The English Historical Review. For permission to make use of these previous publications in the present work I am indebted to the editors of the periodicals just mentioned, and also to the editors of The Columbia University Studies in History, Economics, and Public Law, The American Historical Review, Classical Philology, The Monist, Nature, The Philosophical Review, and Science. The form, however, of these previous publications has often been altered in embodying them in this book, and, taken together, they constitute but a fraction of it. Book I greatly amplifies the account of magic in the Roman Empire contained in my doctoral dissertation. Over ten years ago I prepared an account of magic and science in the twelfth and thirteenth centuries based on material available in print in libraries of this country and arranged topically, but I did not publish it, as it seemed advisable to supplement it by study abroad and of the manuscript material, and to adopt an arrangement by authors. The result is Books IV and V of the present work.

My examination of manuscripts has been done especially at the British Museum, whose rich collections, perhaps because somewhat inaccessibly catalogued, have been less used by students of medieval learning than such libraries as the[Pg x] Bodleian and Bibliothèque Nationale. I have worked also, however, at both Oxford and Paris, at Munich, Florence, Bologna, and elsewhere; but it has of course been impossible to examine all the thousands of manuscripts bearing upon the subject, and the war prevented me from visiting some libraries, such as the important medieval collection of Amplonius at Erfurt. However, a fairly wide survey of the catalogues of collections of manuscripts has convinced me that I have read a representative selection. Such classified lists of medieval manuscripts as Mrs. Dorothea Singer has undertaken for the British Isles should greatly facilitate the future labors of investigators in this field.

Although working in a rather new field, I have been aided by editions of medieval writers produced by modern scholarship, and by various series, books, and articles tending, at least, in the same direction as mine. Some such publications have appeared or come to my notice too late for use or even for mention in the text: for instance, another edition of the De medicamentis of Marcellus Empiricus by M. Niedermann; the printing of the Twelve Experiments with Snakeskin of John Paulinus by J. W. S. Johnsson in Bull. d. l. société franç. d’hist. d. l. méd., XII, 257-67; the detailed studies of Sante Ferrari on Peter of Abano; and A. Franz, Die kirchlichen Benediktionen im Mittelalter, 1909, 2 vols. The breeding place of the eel (to which I allude at I, 491) is now, as a result of recent investigation by Dr. J. Schmidt, placed “about 2500 miles from the mouth of the English Channel and 500 miles north-east of the Leeward Islands” (Discovery, Oct., 1922, p. 256) instead of in the Mediterranean.

A man who once wrote in Dublin[1] complained of the difficulty of composing a learned work so far from the Bodleian and British Museum, and I have often felt the same way. When able to visit foreign collections or the largest libraries in this country, or when books have been sent for my use for a limited period, I have spent all the available time in the collection of material, which has been written up later as opportunity offered. Naturally one then finds many small and some important points which require verification or further investigation, but which must be postponed until one’s next vacation or trip abroad, by which time some of the smaller points are apt to be forgotten.[Pg xi] Of such loose threads I fear that more remain than could be desired. And I have so often caught myself in the act of misinterpretation, misplaced emphasis, and other mistakes, that I have no doubt there are other errors as well as omissions which other scholars will be able to point out and which I trust they will. Despite this prospect, I have been bold in affirming my independent opinion on any point where I have one, even if it conflicts with that of specialists or puts me in the position of criticizing my betters. Constant questioning, criticism, new points of view, and conflict of opinion are essential in the pursuit of truth.

After some hesitation I decided, because of the expense, the length of the work, and the increasing unfamiliarity of readers with Greek and Latin, as a rule not to give in the footnotes the original language of passages used in the text. I have, however, usually supplied the Latin or Greek when I have made a free translation or one with which I felt that others might not agree. But in such cases I advise critics not to reject my rendering utterly without some further examination of the context and line of thought of the author or treatise in question, since the wording of particular passages in texts and manuscripts is liable to be corrupt, and since my purpose in quoting particular passages is to illustrate the general attitude of the author or treatise. In describing manuscripts I have employed quotation marks when I knew from personal examination or otherwise that the Latin was that of the manuscript itself, and have omitted quotation marks where the Latin seemed rather to be that of the description in the catalogue. Usually I have let the faulty spelling and syntax of medieval copyists stand without comment. But as I am not an expert in palaeography and have examined a large number of manuscripts primarily for their substance, the reader should not regard my Latin quotations from them as exact transliterations or carefully considered texts. He should also remember that there is little uniformity in the manuscripts themselves. I have tried to reduce the bulk of the footnotes by the briefest forms of reference consistent with clearness—consult lists of abbreviations and of works frequently cited by author and date of publication—and by use of appendices at the close of certain chapters.

Within the limits of a preface I may not enumerate all the libraries where I have been permitted to work or which[Pg xii] have generously sent books—sometimes rare volumes—to Cleveland for my use, or all the librarians who have personally assisted my researches or courteously and carefully answered my written inquiries, or the other scholars who have aided or encouraged the preparation of this work, but I hope they may feel that their kindness has not been in vain. In library matters I have perhaps most frequently imposed upon the good nature of Mr. Frederic C. Erb of the Columbia University Library, Mr. Gordon W. Thayer, in charge of the John G. White collection in the Cleveland Public Library, and Mr. George F. Strong, librarian of Adelbert College, Western Reserve University; and I cannot forbear to mention the interest shown in my work by Dr. R. L. Poole at the Bodleian. For letters facilitating my studies abroad before the war or application for a passport immediately after the war I am indebted to the Hon. Philander C. Knox, then Secretary of State, to Frederick P. Keppel, then Assistant Secretary of War, to Drs. J. Franklin Jameson and Charles F. Thwing, and to Professors Henry E. Bourne and Henry Crew. Professors C. H. Haskins,[2] L. C. Karpinski, W. G. Leutner, W. A. Locy, D. B. Macdonald, L. J. Paetow, S. B. Platner, E. C. Richardson, James Harvey Robinson, David Eugene Smith, D’Arcy W. Thompson, A. H. Thorndike, E. L. Thorndike, T. Wingate Todd, and Hutton Webster, and Drs. Charles Singer and Se Boyar have kindly read various chapters in manuscript or proof and offered helpful suggestions. The burden of proof-reading has been generously shared with me by Professors B. P. Bourland, C. D. Lamberton, and Walter Libby, and especially by Professor Harold North Fowler who has corrected proof for practically the entire work. After receiving such expert aid and sound counsel I must assume all the deeper guilt for such faults and indiscretions as the book may display.

DESIGNATION OF MANUSCRIPTS

Individual manuscripts are usually briefly designated in the ensuing notes and appendices by a single word indicating the place or collection where the MS is found and the number or shelf-mark of the individual MS. So many of the catalogues of MSS collections which I consulted were undated and without name of author that I have decided to attempt no catalogue of them. The brief designations that I give will be sufficient for anyone who is interested in MSS. In giving Latin titles, Incipits, and the like of MSS I employ quotation marks when I know from personal examination or otherwise that the wording is that of the MS itself, and omit the marks where the Latin seems rather to be that of the description in the manuscript catalogue or other source of information. In the following List of Works Frequently Cited are included a few MSS catalogues whose authors I shall have occasion to refer to by name.

For more detailed bibliography on specific topics and for editions or manuscripts of the texts used see the bibliographies, references, and appendices to individual chapters. I also include here some works of general interest or of rather cursory character which I have not had occasion to mention elsewhere; and I usually add, for purposes of differentiation, other works in our field by an author than those works by him which are frequently cited. Of the many histories of the sciences, medicine, and magic that have appeared since the invention of printing I have included but a small selection. Almost without exception they have to be used with the greatest caution.

“Magic has existed among all peoples and at every period.”—Hegel.[3]

This book aims to treat the history of magic and experimental science and their relations to Christian thought during the first thirteen centuries of our era, with especial emphasis upon the twelfth and thirteenth centuries. No[Pg 2] adequate survey of the history of either magic or experimental science exists for this period, and considerable use of manuscript material has been necessary for the medieval period. Magic is here understood in the broadest sense of the word, as including all occult arts and sciences, superstitions, and folk-lore. I shall endeavor to justify this use of the word from the sources as I proceed. My idea is that magic and experimental science have been connected in their development; that magicians were perhaps the first to experiment; and that the history of both magic and experimental science can be better understood by studying them together. I also desire to make clearer than it has been to most scholars the Latin learning of the medieval period, whose leading personalities even are generally inaccurately known, and on perhaps no one point is illumination more needed than on that covered by our investigation. The subject of laws against magic, popular practice of magic, the witchcraft delusion and persecution lie outside of the scope of this book.[4]

At first my plan was to limit this investigation to the twelfth and thirteenth centuries, the time of greatest medieval productivity, but I became convinced that this period could be best understood by viewing it in the setting of the Greek, Latin, and early Christian writers to whom it owed so much. If the student of the Byzantine Empire needs to know old Rome, the student of the medieval church to comprehend early Christianity, the student of Romance languages to understand Latin, still more must the reader of Constantinus Africanus, Vincent of Beauvais, Guido Bonatti, and Thomas Aquinas be familiar with the Pliny, Galen, and Ptolemy, the Origen and Augustine, the Alkindi and Albumasar from whom they drew. It would indeed be difficult to draw a line anywhere between them. The ancient[Pg 3] authors are generally extant only in their medieval form; in some cases there is reason to suspect that they have undergone alteration or addition; sometimes new works were fathered upon them. In any case they have been preserved to us because the middle ages studied and cherished them, and to a great extent made them their own. I begin with the first century of our era, because Christian thought begins then, and then appeared Pliny’s Natural History which seems to me the best starting point of a survey of ancient science and magic.[5] I close with the thirteenth century, or, more strictly speaking, in the course of the fourteenth, because by then the medieval revival of learning had spent its force. Attention is centred on magic and experimental science in western Latin literature and learning, Greek and Arabic works being considered as they contributed thereto, and vernacular literature being omitted as either derived from Latin works or unlearned and unscientific.

Very probably I have tried to cover too much ground and have made serious omissions. It is probably true that for the history of thought as for the history of art the evidence and source material is more abundant than for political or economic history. But fortunately it is more reliable, since the pursuit of truth or beauty does not encourage deception and prejudice as does the pursuit of wealth or power. Also the history of thought is more unified and consistent, steadier and more regular, than the fluctuations and diversities of political history; and for this reason its general outlines can be discerned with reasonable sureness by the examination of even a limited number of examples, provided they are properly selected from a period of sufficient duration. Moreover, it seems to me that in the present stage of research into and knowledge of our subject[Pg 4] sounder conclusions and even more novel ones can be drawn by a wide comparative survey than by a minutely intensive and exhaustive study of one man or of a few years. The danger is of writing from too narrow a viewpoint, magnifying unduly the importance of some one man or theory, and failing to evaluate the facts in their full historical setting. No medieval writer whether on science or magic can be understood by himself, but must be measured in respect to his surroundings and antecedents.

Some may think it strange that I associate magic so closely with the history of thought, but the word comes from the Magi or wise men of Persia or Babylon, to whose lore and practices the name was applied by the Greeks and Romans, or possibly we may trace its etymology a little farther back to the Sumerian or Turanian word imga or unga, meaning deep or profound. The exact meaning of the word, “magic,” was a matter of much uncertainty even in classical and medieval times, as we shall see. There can be no doubt, however, that it was then applied not merely to an operative art, but also to a mass of ideas or doctrine, and that it represented a way of looking at the world. This side of magic has sometimes been lost sight of in hasty or assumed modern definitions which seem to regard magic as merely a collection of rites and feats. In the case of primitive men and savages it is possible that little thought accompanies their actions. But until these acts are based upon or related to some imaginative, purposive, and rational thinking, the doings of early man cannot be distinguished as either religious or scientific or magical. Beavers build dams, birds build nests, ants excavate, but they have no magic just as they have no science or religion. Magic implies a mental state and so may be viewed from the standpoint of the history of thought. In process of time, as the learned and educated lost faith in magic, it was degraded to the low practices and beliefs of the ignorant and vulgar. It was this use of the term that was taken up by anthropologists and by them applied to analogous doings and[Pg 5] notions of primitive men and savages. But we may go too far in regarding magic as a purely social product of tribal society: magicians may be, in Sir James Frazer’s words,[6] “the only professional class” among the lowest savages, but note that they rank as a learned profession from the start. It will be chiefly through the writings of learned men that something of their later history and of the growth of interest in experimental science will be traced in this work. Let me add that in this investigation all arts of divination, including astrology, will be reckoned as magic; I have been quite unable to separate the two either in fact or logic, as I shall illustrate repeatedly by particular cases.[7]

Magic is very old, and it will perhaps be well in this introductory chapter to present it to the reader, if not in its infancy—for its origins are much disputed and perhaps antecede all record and escape all observation—at least some centuries before its Roman and medieval days. Sir J. G. Frazer, in a passage of The Golden Bough to which we have already referred, remarks that “sorcerers are found in every savage tribe known to us; and among the lowest savages ... they are the only professional class that exists.”[8] Lenormant affirmed in his Chaldean Magic and Sorcery[9] that “all magic rests upon a system of religious belief,” but recent sociologists and anthropologists have[Pg 6] inclined to regard magic as older than a belief in gods. At any rate some of the most primitive features of historical religions seem to have originated from magic. Moreover, religious cults, rites, and priesthoods are not the only things that have been declared inferior in antiquity to magic and largely indebted to it for their origins. Combarieu in his Music and Magic[10] asserts that the incantation is universally employed in all the circumstances of primitive life and that from it, by the medium it is true of religious poetry, all modern music has developed. The magic incantation is, in short, “the oldest fact in the history of civilization.” Although the magician chants without thought of æsthetic form or an artistically appreciative audience, yet his spell contains in embryo all that later constitutes the art of music.[11] M. Paul Huvelin, after asserting with similar confidence that poetry,[12] the plastic arts,[13] medicine, mathematics, astronomy, and chemistry “have easily discernable magic sources,” states that he will demonstrate that the same is true of law.[14] Very recently, however, there has been something of a reaction against this tendency to regard the life of primitive man as made up entirely of magic and to trace back every phase of civilization to a magical origin. But R. R. Marett still sees a higher standard of value in primitive man’s magic than in his warfare and brutal exploitation of his fellows and believes that the “higher plane of experience for which mana stands is one in which spiritual enlargement is appreciated for its own sake.”[15]

Of the five classics included in the Confucian Canon, The Book of Changes (I Ching or Yi-King), regarded by[Pg 7] some as the oldest work in Chinese literature and dated back as early as 3000 B.C., in its rudimentary form appears to have been a method of divination by means of eight possible combinations in triplets of a line and a broken line. Thus, if a be a line and b a broken line, we may have aaa, bbb, aab, bba, abb, baa, aba, and bab. Possibly there is a connection with the use of knotted cords which, Chinese writers state, preceded written characters, like the method used in ancient Peru. More certain would seem the resemblance to the medieval method of divination known as geomancy, which we shall encounter later in our Latin authors. Magic and astrology might, of course, be traced all through Chinese history and literature. But, contenting ourselves with this single example of the antiquity of such arts in the civilization of the far east, let us turn to other ancient cultures which had a closer and more unmistakable influence upon the western world.

Of the ancient Egyptians Budge writes, “The belief in magic influenced their minds ... from the earliest to the latest period of their history ... in a manner which, at this stage in the history of the world, is very difficult to understand.”[16] To the ordinary historical student the evidence for this assertion does not seem quite so overwhelming as the Egyptologists would have us think. It looks thinner when we begin to spread it out over a stretch of four[Pg 8] thousand years, and it scarcely seems scientific to adduce details from medieval Arabic tales or from the late Greek fiction of the Pseudo-Callisthenes or from papyri of the Christian era concerning the magic of early Egypt. And it may be questioned whether two stories preserved in the Westcar papyrus, written many centuries afterwards, are alone “sufficient to prove that already in the Fourth Dynasty the working of magic was a recognized art among the Egyptians.”[17]

At any rate we are told that the belief in magic not only was predynastic and prehistoric, but was “older in Egypt than the belief in God.”[18] In the later religion of the Egyptians, along with more lofty and intellectual conceptions, magic was still a principal ingredient.[19] Their mythology was affected by it[20] and they not only combated demons with magical formulae but believed that they could terrify and coerce the very gods by the same method, compelling them to appear, to violate the course of nature by miracles, or to admit the human soul to an equality with themselves.[21]

Magic was as essential in the future life as here on earth among the living. Many, if not most, of the observances and objects connected with embalming and burial had a magic purpose or mode of operation; for instance, the “magic eyes placed over the opening in the side of the body through which the embalmer removed the intestines,”[22] or the mannikins and models of houses buried with the dead. In the process of embalming the wrapping of each bandage was accompanied by the utterance of magic words.[23] In “the oldest chapter of human thought extant”—the Pyramid[Pg 9] Texts written in hieroglyphic at the tombs at Sakkara of Pharaohs of the fifth and sixth dynasties (c. 2625-2475 B.C.), magic is so manifest that some have averred “that the whole body of Pyramid Texts is simply a collection of magical charms.”[24] The scenes and objects painted on the walls of the tombs, such as those of nobles in the fifth and sixth dynasties, were employed with magic intent and were meant to be realized in the future life; and with the twelfth dynasty the Egyptians began to paint on the insides of the coffins the objects that were formerly actually placed within.[25] Under the Empire the famous Book of the Dead is a collection of magic pictures, charms, and incantations for the use of the deceased in the hereafter,[26] and while it is not of the early period, we hear that “a book with words of magic power” was buried with a pharaoh of the Old Kingdom. Budge has “no doubt that the object of every religious text ever written on tomb, stele, amulet, coffin, papyrus, etc., was to bring the gods under the power of the deceased, so that he might be able to compel them to do his will.”[27] Breasted, on the other hand, thinks that the amount and complexity of this mortuary magic increased greatly in the later period under popular and priestly influence.[28]

Breasted nevertheless believes that magic had played a great part in daily life throughout the whole course of Egyptian history. He writes, “It is difficult for the modern mind to understand how completely the belief in magic penetrated the whole substance of life, dominating popular custom and constantly appearing in the simplest acts of the daily household routine, as much a matter of course as[Pg 10] sleep or the preparation of food. It constituted the very atmosphere in which the men of the early oriental world lived. Without the saving and salutary influence of such magical agencies constantly invoked, the life of an ancient household in the East was unthinkable.”[29]

Most of the main features and varieties of magic known to us at other times and places appear somewhere in the course of Egypt’s long history. For one thing we find the ascription of magic power to words and names. The power of words, says Budge, was thought to be practically unlimited, and “the Egyptians invoked their aid in the smallest as well as in the greatest events of their life.”[30] Words might be spoken, in which case they “must be uttered in a proper tone of voice by a duly qualified man,” or they might be written, in which case the material upon which they were written might be of importance.[31] In speaking of mortuary magic we have already noted the employment of pictures, models, mannikins, and other images, figures, and objects. Wax figures were also used in sorcery,[32] and amulets are found from the first, although their particular forms seem to have altered with different periods.[33] Scarabs are of course the most familiar example.

Egyptian medicine was full of magic and ritual and its therapeusis consisted mainly of “collections of incantations and weird random mixtures of roots and refuse.”[34] Already we find the recipe and the occult virtue conceptions, the elaborate polypharmacy and the accompanying hocus-pocus which we shall meet in Pliny and the middle ages. The Egyptian doctors used herbs from other countries and preferred compound medicines containing a dozen ingredients to simple medicines.[35] Already we find such magic[Pg 11] logic as that the hair of a black calf will keep one from growing gray.[36] Already the parts of animals are a favorite ingredient in medical compounds, especially those connected with the organs of generation, on which account they were presumably looked upon as life-giving, or those which were recommended mainly by their nastiness and were probably thought to expel the demons of disease by their disagreeable properties.

In ancient Egypt, however, disease seems not to have been identified with possession by demons to the extent that it was in ancient Assyria and Babylonia. While Breasted asserts that “disease was due to hostile spirits and against these only magic could avail,”[37] Budge contents himself with the more cautious statement that there is “good reason for thinking that some diseases were attributed to ... evil spirits ... entering ... human bodies ... but the texts do not afford much information”[38] on this point. Certainly the beliefs in evil spirits and in magic do not always have to go together, and magic might be employed against disease whether or not it was ascribed to a demon.

In the case of medicine as in that of religion Breasted takes the view that the amount of magic became greater in the Middle and New Kingdoms than in the Old Kingdom. This is true so far as the amount of space occupied by it in extant records is concerned. But it would be rash to assume that this marks a decline from a more rational and scientific attitude in the Old Kingdom. Yet Breasted rather gives this impression when he writes concerning the Old Kingdom that many of its recipes were useful and rational, that “medicine was already in the possession of much empirical wisdom, displaying close and accurate observation,” and that what “precluded any progress toward real science was the belief in magic, which later began to dominate all the[Pg 12] practice of the physician.”[39] Berthelot probably places the emphasis more correctly when he states that the later medical papyri “include traditional recipes, founded on an empiricism which is not always correct, mystic remedies, based upon the most bizarre analogies, and magic practices that date back to the remotest antiquity.”[40] The recent efforts of Sethe and Wilcken, of Elliot Smith, Müller, and Hooten to show that the ancient Egyptians possessed a considerable amount of medical knowledge and of surgical and dental skill, have been held by Todd to rest on slight and dubious evidence. Indeed, some of this evidence seems rather to suggest the ritualistic practices still employed by uncivilized African tribes. Certainly the evidence for any real scientific development in ancient Egypt has been very meager compared with the abundant indications of the prevalence of magic.[41]

Early Egypt was the home of many arts and industries, but not in so advanced a stage as has sometimes been suggested. Blown glass, for example, was unknown until late Greek and Roman times, and the supposed glass-blowers depicted on the early monuments are really smiths engaged in stirring their fires by blowing through reeds tipped with clay.[42] On the other hand, Professor Breasted informs me that there is no basis for Berthelot’s statement that “every sort of chemical process as well as medical treatment was executed with an accompaniment of religious formulae, of prayers and incantations, regarded as essential to the success of operations as well as the cure of maladies.”[43]

Alchemy perhaps originated on the one hand from the practices of Egyptian goldsmiths and workers in metals, who experimented with alloys,[44] and on the other hand from[Pg 13] the theories of the Greek philosophers concerning world-grounds, first matter, and the elements.[45] The words, alchemy and chemistry, are derived ultimately from the name of Egypt itself, Kamt or Qemt, meaning literally black, and applied to the Nile mud. The word was also applied to the black powder produced by quicksilver in Egyptian metallurgical processes. This powder, Budge says, was supposed to be the ground of all metals and to possess marvelous virtue, “and was mystically identified with the body which Osiris possessed in the underworld, and both were thought to be sources of life and power.”[46] The analogy to the sacrament of the mass and the marvelous powers ascribed to the host by medieval preachers like Stephen of Bourbon scarcely needs remark. The later writers on alchemy in Greek appear to have borrowed signs and phraseology from the Egyptian priests, and are fond of speaking of their art as the monopoly of Egyptian kings and priests who carved its secrets on ancient steles and obelisks. In a treatise dating from the twelfth dynasty a scribe recommends to his son a work entitled Chemi, but there is no proof that it was concerned with chemistry or alchemy.[47] The papyri containing treatises of alchemy are of the third century of the Christian era.

Evidences of divination in general and of astrology in particular do not appear as early in Egyptian records as examples of other varieties of magic. Yet the early date at which Egypt had a calendar suggests astronomical interest, and even those who deny that seven planets were distinguished in the Tigris-Euphrates Valley until the last millennium before Christ, admit that they were known in Egypt as far back as the Old Kingdom, although they deny the existence of a science of astronomy or an art of astrology then.[48] A dream of Thotmes IV is preserved from 1450 B.C. or thereabouts, and the incantations employed by magicians[Pg 14] in order to procure divining dreams for their customers attest the close connection of divination and magic.[49] Belief in lucky and unlucky days is shown in a papyrus calendar of about 1300 B.C.,[50] and we shall see later that “Egyptian Days” continued to be a favorite superstition of the middle ages. Tables of the risings of stars which may have an astrological significance have been found in graves, and there were gods for every month, every day of the month, and every hour of the day.[51] Such numbers as seven and twelve are frequently emphasized in the tombs and elsewhere, and if the vaulted ceiling in the tenth chamber of the tomb of Sethos is really of his time, we seem to find the signs of the zodiac under the nineteenth dynasty. If Boll is correct in suggesting that the zodiac originated in the transfer of animal gods to the sky,[52] no fitter place than Egypt could be found for the transfer. But there have not yet been discovered in Egypt lists of omens and appearances of constellations on days of disaster such as are found in the literature of the Tigris-Euphrates valley and in the Roman historians. Budge speaks of the seven Hathor goddesses who predict the death that the infant must some time die, and affirms that “the Egyptians believed that a man’s fate ... was decided before he was born, and that he had no power to alter it.”[53] But I cannot agree that “we have good reason for assigning the birthplace of the horoscope to Egypt,”[54] since the evidence seems to be limited to the almost medieval Pseudo-Callisthenes and a Greek horoscope in the British Museum to which is attached the letter of an astrologer urging his pupil to study the ancient Egyptians carefully. The later Greek and Latin tradition that astrology was the invention of the divine men of Egypt and Babylon probably has a basis of fact, but more contemporary evidence is needed if Egypt is to contest the claim of Babylon to precedence in that art.

[Pg 15]

In the written remains of Babylonian and Assyrian civilization[55] the magic cuneiform tablets play a large part and give us the impression that fear of demons was a leading feature of Assyrian and Babylonian religion and that daily thought and life were constantly affected by magic. The bulk of the religious and magical texts are preserved in the library of Assurbanipal, king of Assyria from 668 to 626 B.C. But he collected his library from the ancient temple cities, the scribes tell us that they are copying very ancient texts, and the Sumerian language is still largely employed.[56] Eridu, one of the main centers of early Sumerian culture, “was an immemorial home of ancient wisdom, that is to say, magic.”[57] It is, however, difficult in the library of Assurbanipal to distinguish what is Babylonian from what is Assyrian or what is Sumerian from what is Semitic. Thus we are told that “with the exception of some very ancient texts, the Sumerian literature, consisting largely of religious material such as hymns and incantations, shows a number of Semitic loanwords and grammatical Semitisms, and in many cases, although not always, is quite patently a translation of Semitic ideas by Semitic priests into the formal religious Sumerian language.”[58]

The chief point in dispute, over which great controversy has taken place recently among German scholars, is as to the antiquity of both astronomical knowledge and astrological doctrine, including astral theology, among the dwellers in the Tigris-Euphrates region. Briefly, such writers as Winckler, Stücken, and Jeremias held that the religion of the early Babylonians was largely based on astrology and that all their thought was permeated by it, and that they had probably by an early date made astronomical observations and acquired astronomical knowledge which was lost[Pg 16] in the decline of their culture. Opposing this view, such scholars as Kugler, Bezold, Boll, and Schiaparelli have shown the lack of certain evidence for either any considerable astronomical knowledge or astrological theory in the Tigris-Euphrates Valley until the late appearance of the Chaldeans. It is even denied that the seven planets were distinguished in the early period, much less the signs of the zodiac or the planetary week,[59] which last, together with any real advance in astronomy, is reserved for the Hellenistic period.

Yet the prominence of the number seven in myth, religion, and magic is indisputable in the third millennium before our era. For instance, in the old Babylonian epic of creation there are seven winds, seven spirits of storms, seven evil diseases, seven divisions of the underworld closed by seven doors, seven zones of the upper world and sky, and so on. We are told, however, that the staged towers of Babylonia, which are said to have symbolized for millenniums the sacred Hebdomad, did not always have seven stages.[60] But the number seven was undoubtedly of frequent occurrence, of a sacred and mystic character, and virtue and perfection were ascribed to it. And no one has succeeded in giving any satisfactory explanation for this other than the rule of the seven planets over our world. This also applies to the sanctity of the number seven in the Old Testament[61] and the emphasis upon it in Hesiod, the Odyssey, and other early Greek sources.[62]

[Pg 17]

However that may be, the tendency prevailing at present is to regard astrology as a relatively late development introduced by the Semitic Chaldeans. Lenormant held that writing and magic were a Turanian or Sumerian (Accadian) contribution to Babylonian civilization, but that astronomy and astrology were Semitic innovations. Jastrow thinks that there was slight difference between the religion of Assyria and that of Babylonia, and that astral theology played a great part in both; but he grants that the older incantation texts are less influenced by this astral theology. L. W. King says, “Magic and divination bulk largely in the texts recovered, and in their case there is nothing to suggest an underlying astrological element.”[63]

Whatever its date and origin, the magic literature may be classified in three main groups. There are the astrological texts in which the stars are looked upon as gods and predictions are made especially for the king.[64] Then there are the tablets connected with other methods of foretelling the future, especially liver divination, although interpretation of dreams, augury, and divination by mixing oil and water were also practiced.[65] Fossey has further noted the close connection of operative magic with divination among the Assyrians, and calls divination “the indispensable auxiliary of magic.” Many feats of magic imply a precedent knowledge of the future or begin by consultation of a diviner, or a favorable day and hour should be chosen for the magic rite.[66]

Third, there are the collections of incantations, not however those employed by the sorcerers, which were pre[Pg 18]sumably illicit and hence not publicly preserved—in an incantation which we shall soon quote sorcery is called evil and is said to employ “impure things”—but rather defensive measures against them and exorcisms of evil demons.[67] But doubtless this counter magic reflects the original procedure to a great extent. Inasmuch as diseases generally were regarded as due to demons, who had to be exorcized by incantations, medicine was simply a branch of magic. Evil spirits were also held responsible for disturbances in nature, and frequent incantations were thought necessary to keep them from upsetting the natural order entirely.[68] The various incantations are arranged in series of tablets: the Maklu or burning, Ti’i or headaches, Asakki marsûti or fever, Labartu or hag-demon, and Nis kati or raising of the hand. Besides these tablets there are numerous ceremonial and medical texts which contain magical practice.[69] Also hymns of praise and religious epics which at first sight one would not classify as incantations seem to have had their magical uses, and Farnell suggests that “a magic origin for the practice of theological exegesis may be obscurely traced.”[70] Good spirits are represented as employing magic and exorcisms against the demons.[71] As a last resort when good spirits as well as human magic had failed to check the demons, the aid might be requisitioned of the god Ea, regarded as the repository of all science and who “alone was possessed of the magic secrets by means of which they could be conquered and repulsed.”[72]

The incantations themselves show that other factors than the power of words entered into the magic, as may be illustrated by quoting one of them.

It is evident from this incantation that use was made of magic images and knots, and of the properties of trees and herbs. Magic images were made of clay, wax, tallow, and other substances and were employed in various ways. Thus directions are given for making a tallow image of an enemy of the king and binding its face with a cord in order to deprive the person whom it represents of speech and willpower.[74] Images were also constructed in order that disease demons might be magically transferred into them,[75] and sometimes the images are slain and buried.[76] In the above incantation the magic knot was employed only by the sorceress, but Fossey states that knots were also used as[Pg 20] counter-charms against the demons.[77] In the above incantation the names of herbs were left untranslated and it is not possible to say much concerning the pharmacy of the Assyrians and Babylonians because of our lack of a lexicon for their botanical and mineralogical terminology.[78] However, from what scholars have been able to translate it appears that common rather than rare and outlandish substances were the ones most employed. Wine and oil, salt and dates, and onions and saliva are the sort of things used. There is also evidence of the employment of a magic wand.[79] Gems and animal substances were used as well as herbs; all sorts of philters were concocted; and varied rites and ceremonies were employed such as ablutions and fumigations. In the account of the ark of the Babylonian Noah we are told of the magic significance of its various parts; thus the mast and cabin ceiling were made of cedar, a wood that counteracts sorceries.[80]

One remarkable corollary of the so-called Italian Renaissance or Humanistic movement at the close of the middle ages with its too exclusive glorification of ancient Greece and Rome has been the strange notion that the ancient Hellenes were unusually free from magic compared with other periods and peoples. It would have been too much to claim any such immunity for the primitive Romans, whose entire religion was originally little else than magic and whose daily life, public and private, was hedged in by superstitious observances and fears. But they, too, were supposed to have risen later under the influence of Hellenic culture to a more enlightened stage,[81] only to relapse again into magic in the declining empire and middle ages under oriental influence. Incidentally let me add that this notion that in the past orientals were more superstitious and fond of[Pg 21] marvels than westerners in the same stage of civilization and that the orient must needs be the source of every superstitious cult and romantic tale is a glib assumption which I do not intend to make and which our subsequent investigation will scarcely substantiate. But to return to the supposed immunity of the Hellenes from magic; so far has this hypothesis been carried that textual critics have repeatedly rejected passages as later interpolations or even called entire treatises spurious for no other reason than that they seemed to them too superstitious for a reputable classical author. Even so specialized and recent a student of ancient astrology, superstition, and religion as Cumont still clings to this dubious generalization and affirms that “the limpid Hellenic genius always turned away from the misty speculations of magic.”[82] But, as I suggested some sixteen years since, “the fantasticalness of medieval science was due to ‘the clear light of Hellas’ as well as to the gloom of the ‘dark ages.’”[83]

It is not difficult to call to mind evidence of the presence of magic in Hellenic religion, literature, and history. One has only to think of the many marvelous metamorphoses in Greek mythology and of its countless other absurdities; of the witches, Circe and Medea, and the necromancy of Odysseus; or the priest-magician of Apollo in the Iliad who could stop the plague, if he wished; of the lucky and unlucky days and other agricultural magic in Hesiod.[84] Then there were the Spartans, whose so-called constitution and method of education, much admired by the Greek philosophers, were largely a retention of the life of the primitive tribe with its ritual and taboos. Or we remember Herodotus and his childish delight in ambiguous oracles or his tale of seceders from Gela brought back by Telines single-handed because he “was possessed of certain mysterious visible symbols of the powers beneath the earth which were deemed to be of[Pg 22] wonder-working power.”[85] We recall Xenophon’s punctilious records of sacrifices, divinations, sneezes, and dreams; Nicias, as afraid of eclipses as if he had been a Spartan; and the matter-of-fact mentions of charms, philters, and incantations in even such enlightened writers as Euripides and Plato. Among the titles of ancient Greek comedies magic is represented by the Goetes of Aristophanes, the Mandragorizomene of Alexis, the Pharmacomantis of Anaxandrides, the Circe of Anaxilas, and the Thettale of Menander.[86] When we candidly estimate the significance of such evidence as this, we realize that the Hellenes were not much less inclined to magic than other peoples and periods, and that we need not wait for Theocritus and the Greek romances or for the magical papyri for proof of the existence of magic in ancient Greek civilization.[87]

If astrology and some other occult sciences do not appear in a developed form until the Hellenistic period, it is not because the earlier period was more enlightened, but because it was less learned. And the magic which Osthanes is said to have introduced to the Greek world about the time of the Persian wars was not so much an innovation as an improvement upon their coarse and ancient rites of Goetia.[88]

This magic element which existed from the start in Greek culture is now being traced out by students of anthropology and early religion as well as of the classics. Miss Jane E. Harrison, in Themis, a study of the social origins of Greek religion, suggests a magical explanation for many a myth and festival, and even for the Olympic games and Greek drama.[89] The last point has been developed in more[Pg 23] detail by F. M. Cornford’s Origin of Attic Comedy, where much magic is detected masquerading in the comedies of Aristophanes.[90] And Mr. A. B. Cook sees the magician in Zeus, who transforms himself to pursue his amours, and contends that “the real prototype of the heavenly weather-king was the earthly” magician or rain-maker, that the pre-Homeric “fixed epithets” of Zeus retained in the Homeric poems “are simply redolent of the magician,” and that the cult of Zeus Lykaios was connected with the belief in werwolves.[91] In still more recent publications Dr. Rendel Harris[92] has connected Greek gods in their origins with the woodpecker and mistletoe, associated the cult of Apollo with the medicinal virtues of mice and snakes, and in other ways emphasized the importance in early Greek religion and culture of the magic properties of animals and herbs.

These writers have probably pressed their point too far, but at least their work serves as a reaction against the old attitude of intellectual idolatry of the classics. Their views may be offset by those of Mr. Farnell, who states that “while the knowledge of early Babylonian magic is beginning to be considerable, we cannot say that we know anything definite concerning the practices in this department of the Hellenic and adjacent peoples in the early period with which we are dealing.” And again, “But while Babylonian magic proclaims itself loudly in the great religious literature and highest temple ritual, Greek magic is barely mentioned in the older literature of Greece, plays no part at all in the hymns, and can only with difficulty be discovered as latent in the higher ritual. Again, Babylonian[Pg 24] magic is essentially demoniac; but we have no evidence that the pre-Homeric Greek was demon-ridden, or that demonology and exorcism were leading factors in his consciousness and practice.” Even Mr. Farnell admits, however, that “the earliest Hellene, as the later, was fully sensitive to the magico-divine efficacy of names.”[93] Now to believe in the power of names before one believes in the existence of demons is the best possible evidence of the antiquity of magic in a society, since it indicates that the speaker has confidence in the operative power of his own words without any spiritual or divine assistance.

Moreover, in one sense the advocates of Greek magic have not gone far enough. They hold that magic lies back of the comedies of Aristophanes; what they might contend is that it was also contemporary with them.[94] They hold that classical Greek religion had its origins in magic; what they might argue is that Greek philosophy never freed itself from magic. “That Empedocles believed himself capable of magical powers is,” says Zeller, “proved by his own writings.” He himself “declares that he possesses the power to heal old age and sickness, to raise and calm the winds, to summon rain and drought, and to recall the dead to life.”[95] If the pre-Homeric fixed epithets of Zeus are redolent of magic, Plato’s Timaeus is equally redolent of occult science and astrology; and if we see the weather-making magician in the Olympian Zeus of Phidias, we cannot explain away the vagaries of the Timaeus as flights of poetic imagination or try to make out Aristotle a modern scientist by mutilating the text of the History of Animals.

[Pg 25]

Toward magic so-called Plato’s attitude in his Laws is cautious. He maintains that medical men and prophets and diviners can alone understand the nature of poisons (or spells) which work naturally, and of such things as incantations, magic knots, and wax images; and that since other men have no certain knowledge of such matters, they ought not to fear but to despise them. He admits nevertheless that there is no use in trying to convince most men of this and that it is necessary to legislate against sorcery.[96] Yet his own view of nature seems impregnated, if not actually with doctrines borrowed from the Magi of the east, at least with notions cognate to those of magic rather than of modern science and with doctrines favorable to astrology. He humanized material objects and confused material and spiritual characteristics. He also, like authors of whom we shall treat later, attempted to give a natural or rational explanation for magic, accounting, for example, for liver divination on the ground that the liver was a sort of mirror on which the thoughts of the mind fell and in which the images of the soul were reflected; but that they ceased after death.[97] He spoke of harmonious love between the elements as the source of health and plenty for vegetation, beasts, and men, and their “wanton love” as the cause of pestilence and disease. To understand both varieties of love “in relation to the revolutions of the heavenly bodies and the seasons of the year is termed astronomy,”[98] or, as we should say, astrology, whose fundamental law is the control of inferior creation by the motion of the stars. Plato spoke of the stars as “divine and eternal animals, ever abiding,”[99] an expression which we shall hear reiterated in the middle ages. “The lower gods,” whom he largely identified with the heavenly bodies, form men, who, if they live good lives, return after death each to a happy existence in his proper star.[100] Such a doctrine is not identical with that of nativities[Pg 26] and the horoscope, but like it exalts the importance of the stars and suggests their control of human life. And when at the close of his Republic Plato speaks of the harmony or music of the spheres of the seven planets and the eighth sphere of the fixed stars, and of “the spindle of Necessity on which all the revolutions turn,” he suggests that when once the human soul has entered upon this life, its destiny is henceforth subject to the courses of the stars. When in the Timaeus he says, “There is no difficulty in seeing that the perfect number of time fulfills the perfect year when all the eight revolutions ... are accomplished together and attain their completion at the same time,”[101] he seems to suggest the astrological doctrine of the magnus annus, that history begins to repeat itself in every detail when the heavenly bodies have all regained their original positions.

For Aristotle, too, the stars were “beings of superhuman intelligence, incorporate deities. They appeared to him as the purer forms, those more like the deity, and from them a purposive rational influence upon the lower life of the earth seemed to proceed,—a thought which became the root of medieval astrology.”[102] Moreover, “his theory of the subordinate gods of the spheres of the planets ... provided for a later demonology.”[103]

Aside from bits of physiognomy and of Pythagorean superstition, or mysticism, Aristotle’s History of Animals contains much on the influence of the stars on animal life, the medicines employed by animals, and their friendships and enmities, and other folk-lore and pseudo-science.[104] But[Pg 27] the oldest extant manuscript of that work dates only from the twelfth or thirteenth century and lacks the tenth book. Editors of the text have also rejected books seven and nine, the latter part of book eight, and have questioned various other passages. However, these expurgations save the face of Aristotle rather than of Hellenic science or philosophy generally, as the spurious seventh book is held to be drawn largely from Hippocratic writings and the ninth from Theophrastus.[105]

There is another point to be kept in mind in any comparison of Egypt and Babylon or Assyria with Greece in the matter of magic. Our evidence proving the great part played by magic in the ancient oriental civilizations comes directly from them to us without intervening tampering or alteration except in the case of the early periods. But classical literature and philosophy come to us as edited by Alexandrian librarians[106] and philologers, as censored and selected by Christian and Byzantine readers, as copied or translated by medieval monks and Italian humanists. And the question is not merely, what have they added? but also, what have they altered? what have they rejected? Instead of questioning superstitious passages in extant works on the ground that they are later interpolations, it would very likely be more to the point to insert a goodly number on the ground that they have been omitted as pagan or idolatrous superstitions.

Suppose we turn to those writings which have been unearthed just as they were in ancient Greek; to the papyri, the lead tablets, the so-called Gnostic gems. How does the proportion of magic in these compare with that in the indirectly transmitted literary remains? If it is objected that the magic papyri[107] are mainly of late date and that[Pg 28] they are found in Egypt, it may be replied that they are as old as or older than any other manuscripts we have of classical literature and that its chief storehouse, too, was in Egypt at Alexandria. As for the magical curses written on lead tablets,[108] they date from the fourth century before our era to the sixth after, and fourteen come from Athens and sixteen from Cnidus as against one from Alexandria and eleven from Carthage. And although some display extreme illiteracy, others are written by persons of rank and education. And what a wealth of astrological manuscripts in the Greek language has been unearthed in European libraries by the editors of the Catalogus Codicum Graecorum Astrologorum![109] And occasionally archaeologists report the discovery of magical apparatus[110] or of representations of magic in works of art.

In thus contending that Hellenic culture was not free from magic and that even the philosophy and science of the ancient Greeks show traces of superstition, I would not, however, obscure the fact that of extant literary remains the Greek are the first to present us with any very considerable body either of systematic rational speculation or of classified collection of observed facts concerning nature. Despite the rapid progress in recent years in knowledge of prehistoric man and Egyptian and Babylonian civilization, the Hellenic[Pg 29] title to the primacy in philosophy and science has hardly been called in question, and no earlier works have been discovered that can compare in medicine with those ascribed to Hippocrates, in biology with those of Aristotle and Theophrastus, or in mathematics and physics with those of Euclid and Archimedes. Undoubtedly such men and writings had their predecessors, probably they owed something to ancient oriental civilization, but, taking them as we have them, they seem to be marked by great original power. Whatever may lie concealed beneath the surface of the past, or whatever signs or hints of scientific investigation and knowledge we may think we can detect and read between the lines, as it were, in other phases of older civilizations, in these works solid beginnings of experimental and mathematical science stand unmistakably forth.

“An extraordinarily large proportion of the subject matter of the writings of Archimedes,” says Heath, “represents entirely new discoveries of his own. Though his range of subjects was almost encyclopædic, embracing geometry (plane and solid), arithmetic, mechanics, hydrostatics and astronomy, he was no compiler, no writer of text-books.... His objective is always some new thing, some definite addition to the sum of knowledge, and his complete originality cannot fail to strike anyone who reads his works intelligently, without any corroborative evidence such as is found in the introductory letters prefixed to most of them.... In some of his subjects Archimedes had no forerunners, e. g., in hydrostatics, where he invented the whole science, and (so far as mathematical demonstration was concerned) in his mechanical investigations.”[111] Aristotle’s History of Animals is still highly esteemed by historians of biology[112] and often evidences “a large amount of personal[Pg 30] observations,”[113] “great accuracy,” and “minute inquiry,” as in his account of the vascular system[114] or observations on the embryology of the chick.[115] “Most wonderful of all, perhaps, are those portions of his book in which he speaks of fishes, their diversities, their structure, their wanderings, and their food. Here we may read of fishes that have only recently been rediscovered, of structures only lately reinvestigated, of habits only of late made known.”[116] But of the achievements of Hellenic philosophy and Hellenistic science the reader may be safely assumed already to have some notion.

But in closing this brief preliminary sketch of the period before our investigation proper begins, I would take exception to the tendency, prevalent especially among German scholars, to center in and confine to Aristotle and the Hellenistic age almost all progress in natural science made before modern times. The contributions of the Egyptians and Babylonians are reduced to a minimum on the one hand, while on the other the scientific writings of the Roman[Pg 31] Empire, which are extant in far greater abundance than those of the Hellenistic period, are regarded as inferior imitations of great authors whose works are not extant; Posidonius, for example, to whom it has been the fashion of the writers of German dissertations to attribute this, that, and every theory in later writers. But it is contrary to the law of gradual and painful acquisition of scientific knowledge and improvement of scientific method that one period of a few centuries should thus have discovered everything. We have disputed the similar notion of a golden age of early Egyptian science from which the Middle and New Kingdoms declined, and have not held that either the Egyptians or Babylonians had made great advances in science before the Greeks. But that is not saying that they had not made some advance. As Professor Karpinski has recently written:

“To deny to Babylon, to Egypt, and to India, their part in the development of science and scientific thinking is to defy the testimony of the ancients, supported by the discoveries of the modern authorities. The efforts which have been made to ascribe to Greek influence the science of Egypt, of later Babylon, of India, and that of the Arabs do not add to the glory that was Greece. How could the Babylonians of the golden age of Greece or the Hindus, a little later, have taken over the developments of Greek astronomy? This would only have been possible if they had arrived at a state of development in astronomy which would have enabled them properly to estimate and appreciate the work which was to be absorbed.... The admission that the Greek astronomy immediately affected the astronomical theories of India carries with it the implication that this science had attained somewhat the same level in India as in Greece. Without serious questioning we may assume that a fundamental part of the science of Babylon and Egypt and India, developed during the times which we think of as Greek, was indigenous science.”[117]

[Pg 32]

Nor am I ready to admit that the great scientists of the early Roman Empire merely copied from, or were distinctly inferior to, their Hellenistic predecessors. Aristarchus may have held the heliocentric theory[118] but Ptolemy must have been an abler scientist and have supported his incorrect hypothesis with more accurate measurements and calculations or the ancients would have adopted the sounder view. And if Herophilus had really demonstrated the circulation of the blood, so keen an intelligence as Galen’s would not have cast his discovery aside. And if Ptolemy copied Hipparchus, are we to imagine that Hipparchus copied from no one? But of the incessant tradition from authority to authority and yet of the gradual accumulation of new matter from personal observation and experience our ensuing survey of thirteen centuries of thought and writing will afford more detailed illustration.

The following books deal expressly with the magic of Assyria and Babylonia:

Much concerning magic will also be found in works on Babylonian and Assyrian religion.

On the astronomy and astrology of the Babylonians one may consult:

BOOK I. THE ROMAN EMPIRE

A trio of great names, Pliny, Galen, and Ptolemy, stand out above all others in the history of science under the Roman Empire. In the use or criticism which they make of earlier writers and investigators they are also our chief sources for the science of the preceding Hellenistic period. By their voluminousness, their generous scope in ground covered, and their broad, liberal, personal outlooks, they have painted, in colors for the most part imperishable, extensive canvasses of the scientific spirit and acquisitions of their own time. Pliny pursued politics and literature as well as natural science; Ptolemy was at once mathematician, astronomer, physicist, and geographer; Galen knew philosophy as well as medicine. The two latter men, moreover, made original contributions of their own of the very first order to scientific knowledge and method. It is characteristic of the homogeneous and widespread culture of the Roman Empire that these three representatives of different, although overlapping, fields of science were natives of the three continents that enclose the Mediterranean Sea. Pliny was born at Como where Italy verges on transalpine lands; Ptolemy, born somewhere in Egypt, did his work at Alexandria; Galen came from Pergamum in Asia Minor. Finally, these men were, after Aristotle, the three ancient scientists who directly or indirectly most powerfully influenced the middle ages. Thus they illuminate past, present, and future.

We shall therefore open the present section of our investigation by considering in turn chronologically, Pliny, Ptolemy, and Galen, coupling, however, with our consideration of Ptolemy the work of Seneca on Natural Questions[Pg 40] which shows the same combination of natural science and natural divination. Next we shall consider some representatives of ancient applied science and its relations to magic, and the more miscellaneous writings of Plutarch, Apuleius, and Philostratus’s Life of Apollonius of Tyana. From the hospitable attitude toward magic and occult science displayed by these last writers we shall then turn back again to consider some examples of literary and philosophical attacks upon superstition, before proceeding lastly to spurious mystic writings of the Roman Empire, Neo-Platonism and its relations to astrology and theurgy, and the works of Aelian, Solinus, and Horapollo.

—Closing words of the Natural History.[119]

We should have to search long before finding a better starting-point for the consideration of the union of magic with the science of the Roman Empire, and of the way in which that union influenced the middle ages, than Pliny’s Natural History.[120] The foregoing sentence, with which years ago I opened a chapter on the Natural History of Pliny the Elder in my briefer preliminary study of magic in the intellectual history of the Roman Empire, seems as true as ever; and although I there considered his confusion of magic and science at some length, I do not see how I can make the present work well-rounded and complete without including in it a yet more detailed analysis of the contents of Pliny’s book.

Pliny’s Natural History, which appeared about 77 A.D. and is dedicated to the Emperor Titus, is perhaps the most[Pg 43] important single source extant for the history of ancient civilization. Its thirty-seven books, written in a very compact style, constitute a vast collection of the most miscellaneous information. Whether one is investigating ancient painting, sculpture, and other fine arts; or the geography of the Roman Empire; or Roman triumphs, gladiatorial contests, and theatrical exhibitions; or the industrial processes of antiquity; or Mediterranean trade; or Italian agriculture; or mining in ancient Spain; or the history of Roman coinage; or the fluctuation of prices in antiquity; or the Roman attitude towards usury; or the pagan attitude towards immortality; or the nature of ancient beverages; or the religious usages of the ancient Romans; or any of a number of other topics; one will find something concerning all of them in Pliny. He is apt both to depict such conditions in his own time and to trace them back to their origins. Furthermore he repeats many detailed incidents of interest to the political or narrative historian of Rome as well as to the student of the economic, social, artistic, and religious life of antiquity. Probably there is no place where an isolated point is more likely to be run down by the investigator, and it is regrettable that exhaustive analytical indices of the work are not available. We may add that, although the work is supposedly a collection of facts, Pliny contrives to introduce many moral reflections and sharp comments on the luxury, vice, and unintellectual character of his times, suggesting Juvenal’s picture of degenerate Roman society and his own lofty moral standards.

Indeed, Pliny’s title, Naturalis Historia, or at least the common English translation of it, “Natural History,” has been criticized as too limited in scope, and the work has been described as “rather a vast encyclopedia of ancient knowledge and belief upon almost every known subject.”[121] Pliny himself mentions in his preface the Greek word “encyclopedia” as indicative of his scope. Nevertheless, his work is primarily an account of nature rather than of civili[Pg 44]zation, and much of its information concerning such matters as the arts and business is incidental. Most of its books bear such titles as Aquatic Animals, Exotic Trees, Medicines from Forest Trees, The Natures of Metals. After an introductory book containing the preface and a table of contents and lists of authorities for each of the subsequent books, the second book treats of the universe, heavenly bodies, meteorology, and the chief changes, such as earthquakes and tides, in the land and water forming the earth’s surface. After four books devoted to geography, the seventh deals with man and human inventions. Four more follow on terrestrial and aquatic animals, birds, and insects. Sixteen more are concerned with plants, trees, vines, and other vegetation, and the medicinal simples derived from them. Five books discuss the medicinal simples derived from animals, including the human body; and the last five books treat of metals and minerals and the arts in which they are employed. It is thus evident that in the main Pliny is concerned with natural science, and that, if his work is a mine of miscellaneous historical information, it should even more prove a rich treasure-house—“quoniam, ut ait Domitius Piso, thesauros oportet esse non libros”[122]—for an investigation concerned as intimately as is ours with the history of science.

The Natural History is a great storehouse of misinformation as well as of information, for Pliny’s credulity and lack of discrimination harvested the tares of legend and magic along with the wheat of historical fact and ancient science in his voluminous granary. This may put other historical investigators upon their guard in accepting its statements, but only increases its value for our purpose. Perhaps it is even more valuable as a collection of ancient errors than it is as a repository of ancient science. It touches upon many of the varieties, and illustrates most of the characteristics, of magic. Moreover, Pliny often mentions the Magi or magicians and discusses “magic” expressly at some[Pg 45] length in the opening chapters of his thirtieth book—one of the most important passages on the theme in any ancient writer.

Pliny the Elder, as we learn from his own statements in the Natural History and from one or two letters concerning him written by his nephew, Pliny the Younger, whom he adopted, went through the usual military, forensic, and official career of the Roman of good family, and spent his life largely in the service of the emperors. He visited various Mediterranean lands, such as Spain, Africa, Greece, and Egypt, and fought in Germany. He was in charge of the Roman fleet on the west coast of Italy when he met his death at the age of fifty-six by suffocation as he was trying to rescue others from the fumes and vapors from the eruption of Mount Vesuvius.

Of Pliny’s writings the Natural History is alone extant, but other titles have been preserved which serve to show his great literary industry and the extent of his interests. He wrote on the use of the javelin by cavalry, a life of his friend Pomponius, an account in twenty books of all the wars waged by the Romans in Germany, a rather long work on oratory called The Student, a grammatical or philological work in eight books entitled De dubio sermone, and a continuation of the History of Aufidius Bassus in thirty-one books. Yet in the dedication of the Natural History to the emperor Titus he states that his days were taken up with official business and only his nights were free for literary labor. This statement is supported by a letter of his nephew telling how he used to study by candle-light both late at night and before daybreak. Pliny the Younger narrates several incidents to illustrate how jealous and economical of every spare moment his uncle was. He would dictate or have books read to him while lying down or in the bath, and on journeys a secretary was always by his side with books and tablets. If the weather was very cold, the amanuensis wore gloves so that his hands might not become too numb to write. Pliny always took notes on what he read, and at[Pg 46] his death left his nephew one hundred and sixty notebooks written in a small hand on both sides.

Such were the conditions under which, and the methods by which, Pliny compiled his encyclopedia on nature. No single writer either Greek or Latin, he tells us, had ever before attempted so extensive a task. He adds that he treats of some twenty thousand topics gleaned from the perusal of about two thousand volumes by one hundred authors.[123] Judging from his bibliographies and citations, however, he would seem to have utilized more than one hundred authors. But possibly he had not read all the writers mentioned in his bibliographies. He affirms that previous students have had access to but few of the volumes which he has used, and that he adds many things unknown to his ancient authorities and recently discovered. Occasionally he shows an acquaintance with beliefs and practices of the Gauls and Druids. Thus his work assumes to be something more than a compilation from other books. He says, however, that no doubt he has omitted much, since he is only human and has had many other demands upon his time. He admits that his subject is dry (sterilis materia) and does not lend itself to literary exhibitions, nor include matters stimulating to write about and pleasant to read about, like speeches and marvelous occurrences and varied incidents. Nor does it permit purity and elegance of diction, since one must at times employ the terminology of rustics, foreigners, and even barbarians. Furthermore, “it is an arduous task to give novelty to what is ancient, authority to what is new, interest to what is obsolete, light to what is obscure, charm to what is loathsome”—as many of his medicinal simples undoubtedly are—“credit to what is dubious.”

It is a great comfort to Pliny, however, in his immense task, when many laugh at him as wasting his time over worthless trifles, to reflect that he is being spurned along with Nature.[124] In another passage[125] he contrasts the blood[Pg 47] and slaughter of military history with the benefits bestowed upon mankind by astronomers. In a third passage[126] he looks back regretfully at the widespread interest in science among the Greeks, although those were times of political disunion and strife and although communication between different lands was interrupted by piracy as well as war, whereas now, with the whole empire at peace, not only is no new scientific inquiry undertaken, but men do not even thoroughly study the works of the ancients, and are intent on the acquisition of lucre rather than learning. These and other passages which might be cited attest Pliny’s devotion to science.

In Pliny we also detect signs of the conflict between science and religion. In a single chapter on God he says pretty much all that the church fathers later repeated at much greater length against paganism and polytheism. But his discussion would hardly satisfy a Christian. He asserts that “it is God for man to aid his fellow man,[127] and this is the path to eternal glory,” but he turns this noble sentiment to justify deification of the emperors who have done so much for mankind. He questions whether God is concerned with human affairs; slyly suggests that if so, God must be too busy to punish all crimes promptly; and points out that there are some things which God cannot do. He cannot commit suicide as men can, nor alter past events, nor make twice ten anything else than twenty. Pliny then concludes: “By which is revealed in no uncertain wise the power of Nature, and that is what we call God.” In many other passages he exclaims at Nature’s benignity or providence. He believed that the soul had no separate existence from the body,[128] and that after death there was no more sense left in body or soul than was there before birth. The hope of personal immortality he scorned as “puerile ravings” produced by the fear of death, and he believed still less in the possibility of any resurrection of the body. In short, natural law, me[Pg 48]chanical force, and facts capable of scientific investigation would seem to be all that he will admit and to suffice to satisfy his strong intellect. Yet we shall later find him having the greatest difficulty in distinguishing between science and magic, and giving credence to many details in science which seem to us quite as superstitious as the pagan beliefs concerning the gods which he rejected. But if any reader is inclined to belittle Pliny for this, let him first stop and think how Pliny would ridicule some modern scientists for their religious beliefs, or for their spiritualism or psychic research.

It is desirable, however, to form some estimate of Pliny’s fitness for his task in order to judge how accurate a picture of ancient science his work is. He does not seem to have had much detailed training or experience in the natural sciences himself. He writes not as a naturalist who has observed widely and profoundly the phenomena and operations of nature, but as an omnivorous reader and voluminous note-taker who owes his knowledge largely to books or hearsay, although occasionally he says “I know” instead of “they say,” or gives the results of his own observation and experience. In the main he is not a scientist himself but only a historian of science or nature; after all, his title, Natural History, is a very fitting one. The question, of course, arises whether he has sufficient scientific training to evaluate properly the work of the past. Has he read the best authors, has he noted their best passages, has he understood their meaning? Does he repeat inferior theories and omit the correcter views of certain Alexandrian scientists? These questions are hard to answer. On his behalf it may be said that he deals little with abstruse scientific theory and mainly with simple substances and geographical places, matters in which it seems difficult for him to go far astray. Scientific specialists were not numerous in those days, anyway, and science had not yet so far advanced and ramified that one man might not hope to cover the entire field and do it substantial justice. Pliny the Younger was perhaps[Pg 49] a partial judge, but he described the Natural History as “a work remarkable for its comprehensiveness and erudition, and not less varied than Nature herself.”[129]

One thing in Pliny’s favor as a compiler, besides his personal industry, unflagging interest, and apparently abundant supply of clerical assistance, is his full and honest statement of his authorities, although he adds that he has caught many authors transcribing others verbatim without acknowledgment. He has, however, great admiration for many of his authorities, exclaiming more than once at the care and diligence of the men of the past who have left nothing untried or unexperienced, from trackless mountain tops to the roots of herbs.[130] Sometimes, nevertheless, he disputes their assertions. For instance, Hippocrates said that the appearance of jaundice on the seventh day in fever is a fatal sign, “but we know some who have lived even after this.”[131] Pliny also scolds Sophocles for his falsehoods concerning amber.[132] It may seem surprising that he should expect strict scientific truth from a dramatic poet, but Pliny, like many medieval writers, seems to regard poets as good scientific authorities. In another passage he accepts Sophocles’ statement that a certain plant is poisonous, rather than the contrary view of other writers, saying “the authority of so prominent a man moves me against their opinions.”[133] He also cites Menander concerning fish and, like almost all the ancients, regards Homer as an authority on all matters.[134] Pliny sometimes cites the works of King Juba of Numidia, than whom there hardly seems to have been a greater liar in antiquity.[135] He stated among other things in a work which he wrote for Gaius Caesar, the son of Augustus, that a whale six hundred feet long and three hundred and sixty feet broad had[Pg 50] entered a river in Arabia.[136] But where should Pliny turn for sober truth? The Stoic Chrysippus prated of amulets;[137] treatises ascribed to the great philosophers Democritus and Pythagoras[138] were full of magic; and in the works of Cicero he read of a man who could see for a distance of one hundred and thirty-five miles, and in Varro that this man, standing on a Sicilian promontory, could count the number of ships sailing out of the harbor of Carthage.[139]

The Natural History has been criticized as poorly arranged and lacking in scientific classification, but this is a criticism which can be made of many works of the classical period. Their presentation is apt to be rambling and discursive rather than logical and systematic. Even Aristotle’s History of Animals is described by Lewes[140] as unclassified in its arrangement and careless in its selection of material. I have often thought that the scholastic centuries did mankind at least one service, that of teaching lecturers and writers how to arrange their material. Pliny seems rather in advance of his times in supplying full tables of contents for the busy emperor’s convenience. Valerius Soranus seems to have been the only previous Roman writer to do this. One indication of haste in composition and failure to sift and compare his material is the fact that Pliny sometimes makes or includes contradictory statements, probably taken from different authorities. On the other hand, he not infrequently alludes to previous passages in his own work, thus showing that he has his material fairly well in hand.

Pliny once said that there was no book so bad but what some good might be got from it,[141] and to the modern reader he seems almost incredibly credulous and indiscriminate in[Pg 51] his selection of material, and to lack any standard of judgment between the true and the false. Yet he often assumes an air of scepticism and censures others sharply for their credulity or exaggeration. “’Tis strange,” he remarks à propos of some tales of men transformed into wolves for nine or ten years, “how far Greek credulity has gone. No lie is so impudent that it lacks a voucher.”[142] Once he expresses his determination to include only those points on which his authorities are in agreement.[143]

On the whole, while to us to-day the Natural History seems a disorderly and indiscriminate conglomeration of fact and fiction, its defects are probably to a great extent those of its age and of the writers from whom it has borrowed. If it does not reflect the highest achievements and clearest thinking of the best scientists of antiquity—and be it said that there are a number of the Hellenistic age of whom we should know less than we do but for Pliny—it probably is a fairly faithful epitome of science and error concerning nature in his own time and the centuries preceding. At any rate it is the best portrayal that has reached us. From it we can get our background of the confusion of magic and science in the Hellenistic age, and then reveal against this setting the development of them both in the course of the Roman Empire and middle ages. Pliny gives so many items upon each point, and is so much fuller than the average ancient or medieval book of science, that he serves as a reference book, being the likeliest place to look to find duplicated some statement concerning nature by a later writer. This of course shows that such a statement did not originate with the later writer, but is not a sure sign that he copied from Pliny; they may both have used the same authorities, as seems the case with Greek authors later in the empire who probably did not know of Pliny’s work.

In the middle ages, however, Pliny had an undoubted direct influence.[144] Manuscripts of the Natural History are[Pg 52] numerous, although in a scarcely legible condition owing to corrections and emendations which enhance the obscurity of the text and perhaps do Pliny grave injustice in other respects.[145] Also many manuscripts contain only a few books or fragments of the text, so that it is possible that many medieval scholars knew their Pliny only in part.[146] This, however, can scarcely be argued from their failure to include more from him in their own works; for that might be due to their knowing the Natural History so well that they took its contents for granted and tried to include other material in their own works. In a later chapter we shall treat of The Medicine of Pliny, a treatise derived from the Natural History. Pliny’s phrase rerum natura figures as the title of several medieval encyclopedias of somewhat similar scope. And his own name was too well known in the middle ages to escape having a work on the philosopher’s stone ascribed to him.[147]

[Pg 53]

That the Natural History was well known as a whole at least by the close of the middle ages is shown by the numerous editions, some of them magnificently printed, which were turned off from the Italian presses immediately after the invention of printing. In the Magliabechian Library of Florence alone are editions printed at Venice in 1469 and 1472, at Rome in 1473 and Parma in 1481, again at Venice in 1487, 1491, and 1499, not to mention Italian translations which appeared at Venice in 1476 and 1489.[148] These editions were accompanied by some published criticism of Pliny’s statements, since in 1492 appeared at Ferrara a treatise On the Errors of Pliny and Others in Medicine by Nicholas Leonicenus of Vicenza with a dedication to Politian.[149] But two years later Pliny found a defender in Pandulph Collenucius.[150]

But Pliny’s future influence will come out repeatedly in later chapters. We shall now inquire, first, what signs of experimental science he shows, either derived from the past or added by himself. Second, what he defines as magic and what he has to say about it. Third, how much of what he supposes to be natural science must we regard as essentially magic?

It is probably only a coincidence that two medieval manuscripts close the Natural History in the midst of the seventy-sixth chapter of the last book with the words, “Experimenta pluribus modis constant.... Primum pondere.”[151] But although from the very nature of his work Pliny makes extensive use of authorities, he not infrequently manifests a realization, as one dealing with the facts of nature should, of the importance of observation and experience as means of[Pg 54] reaching the truth. The claims of many Romans of high rank to have carried their arms as far as Mount Atlas, which Pliny declares has been repeatedly shown by experience to be most fallacious, leads him to the further reflection that nowhere is a lapse of one’s credulity easier than where a dignified author supports a false statement.[152] In other passages he calls experience the best teacher in all things,[153] and contrasts unfavorably garrulity of words and sitting in schools with going to solitudes and seeking herbs at their appropriate seasons. That upon our globe the land is entirely surrounded by water does not require, he says, investigation by arguments, but is now known by experience.[154] And if the salamander really extinguished fire, it would have been tried at Rome long ago.[155] On the other hand, we find some assertions in the Natural History which Pliny might easily have tested himself and found false, such as his statement that an egg-shell cannot be broken by force or any weight unless it is tipped a little to one side.[156] Sometimes he gives his personal experience,[157] but also mentions experience in many other connections.

The word employed most of the time by Pliny to denote experience is experimentum.[158] In many passages the word does not indicate anything like a purposive, prearranged, scientific experiment in our sense of that word, but simply the ordinary experience of daily life.[159] We are also told what experti,[160] or men of experience, advise. In a number of passages, however, experimentum is used in a sense some[Pg 55]what more closely approaching our “experiment.” These are cases where something is being tested. For instance, a method of determining whether an egg is fresh or rotten by putting it in water and watching if it floats or sinks is called an experimentum.[161] That horses would whinny at no other painting of a horse than that by Apelles is spoken of as illius experimentum artis, a test of, or testimony to, his art.[162] The expression religionis experimento is applied to a religious test or ordeal by which the virginity of Claudia was vindicated.[163] The word is also used of ways of telling if unguents are good[164] and if wine is beginning to turn;[165] and of various tests of the genuineness of drugs, gems, earths, and metals.[166] It is also twice used of letting down a lighted lamp into a huge wine cask or into wells to discover if there is danger at the bottom from noxious vapors.[167] If the lamp was extinguished, it was a sign of peril to human life. Pliny further suggests purposive experimentation in speaking of experimenta to discover water under ground[168] and in grafting trees.[169]

Most of the tests and experiences thus far mentioned have been practical operations connected with husbandry and industry. But Pliny recounts one or two others which seem to have been dictated solely by scientific curiosity. He classifies the following as experimenta:[170] the sinking of a well to prove by its complete illumination that the sun casts no shadow at noon of the summer solstice; the marking of a dolphin’s tail in order to throw some light upon its length of life, should it ever be captured again, as it was three hundred years later—perhaps the experiment of longest duration on record;[171] and the casting of a man into a pit of[Pg 56] serpents at Rome to determine if he was really immune from their stings.[172]

Experimentum is employed by Pliny in a medical sense which becomes very common in the middle ages. He calls some remedies for toothache and inflamed eyes certa experimenta—sure experiences.[173] Later experimentum came to be applied to almost any recipe or remedy. Pliny, indeed, speaks of the doctors as learning at our risk and getting experience through our deaths.[174] In another passage he states more favorably that “there is no end to experimenting with everything so that even poisons are forced to cure us.”[175] He also briefly mentions the medical sect of Empirics, of whom we shall hear more from Galen. He says that they so name themselves from experiences[176] and originated at Agrigentum in Sicily under Acron and Empedocles.

Pliny is puzzled how some things which he finds stated in “authors famous for wisdom” were ever learned by experience, for example, that the star-fish has such fiery fervor that it burns everything in the sea which it touches, and digests its food instantly.[177] That adamant can be broken only by goat’s blood he thinks must have been divinely revealed, for it would hardly have been discovered by chance, and he cannot imagine that anyone would ever have thought of testing a substance of immense value in a fluid of one of the foulest of animals.[178] In several other passages he suggests chance, accident, dreams,[179] or divine revelation as the ways in which the medicinal virtues of certain simples were discovered. Recently, for example, it was discovered that the root of the wild rose is a remedy for hydrophobia by the mother of a soldier in the praetorian guard, who was warned[Pg 57] in a dream to send her son this root, which cured him and many others who have tried it since.[180] And a soldier in Pompey’s time accidentally discovered a cure for elephantiasis when he hid his face for shame in some wild mint leaves.[181] Another herb was accidentally found to be a cure for disorders of the spleen when the entrails of a sacrificial victim happened to be thrown on it and it entirely consumed the milt.[182] The healing properties of vinegar for the sting of the asp were discovered by chance in this wise. A man who was stung by an asp while carrying a leather bottle of vinegar noticed that he felt the sting only when he set the bottle down.[183] He therefore decided to try the effects of a drink of the liquid and was thereby fully cured.[184] Other remedies are learned through the experience of rustics and illiterate persons, and yet others may be discovered by observing animals who cure their ills by them.[185] Pliny’s opinion is that the animals have hit upon them by chance.

Pliny represents a number of marvelous and to us incredible things as proved by experience. Divination from thunder, for instance, is supported by innumerable experiences, public and private. In two passages out of the three mentioning experti which I cited above, those experienced persons recommended a decidedly magical sort of procedure.[186] In another passage “the experience of many” supports “a strange observance” in plucking a bud.[187] A fourth bit of magical procedure is called “marvelous but easily tested.”[188] Thus the transition is an easy one from signs of experimental science in the Natural History to our next topic, Pliny’s account of magic.

[Pg 58]

Pliny supplies some account of the origin and spread of magic[189] but a rather confused and possibly unreliable one, as he mentions two Zoroasters separated by an interval of five or six thousand years, and two Osthaneses, one of whom accompanied Xerxes, and the other Alexander, in their respective expeditions. He says, indeed, that it is not clear whether one or two Zoroasters existed. In any case magic has flourished greatly the world over for many centuries, and was founded in Persia by Zoroaster. Some other magicians of Media, Babylonia, and Assyria are mere names to Pliny; later he mentions others like Apollobeches and Dardanus. Although he thus derives magic from the orient, he appears to make no distinction, as we shall find other writers doing, between the Magi of Persia and ordinary magicians, nor does he employ the word magic in two senses. He makes it evident, however, that there have been other men who have regarded magic more favorably than he does.

Pliny next traces the spread of magic among the Greeks. He marvels at the lack of it in the Iliad and the abundance of it in the Odyssey. He is uncertain whether to class Orpheus as a magician, and mentions Thessaly as famous for its witches at least as early as the time of Menander who named one of his comedies after them. But he regards the Osthanes who accompanied Xerxes as the prime introducer of magic to the Greek-speaking world, which straightway went mad over it. In order to learn more of it, the philosophers Pythagoras, Empedocles, Democritus, and Plato went into distant exile and on their return disseminated their lore. Pliny regards the works of Democritus as the greatest single factor in that dissemination of the doctrines of magic which occurred at about the same time that medicine was being developed by the works of Hippocrates. Some[Pg 59] regarded the books on magic ascribed to Democritus as spurious, but Pliny insists that they are genuine.[190]

Outside of the Greek-speaking world, whence of course magic spread to Rome, Pliny mentions Jewish magic, represented by such names as Moses, Jannes, and Lotapes. But he holds that magic did not originate among the Hebrews until long after Zoroaster. He also speaks of the magic of Cyprus; of the Druids, who were the magicians, diviners, and medicine men of Gaul until the emperor Tiberius suppressed them; and of distant Britain.[191] Thus discordant nations and even those ignorant of one another’s existence agree the world over in their devotion to magic. From what Pliny tells us elsewhere of the Scythians we can see that the nomads of the Russian steppes and Turkestan were devoted to magic too.

It has been shown that Pliny regarded magic as a mass of doctrines formulated by a single founder and not as a gradual social evolution, just as the Greeks and Romans ascribed their laws and customs to some single legislator. He admits in a way, however, the great antiquity claimed by magic for itself, although he questions how the bulky dicta of Zoroaster and Dardanus could have been handed down by memory during so long a period. This remark again shows how little he thinks of magic as a set of social customs and attitudes perpetuated through constant and universal practice from generation to generation. Yet what he says of its widespread prevalence among unconnected peoples goes to prove this.

Pliny has a clearer comprehension of the extensive scope of magic and of its essential characteristics, at least as it was in his day. “No one should wonder,” he says, “that its authority has been very great, since alone of the arts it has[Pg 60] embraced and united with itself the three other subjects which make the greatest appeal to the human mind,” namely, medicine, religion, and the arts of divination, especially astrology. That his phrase artes mathematicas has reference to astrology is shown by his immediately continuing, “since there is no one who is not eager to learn the future about himself and who does not think that this is most truly revealed by the sky.” But magic further “promises to reveal the future by water and spheres and air and stars and lamps and basins and the blades of axes and by many other methods, besides conferences with shades from the infernal regions.” There can therefore be no doubt that Pliny regards the various arts of divination as parts of magic.

While we have heard Pliny assert in general the close connection between magic and religion, the character of the Natural History, which deals with natural rather than religious matters, does not lead him to enter into much further detail upon this point. His occasional mention of religious usages in his own day, however, supports our information from other sources that the original Roman religion was very largely composed of magic forces, rules, and ceremonial.

Nearly half the books of the Natural History deal in whole or in part with remedies for diseases, and it is therefore of the relations between magic and natural science, and more particularly between magic and medicine, that Pliny gives us the most detailed information. Indeed, he asserts that “no one doubts” that magic “originally sprang from medicine and crept in under the show of promoting health as a loftier and more sacred medicine.” Magic and medicine have developed together, and the latter is now in imminent danger of being overwhelmed by the follies of magic, which have made men doubt whether plants possess any medicinal properties.

In the opinion of many, however, magic is sound and beneficial learning. In antiquity, and for that matter at almost all times, the height of literary fame and glory has[Pg 61] been sought from that science.[192] Eudoxus would have it the most noted and useful of all schools of philosophy. Empedocles and Plato studied it; Pythagoras and Democritus perpetuated it in their writings.

But Pliny himself feels that the assertions of the books of magic are fantastic, exaggerated, and untrue. He repeatedly brands the magi or magicians as fools or impostors, and their statements as absurd and impudent tissues of lies.[193] Vanitas, or “nonsense,” is his stock-word for their beliefs.[194] Some of their writings must, in his opinion, have been dictated by a feeling of contempt and derision for humanity.[195] Nero proved the falseness of the art, for although he studied magic eagerly and with his unlimited wealth and power had every opportunity to become a skilful practitioner, he was unable to work any marvels and abandoned the attempt.[196] Pliny therefore comes to the conclusion that magic is “invalid and empty, yet has some shadows of truth, which however are due more to poisons than to magic.”[197]

The last remark brings us to charges of evil practices made against the magicians. Besides poisons, they specialize in love-potions and drugs to produce abortions;[198] and some of their operations are inhuman or obscene and abominable. They attempt baleful sorcery or the transfer of disease from one person to another.[199] Osthanes and even Democritus propound such remedies as drinking human blood or utilizing in magic compounds and ceremonies parts of the corpses of men who have been violently slain.[200] Pliny thinks that humanity owes a great debt to the Roman government[Pg 62] for abolishing those monstrous rites of human sacrifice, “in which to slay a man was thought most pious; nay more, to eat men was thought most wholesome.”[201]

Pliny nevertheless lays less stress upon the moral argument against magic as criminal or indecent than he does upon the intellectual objection to it as untrue and unscientific. Indeed, so far as decency is concerned, his own medicine will be seen to be far from prudish, while he elsewhere gives instances of magicians guarding against defilement.[202] Moreover, among the methods employed and the results sought by magic which he frequently mentions there are comparatively few that are morally objectionable, although they seem without exception false. But many of their recipes aim at the cure of disease and other worthy, or at least admissible, objects. Possibly Pliny has somewhat censored their lore and tried to exclude all criminal secrets, but his censure seems more intellectual than moral. For instance, he fills a long chapter with extracts from a treatise on the virtues of the chameleon and its parts by Democritus, whom he regards as a leading purveyor of magic lore.[203] In opening the chapter Pliny hails “with great pleasure” the opportunity to expose “the lies of Greek vanity,” but at its close he expresses a wish that Democritus himself had been touched with the branch of a palm which he said prevents immoderate loquacity. Pliny then adds more charitably, “It is evident that this man, who in other respects was a wise and most useful member of society, has erred from too great zeal in serving humanity.”

Pliny himself fails to maintain a consistently sceptical attitude towards magic. His exact attitude is often hard to determine. Often it is difficult to say whether he is speaking in sober earnest or in a tone of light and easy pleasantry and sarcasm, as in the passage just cited concerning Democritus. Another puzzling point is his frequent excuse that he will list certain assertions of the magicians in order to[Pg 63] expose or confute them. But really he usually simply sets them forth, apparently expecting that their inherent and patent absurdity will prove a sufficient refutation of them. On the rare occasions when he undertakes to indicate in what the absurdity consists his reasoning is scarcely scientific or convincing. Thus he affirms that “it is a peculiar proof of the vanity of the magicians that of all animals they most admire moles who are condemned by nature in so many ways, to perpetual blindness and to dig in the darkness as if they were buried.”[204] And he assails the belief of the magi[205] that an owl’s egg is good for diseases of the scalp by asking, “Who, I beg, could ever have seen an owl’s egg, since it is a prodigy to see the bird itself?” Moreover, he sometimes cites assertions of the magicians without any censure, apology, or expression of disbelief; and there are many other passages where it is practically impossible to tell whether he is citing the magicians or not. Sometimes he will apparently continue to refer to them by a pronoun in chapters where they have not been mentioned by name at all.[206] In other places he will imperceptibly cease to quote the magi and after an interval perhaps as imperceptibly resume citation of their doctrines.[207] It is also difficult to determine just when writers like Democritus and Pythagoras are to be regarded as representatives of magic and when their statements are accepted by Pliny as those of sound philosophers.

Perhaps, despite Pliny’s occasional brave efforts to withstand and even ridicule the assertions of the magicians, he could not free himself from a secret liking for them and more than half believed them. At any rate he believed very similar things. Even more likely is it that previous works on nature were so full of such material and the readers of his own day so interested in it, that he could not but include[Pg 64] much of it. Once he explains[208] that certain statements are scarcely to be taken seriously, yet should not be omitted, because they have been transmitted from the past. Again he begs the reader’s indulgence for similar “vanities of the Greeks,” “because this too has its value that we should know whatever marvels they have transmitted.”[209] The truth of the matter probably is that Pliny rejected some assertions of the magicians but found others acceptable; that he gets his occasional attitude of scepticism and ridicule of their doctrines from one set of authorities, and his moments of unquestioning acceptance of their statements from other authors on whom he relies. Very likely in the books which he used it often was no clearer than it is in the Natural History whether a statement was to be ascribed to the magi or not. Very possibly Pliny was as confused in his own mind concerning the entire business as he seems to be to us. He could no more keep magic out of his Natural History than poor Mr. Dick could keep Charles the First’s head out of his book. One fact at any rate stands out clearly, the prominence of magic in his encyclopedia and in the learning of his age.

Let us now further examine Pliny’s picture of magic, not as he expressly defines or censures it, but as he reflects its own assertions and purposes in his fairly numerous citations from its literature and perhaps its practice. Here I shall rather strictly limit my survey to those statements which Pliny definitely ascribes by name to the magi or magic art. The most striking fact is that the magicians are cited again and again concerning the supposed properties, virtues, and effects of things in nature—herbs, animals, and stones. These virtues are, it is true, often employed in an effort to produce wonderful results, and often too they are combined with some fantastic rite or superstitious ceremonial performed by a human agent. But in many cases either no[Pg 65] rite at all is suggested or merely some simple medicinal application; and in a few cases there is no mention of any particular operation or result, the magicians are cited simply as authorities concerning the great but unspecified virtues of natural objects. Indeed, they stand out in Pliny’s pages not as mere sorcerers or enchanters or wonder-workers, but as those who have gone the farthest and in most detail—too far and too curiously in Pliny’s opinion—into the study of medicine and of nature. Sometimes their statements, cited without censure, supplement others concerning the species under discussion;[210] sometimes they are his sole source of information on the subject in hand.[211]

Pliny connects the origin of botany rather closely with magic, mentioning Medea and Circe as early investigators of plants and Orpheus among the first writers on the subject.[212] Moreover, Pythagoras and Democritus borrowed from the magi of the orient in their works on the properties of plants.[213] There would be little profit in repeating the names of the herbs concerning which Pliny gives opinions of the magicians, inasmuch as few of them can be associated with any plants known to-day.[214] Suffice it to say that Pliny makes no objection to the herbs which they employed. Nor does he criticize their methods of employing them, although some seem superstitious enough to the modern reader. A chaplet is worn of one herb,[215] others are plucked with the left hand and with a statement of what they are to be used for, and in one case without looking backward.[216] The anemone is to be plucked when it first appears that year with a statement of its intended use, and then is to be wrapped in a red cloth and kept in the shade, and, whenever anyone falls sick of tertian or quartan fever, is to be bound on the patient’s body.[217] The heliotrope is not to be plucked at all but[Pg 66] tied in three or four knots with a prayer that the patient may recover to untie the knots.[218]

Pliny does not even object to the marvelous results which the magi think can be gained by use of herbs until towards the close of his twenty-fourth book, although already in his twentieth and twenty-first books such powers have been claimed for herbs as to make one well-favored and enable one to attain one’s desires,[219] or to give one grace and glory.[220] At the end of his twenty-fourth book[221] he states that Pythagoras and Democritus, following the magi, ascribe to herbs unusually marvelous virtues such as to freeze water, invoke spirits, force the guilty to confess by frightening them with apparitions, and impart the gift of divination. Early in his twenty-fifth book[222] Pliny suggests that some incredible effects have been attributed to herbs by the magi and their disciples, and in a later chapter[223] he describes the magi as so mad about vervain that they think that if they are anointed with it, they can gain their wishes, drive away fevers and other diseases, and make friendships. The herb should be plucked about the rising of the dog-star when there is neither sun nor moon. Honey and honeycomb should be offered to appease the earth; then the plant should be dug around with iron with the left hand and raised aloft. By the time he reaches his twenty-sixth book Pliny’s courage has risen, so to speak, enough to cause him at last to enter upon quite a tirade against “magical vanities which have been carried so far that they might destroy faith in herbs entirely.”[224] As examples he mentions herbs supposed to dry up rivers and swamps, open barred doors at their touch, turn hostile armies to flight, and supply all the needs of the ambassadors of the Persian kings. He wonders why such herbs have never been employed in Roman warfare or Italian drainage. Pliny’s only objection to magic herbs therefore seems to be the excessive powers which are claimed for some of them.[Pg 67] He adds that it would be strange that the credulity which arose from such wholesome beginnings had reached such a pitch, if human ingenuity observed moderation in anything and if the much more recent system of medicine which Asclepiades founded could not be shown to have been carried even beyond the magicians. Here again we see Pliny failing to recognize magic as a primitive social product and regarding it as a degeneration from ancient science rather than science as a comparatively modern development from it. But he may well be right in thinking that many particular far-fetched recipes and rites were the late, artificial product of over-scholarly magicians. Thus he brands as false and magical the assertion of a recent grammarian, Apion, that the herb cynocephalia is divine and a safeguard against poison, but kills the man who uproots it entirely.[225]

In a few cases Pliny objects to the animals or parts of animals employed by the magi, as in the passage already cited where he complains that they admire moles more than any other animals.[226] But his assertion is inconsistent, since he has already affirmed that they hold the hyena in most admiration of all animals on the ground that it works magic upon men.[227] Their promise of readier favor with peoples and kings to those who anoint themselves with lion’s fat, especially that between the eyebrows, he criticizes by declaring that no fat can be found there.[228] He also twits the magi for magnifying the importance of so nasty a creature as the tick.[229] They are attracted to it by the fact that it has no outlet to its body and can live only seven days even if it fasts. Whether there is any astrological significance in the number seven here Pliny does not say. He does inform us, however, that the cricket is employed in magic because it moves backward.[230] A very bizarre object employed by the Druids and other magicians is a sort of egg produced by the hissing or foam of snakes.[231] The blood of the basilisk may also be[Pg 68] classed as a rarity. Apparently animals in some way unusual are preferred in magic, like a black sheep,[232] but the logic in the reasons given by Pliny for their selection is not clear in every instance. In some other cases not criticized by Pliny[233] we have plainly enough sympathetic magic or the principle of like cures like, as when the milt of a calf or sheep is used to cure diseases of the human spleen.

The magicians, however, do not scorn to use familiar and easily obtainable animals like the goat and dog and cat. The liver and dung of a cat, a puppy’s brains, the blood and genitals of a dog, and the gall of a black male dog are among the animal substances employed.[234] Such substances as those just named are equally in demand from other animals.[235] Minute parts of animals are frequently employed by the magicians, such as the toe of an owl, the liver of a mouse given in a fig, the tooth of a live mole, the stones from young swallows’ gizzards, the eyes of river crabs.[236] Sometimes the part employed is reduced to ashes, perhaps a relic of sacrificial custom. Thus for toothache the magi inject into the ear nearer the tooth the ashes of the head of a mad dog and oil of Cyprus, while they prescribe for affections of the sinews the ashes of an owl’s head in honied wine with lily root.[237] Other living creatures which Pliny mentions as used by the magi are the salamander, earthworm, bat, scarab with reflex horns, lizard, tortoise, bed-bug, frog, and sea-urchin.[238] The dragon’s tail wrapped in a gazelle’s skin and bound on with deer-sinews cures epilepsy,[239] and a mixture of the dragon’s tongue, eyes, gall, and intestines, boiled in oil, cooled in the night air, and rubbed on morning and evening, frees one from nocturnal apparitions.[240]

Sometimes the parts of animals are bound on outside the patient’s body, sometimes the injured portion of his body[Pg 69] is merely touched with them. Once the whole house is to be fumigated with the substance in question;[241] once the walls are to be sprinkled with it; once it is to be buried under the threshold. Some instances follow of more elaborate magic ritual connected with the use of animals or parts of animals. The hyena is more easily captured by a hunter who ties seven knots in his girdle and horsewhip, and it should be captured when the moon is in the sign of Gemini and without the loss of a single hair.[242] Another bit of astrology dispensed by the magi is that the cat, whose salted liver is taken with wine for quartan fever, should have been killed under a waning moon.[243] To cure incontinence of urine one not only drinks ashes of a boar’s genitals in sweet wine, but afterwards urinates in a dog kennel and repeats the formula, “That I may not urinate like a dog in its kennel.”[244] The magicians insist that the sex of the patient be observed in administering burnt cow-dung or bull-dung in honied wine for cases of dropsy.[245] For infantile ailments the brains of a she-goat should be passed through a gold ring and dropped in the baby’s mouth before it is given its milk.[246] After the fresh milt of a sheep has been applied to the patient with the words, “This I do for the cure of the spleen,” it should be plastered into the bedroom wall and sealed with a ring, while the charm should be repeated twenty-seven times.[247] In treating sciatica[248] an earthworm should be placed in a broken wooden dish mended with an iron band, the dish should be filled with water, the worm should be buried again where it was dug up, and the water should be drunk by the patient. The eyes of river crabs are to be attached to the patient’s person before sunrise and the blinded crabs put back into the water.[249] After it has been carried around the house thrice a bat may be nailed head down outside a window as an amulet.[250] For epilepsy goat’s flesh should be[Pg 70] given which has been roasted on a funeral pyre, and the animal’s gall should not be allowed to touch the ground.[251]

Pliny occasionally speaks in a vague general way of his citations from the magi concerning the virtues of parts of animals as lies or nonsense or “portentous,” but he does not specifically criticize their procedure any more than he did their methods of employing herbs, and he does not criticize their promised results as much as he did before. Indeed, as we have already indicated, the object in a majority of cases is purely medicinal. The purpose of others is pastoral or agricultural, such as preventing goats from straying or causing swine to follow you.[252] The blood of the basilisk, however, is said to procure answers to petitions made to the powerful and prayers addressed to the gods, and to act as a safeguard against poison or sorcery (veneficiorum amuleta).[253] Invincibility is promised the wearer of the head and tail of a dragon, hairs from a lion’s forehead, a lion’s marrow, the foam of a winning horse, a dog’s claw bound in deer-skin, and the muscles alternately of a deer and a gazelle.[254] A woman will tell secrets in her sleep if the heart of an owl is applied to her right breast, and power of divination is gained by eating the still palpitating heart of a mole.[255]

In the case of stones the names are again, as in the case of herbs, of little significance for us.[256] The accompanying ritual is slight. There are one or two suspensions from the neck or elsewhere by such means as a lion’s mane—the hair of the hyena will not do at all—nor the hair of the cynocephalus and swallows’ feathers.[257] There is some use of incantations with the stones, a setting of iron for one stone, burial of another beneath a tree that it may not dull the axe, and placing another on the tongue after rinsing the mouth with honey at certain days and hours of the moon in order to acquire the gift of divination.[258] Indeed, the results promised[Pg 71] are all marvelous. The stones benefit public speakers, admit to the presence of royalty, counteract fascination and sorcery, avert hail, thunderbolts, storms, locusts, and scorpions; chill boiling water, produce family discord, render athletes invincible, quench anger and violence, make one invisible, evoke images of the gods and shades from the infernal regions.

We have yet to mention a group of magical recipes and remedies which Pliny for some reason collects in one chapter[259] but which hardly fall under any one head. A whetstone on which iron tools are sharpened, if placed without his knowledge under the pillow of a man who has been poisoned, will cause him to reveal all the circumstances of the crime. If you turn a man who has been struck by lightning over on his injured side, he will speak at once. To cure tumors in the groin, tie seven or nine knots in the remnant of a weaver’s web, naming some widow as each knot is tied. The pain is assuaged by binding to the body the nail that has been trod on. To get rid of warts, on the twentieth day of the moon lie flat in a path gazing at the moon, stretch the hands above the head and rub the warts with anything that comes to hand. A corn may be extracted successfully at the moment a star shoots. Headache may be relieved by a liniment made by pouring vinegar on door hinges or by binding a hangman’s noose about the patient’s temples. To dislodge a fish-bone stuck in the throat, plunge the feet into cold water; to dislodge some other sort of bone, place bones on the head; to dislodge a morsel of bread, stuff bits of bread into both ears. We may add from a neighboring chapter a very magical remedy for fevers, although Pliny calls it “the most modest of their promises.”[260] Toe and finger nail parings mixed with wax are to be attached ere sunrise to another person’s door in order to transfer the disease from the patient to him. Or they may be placed near an ant-hill, in which case the first ant who tries to drag one in[Pg 72]side the hill should be captured and suspended from the patient’s neck.

Such is the picture we derive from numerous passages in the Natural History of the magic art, its materials and rites, the effects it seeks to produce, and its general attitude towards nature. Besides the natural materials employed and the marvelous results sought, we have noted the frequent use of ligatures, suspensions, and amulets, the observance of astrological conditions, of certain times and numbers, rules for plucking herbs and tying knots, stress on the use of the right or left hand—in other words, on position or direction, some employment of incantations, some sacrifice and fumigation, some specimens of sympathetic magic, of the theory that “like cures like,” and of other types of magic logic.

We may now turn to the still more numerous passages of the Natural History where the magi are not cited and compare the virtues there ascribed to the things of nature and the methods employed in medicine and agriculture with those of the magicians. We shall find many striking resemblances and shall soon come to a realization that there is more magic in the Natural History which is not attributed to the magi than there is that is. Pliny did not need to warn us that medicine had been corrupted by magic; his own medicine proves it. It is this fact, that virtually his entire work is crammed with marvelous properties and fantastic ceremonial, which makes it so difficult in some places to tell when he begins to draw material from the magi and when he leaves off. By a detailed analysis of this remaining material we shall now attempt to classify the substances of which Pliny makes use and the virtues which he ascribes to them, the rites and methods of procedure by which they are employed, and certain superstitious doctrines and notions which are involved. We shall thus find that almost precisely the same factors are present in his science as in the lore of the magicians.

[Pg 73]

Of substances we may begin with animals,[261] and, before we note the human use of their virtues with its strong suggestion of magic, may remark another unscientific and superstitious feature which was very common both in ancient and medieval times. This is the tendency to humanize animals, ascribing to them conscious motives, habits, and ruses, or even moral standards and religious veneration. We shall have occasion to note the same thing in other authors and so will give but a few specimens from the many in the Natural History. Such qualities are attributed by Pliny especially to elephants, whom he ranks next to man in intelligence, and whom he represents as worshiping the stars, learning difficult tricks, and as having a sense of justice, feel[Pg 74]ing of mercy, and so on.[262] Similarly the lion has noble courage and a sense of gratitude, while the lioness is wily in the devices by which she conceals her amours with the pard.[263] A number of the devices of fishes to escape hooks and nets are repeated by Pliny from Ovid’s Halieuticon, extant only in fragments.[264] The crocodile opens its jaws to have its teeth picked by a friendly bird; but sometimes while this operation is being performed the ichneumon “darts down its throat like a javelin and eats away its intestines.”[265] Pliny also marvels at the cleverness displayed by the dragon and the elephant in their combats with one another,[266] which, however, almost invariably terminate fatally to both combatants, the elephant falling exhausted in the dragon’s coils and crushing the serpent by its weight. Others say that in the hot summer the dragons thirst for the blood of the elephant which is very cold; in their combat the elephant falls drained of its blood and crushes the dragon who is intoxicated by the same.

The dragon’s apparent knowledge that the elephant is cold-blooded leads us to a kindred topic, the remedies used by animals and often discovered by men only by seeing animals use them. This notion continued in the middle ages, as we shall see, and of course it did not originate with Pliny. As he says himself, “The ancients have recorded the remedies of wild beasts and shown how they are healed even when poisoned.”[267] Against aconite the scorpion eats white hellebore as an antidote, while the panther employs human excrement.[268] Animals prepare themselves for combats with poisonous snakes by eating certain herbs; the weasel eats rue, the tortoise and deer use two other plants, while field mice who have been stung by snakes eat condrion.[269] The hawk tears open the hawkweed and sprinkles its eyes with the juice.[270] The serpent tastes fennel when it sheds its old[Pg 75] skin.[271] Sick bears cure themselves by a diet of ants.[272] Swallows restore the sight of their young with chelidonia or swallow-wort,[273] and the historian Xanthus says that the dragon restores its dead offspring to life with an herb called balis.[274] The hippopotamus was the original discoverer of bleeding,[275] opening a vein in his leg by wounding himself on sharp reeds along the shore, and afterwards checking the flow of blood by plastering the place with mud.[276] Pliny, however, states in one passage that animals hit upon all these remedies by chance and even have to rediscover them by accident in each new case, “since,” he continues in conformity with recent animal psychologists, “reason and practice cannot be transmitted between wild beasts.”[277]

Yet in another passage Pliny deplores the spitefulness of the dog which, while men are looking, will not pluck the herb by which it cures itself of snake-bite.[278] Probably Pliny is using different authorities in the two passages. Theophrastus, the pupil of Aristotle, had written a work on Jealous Animals. More excusable than the spitefulness of the dog is the attitude of the dragon, from whose brain the gem draconitis must be taken while the dragon is alive and preferably asleep. For if the dragon feels that it is mortally wounded, it takes revenge by spoiling the gem.[279] Elephants know that men hunt them only for their tusks, and so bury these when they fall off.[280]

Animals have marvelous virtues of their own other than the medicinal uses to which men have put them. For instance, the mere glance of the basilisk is fatal, and its breath burns up vegetation and breaks rocks.[281] But the medicinal effects which Pliny ascribes to animals and parts of animals[Pg 76] are well nigh infinite. Many animal substances will have to be introduced in other connections so that we need mention now but a very few: the heads and blood of flies, honey in which bees have died, cinere genitalis asini, chicks in the egg, and thrice seven centipedes diluted with Attic honey,[282]—this last a prescription for asthma and to be taken through a reed because it blackens every dish by its contact. Another passage advises eating a rat or shrew-mouse in order to bear a baby with black eyes.[283] These items are enough to convince us that the animals and parts of animals employed by the magicians were not one whit more bizarre and nauseating than the others found in the Natural History, nor were the cures which they were expected to work any more improbable. In order to illustrate, however, the delicate distinctions which were imagined to exist not only between the virtues of different parts of the same animal, but also between slightly varied uses of the same part, we may note that scales scraped from the topmost part of a tortoise’s shell and administered in drink check sexual desire, considering which, it is, as Pliny remarks, the more marvelous that a powder made of the entire shell is reported to arouse lust.[284] But love turns readily to hatred in magic as well as in romance, and it is nothing very unusual, as we shall find in other authors, for the same thing on slight provocation to work in exactly opposite ways.

Pig grease, Pliny somewhere informs us, possesses especially strong virtue, “because that animal feeds on the roots of herbs.”[285] From the virtues of animals, therefore, let us turn to those of herbs.[286] Pliny met on every hand assertion of their wonderful powers. The empire-builders of Rome employed the sacred herbs sagmina and verbenae in their embassies and legations. The Gauls, too, use the verbena in[Pg 77] lot-casting and prophetic responses.[287] Pliny also states more sceptically that there is another root which diviners take in drink in order to feign inspiration.[288] The Scythians know of a plant which prevents hunger and thirst if held in the mouth, and of another which has the same effect upon their horses, so that they can go for twelve days without meat or drink,[289]—an exaggerated estimate of the hardihood of the mounted Asiatic nomads and their steeds. Musaeus and Hesiod say that one anointed with polion will attain fame and dignities.[290]

Pliny perhaps did not intend to subscribe fully to such statements, although he cannot be said to call many of them into question. He did complain that some writers had asserted incredible powers of herbs, such as to restore dragons or men to life or withdraw wedges from trees,[291] yet he seems on the whole in sympathy with the opinion of the majority that there is practically nothing which the force of herbs cannot accomplish. Herophilus, illustrious in medicine, had said that certain herbs were beneficial if merely trod upon, and Pliny himself says the same of more than one plant. He tells us further that binding the wild fig tree about their necks makes the fiercest bulls stand immobile;[292] that another plant subjects fractious beasts of burden to the yoke;[293] while cows who eat buprestis burst asunder.[294] Another herb contacto genitali kills any female animal.[295] Betony is considered an amulet for houses,[296] and fishermen in Pliny’s neighborhood mix a plant with chalk and scatter it on the waves.[297] “The fish dart towards it with marvelous desire and straightway float lifeless on the surface.” Dogs will not bark at persons carrying peristereos.[298] The “impious plant” prevents any human being who tastes it from having quinsy, while swine are sure to have that disease if they do not eat it.[Pg 78] Some place it in birds’ nests to prevent the voracious nestlings from strangling. Bitter almonds provide another amusing combination of effects. Eating five of them permits one to drink without experiencing intoxication, but if foxes eat them they will die unless they find water near by to drink.[299] There are some herbs which have a medicinal effect, if one merely looks at them.[300] In two cases the masculine or feminine variety of a herb is used to secure the birth of a child of the desired sex.[301]

That the plucking of herbs and digging up of roots was a process very apt to be attended by magical procedure we find abundant evidence in the Natural History. Often plants should be plucked before sunrise.[302] Twice Pliny tells us that the peony should be uprooted by night lest the woodpecker of Mars try to pick the digger’s eyes out.[303] The state of the moon is another point to be observed,[304] and once an herb is to be gathered before thunder is heard.[305] A common instruction is to pick the plant with the left hand,[306] and once with the thumb and fourth finger of the left hand.[307] Once the right hand should be stretched covertly after the fashion of a pickpocket through the left sleeve in order to pluck the plant.[308] Sometimes one faces east in plucking herbs; sometimes, west; again one is careful not to face the wind.[309] Sometimes the gatherer must not glance behind him. Sometimes he must fast before he takes the plant from the ground;[310] again he must observe a state of chastity.[311] Sometimes he should be barefoot and clothed in white; again he should remove every stitch of clothing and even his rings.[312] Sometimes the use of iron implements is forbidden; again gold or some other material is prescribed;[313] once the herb is to be dug with a nail.[314] Sometimes circles are traced[Pg 79] about the plant with the point of a sword.[315] Often the plant must not touch the ground again after it is picked,[316] presumably from a fear that its virtue would run off like an electric current. Pliny alludes at least three times[317] to the practice of herbalists of retaining portions of the herbs they sell, and then, if they are not paid in full, replanting the herb in the same spot with the idea that thereby the disease will return to plague the delinquent patient. Frequently one is directed to state why one plucks the herb or for whom it is intended.[318] In one case the digger says, “This is the herb Argemon which Minerva discovered was a remedy for swine who taste it.”[319] In another case one should salute the plant and extract its juice before saying a word; thus its virtue will be much greater.[320] In other cases, as an offering to appease the earth, the soil about the plant is soaked with hydromel three months before plucking it, or the hole left by pulling it up is filled with different kinds of grain.[321] Sometimes one sacrifices beforehand with bread and wine or prays to the gods for permission to gather the herb.[322] The customs of the Druids in gathering herbs are mentioned more than once.[323] In gathering the sacred mistletoe on the sixth day of the moon they hold sacrifices and a banquet beneath the tree.[324] Two white bulls are the victims; a priest clad in white cuts the mistletoe with a golden sickle and receives it in a white cloak.[325]

To Pliny’s discussion of herbs we may append some specimens of the employment of magic procedure in agriculture and of the superstitions of the peasantry in which his pages abound. To guard against diseases of grain the seeds before planting should be steeped in wine, the juice of a certain herb, the gall of a cow, or human urine, or[Pg 80] should be touched with the shoulders of a mole[326]—the animal whose use by the magi we heard Pliny ridicule. One should sow at the moon’s conjunction. Before the field is hoed, a frog should be carried around it and then buried in the center in an earthen vessel. But it should be disinterred before harvest lest the millet be bitter. Birds may be kept away from the grain by planting in the four corners of the field an herb whose name is unfortunately unknown to Pliny.[327] Mice are kept out by the ashes of a weasel, mildew by laurel branches, caterpillars by placing the skull of a female beast of burden upon a stick in the garden.[328] To ward off fogs and storms from orchards and vineyards a frog may be buried as directed above, or live crabs may be burnt in the trees, or a painted grape may be consecrated.[329] Suspending a frog in the granary preserves the corn stored there.[330] To keep wolves away catch one, break its legs, attach it to the ploughshare, and thus scatter its blood about the boundaries of the field; then bury the carcass at the starting-point.[331] Or consecrate at the altar of the Lar the ploughshare with which the first furrow was traced. Foxes will not touch poultry who have eaten the dried liver of a fox or who wear a bit of its skin about their necks. Fern will not spring up again if it is mowed with the edge of a reed or uprooted by a ploughshare upon which a reed has been placed.[332] Of the use of incantations in agriculture we shall treat later.

Pliny appears to have much less faith in the possession of marvelous virtues by gems than by herbs and parts of animals. He not only characterizes the powers attributed to gems by the magi and Democritus and Pythagoras as “terrible lies” and “unspeakable nonsense”;[333] but refrains from mentioning many such himself or inserts a cautious “if we believe it” or “if they tell the truth.”[334] Of the gem[Pg 81] supposed to be produced from the urine of the lynx he says, “I think that this is quite false and no gem of that name has been seen in our time. What is stated concerning its medicinal virtue is also false.”[335] To other stones, however, he ascribes various medicinal virtues, either when taken pulverized in drink or when worn as amulets.[336] A few other occult properties are stated without reservation, as that amiantus resists all sorceries,[337] that adamant expels idle fears from the mind, that sideritis produces discord and litigation, and that eumeces, placed beneath one’s pillow at night, causes oracular visions.[338] Magnets are said to differ in sex, and the belief of Theophrastus and Mucianus is repeated that certain stones bear offspring.[339]

Of the metals iron sometimes figures in Pliny’s magical procedure, as when he either prescribes or taboos the use of it in cutting herbs or killing animals. In Arcadia the yew-tree is a fatal poison to persons sleeping beneath it, but driving a copper nail into the tree makes it harmless.[340] Pliny says that gold is medicinal in many ways and in particular is applied to wounded persons and to infants as a safeguard against witchcraft.[341] Earth itself is often used to work marvels, but usually some particular portion, such as that between cart ruts or that thrown up by ants, beetles, and moles, or in the right footprint where one first heard a cuckoo sing.[342] However, the rule that an object should not touch the ground is enforced in many other connections[343] than the plucking of herbs, and Pliny twice states that the earth will not permit a serpent who has stung a human being to re-enter its hole.[344] In his discussion of metals Pliny does not allude to transmutation or alchemy, unless it be in his accounts of various fraudulent practices of workers in metal and how Caligula extracted gold from orpiment. But the following directions for preparing antimony show how[Pg 82] closely akin to magic the procedure in ancient metallurgy might be. The antimony should be coated with cow-flap and burnt in furnaces, then quenched in woman’s milk and pounded in mortars with an admixture of rain-water.[345]

Various parts and products of the human body are credited with remarkable virtues as the mention just made of woman’s milk suggests. Other passages recommend more especially the milk of a woman just delivered of a male child, but most of all that of the mother of twins.[346] Sed nihil facile reperiatur mulierum profluvio magis monstrificum, as Pliny proceeds to illustrate by numerous examples.[347] Great virtues are also attributed to the urine, particularly of a chaste boy.[348] A few other instances of remedies drawn from the human body are ear-wax or a powdered tooth against stings of scorpions and bites of snakes,[349] a man’s hair for the bite of a dog, the first hairs from a boy’s head for gout.[350] Diseases of women are prevented by wearing constantly in a bracelet the first tooth a boy loses, provided it has not touched the ground. Simply tying two fingers or toes together is recommended for tumors in the groin, catarrh, and sore eyes.[351] Or the eyes may be touched thrice with water in which the feet have been washed. Scrofula and throat diseases may be cured by the touch of the hand of one who has died an early death, although some authorities do not insist upon the circumstance of early death but direct that the corpse be of the same sex as the patient and that the diseased spot be touched with the back of the left dead hand.

Of all fluids and excretions of the human body the saliva is perhaps used most often in ancient and medieval medicine, as the custom of spitting once or thrice in administering other remedies or performing ceremonies goes to prove. The spittle of a fasting person is the more efficacious. In a chapter devoted particularly to the properties of human[Pg 83] saliva Pliny lists many diseases and woes which it alleviates.[352] In this connection he makes the following absurd assertion which he nevertheless declares is easily tested by experiment. “If a person repents of a blow given from a distance or hand-to-hand, let him spit into the palm of the hand with which he struck, and the person who has been struck will feel no resentment. This is often proved by beasts of burden who are induced to mend their pace by this method after the use of the whip has failed.” Pliny adds, however, that some persons try to increase the force of their blows by thus spitting on the hands beforehand. He also mentions as counter-charms against sorcery the practices of spitting into one’s urine or right shoe, or when crossing a dangerous spot.

The importance of the human operator as a factor in the performance of marvels, be they medical or magical, is attested by the frequent injunctions of chastity, virginity, nudity, or a state of fasting upon persons concerned in Pliny’s procedure. Sometimes they are not to glance behind them, sometimes they are to speak to no one during the operation. Pliny also mentions men who have a special capacity for wonder-working, such as Pyrrhus, the touch of whose toe had healing power,[353] those whose eyes exert strong fascination, whole tribes of serpent-charmers and venom-curers, and others whose mere presence addles the eggs beneath a setting hen.[354] The power of words spoken by men will be considered separately under the head of incantations.

While Pliny attributes the most extreme medicinal virtues to simples, he excludes from his Natural History the strange and elaborate compounds which were nevertheless so popular in the pharmacy of his age. Of one simple, laser, he says that it would be an immense task to attempt to list all the uses that it is supposed to have in compounds.[355] His position is that the simple remedies alone are the direct work of nature, while the mixtures, tablets, pills, plasters,[Pg 84] washes are artificial inventions of the apothecaries. Once when he describes a compound called “Hermesias” which aids in the generation of good and beautiful children, it seems to be borrowed by Democritus from the magi.[356] Furthermore, Pliny thinks that health can be sufficiently preserved or restored by nature’s simple remedies. Compounds are the invention of human conjecture, avarice, and impudence. Such conjecture is often false, not sufficiently taking into account the natural sympathies and antipathies of the numerous ingredients. Often compounds are inexplicable. Pliny also deplores resort to imported drugs from India, Arabia, and the Red Sea, when there are homely remedies at hand for the poorest man.[357]

We have just heard Pliny refer to the sympathies and antipathies of natural simples, and he often explains the marvelous effects of natural objects upon one another by this relation of love and hatred, friendship or repugnance, discord or concord which exists between them, which the Greeks call sympathy or antipathy, and which Heracleitus was perhaps the first philosopher to insist upon.[358] Some modern students of magic have tried to account for all magic on this theory, and Pliny states that medicine and medicines originated from it.[359]

This relationship exists between animals,—deer and snakes, for example. So great a force is it that stags track snakes to their holes and extract them thence despite all resistance by the power of their breath. This antipathy continues after death, for the sovereign remedy for snake-bite is the rennet of a fawn killed in its mother’s womb, while serpents flee from a man who wears the tooth of a deer. But antipathy may change to sympathy, for Pliny adds that in some cases certain parts of deer treated in certain ways attract serpents.[360] This force of antipathy is in[Pg 85]deed capable of taking the strangest turn. Bed-bugs, foul and disgusting as they are, heal the bite of snakes, especially asps, and sows can eat the poisonous salamander.[361] The antipathy between goats and snakes would seem almost as potent as that between deer and snakes,[362] since we are told that snake-bitten persons recover more quickly, if they frequent the stalls where goats are kept or wear as an amulet the paunch of a she-goat.

There is also “the hatred and friendship of deaf and insensible things.”[363] Instances are the magnet’s attraction for iron and the fact that adamant can be broken only by the blood of a he-goat, two stock examples of occult influence and natural marvels which continued classic in the medieval period.[364] Pliny indeed regards this last as the clearest illustration possible of the potency of sympathy and antipathy, since a substance which defies iron and fire, nature’s two most violent agents, yields to the blood of a foul animal.[365]

There is furthermore sympathy and antipathy between animate and inanimate objects. So marvelous is the antipathy of the tamarisk tree for the spleen alone of internal organs, that pigs who drink from troughs of this wood are found when slaughtered to be without spleen, and hence splenetic patients are fed from vessels of tamarisk.[366] The spleenless pig, it may be interpolated, is another commonplace of ancient and medieval science. Smearing the hives with cow dung kills other insects but stimulates the bees who have an affinity for it (cognatum hoc iis),[367] probably, although Pliny does not say so, on the theory that they are[Pg 86] spontaneously generated from it. That the wild cabbage is hostile to dogs is evidenced by the statement of Epicharmus that it cures the bite of a mad dog but kills a dog if he eats it when given to him with meat.[368] Snakes hate the ash-tree so, that if they are hemmed in by its foliage on one side and fire on the other, they flee by preference into the flames.[369] Betony, too, is so antipathetic to snakes that they lash themselves to death when a circle of it is drawn about them.[370] Scorpions cannot survive in the air of Sicily.[371] Perhaps antipathy is also the explanation of Pliny’s absurd statement that loads of apples and pears, even if there are only a few of them, are very heavy for beasts of burden.[372] Here, however, the condition may be remedied and perhaps a relationship of sympathy established by showing the beasts how few fruit there really are or by giving them some to eat. That sympathy may even attach to places or religious circumstances Pliny infers from the belief that the priestess of the earth at Aegira, when about to descend into the cave and predict, drinks without injury bull’s blood which is supposed to be a fatal poison.[373]

That like cures like, or more precisely and paradoxically that the cause of the disease will cure its own result, is another notion which Pliny’s medicine shares with magic. This is seen in the use of parts of the mad dog to cure its bite,[374] or in rubbing thighs chafed by horse-back riding with the foam from a horse’s mouth.[375] The bite of the shrew-mouse, too, is best healed by imposition of the very animal which bit you, but another shrew-mouse will do and they are kept ready in oil and mud for this purpose.[376] The sting of the phalangium may be cured by merely looking at another insect of that species, whether it be dead or alive.

From cases in which the cure for the disease is identical with its cause it is but a short step to remedies similar to[Pg 87] or in some way associated with the ailment. It seems obvious to Pliny that stone in the bladder can be broken by the herb on which grow what look exactly like pearls. “In the case of no other herb is it so evident for what medicine it is intended; its species is such that it can be recognized at once by sight without book knowledge.”[377] Similarly ophites, a marble with serpentine streaks, is used as an amulet against snake-bite.[378] Mithridates discovered that the blood of Pontic ducks should be mixed in antidotes because they live on poison.[379] Heliotrope seed looks like a scorpion’s tail; if scorpions are touched with a sprig of heliotrope they die, and they will not enter ground which has been circumscribed by it.[380] To accelerate a woman’s delivery her lover should take off his belt and gird her with it, then untie it, saying that he has bound her and will unloose her, and then he should go away.[381] An epileptic may be cured by driving an iron nail into the spot where his head rested when he fell in the fit.[382]

Other instances of association are when the remedy employed is some part of an animal who is free from the disease in question or marked by an opposite state of health. Goats and gazelles never have ophthalmia, hence various portions of their bodies are prescribed for eye diseases.[383] Eagles can gaze at the sun, therefore their gall is efficacious in eye-salves.[384] The bird called ossifrage has a single intestine which digests anything; the end of this intestine serves as an amulet against colic, and indigestion may be cured by merely holding the crop of the bird in one hand.[385] But do not hold it too long or your flesh will waste away. The virus of mares is an ingredient in a candle which makes heads of horses seem to appear when it burns;[386] while ink of the sepia is used in a candle which causes Ethiopians to be seen when it is lighted.[387] These magic candles are borrowed[Pg 88] by Pliny from the works of Anaxilaus, and we shall find them a feature of medieval collections of experiments. Earth from a cart-wheel rut is thought a remedy against the bite of the shrew-mouse because that creature is too torpid to cross such a rut;[388] and Pliny believes that none of the virtues attributed to moles by the magicians is more probable than that they are an antidote to the bite of the shrew-mouse, which shuns even ruts, whereas moles burrow freely through the soil.[389] Pliny finds incredible the assertion made by some that a ship will move more slowly if it has the right foot of a tortoise aboard,[390] but the logic of the magic seems evident enough.

In Pliny’s medicine there are a number of examples of what may be called magic transfer, in which the aim of the procedure is not to cure the disease outright but to rid the patient of it by transferring it from him to some other animal or object. Intestinal disease may be transferred to puppies who have not yet opened their eyes by pressing them to the body and giving them milk from the patient’s mouth. They will die of the disease, when its cause and exact nature may be determined by dissecting them. But finally they must be buried.[391] Griping pains in the bowels will also pass to a duck that is held against the abdomen. One may be rid of a cough by spitting in a frog’s mouth or cure catarrh by kissing a mule,[392] although in these cases we are left uninformed whether the disease passes to the animal. But if a person who has been stung by a scorpion whispers the news in the ear of an ass, the ill will be transferred to the ass.[393] A boil may be removed by rubbing nine grains of barley around it, each grain thrice with the left hand, and then throwing them all into the fire.[394] Warts are banished by touching each with a grain of the chickpea and then tying the grains up in a linen cloth and throwing them behind one.[395] If a root of asphodel is applied to sores and then hung[Pg 89] up in smoke, the sores will dry up along with the root.[396] To cure scrofulous sores some bind on as many earthworms as there are sores and let them dry up together.[397] A tooth will cease aching if the herb erigeron is dug up with iron and the patient thrice alternately touches the tooth with the root and spits, and if he then replaces the herb in the same spot and it lives.[398] If this last is a case of magic transfer, perhaps we may trace the same notion in some of the numerous instances in which Pliny directs that an animal shall be released alive after some part of it has been removed or some other medicinal use made of it.

A common characteristic of magic force and occult virtue is that it will often act at a distance or without any physical contact or direct application. This is manifested in the practice of carrying or wearing amulets, or, what is the same thing, of ligatures and suspensions, in which objects are hung from the neck or bound to some part of the body in order to ward off danger from without or cure internal disease. Instances of such practices in the Natural History are well nigh innumerable. Roots are suspended from the neck by a thread;[399] the tongue of a fox is worn in a bracelet;[400] for quinsy the throat is wound thrice with a thong of dog-skin and catarrh is relieved by winding the same about the fingers.[401] A tooth stops aching when worms are taken from a certain prickly plant, put with some bread in a pill-box, and bound to the arm on the same side of the body as the aching tooth.[402] Two bed-bugs bound to the left arm in wool stolen from shepherds are a charm against nocturnal fevers; against diurnal fevers, if wrapped in russet cloth instead.[403] The heart of a vulture is an amulet against snakes, wild beasts, robbers, and royal wrath.[404] The traveler who carries the herb artemisia feels no fatigue.[405] Injurious drugs cannot cross one’s threshold and do injury in[Pg 90] one’s household, if a sea-star is smeared with the blood of a fox and attached to the lintel or door-post with a copper nail.[406] Not only is a wreath of herbs worn for headache,[407] but a sprig of poplar held in the hand prevents chafing between the thighs.[408] Often objects are placed under one’s pillow, especially for insomnia,[409] but any psychological effect is precluded in the case where this is to be done without the patient’s knowledge.[410] All sorts of specifications are given as to the color and kind of string, cloth, skin, box, nail, ring, bracelet, and the like in which should be placed, or with which should be bound on, the various gems, herbs, and parts of animals which serve as amulets. But when we are told that a remedy for headache which always helps many consists of a little bone from a snail found between two cart ruts, passed through gold, silver, and ivory, and attached to the body with dog-skin; or that one may bind on the head with a linen cloth the head of a snail decapitated with a reed when feeding in the morning especially at full moon;[411] we feel that we have passed beyond mere amulets, ligatures, and suspensions to more elaborate minutiae of magic procedure.

Position or direction is often an important matter in Pliny’s, as in magic, ceremonial. It perhaps comes out most frequently in his specification of right or left. An aching tooth should be scarified with the left eye-tooth of a dog; a spider which is placed with oil in the ear should be caught with the left hand;[412] epilepsy may be cured if a virgin touches the sufferer with her right thumb;[413] for ophthalmia of the right eye suspend the right eye of a frog from the patient’s neck, and the left eye for the left eye;[414] for lumbago tear off an eagle’s feet away from the joint, and use the right foot for the right side and the left for pain in the left side.[415] But we have met other examples already, and[Pg 91] also cases of the use of the upper or lower part of this or that according to the corresponding location of an aching tooth in the upper or lower jaw.[416] Tracing circles with and about objects, facing towards this or that point of the compass, the prohibition against glancing behind one, and the stress laid upon finding things or killing animals between the ruts of cart wheels, are other examples of taking into consideration position and direction which we have already met with incidentally to the treatment of other topics. The prescription of a plant which has grown on the head of a statue and of another which has taken root in a sieve thrown into a hedge[417] also seem to take mere position largely into account, more so than the accompanying recommendation of an herb growing on the banks of a stream and of another growing upon a dunghill.[418]

The element of time is also important. Operations should be performed before sunrise, early in the morning, at night, and so on. The moon is especially regarded in such directions.[419] When we are informed that sufferers from quartan fever should be rubbed all over with the fat of a tortoise, we are also told that the tortoise will be fattest on the fifteenth day of the moon and that the patient should be anointed on the sixteenth.[420] But this waxing and waning of the tortoise with the moon is primarily a matter of astrology and planetary influence, under which heading we shall also later speak of Pliny’s observance of the rising of the dog-star.

Observance of number is another feature in Pliny’s ceremonial, of which we have already met instances. He also alludes to the writings of Pythagoras on the subject and ascribes to Democritus a work on the number four. Pliny’s recipes frequently recommend that the operation be thrice repeated. In the case of curing scrofula by the ashes of vipers he prescribes three fingers thereof taken in drink for[Pg 92] thrice seven days.[421] In another application of a Gallic herb with old axle-grease which has not touched iron, not only must the patient spit thrice to the right, but the remedy is more efficacious if three men representing three different nations anoint the right side with it.[422] The virtue of the number one is not, however, entirely slighted. Importance is attached to the death of a stag from a single wound.[423] Sometimes three and one are joined in the same operation, as when child-birth is aided by hurling through the house a stone or weapon by which three animals, a man, a boar, and a bear, have been killed with single blows. One of the discoveries of Pythagoras which seldom fails is that an odd number of vowels in a child’s given name portends lameness, blindness, and like incapacitation on the right side of its body, and an even number, injuries on the left side.[424] In a crown of smilax for headache there should be an odd number of leaves,[425] and in a diet of snails prescribed for stomach trouble an odd number are to be eaten.[426] For a head-wash ten green lizards are boiled in ten sextarii of oil,[427] and for an application to prevent eyelashes from growing again when they have been pulled out fifteen frogs are impaled on fifteen bulrushes.[428] The person who has tied on a certain amulet is thereafter excluded from the patient’s sight for five days.[429] And so on.

This last item suggests a further intangible factor in Pliny’s procedure, the doing of things to or for the patient without his knowledge. But this and any other incorporeal relationships existing between operator and patient should perhaps be classed under the head of sympathy and antipathy.

Closely akin to the power of numbers is that of words. Pliny once says of an incantation employed to avert hail-storms that he would not dare in seriousness to insert its[Pg 93] words, although Cato in his work on agriculture prescribed a similar formula of meaningless words for the cure of fractured limbs.[430] But Pliny does not object to the repetition of incantations or prayers if the words spoken have some meaning. He informs us that ocimum is sown with curses and maledictions and that when cummin seed is rammed down into the soil, the sowers pray it not to come up.[431] In another case the sower is to be naked and to pray for himself and his neighbors.[432] In a third case in which a poultice is to be applied to an inflammatory tumor, Pliny says that persons of experience regard it as very important that the poultice be put on by a naked virgin and that both she and the patient be fasting. Touching the sufferer with the back of her hand she is to say, “Apollo forbids a disease to increase which a naked virgin restrains.” Then, withdrawing her hand, she is to repeat the same words thrice and to join with the patient in spitting on the ground each time.[433] Indeed, in another passage Pliny states that it is the universal custom in medicine to spit three times with incantations.[434] Perhaps the power of the words is thought to be increased or renewed by clearing the throat. Words were also occasionally spoken in plucking herbs. Ring-worm or tetter is treated by spitting upon and rubbing together two stones covered with a dry white moss, and by repeating a Greek incantation which may be translated, “Flee, Cantharides, a wild wolf seeks your blood.”[435] Abscesses and inflammations are treated with the herb reseda and a Latin translation which seems irrelevant, if not quite senseless, and which may be translated, “Reseda, make disease recede. Don’t you know, don’t you know what chick has dug up these roots? May they have neither head nor feet.”[436] In the book following this passage Pliny raises the general question of the power of words to heal diseases.[437] He gives many instances of belief in incantations from contemporary popu[Pg 94]lar superstition, from Roman religion, and from the annals of history. He does not doubt that Romans in the past have believed in the power of words, and thinks that if we accept set forms of prayer and religious formulae, we must also admit the force of incantations. But he adds that the wisest individuals believe in neither.

Pliny’s recipes and operations are mainly connected with either medicine or agriculture, but he also introduces as we have seen magical procedure employed in child-birth, safeguards against poisons and reptiles, and counter-charms against sorcery. He more than once avers that love-charms (amatoria) lie outside his province,[438] in one passage alleging as a reason that the illustrious general Lucullus was killed by one,[439] but he includes a great many of them nevertheless.[440] Some herbs are so employed because of a resemblance in shape to the sexual organs,[441] another instance of association by similarity. Pliny declared against abortive drugs as well as love-charms,[442] but cited from the Commentaries of Caecilius one recipe for birth-control for the benefit of over-fecund women, consisting of a ligature of two little worms found in the body of a certain species of spider and bound on in deer-skin before sunrise. After a year the virtue of this charm expires.[443]

Pliny devotes but a small fraction of his work to the stars and heavens as against terrestrial phenomena, and therefore has less occasion to speak of astrology than of magic. However, had he been a great believer in astrology he doubtless would have devoted more space to the stars and their influence on terrestrial phenomena. He recognizes none the less, as we have seen, that magic and astrology are in[Pg 95]timately related and that “there is no one who is not eager to learn his own future and who does not think that this is shown most truly by the heavens.”[444] Parenthetically it may be remarked that the general literature of the time only confirms this assertion of the widespread prevalence of astrology; allusions of poets imply a technical knowledge of the art on their readers’ part; the very emperors who occasionally banished astrologers from Rome themselves consulted other adepts. In another passage Pliny speaks of men who “assign events each to its star according to the rules of nativities and believe that God decreed the future once for all and has never interfered with the course of events since.”[445] This way of thinking has caught learned and vulgar alike in its current and has led to such further methods of divination as those by lightning, oracles, haruspices, and even such petty auguries as from sneezes and shifting of the feet. Furthermore in Pliny’s list of men prominent in the various arts and sciences we find Berosus of whom a statue was erected by the Athenians in honor of his skill in astrological prognostication.[446] In another place where he speaks for a moment of “the science of the stars” Pliny disputes the theories of Berosus, Nechepso, and Petosiris that length of human life is ordered by the stars, and also makes the trite objection to the doctrine of nativities that masters and slaves, kings and beggars are born at the same moment.[447] He also is rather inclined to ridicule the enormous figures of 720,000 or 490,000 years set by Epigenes and Berosus and Critodemus for the duration of astronomical observations recorded by the Babylonians.[448] From such passages we get the impression that astrology is widely accepted as a science but that the art of nativities at least is not regarded by Pliny[Pg 96] with favor. But it would not be safe to say that he denies the control of the stars over human destiny. Indeed, in one chapter he declares that the astronomer Hipparchus can never be praised enough because more than any other man he proved the relationship of man with the stars and that our souls are part of the sky.[449] When Pliny disputes the vulgar notion that each man has a star varying in brightness according to his fortune, rising when he is born, and fading or falling when he dies, he is not attacking even the doctrine of nativities; he is denying that the stars are controlled by man’s fate rather than that man’s life is ordered by the stars.[450]

If Pliny thus leaves us uncertain as to the relation of man to the stars, we also receive conflicting impressions from his discussion of various celestial phenomena regarded as portentous. In one passage he speaks of the debt of gratitude owed by mankind to those great astronomical geniuses who have freed men from their former superstitious fear of eclipses.[451] But he explains thunderbolts as celestial fire vomited forth from the planet Venus and “bearing omens of the future.”[452] He also gives instances from Roman history of comets which signaled disaster, and he expounds the theory of their signifying the future.[453] What they portend may be determined from the direction in which they move and the heavenly body whose power they receive, and more particularly from the shapes they assume and their position in relation to the signs of the zodiac. Indeed, Pliny even gives examples of ominous eclipses of the sun, although it is true that they were also of unusual length.[454] He also tells us that many of the common people still believed that women could produce eclipses “by sorceries and herbs.”[455]

[Pg 97]

Aside from the question of the control of human destiny by the constellations at birth, Pliny’s general theories of the universe and of the influence of the stars upon terrestrial nature are roughly similar to those of astrology. For him the universe itself is God, “holy, eternal, vast, all in all, nay, in truth itself all;”[456] and the sun is the mind and soul of the whole world and the chief governor of nature.[457] The planets affect one another. A cold star renders another approaching it pale; a hot star causes its neighbor to redden; a windy planet gives those near it a lowering appearance.[458] At certain points in their orbits the planets are deflected from their regular course by the rays of the sun,—an unwitting concession to heliocentric theory.[459] Pliny ascribes the usual astrological qualities to the planets.[460] Saturn is cold and rigid; Mars, a flaming fire; Jupiter, located between them, is temperate and salubrious. Besides their effects upon one another, the planets especially influence the earth.[461] Venus, for instance, rules the process of generation in all terrestrial beings.[462] Following the Georgics of Vergil somewhat, Pliny asserts that the stars give indubitable signs of the weather and expounds the utility of the constellations to farmers.[463] He tells how Democritus by his knowledge of astronomy was able to corner the olive crop and put to shame business men who had been decrying philosophy;[464] and how on another occasion he gave his brother timely warning of an impending storm.[465] But Pliny does not accept all the theories of the astrologers as to control of the stars over terrestrial nature. He repeats, but without definitely accepting it, the ascription by the Babylonians of earthquakes to three of the planets in particular,[466] and the notion that the gem sandastros or garamantica, em[Pg 98]ployed by Chaldeans in their ceremonies, is intimately connected with the stars.[467] He is openly incredulous about the gem glossopetra, shaped like a human tongue and supposed to fall from the sky during an eclipse of the moon and to be invaluable in selenomancy.[468]

Pliny tells how the physician Crinas of Marseilles made a fortune by regulating diet and observing hours according to the motion of the stars.[469] But he does not show much faith in astrological medicine himself, rejecting entirely the elaborate classification of diseases and remedies which the astrologers had by his time already worked out for the revolutions of the sun and moon in the twelve signs of the zodiac.[470] In his own recipes, however, astrological considerations are sometimes observed, as we have already seen, especially the rising of the dog-star and the phases of the moon. Pliny, indeed, states that the dog-star exerts an extensive influence upon the earth.[471] As for the moon, the blood in the human body augments and decreases with its waxing and waning as shell-fish and other things in nature do.[472] Indeed, painstaking men of research had discovered that even the entrails of the field-mouse corresponded in number to the days of the moon, that the ant stopped working during the interlunar days, and that diseases of the eyes of certain beasts of burden also increased and decreased with the moon.[473] But on the whole Pliny’s medicine and science do not seem nearly so immersed in and saturated with astrology as with other forms of magic. This gap was for the middle ages amply filled by the authority of Ptolemy, of whose belief in astrology we shall treat in the next chapter.

We have tried to analyze the contents of the Natural History, bringing out certain main divisions and underlying principles of magic in Pliny’s agriculture, medicine, and natural science. This is, however, an artificial and difficult[Pg 99] task, since it is not easy to sever materials from ceremonial or the virtues of objects from the relations of sympathy or antipathy between them. Often the same passage might serve to illustrate several points. Take for example the following sentence: “Thrasyllus is authority that nothing is so hostile to serpents as crabs; swine who are stung cure themselves by this food, and when the sun is in Cancer, serpents are in pain.”[474] Here we have at once antipathy, the remedies used by animals, the reasoning, characteristic of magic, from association and similarity, and the belief in astrology. And this confusion, to illustrate which a hundred other examples might be collected from the Natural History, demonstrates how indissolubly interwoven are all the varied threads that we have been tracing. They all go naturally together, they belong to the same long period of thought, they represent the same stage in mental development, they all are parts of magic.

“When the stars twinkle through the loops of time.”

—Byron.

In this chapter we shall preface the main theme of Ptolemy and his sanction of astrology by a consideration of another and earlier ancient writer on natural science who was very favorable to divination of the future, namely, the famous philosopher, statesman, man of letters, and tutor of Nero, Lucius Annaeus Seneca. In point of time his Natural Questions, or Problems of Nature, is a work slightly antedating even the Natural History of Pliny, but it is hardly of such importance in the history of science as the more voluminous works of the three great representatives of ancient science, Pliny, Galen, and Ptolemy. Nevertheless Seneca was well known and much cited in the middle ages as an ethical or moral philosopher, and the title, Natural Questions, was to be employed by one of the first medieval pioneers of natural science, Adelard of Bath. Seneca in any case is a name of which ancient science need not be ashamed. He tells us that in his youth he had already[Pg 101] written a treatise on earthquakes;[475] and in the present treatise his aim is to inquire into the natural causes of phenomena; he wants to know why things are so. He is aware that his own age has only entered the vestibule of the knowledge of natural phenomena and forces, that it has but just begun to know five of the many stars, that “there will come a time when our descendants will wonder that we were ignorant of matters so evident.”[476]

In one passage Seneca perhaps expresses his consciousness of the very imperfect scientific knowledge of his own age a little too mystically. “There are sacred things which are not revealed all at once. Eleusis reserves sights for those who revisit her. Nature does not disclose her mysteries in a moment. We think ourselves initiated; we stand but at her portal. Those secrets open not promiscuously nor to every comer. They are remote of access, enshrined in the inner sanctuary.”[477] Indeed, he shows a tendency to regard scientific research as a sort of religious exercise or perhaps as a substitute for existing religion and a basis for moral philosophy. He relates physics to ethics. His enthusiasm in the study of natural forces appears largely due to the fact that he believes them to be of a sublime and divine character and above the petty affairs of men. He also as constantly and more fulsomely than Pliny inveighs against the luxury, vice, and immorality of his own day, and moralizes as to the beneficent influence which natural law and phenomena should exert upon human conduct. It is interesting to note that this habit of drawing moral lessons from the facts of nature was not peculiar to medieval or Christian writers.

With such subjects as zoology, botany, and mineralogy Seneca’s work has little to do; it does not, like Pliny’s[Pg 102] Natural History, include medicine and the industrial arts; neither does he, like Pliny, cite the lore of the magi. The phenomena of which he treats are mainly meteorological manifestations, such as winds, rain, hail, snow, comets, rainbows, and what he regards as allied subjects, earthquakes, springs, and rivers. Perhaps he would not have regarded the study of vegetables, animals, and minerals as so lofty and sublime a pursuit. At any rate, in consequence of the restricted field which Seneca covers we find very little of the marvelous medicinal and magical properties of plants, animals, and other objects, or the superstitious procedure which fill the pages of Pliny.

Seneca nevertheless has occasion to repeat some tall stories, such as that the river Alpheus of Greece reappears as the Arethusa in Sicily and there every four years casts up filth from its depths on the very days when victims are slaughtered at the Olympic games.[478] He also affirms that living beings are generated in fire; he believes in such effects of lightning as removing the venom from snakes which it strikes; and he recounts the old stories of floating islands and of waters with the virtue of turning white sheep black.[479] On the other hand, he qualifies by the phrases, “it is believed” and “they say,” the assertions that certain waters produce foul skin-diseases and that dew in particular, if collected in any quantity, has this evil property; and he doubts whether bathing in the Nile would enable a woman to bear more children.[480] He ridicules the custom of the city which had public watchmen appointed to warn the inhabitants of the approach of hail-storms, so that they might avert the danger by timely sacrifice or simply by pricking their own fingers so that they bled a trifle. He adds that some suggest that blood may possess some occult property of repelling storm-clouds, but he does not see how there can be such force in a drop or two and thinks it simpler to[Pg 103] regard the whole thing as false. In the same chapter he states that uncivilized antiquity used to believe that rain could be brought on or driven off by incantations, but that now-a-days no one needs a philosopher to teach him that this is impossible.[481]

But while he thus rejects incantations and is practically silent on the subject of natural magic, Seneca accepts natural divination in well-nigh all its branches: sacrificial, augury, astrology, and divination from thunder. He believes that whatever is caused is a sign of some future event.[482] Only Seneca holds that every flight of a bird is not caused by a direct act of God, nor the vitals of the victim altered under the axe by divine interference, but that all has been prearranged in a fatal and causal series.[483] He believes that all unusual celestial phenomena are to be looked upon as prodigies and portents. A meteor “as big as the moon appeared when Paulus was engaged in the war against Perseus”; similar portents marked the death of Augustus and execution of Sejanus, and gave warning of the death of Germanicus.[484] But no less truly do the planets in their unvarying courses signify the future. The stars are of divine nature, and we ought to approach the discussion of them with as reverent an air as when with lowered countenance we enter the temples for worship.[485] Not only do the stars influence the upper atmosphere as earth’s exhalations affect the lower, but they announce what is to occur.[486] Seneca employs the statement of Aristotle that comets signify the coming of storms and winds and foul weather to prove that they are stars; and declares that a comet is a portent of bad weather during the ensuing year in the same way that the Chaldeans or astrologers say that a man’s natal star determines the whole course of his life.[487] In fact, Seneca’s chief, if not sole, objection to the Chaldeans or astrologers would seem to be that in their predictions they take only five[Pg 104] stars[488] into account. “What? Think you so many thousand stars shine on in vain? What else, indeed, is it which causes those skilled in nativities to err than that they assign us to a few stars, although all those that are above us have a share in the control of our fate? Perhaps those which are nearer direct their influence upon us more closely; perhaps those of more rapid motion look down on us and other animals from more varied aspects. But even those stars that are motionless, or because of their speed keep equal pace with the rest of the universe and seem not to move, are not without rule and dominion over us.”[489] Seneca accepts the theory of Berosus that whenever all the stars are in conjunction in the sign of Cancer there will be a universal conflagration, and a second deluge when they all unite in Capricorn.[490]

It is on thunderbolts as portents of the future that Seneca dwells longest, however.[491] “They give,” he declares, “not signs of this or that event merely, but often announce a whole series of events destined to occur, and that by manifest decrees and ones far clearer than if they were set down in writing.”[492] He will not accept, however, the theory that lightning has such great power that its intervention nullifies any previous and contradictory portents. He insists that divination by other methods is of equal truth, though possibly of minor importance and significance. Next he attempts to explain how the dangers of which we are warned by divination may be averted by prayer, expiation, or sacrifice, and yet the chain of events wrought by destiny not be broken. He maintains that just as we employ the services of doctors to preserve our health, despite any belief we may have in fate, so it is useful to consult a haruspex. Then he goes on to speak of various classifications of thunderbolts according to the nature of the warnings or encouragements which they bring.

We pass on from Seneca to a later and greater exponent of natural science and divination, Ptolemy, in the follow[Pg 105]ing century. He was perhaps born at Ptolemaïs in Egypt but lived at Alexandria. The exact years of his birth and death are unknown, and very little is recorded of his life or personality. The time when he flourished is sufficiently indicated, however, by the fact that his first recorded astronomical observation was in 127 and his last in 151 A. D. Thus most of his work was probably done during the reigns of Hadrian and Antoninus Pius, but he appears to have lived on into the reign of Marcus Aurelius. His strictly scientific style scorns rhetorical devices and literary felicities, and while it is clear and correct, is dry and impersonal.[493]

Ptolemy’s two chief works, the Geography in eight books, and ἡ μαθηματικὴ σύνταξις, or Almagest (al-μεγίστη) as the Arabs called it, in thirteen books, have been so often described in histories of mathematics, astronomy, geography, and discovery that such outline of their contents need not be repeated here. The erroneous Ptolemaic theories of a geocentric universe and of an earth’s surface on which dry land preponderated are equally well known. What is more to the point at present is to note that one of these theories was so well fitted to actual scientific observations and the other was thought to be so similarly based, that they stood the test of theory, criticism, and practice for over a thousand years.[494] It should, however, be said that the Geography does not seem to have been translated into Latin until the[Pg 106] opening of the fifteenth century,[495] when Jacobus Angelus made a translation for Pope Alexander V, (1409-1410), which is extant in many manuscripts[496] as well as in print.[497] It therefore did not have the influence and fame in the Latin middle ages that the Almagest did or the briefer astrological writings, genuine and spurious, current under Ptolemy’s name.

We may briefly state one or two of Ptolemy’s greatest contributions to mathematical and natural science and his probable position in the history of experimental method. Perhaps of greater consequence in the history of science than any one specific thing he did was his continual reliance[Pg 107] upon mathematical method both in his astronomy and his geography. In particular may be noted his important contribution to trigonometry in his table of chords, which modern scholars have found correct to five decimal places, and his contribution to the science of cartography by his successful projection of spherical surfaces upon flat maps.

Ptolemy based his two great works partly upon the results already attained by earlier scientists, following Hipparchus especially in astronomy and Marinus in geography. He duly acknowledged his debts to these and other writers; praised Hipparchus and recounted his discoveries; and where he corrected Marinus, did so with reason. But while Ptolemy used previous authorities, he was far from relying upon them solely. In the Geography he adds a good deal concerning the orient and northern lands from the reports of Roman merchants and soldiers. His intention was to repeat briefly what the ancients had already made clear, and to devote his works chiefly to points which had remained obscure. His ideal was to rest his conclusions upon the surest possible observation; and where such materials were meager, as in the case of the Geography, he says so at the start. He also recognized that delicate observations should be repeated at long intervals in order to minimize the possibility of error. He devised and described some scientific instruments and conducted a long series of astronomical observations. He anteceded Comte in holding that one should adopt the simplest possible hypothesis consistent with the facts to be explained.

Besides some minor astronomical works and a treatise on music which seems to be largely a compilation an important work on optics is ascribed to Ptolemy.[498] It is the most experimental in method of his writings, although Alexander von Humboldt’s characterization of it as the only work in ancient literature which reveals an investigator of nature[Pg 108] in the act of physical experimentation[499] must be regarded as an exaggeration in view of our knowledge of the writings of other Alexandrines such as Hero and Ctesibius. As in the case of some of Ptolemy’s other minor works, the Greek original is lost and also the Arabic text from which was presumably made the medieval Latin version which alone has come down to us. Yet there are at least sixteen manuscripts of this Latin version still in existence.[500] The translation was made in the twelfth century by Eugene of Palermo, admiral of Sicily, whose name is attached to other translations and who was also the author of a number of Greek poems.[501] Heller states that the Optics was lost at the beginning of the seventeenth century but that manuscripts of it were rediscovered by Laplace and Delambre.[502] At any rate the first of the five books is no longer extant, although Bridges thinks that Roger Bacon was acquainted with it in the thirteenth century.[503] It dealt with the relations between the eye and light. In the second book conditions of visibility are discussed and the dependence of the apparent size of bodies upon the angle of vision. The third and fourth books deal with different kinds of mirrors, plane, convex, concave, conical, and pyramidical. Most important of all is the fifth and last book, in which dioptrics and refraction are discussed for the first and only time in any extant work of antiquity,[504] provided the Optics has really come down in its present form from the time of Ptolemy. His authorship has been questioned because the subject of refraction is not mentioned in the Almagest, although even astronomical refraction is discussed in the Optics.[505] De Morgan also[Pg 109] objects that the author of the Optics is inferior to Ptolemy in knowledge of geometry.[506] Possibly a work by Ptolemy has received medieval additions, either Arabic or Latin, in the version now extant; maybe the entire fifth book is such a supplement. That works which were not Ptolemy’s might be attributed to him in the middle ages is seen from the case of Hero’s Catoptrica, the Latin translation of which from the Greek is entitled in the manuscripts Ptolemaei de speculis.[507]

If there is, as in other parallel cases, the possibility that the medieval period passed off recent discoveries of its own under the authoritative name of Ptolemy, there also is the certainty that it made Ptolemy’s genuine works very much its own. This may be illustrated by the case of the Almagest. On the verge of the medieval period the work was commented upon by Pappus and Theon at Alexandria in the fourth, and by Proclus in the fifth century. The Latin translation by Boethius is not extant, but the book was in great repute among the Arabs, was translated at Bagdad early in the ninth century and revised later in the same century by Tabit ben Corra. During the twelfth century it was translated into Latin both from the Greek and the Arabic. The translation most familiar in the middle ages was that completed at Toledo in 1175 by the famous translator, Gerard of Cremona. There has recently been discovered, however, by Professors Haskins and Lockwood[508] a Sicilian translation made direct from the Greek text some ten or twelve years before Gerard’s translation. There are[Pg 110] two manuscripts of this Sicilian translation in the Vatican and one at Florence, showing that it had at least some Italian currency. Gerard’s reputation and his many other astronomical and astrological translations probably account for the greater prevalence of his version, or possibly the theological opposition to natural science of which the anonymous Sicilian translator speaks in his preface had some effect in preventing the spread of his version.

Of Ptolemy’s genuine works the most germane to and significant for our investigation is his Tetrabiblos, Quadripartitum, or four books on the control of human life by the stars. It seems to have been translated into Latin by Plato of Tivoli in the first half of the twelfth century[509] before Almagest or Geography appeared in Latin. In the middle of the thirteenth century Egidius de Tebaldis, a Lombard of the city of Parma, further translated the commentary of Haly Heben Rodan upon the Quadripartitum.[510] In the early Latin editions[511] the text is that of the medieval translation; in the few editions giving a Greek text there is a different Latin version translated directly from this Greek text.[512]

In the Tetrabiblos the art of astrology receives sanction and exposition from perhaps the ablest mathematician and closest scientific observer of the day or at least from one who seemed so to succeeding generations. Hence from that time on astrology was able to take shelter from any criticism under the aegis of his authority. Not that it lacked[Pg 111] other exponents and defenders of great name and ability. Naturally the authenticity of the Tetrabiblos has been questioned by modern admirers of Hellenic philosophy and science who would keep the reputations of the great men of the past free from all smudge of superstition. But Franz Boll has shown that it is by Ptolemy by a close comparison of it with his other works.[513] The astrological Centiloquium or Karpos, and other treatises on divination and astrological images ascribed to Ptolemy in medieval Latin manuscripts are probably spurious, but there is no doubt of his belief in astrology. German research as usual regards its favorite Posidonius as the ultimate source of much of the Tetrabiblos, but this is not a matter of much consequence for our present investigation.

In the Tetrabiblos Ptolemy first engages in argument as to the validity of the art of judicial astrology. If his remarks in this connection were not already trite contentions, they soon came to be regarded as truisms. The laws of astronomy are beyond dispute, says Ptolemy, but the art of prediction of human affairs from the courses of the stars may be assailed with more show of reason. Opponents of astrology object that the art is uncertain, and that it is useless since the events decreed by the force of the stars are inevitable. Ptolemy opens his argument in favor of the art by assuming as evident that a certain force is diffused from the heavens over all things on earth. If ignorant sailors are able to judge the future weather from the sky, a highly trained astronomer should be able to predict concerning its influence on man. The art itself should not be rejected because impostors frequently abuse it, and Ptolemy admits that it has not yet been brought to the point of perfection and that even the skilful investigator often makes mistakes owing to the incomplete state of human science. For one thing, Ptolemy regards the doctrine of the nature of matter held in his time as hypothetical rather than certain. Another difficulty is that old configurations of the stars can[Pg 112]not safely be used as the basis of present day predictions. Indeed, so manifold are the different possible positions of the stars and the different possible arrangements of terrestrial matter in relation to the stars that it is difficult to collect enough observations on which to base rules of general judgment. Moreover, such considerations as diversity of place, of custom, and of education must be taken into account in foretelling the future of different persons born under the same stars. But although for these reasons predictions frequently fail, yet the art is not to be condemned any more than one rejects the art of navigation because of frequent shipwrecks.

Nor is it true that the art is useless because the decrees of the stars are inevitable. It is often an advantage to have previous knowledge even of what cannot be avoided. Even the prediction of disaster serves to break the news gently. But not all predictions are inevitable and immutable; this is true only of the motion of the sky itself and events in which it is exclusively concerned. “But other events which do not arise solely from the sky’s motion, are easily altered by application of opposite remedies,” just as we can in part remedy the hurt of wounds and diseases or counteract the heat of summer by use of cooling things. The Egyptians have always found astrology useful in the practice of medicine.

Ptolemy next proceeds to set forth the natures and powers of the stars “according to the observations of the ancients and conformably to natural science.” Later, when he comes to the prediction of particulars, he still professes “to follow everywhere the law of natural causation,” and in a third passage he states that he “will omit all those things which do not have a probable natural cause, which many nevertheless scrutinize curiously and to excess: nor will I pile up divinations by lot-castings or from numbers, which are unscientific, but I will treat of those which have an investigated certainty based on the positions of the stars and the properties of places.” Connecting the positions of[Pg 113] the stars with earthly regions,—it is an art that fits in well with Ptolemy’s other occupations of astronomer and geographer! The Tetrabiblos has been called “Science’s surrender,”[514] but was it not more truly divination purified and made scientific?

Taking up first the properties of the seven planets, Ptolemy associates with each one or more of the four elemental qualities, hot, cold, dry, and moist. Thus the sun warms and to some extent dries, for the nearer it comes to our pole the more heat and drought it produces. The moon is moist, since it is close to the earth and is affected by the vapors from the latter, while its influence renders other bodies soft and causes putrefaction. But it also warms a little owing to the rays it receives from the sun. Saturn chills and to some extent dries, for it is remote from the sun’s heat and earth’s damp vapors. Mars emits a parching heat, as its color and proximity to the sun indicate. Jupiter, situated between cold Saturn and burning Mars, is of a rather lukewarm nature but tends more to warmth and moisture than to their opposites. So does Venus, but conversely, for it warms less than Jupiter does but moistens more, its large surface catching many vapors from the neighboring earth. In Mercury, situated near sun, moon, and earth alike, neither drought nor dampness predominates, but the velocity of that planet makes it a potent cause of sudden changes. In general, the planets exert a good or evil influence as they abound in the two rich and vivifying qualities, heat and moisture, or in the detrimental ones, cold and drought. Wet stars like the moon and Venus, are feminine; Mercury is neuter; the other planets are masculine. The sex of a planet may also, however, be reckoned according to its position in relation to the sun and the horizon; and changes in the influences exerted by the planets are noted according to their position or relation to the sun. This discussion of the properties of the planets is neither convinc[Pg 114]ing nor scientific. It seems arguing in a circle to make their effects upon the earth depend to such an extent upon themselves being affected by vapors from the earth. Indeed we are rather surprised that an astronomer like Ptolemy should represent vapors from the earth as affecting the planets at all. But his discussion is at least an effort, albeit a feeble one, to express the potencies of the planets in physical terms.

Ptolemy goes on to discuss the powers of the fixed stars which seem to depend upon their positions in constellations and their relations to the planets. Then he treats of the influence of the four seasons of the year and four cardinal points, each of which he relates to one of the four qualities, hot, cold, dry, and moist. With a discussion of the signs of the zodiac and their division into Houses and relation in Trigones or Triplicitates or groups of three connected with the four qualities, of the exaltation of the planets in the signs and of other divisions of the signs and relations of the planets to them, the first book ends.

The second book begins by distinguishing prediction of events for whole regions or countries, such as wars, pestilences, famines, earthquakes, winds, drought, and weather, from the prediction of events in the lives of individuals. Ptolemy holds that events which affect large areas or whole peoples and cities are produced by greater and more valid causes than are the acts of individual men, and also that in order to predict aright concerning the individual it is necessary to know his region and nationality. He characterizes the inhabitants of the three great climatic zones,[515] quarters the inhabited world into Europe, Libya, and two parts for Asia in the style of the T maps, and subdivides these into different countries whose peoples are described, including such races as the Amazons. The effects of the stars vary according to time as well as place, so that the period in which any individual lives is as important to take into[Pg 115] account as his nationality. Ptolemy also discusses how the heavenly bodies influence the genus of events, a matter which depends largely upon the signs of the zodiac, and also how they determine their quality, good or bad, and species, which depends on the dominant stars and their conjunctions. Consequently he gives a list of the things which belong under the rule of each planet. The remainder of the second book is concerned chiefly with prediction of wind and weather through the year and with other meteorological phenomena such as comets.

The last two books take up the prediction of events in the lives of individuals from the stars, in other words the science of nativities or genethlialogy. The third book discusses conception and birth, how to take the horoscope—Ptolemy insists that the astrolabe is the only reliable instrument for determining the exact time; sun-dials or water-clocks will not do—and how to predict concerning parents, brothers and sisters, sex, twins, monstrous births, length of life, the physical constitution of the child born and what accidents and diseases may befall it, and finally concerning mental traits and defects. The fourth book deals less with the nature of the individual and more with the prediction of external events which befall the individual: honors, office, marriage, offspring, slaves, travel, and the sort of death that he will die. Ptolemy in opening the fourth book makes the distinction that, while in the third book he treated of matters antecedent to birth or immediately related to birth or which concern the temperament of the individual, now he will deal with those external to the body and which happen to the individual from without. But of course it is difficult to maintain such a distinction with entire consistency.

The great influence of the Tetrabiblos is shown not only in medieval Arabic commentaries and Latin translations, but more immediately in the astrological writings of the declining Roman Empire, when such astrologers as Hephaes[Pg 116]tion of Thebes,[516] Paul of Alexandria, and Julius Firmicus Maternus cite it as a leading authoritative work. Only the opponents of astrology appear to have remained ignorant of the Tetrabiblos, continuing to make criticisms of the art which do not apply to Ptolemy’s presentation of it or which had been specifically answered by him. Thus Sextus Empiricus, attacking astrology about 200 A. D., does not mention the Tetrabiblos and some of the Christian critics of astrology apparently had not read it. Whether the Neo-Platonists, Porphyry and Proclus, wrote an introduction to and commentary upon it is disputed.

ἀλλ’ εἴ τις καταγνῷ μου τόδε, ὁμολογῶ τὸ πάθος τοὐμὸν ὃ παρ’ ὅλον ἐμαυτοῦ τὸν βίον ἔπαθον, οὐδενὶ πιστεύσας τῶν διηγουμένων τὰ τοιαῦτα, πρὶν πειραθῆναι καὶ αὐτὸς ὧν δυνατὸν ἦν εἰς πεῖραν ἐλθεῖν με.

Kühn, IV, 513.

διὸ κᾂν μετ’ ἐμέ τις ὁμοίως ἐμοὶ φιλόπονός τε καὶ ξηλωτικὸς ἀληθείας γένηται, μὴ προπετῶς ἐκ δυοῖν ἢ τριῶν χρήσεων ἀποφαινέσθω. πολλάκις γὰρ αὐτῷ φανεῖται διὰ τῆς μακρᾶς πείρας ὥσπερ ἐφάνη κᾀμοὶ ...

Kühn, XIII, 96-1.

χρὴ γὰρ τὸν μέλλοντα γνώσεσθαί τι τῶν πολλῶν ἄμεινον εὐθὺς μὲν καὶ τῇ φύσει καὶ τῇ πρώτῃ διδασκαλίᾳ πολὺ τῶν ἄλλων διενεγκεῖν ἐπειδὰν δὲ γένηται μειράκιον ἀληθείας τινὸς ἔχειν ἐρωτικὴν μανίαν ὥσπερ ἐνθουσιῶντα, καὶ μήθ’ ἡμέρας μήτε νυκτὸς διαλείπειν σπεύδοντά τε καὶ συντεταμένον ἐκμαθεῖν, ὅσα τοῖς ἐνδοξοτάτοις εἴρηται τῶν παλαιῶν· ἐπειδὰν δ’ ἐκμάθη, κρίνειν αὐτὰ καὶ βασανίζειν χρόνῳ παμπόλλῳ καὶ σκοπεῖν πόσα μὲν ὁμολογεῖ τοῖς ἐναργῶς φαινομένοις πόσα δὲ διαφέρεται καὶ οὕτως τὰ μὲν αἱρεῖσθαι τὰ δ’ ἀποστρέφεσθαι.

Κϋhν, II , 179.

“But if anyone charges me therewith, I confess my disease from which I have suffered all my life long, to trust none of those who make such statements until I have tested them for myself in so far as it has been possible for me to put them to the test.”

“So if anyone after me becomes like me fond of work and zealous for truth, let him not conclude hastily from two or three cases. For often he will be enlightened through long experience, just as I have been.” (It is remarkable that Ptolemy spoke similarly of his predecessor, Hipparchus, as a “lover of toil and truth”—φιλόπονον καὶ φιλαλήθεα, quoted by Orr (1913), 122.)

[Pg 119]

“For one who is to understand any matter better than most men do must straightway differ much from other persons in his nature and earliest education. And when he becomes a lad he must be madly in love with the truth and carried away by enthusiasm for it, and not let up by day or by night but press on and stretch every nerve to learn whatever the ancients of most repute have said. But having learned it, he must judge the same and put it to the test for a long, long time and observe what agrees with visible phenomena and what disagrees, and so accept the one and reject the other.”

At the close of the nineteenth century one English student of the history of medicine said, “Galen is so inaccessible to English readers that it is difficult to learn about him at first hand.”[517] Another wrote, “There is, perhaps, no other instance of a man of equal intellectual rank who has been so persistently misunderstood and even misinterpreted.”[518] A third obstacle to the ready comprehension of Galen has been that while more critical editions of some single works have been published by Helmreich and others in recent times,[519] no complete edition of his works has appeared since that of Kühn a century ago,[520] which is now regarded as very faulty.[521] A fourth reason for neglect or[Pg 120] misunderstanding of Galen is probably that there is so much by him to be read.

Athenaeus stated that Galen wrote more treatises than any other Greek, and although many are now lost, more particularly of his logical and philosophical writings, his collected extant works in Greek text and Latin translation fill some twenty volumes averaging a thousand pages each. When we add that often there are no chapter headings or other brief clues to the contents,[522] which must be ploughed through slowly and thoroughly, since some of the most valuable bits of information come in quite incidentally or by way of unlooked-for digression; that errors in the printed text, and the technical vocabulary with numerous words not found in most classical dictionaries increase the reader’s difficulties;[523] and that little if any of the text possesses any present medical value, while much of it is dreary enough reading even for one animated by historical interest, especially if one has no technical knowledge of medicine and surgery:—when we consider all these deterrents, we are not surprised that Galen is little known. “Few physicians or even scholars in the present day,” continues the English historian of medicine quoted above, “can claim to have read through this vast collection; I certainly least of all. I can only pretend to have touched the fringe, especially of the anatomical and physiological works.”[524]

[Pg 121]

Although the works of Galen are so voluminous, they have reached us for the most part in comparatively late manuscripts,[525] and to some extent perhaps only in their medieval form. The extant manuscripts of the Greek text are mostly of the fifteenth century and represent the enthusiasm of humanists who hoped by reviving the study of Galen in the original to get something new and better out of him than the schoolmen had. In this expectation they seem to have been for the most part disappointed; the middle ages had already absorbed Galen too thoroughly. If it be true, as Dr. Payne contends,[526] that the chief original contributions to medical science of the Renaissance period were the work of men trained in Greek scholarship, this was because, when they failed to get any new ideas from the Greek texts, they turned to the more promising path of experimental research which both Galen and the middle ages had already advocated. The bulky medieval Latin translations[527] of Galen are older than most of the extant Greek texts; there are also versions in Arabic and Syriac.[528] For the last five books of the Anatomical Exercises the only extant text is an Arabic manuscript not yet published.[529]

[Pg 122]

If so comparatively little is generally known about Galen, it is not because he had an unattractive personality. Nor is it difficult to make out the main events of his life. His works supply an unusual amount of personal information, and throughout his writings, unless he is merely transcribing past prescriptions, he talks like a living man, detailing incidents of daily life and making upon the reader a vivid and unaffected impression of reality. Daremberg asserts[530] that the exuberance of his imagination and his vanity frequently make us smile. It is true that his pharmacology and therapeutics often strike us as ridiculous, but he did not imagine them, they were the medicine of his age. It is true that he mentions cases which he has cured and those in which other physicians have been at fault, but official war despatches do the same with their own victories and the enemy’s defeats. Vae victis! In Galen’s case, at least, posterity long confirmed his own verdict. And dull or obsolete as his medicine now is, his scholarly and intellectual ideals and love of hard work at his art are still a living force, while the reader of his pages often feels himself carried back to the Roman world of the second century. Thus “the magic of literature,” to quote a fine sentence by Payne, “brings together thinkers widely separated in space and time.”[531]

Galen—he does not seem to have been called Claudius until the time of the Renaissance—was born about 129 A.D.[532] at Pergamum in Asia Minor. His father, Nikon, was an architect and mathematician, trained in arithmetic, geometry, and astronomy. Much of this education he transmitted to his son, but even more valuable, in Galen’s opinion, were his precepts to follow no one sect or party but to hear and judge them all, to despise honor and glory, and to magnify truth alone. To this teaching Galen attributes his own peaceful and painless passage through life. He has never[Pg 123] grieved over losses of property but managed to get along somehow. He has not minded much when some have vituperated him, thinking instead of those who praise him. In later life Galen looked back with great affection upon his father and spoke of his own great good fortune in having as a parent that gentlest, justest, most honest and humane of men. On the other hand, the chief thing that he learned from his mother was to avoid her failings of a sharp temper and tongue, with which she made life miserable for their household slaves and scolded his father worse than Xanthippe ever did Socrates.[533]

In one of his works Galen speaks of the passionate love and enthusiasm for truth which has possessed him since boyhood, so that he has not stopped either by day or by night from quest of it.[534] He realized that to become a true scholar required both high natural qualifications and a superior type of education from the start. After his fourteenth year he heard the lectures of various philosophers, Platonist and Peripatetic, Stoic and Epicurean; but when about seventeen, warned by a dream of his father,[535] he turned to the study of medicine. This incident of the dream shows that neither Galen nor his father, despite their education and intellectual standards, were free from the current belief in occult influences, of which we shall find many more instances in Galen’s works. Galen first studied medicine for four years under Satyrus in his native city of Pergamum, then under Pelops at Smyrna, later under Numisianus at Corinth and Alexandria.[536] This was about the time that the great mathematician and astronomer, Ptolemy, was completing his observations[537] in the neighborhood of Alexandria, but Galen does not mention him, despite his own belief that a first-rate physician should also know such subjects as[Pg 124] geometry and astronomy, music and rhetoric.[538] Galen’s interest in philosophy continued, however, and he wrote many logical and philosophical treatises, most of which are lost.[539] His father died when he was twenty, and it was after this that he went to other cities to study.

Galen returned to Pergamum to practice and was, when but twenty-nine, made the doctor for the gladiators by five successive pontiffs.[540] During his thirties came his first residence at Rome.[541] The article on Galen in Pauly-Wissowa states that he was driven away from Rome by the plague, and in De libris propriis he does say that, “when the great plague broke out there, I hurriedly departed from the city for my native land.”[542] But in De prognosticatione ad Epigenem his explanation is that he became disgusted with the malice of the envious physicians of the capital, and determined to return home as soon as the sedition there was over.[543] Meanwhile he stayed on and gained great fame by his cures but their jealousy and opposition multiplied, so that presently, when he learned that the sedition was over, he went back to Pergamum.

His fame, however, had come to the imperial ears and he was soon summoned to Aquileia to meet the emperors on their way north against the invading Germans. An outbreak of the plague there prevented their proceeding with the campaign immediately,[544] and Galen states that the emperors fled for Rome with a few troops, leaving the rest to suffer from the plague and cold winter. On the way Lucius Verus died, and when Marcus Aurelius finally returned to the front, he allowed Galen to go back to Rome as court[Pg 125] physician to Commodus.[545] The prevalence of the plague at this time is illustrated by a third encounter which Galen had with it in Asia, when he claims to have saved himself and others by thorough venesection.[546] The war lasted much longer than had been anticipated and meanwhile Galen was occupied chiefly in literary labors, completing a number of works. In 192 some of his writings and other treasures were lost in a fire which destroyed the Temple of Peace on the Sacred Way. Of some of the works which thus perished he had no other copy himself. In one of his works on compound medicines he explains that some persons may possess the first two books which had already been published, but that these had perished with others in a shop on the Sacra Via when the whole shrine of peace and the great libraries on the Palatine hill were consumed, and that his friends, none of whom possessed copies, had besought him to begin the work all over again.[547] Galen was still alive and writing during the early years of the dynasty of the Severi, and probably died about 200.

Although the envy of other physicians at Rome and their accusing him of resort to magic arts and divination in his marvelous prognostications and cures were perhaps neither the sole nor the true reason for Galen’s temporary withdrawal from the capital, there probably is a great deal of truth in the picture he paints of the medical profession and learned world of his day. There are too many other ancient witnesses, from the encyclopedist Pliny and the satirist Juvenal to the fourth century lawyer and astrologer, Firmicus, who substantiate his charges to permit us to explain them away as the product of personal bitterness or[Pg 126] pessimism. We feel that these men lived in an intellectual society where faction and villainy, superstition and petty-mindedness and personal enmity, were more manifest than in the quieter and, let us hope, more tolerant learned world of our time. Selfishness and pretense, personal likes and dislikes, undoubtedly still play their part, but there is not passionate animosity and open war to the knife on every hand. The status belli may still be characteristic of politics and the business world, but scholars seem able to live in substantial peace. Perhaps it is because there is less prospect of worldly gain for members of the learned professions than in Galen’s day. Perhaps it is due to the growth of the impartial scientific spirit, of unwritten codes of courtesy and ethics within the leading learned professions, and of state laws concerning such matters as patents, copyright, professional degrees, pure food, and pure drugs. Perhaps, in the unsatisfactory relations between those who should have been the best educated and most enlightened men of that time we may see an important symptom of the intellectual and ethical decline of the ancient world.

Galen states that many tire of the long struggle with crafty and wicked men which they have tried to carry on, relying upon their erudition and honest toil alone, and withdraw disgusted from the madding crowd to save themselves in dignified retirement. He especially marvels at the evil-mindedness of physicians of reputation at Rome. Though they live in the city, they are a band of robbers as truly as the brigands of the mountains. He is inclined to account for the roguery of Roman physicians compared to those of a smaller city by the facts that elsewhere men are not so tempted by the magnitude of possible gain and that in a smaller town everyone is known by everyone else and questionable practices cannot escape general notice. The rich men of Rome fall easy prey to these unscrupulous practitioners who are ready to flatter them and play up to their weaknesses. These rich men can see the use of arithmetic and geometry, which enable them to keep their books[Pg 127] straight and to build houses for their domestic comfort, and of divination and astrology, from which they seek to learn whose heirs they will be, but they have no appreciation of pure philosophy apart from rhetorical sophistry.[548]

Galen more than once complains that there are no real seekers after truth in his time, but that all are intent upon money, political power, or pleasure. You know very well, he says to one of his friends in the De methodo medendi, that not five men of all those whom we have met prefer to be rather than to seem wise.[549] Many make a great outward display and pretense in medicine and other arts who have no real knowledge.[550] Galen several times expresses his scorn for those who spend their mornings in going about saluting their friends, and their evenings in drinking bouts or in dining with the rich and powerful. Yet even his friends have reproached him for studying too much and not going out more. But while they have wasted their hours thus, he has spent his, first in learning all that the ancients have discovered that is of value, then in testing and practicing the same.[551] Moreover, now-a-days many are trying to teach others what they have never accomplished themselves.[552] Thessalus not only toadied to the rich but secured many pupils by offering to teach them medicine in six months.[553] Hence it is that tailors and dyers and smiths are abandoning their arts to become physicians. Thessalus himself, Galen ungenerously taunts, was educated by a father who plucked wool badly in the women’s apartments.[554] Indeed, Galen himself, by the violence of his invective and the occasional passionateness of his animosity in his controversies with other individuals or schools of medicine, illustrates that state of war in the intellectual world of his age to which we have adverted.

[Pg 128]

We suggested the possibility that learning compared to other occupations was more remunerative in Galen’s day than in our own, but there were poor physicians and medical students then, as well as those greedy for gain or who associated with the rich. Many doctors could not afford to use the rarer or stronger simples and limited themselves to easily procured, inexpensive, and homely medicaments.[555] Many of his fellow-students regarded as a counsel of perfection unattainable by them Galen’s plan of hearing all the different medical sects and comparing their merits and testing their validity.[556] They said tearfully that this course was all very well for him with his acute genius and his wealthy father behind him, but that they lacked the money to pursue an advanced education, perhaps had already lost valuable time under unsatisfactory teachers, or felt that they did not possess the discrimination to select for themselves what was profitable from several conflicting schools.

Galen was, it has already been made apparent, an intellectual aristocrat, and possessed little patience with those stupid men who never learn anything for themselves, though they see a myriad cures worked before their eyes. But that, apart from his own work, the medical profession was not entirely stagnant in his time, he admits when he asserts that many things are known to-day which had not been discovered before, and when he mentions some curative methods recently invented at Rome.[557]

Galen supplies considerable information concerning the drug trade in Rome itself and throughout the empire. He often complains of adulteration and fraud. The physician must know the medicinal simples and their properties himself and be able to detect adulterated medicines, or the merchants, perfumers, and herbarii will deceive him.[558] Galen refuses to reveal the methods employed in adulterating opobalsam, which he had investigated personally, lest the[Pg 129] evil practice spread further.[559] At Rome at least there were dealers in unguents who corresponded roughly to our druggists. Galen says there is not an unguent-dealer in Rome who is unacquainted with herbs from Crete, but he asserts that there are equally good medicinal plants growing in the very suburbs of Rome of which they are totally ignorant, and he taxes even those who prepare drugs for the emperors with the same oversight. He tells how the herbs from Crete come wrapped in cartons with the name of the herb written on the outside and sometimes the further statement that it is campestris.[560] These Roman drug stores seem not to have kept open at night, for Galen in describing a case speaks of the impossibility of procuring the medicines needed at once because “the lamps were already lighted.”[561]

The emperors kept a special store of drugs of their own and had botanists in Sicily, Crete, and Africa who supplied not only them with medicinal herbs, but also the city of Rome as well, Galen says. However, the emperors appear to have reserved a large supply of the finest and rarest simples for their own use. Galen mentions a large amount of Hymettus honey in the imperial stores—ἐν ταῖς αὐτοκρατορικαῖς ἀποθήκαις,[562] whence our word “apothecary.”[563] He proves that cinnamon[564] loses its potency with time by his own ex[Pg 130]perience as imperial physician. An assignment of the spice sent to Marcus Aurelius from the land of the barbarians (ἐκ τῆς βαρβάρου) was superior to what had stood stored in wooden jars from the reigns of Trajan, Hadrian, and Antoninus Pius. Commodus exhausted all the recent supply, and when Galen was forced to turn to what had been on hand in preparing an antidote for Severus, he found it much weaker than before, although not thirty years had elapsed. That cinnamon was a commodity little known to the populace is indicated by Galen’s mentioning his loss in the fire of 192 of a few precious bits of bark he had stored away in a chest with other treasures.[565] He praises the Severi, however, for permitting others to use theriac, a noted medicine and antidote of which we shall have more to say presently. Thus, he says, not only have they as emperors received power from the gods, but in sharing their goods freely they are like the gods, who rejoice the more, the more people they save.[566]

Galen himself, and apparently other physicians, were not content to rely for medicines either upon the unguent-sellers or the bounty of the imperial stores. Galen stored away oil and fat and left them to age until he had enough to last for a hundred years, including some from his father’s lifetime. He used some forty years old in one prescription.[567] He also traveled to many parts of the Roman Empire and procured rare drugs in the places where they were produced. Very interesting is his account of going out of his way in journeying back and forth between Rome and Pergamum in order to stop at Lemnos and procure a supply of the famous terra sigillata, a reddish clay stamped into pellets with the sacred seal of Diana.[568] On the way to Rome, instead of journeying on foot through Thrace and Macedonia, he took ship from the Troad to Thessalonica; but the vessel stopped[Pg 131] in Lemnos at Myrine on the wrong side of the island, which Galen had not realized possessed more than one port, and the captain would not delay the voyage long enough to enable him to cross the island to the spot where the terra sigillata was to be found. Upon his return from Rome through Macedonia, however, he took pains to visit the right port, and for the benefit of future travelers gives careful instructions concerning the route to follow and the distances between stated points. He describes the solemn procedure by which the priestess from the neighboring city gathered the red earth from the hill where it was found, sacrificing no animals, but wheat and barley to the earth. He brought away with him some twenty thousand of the little discs or seals which were supposed to cure even lethal poisons and the bite of mad dogs. The inhabitants laughed, however, at the assertion which Galen had read in Dioscorides that the seals were made by mixing the blood of a goat with the earth. Berthelot, the historian of chemistry, believed that this earth was “an oxide of iron more or less hydrated and impure.”[569] In another passage Galen advises his readers,[Pg 132] if they are ever in Pamphylia, to lay in a good supply of the drug carpesium.[570] In the ninth book of his work on medicinal simples he tells of three strata of sory, chalcite, and misy, which he had seen in a mine in Cyprus thirty years before and from which he had brought away a supply, and of the surprising chemical change which the misy underwent in the course of these years.[571]

Galen speaks of receiving other drugs from Great Syria, Palestine, Egypt, Cappadocia, Pontus, Macedonia, Gaul, Spain, and Mauretania, from the Celts, and even from India.[572] He names other places in Greece and Asia Minor than Mount Hymettus where good honey may be had, and states that much so-called Attic honey is really from the Cyclades, although it is brought to Athens and there sold or reshipped. Similarly, genuine Falernian wine is produced only in a small part of Italy, but other wines like it are prepared by those who are skilled in such knavery. As the best iris is that of Illyricum and the best asphalt is from Judea, so the best petroselinon is that of Macedonia, and merchants export it to almost the entire world just as they do Attic honey and Falernian wine. But the petroselinon crop of Epirus is sent to Thessalonica and there passed off for Macedonian. The best turpentine is that of Chios but a good variety may be obtained from Libya or Pontus. The manufacture of drugs has spread recently as well as the commerce in them. The[Pg 133] best form of unguent was formerly made only in Laodicea, but now it is similarly compounded in many other cities of Asia Minor.[573]

We are reminded that parts of animals as well as herbs and minerals were important constituents in ancient pharmacy by Galen’s invective against the frauds of hunters and dealers in wild beasts as well as of unguent-sellers. They do not hunt them at the proper season for securing their medicinal virtues, but when they are no longer in their prime or just after their long period of hibernation, when they are emaciated. Then they fatten them upon improper food, feed them barley cakes to stuff up and dull their teeth, or force them to bite frequently so that virus will run out of their mouths.[574]

Besides the ancient drug trade, Galen gives us some interesting glimpses of the publishing trade, if we may so term it, of his time. Writing in old age in the De methodo medendi,[575] he says that he has never attached his name to one of his works, never written for the popular ear or for fame, but fired by zeal for science and truth, or at the urgent request of friends, or as a useful exercise for himself, or, as now, in order to forget his old age. Popular fame is only an impediment to those who desire to live tranquilly and enjoy the fruits of philosophy. He asks Eugenianus, whom he addresses in this passage, not to praise him immoderately before men, as he has been wont to do, and not to inscribe his name in his works. His friends nevertheless prevailed upon him to write two treatises listing his works,[576] and he also is free enough in many of his books in mentioning others which are essential to read before perusing the present volume.[577] Perhaps he felt differently at different times on the question of fame and anonymity. He also objected[Pg 134] to those who read his works, not to learn anything from them, but only in order to calumniate them.[578]

It was in a shop on the Sacra Via that most of the copies of some of Galen’s works were stored when they, together with the great libraries upon the Palatine, were consumed in the fire of 192. But in another passage Galen states that the street of the Sandal-makers is where most of the bookstores in Rome are located.[579] There he saw some men disputing whether a certain treatise was his. It was duly inscribed Galenus medicus and one man, because the title was unfamiliar to him, bought it as a new work by Galen. But another man who was something of a philologer asked to see the introduction, and, after reading a few lines, declared that the book was not one of Galen’s works. When Galen was still young, he wrote three commentaries on the throat and lungs for a fellow student who wished to have something to pass off as his own work upon his return home. This friend died, however, and the books got into circulation.[580] Galen also complains that notes of his lectures which he has not intended for publication have got abroad,[581] that his servants have stolen and published some of his manuscripts, and that others have been altered, corrupted, and mutilated by those into whose possession they have come, or have been passed off by them in other lands as their own productions.[582] On the other hand, some of his pupils keep his teachings to themselves and are unwilling to give others the benefit of them, so that if they should die suddenly, his doctrines would be lost.[583] But his own ideal has always been to share his knowledge freely with those who sought it, and if possible with all mankind. At least one of Galen’s works was taken down from his dictation by short-hand writers, when, after his convincing demonstration by dissection concerning respiration and the voice, Boëthus asked him for commentaries on the subject and[Pg 135] sent for stenographers.[584] Although Galen in his travels often purchased and carried home with him large quantities of drugs, when he made his first trip to Rome he left all his books in Asia.[585]

Galen dates the falsification of title pages and contents of books back to the time when kings Ptolemy of Egypt and Attalus of Pergamum were bidding against each other for volumes for their respective libraries.[586] Works were often interpolated then in order to make them larger and so bring a better price. Galen speaks more than once of the deplorable ease with which numbers, signs, and other abbreviations are altered in manuscripts.[587] A single stroke of the pen or slight erasure will completely change the meaning of a medical prescription. He thinks that such alterations are sometimes malicious and not mere mistakes. So common were they that Menecrates composed a medical work written out entirely in complete words and entitled Autocrator Hologrammatos because it was also dedicated to the emperor. Another writer, Damocrates, from whom Galen often quotes long passages, composed his book of medicaments in metrical form so that there might be no mistake made even in complete words.

Galen’s works contain occasional historical information concerning many other matters than books and drugs. Clinton in his Fasti Romani made much use of Galen for the chronology of the period in which he lived. His allusions to several of the emperors with whom he had personal relations are valuable bits of source-material. Trajan was, of course, before his time, but he testifies to the great improvement of the roads in Italy which that emperor had effected.[588] Galen sheds a little light on the vexed question[Pg 136] of the population of the empire, if Pergamum is the place he refers to in his estimate of forty thousand citizens or one hundred and twenty thousand inhabitants, including women and slaves but perhaps not children.[589]

Galen illustrates for us the evils of ancient slavery in an incident which he relates to show the inadvisability of giving way to one’s passions, especially anger.[590] Returning from Rome, Galen fell in with a traveler from Gortyna in Crete. When they reached Corinth, the Cretan sent his baggage and slaves from Cenchrea[591] to Athens by boat, but himself with a hired vehicle and two slaves went by land with Galen through Megara, Eleusis, and Thriasa. On the way the Cretan became so angry at the two slaves that he hit them with his sheathed sword so hard that the sheath broke and they were badly wounded. Fearing that they would die, he then made off to escape the consequences of his act, leaving Galen to look after the wounded. But later he rejoined Galen in penitent mood and insisted that Galen administer a beating to him for his cruelty. Galen adds that he himself, like his father, had never struck a slave with his own hand and had reproved friends who had broken their slaves’ teeth with blows of their fists. Others go farther and kick their slaves or gouge their eyes out. The emperor Hadrian in a moment of anger is said to have blinded a slave with a stylus which he had in his hand. He, too, was sorry afterwards and offered the slave money, but the latter refused it, telling the emperor that nothing could compensate him for the loss of an eye. In another passage Galen discusses how many slaves and “clothes” one really needs.[592]

[Pg 137]

Galen also depicts the easy-going, sociable, and pleasure-loving society of his time. Not only physicians but men generally begin the day with salutations and calls, then separate again, some to the market-place and law courts, others to watch the dancers or charioteers.[593] Others play at dice or pursue love affairs, or pass the hours at the baths or in eating and drinking or some other bodily pleasure. In the evening they all come together again at symposia which bear no resemblance to the intellectual feasts of Socrates and Plato but are mere drinking bouts. Galen had no objection, however, to the use of wine in moderation and mentions the varieties from different parts of the Mediterranean world which were especially noted for their medicinal properties.[594] He believed that drinking wine discreetly relieved the mind from all worry and melancholy and refreshed it. “For we use it every day.”[595] He affirmed that taken in moderation wine aided digestion and the blood.[596] He classed wine with such boons to humanity as medicines, “a sober and decent mode of life,” and “the study of literature and liberal disciplines.”[597] Galen’s treatise in three books on food values (De alimentorum facultatibus) supplies information concerning the ancient table and dietary science.

Galen’s allusions to Judaism and Christianity are of considerable interest. He scarcely seems to have distinguished between them. In two passages in his treatise on differences in the pulse he makes incidental allusion to the followers of Moses and Christ, in both cases speaking of them rather lightly, not to say contemptuously. In criticizing Archigenes for using vague and unintelligible language and not giving a sufficient explanation of the point in question, Galen says that it is “as if one had come to a school of[Pg 138] Moses and Christ and had heard undemonstrated laws.”[598] And in criticizing opposing sects for their obstinacy he remarks that it would be easier to win over the followers of Moses and Christ.[599] Later we shall speak more fully of a third passage in De usu partium[600] where Galen criticizes the Mosaic view of the relation of God to nature, representing it as the opposite extreme to the Epicurean doctrine of a purely mechanistic and materialistic universe. This suggests that Galen had read some of the Old Testament, but he might have learned from other sources of the Dead Sea and of salts of Sodom, of which he speaks in yet another context.[601] According to a thirteenth century Arabian biographer of Galen, he spoke more favorably of Christians in a lost commentary upon Plato’s Republic, admiring their morals and admitting their miracles.[602] This last, as we shall see, is unlikely, since Galen believed in a supreme Being who worked only through natural law. “A confection of Ioachos, the martyr or metropolitan,” and “A remedy for headache of the monk Barlama” occur in the third book of the De remediis parabilibus ascribed to Galen, but this third book is greatly interpolated or entirely spurious, citing Galen himself as well as Alexander of Tralles, the sixth century writer, and mentioning the Saracens. Wellmann regards it as composed between the seventh and eleventh centuries of our era.[603]

Like most thoughtful men of his time, Galen tended to believe in one supreme deity, but he appears to have derived[Pg 139] this conception from Greek rather than Hebraic sources. It was to philosophy and the Greek mysteries that he turned for revelation of the deity, as we shall see. Hopeless criminals were for him those whom neither the Muses nor Socrates could reform.[604] It is Plato, not Christ, whom in another treatise he cites as describing the first and greatest God as ungenerated and good. “And we all naturally love Him, being such as He is from eternity.”[605]

But while Galen’s monotheism cannot be regarded as of Christian or Jewish origin, it is possible that his argument from design and supporting theology by anatomy made him more acceptable to both Mohammedan and Christian readers. At any rate he had Christian readers at Rome at the opening of the third century, when a hostile controversialist complains that some of them even worship Galen.[606] These early Christian enthusiasts for natural science, who also devoted much time to Aristotle and Euclid, were finally excommunicated; but Aristotle, Euclid, and Galen were to return in triumph in medieval learning.

Galen held as his fundamental theory of nature the view which was to prevail through the middle ages, that all natural objects upon this globe are composed of four elements, earth, air, fire, and water,[607] and the cognate view, which he says Hippocrates first introduced and Aristotle later demonstrated, that all natural objects are characterized by four qualities, hot, cold, dry, and moist. From the combinations of these four are produced various secondary qualities.[608] Neither hypothesis was as yet universally accepted, however, and Galen felt it incumbent upon him to argue against those[Pg 140] who contended that the human body and world of nature were made from but one element.[609] There were others who ridiculed the four quality hypothesis, saying that hot and cold were words for bath-keepers, not for physicians to deal with.[610] Galen explains that philosophers do not regard any particular variety of earth or any other mineral substance as representing the pure element earth, which in the philosophical sense is an extremely cold and dry substance to which adamant and rocks make perhaps the closest approach. But the earths that we see are all compound bodies.[611]

Galen rejected the atomism of Democritus and Epicurus, in which the atoms were indivisible particles differing in shape and size, but not differing in quality as chemical atoms are supposed to do. He credits Democritus with the view that such qualities as color and taste are sensed by us from the concourse of atoms, but do not reside in the atoms themselves.[612] Galen also makes the criticism that the mere regrouping of “impassive and immutable” atoms is not enough to account for the new properties of the compound, which are often very different from those of the constituents, as when “we alter the qualities of medicines in artificial mixtures.”[613] Thus he virtually says that the purely physical atomism of Democritus will not account for what to-day we call chemical change. He also, as we shall see, rejected Epicurus’ theory of a world of nature ruled by blind chance.

Galen of course thought that a dry medicine was good for a moist disease, and that in a compound medicine, by mixing a very cold with a slightly cold drug in varying proportions a medicine of any desired degree of coldness might be obtained.[614] In general he regarded solids like stones and metals as dry and cold, while he thought that hot and moist objects tended to evaporate rapidly into air.[615] So he declared that dryness of solid bodies was incurable, while he believed that children’s bodies were more easily dissolved[Pg 141] than adults’ because moister and warmer.[616] The Stoics and many physicians believed that heat prolonged life, but Asclepiades pointed out that the Ethiopians are old at thirty because the hot sun dries up their bodies so, while the inhabitants of Britain sometimes live to be one hundred and twenty years old. This last, however, was regarded as probably due to the fact that their thicker skins conserved their innate heat longer.[617]

As an offset to the evidence which will be presented later of the traces of occult virtues, magic, and astrology in Galen’s therapeutics I should like to be able to indicate the good points in it. But his entire system, like the four quality theory upon which it is largely based, seems now obsolete, and what evidenced his superiority to other physicians in his own day would probably strike the modern reader only as a token of his distinct inferiority to present practice. Eighty odd years of modern medical progress since have added further emphasis to Daremberg’s declaration that we have had to throw overboard “much of his physiology, nearly all of his pathology and general therapeutics.”[618]

Nevertheless, we may note a few specimens which perhaps represent his ordinary theory and practice as distinguished from passages in which the influence of magic enters. He holds that bleeding and cold drink are the two chief remedies for fever.[619] He notes that children occasionally resemble their grandparents rather than their parents.[620] He disputes the assertion of Epicurus—one by which some of his followers failed to be guided—that there is no benefit to health in Aphrodite, and contends that at certain intervals and in certain individuals and circumstances sexual intercourse is beneficial.[621] His discussion of anodynes and stupor or sleep-producing medicines shows that the ancients had anaesthetics of a sort.[622] He recognized the importance[Pg 142] of breathing plenty of fresh, invigorating, and unpolluted air, free from any intermixture of impurity from mines, pits, or ovens, or of putridity from decaying vegetable or animal matter, or of noxious vapors from stagnant water, swamps, and rivers.[623] As was usual in ancient and medieval times, he attributes plagues to the corruption of the air, which poisons men breathing it, and tells how Hippocrates tried to allay a plague at Athens by purifying the air by fumigation with fires, odors, and unguents.[624]

Two specimens may be given of Galen’s accounts of his own cases. In the first, some cheese, which he had told his servants to take away as too sharp, when mixed with boiled salt pork and applied to the joints, proved very helpful to a gouty patient and to several others whom he induced to try it.[625] In the second case Galen administered the following heroic treatment to a woman at Rome who was afflicted with catarrh to the point of throwing up blood.[626] He did not deem it wise to bleed her, since for four days past she had gone almost without food. Instead he ordered a sharp clyster, rubbed and bound her hands and feet with a hot drug, shaved her head and put on it a medicament made of doves’ dung. After three hours she was bathed, care being taken that nothing oily touched her head, which was then covered up. At first he fed her only gruel, afterwards some bitter autumn fruit, and as she was about to go to sleep he administered a medicament made from vipers four months before. On the second day came more rubbing and binding except the head, and at evening a somewhat smaller dose of the viper remedy. Again she slept well and in the morning he gave her a large dose of cooked honey. Again her body was well rubbed and she was given barley water and a little bread to eat. On the fourth day an older and therefore stronger variety of viper-remedy was administered and her head was covered with the same medicament as before. Its properties, Galen explains, are vehemently drying and heat[Pg 143]ing. Again she was given a bath and a little food. On the fifth day Galen ventured to purge her lungs, but he returned at intervals to the imposition upon her head. Meanwhile he continued the process of rubbing, bathing, and dieting, until finally the patient was well again,—a truly remarkable cure!

These two cases, however, do not give us a just comprehension of Galen’s abilities at their best. In his medical practice he could be as quick and comprehensive an observer and as shrewd in drawing inferences from what he observed as the famous Sherlock Holmes, so that some of his slower-witted contemporaries accused him of possessing the gift of divination. His immediate diagnosis of the case of the Sicilian physician by noting as he entered the house the excrements in a vessel which a servant was carrying out to the dungheap, and as he entered the sick-room a medicine set on the window-sill which the patient-physician had been preparing for himself, amazed the patient and the philosopher Glaucon[627] more than, let us hope in this case in view of his profession, they would have amazed the estimable Dr. Watson.

Puschmann has pointed out that Galen employs certain expressions which seem happy guesses at later discoveries. He writes: “Galen was supported in his researches by an extremely happy imaginative faculty which put the proper word in his mouth even in cases where he could not possibly arrive at a full understanding of the matter,—where he could only conjecture the truth. When, for instance, he declares that sound is carried ‘like a wave’ (Kühn, III, 644), or expresses the conjecture that the constituent of the atmosphere which is important for breathing also acts by burning (IV, 687), he expresses thoughts which startle us, for it was only possible nearly two thousand years later to understand their full significance.”[628]

[Pg 144]

Galen was keenly alive to the need of exactness in weights and measurements. He often criticizes past writers for not stating precisely what ailment the medicament recommended is good for, and in what proportions the ingredients are to be mixed. He also frequently complains because they do not specify whether they are using the Greek or Roman system of weights, or the Attic, Alexandrine, or Ephesian variety of a certain measure.[629] Moreover, he saw the desirability of more accurate means of measuring the passage of time.[630] When he states that even some illustrious physicians of his acquaintance mistake the speed of the pulse and are unable to tell whether it is slow, fast, or normal, we begin to realize something of the difficulties under which medical practice and any sort of experimentation labored before watches were invented, and how much depended upon the accuracy of human machinery and judgment. Yet Galen estimates that the chief progress made in medical prognostication since Hippocrates is the gradual development of the art of inferring from the pulse.[631] Galen tried to improve the time-pieces in use in his age. He states that in any city the inhabitants want to know the time of day accurately, not merely conjecturally; and he gives directions how to divide the day into twelve hours by a combination of a sun-dial and a clepsydra, and how on the water clock to mark the duration of the longest, shortest, and equinoctial days of the year.[632]

Delicate and difficult as was the task of measuring the pulse in Galen’s time, he was clever enough to anticipate by seventeen centuries some of the tests which modern psychologists have urged should be applied in criminal trials. He detected the fact that a female patient was not ill but in love by the quickening of her pulse when someone came in from the theater and announced that he had just seen Py[Pg 145]lades dance. When she came again the next day, Galen had purposely arranged that someone should enter and say that he had seen Morphus dancing. This and a similar test on the third day produced no perceptible quickening in the woman’s pulse. But it bounded again when on the fourth day Pylades’ name was again spoken. After recounting another analogous incident where he had been able to read the patient’s mind, Galen asks why former physicians have never availed themselves of these methods. He thinks that they must have had no conception of how the bodily health in general and the pulse in particular can be affected by the “psyche’s” suffering.[633] We might then call Galen the first experimental psychologist as well as the first to elaborate the physiology of the nervous system.

It would scarcely be fair to discuss Galen’s science at all without saying something of his remarkable work in anatomy and physiology. Daremberg went so far as to hold that all there is good or bad in his writings comes from good or bad physiology, and regarded his discussion of the bones and muscles as especially good.[634] He is generally considered the greatest anatomist of antiquity, but it is barely possible that he may have owed more to predecessors and contemporaries and less to personal research than is apparent from his own writings, which are the most complete anatomical treatises that have reached us from antiquity. Herophilus, for example, who was born at Chalcedon in the closing fourth century B. C. and flourished at Alexandria under the first Ptolemy, discovered the nerves and distinguished them from the sinews, and thought the brain the center of the nervous system, so that it is perhaps questionable whether Payne is justified in calling Galen “the founder of the physiology of the nervous system,” and in declaring that[Pg 146] “in physiological diagnosis he stands alone among the ancients.”[635] However, if Galen owed something to Herophilus, we owe much of our knowledge of the earlier physiologist to Galen.[636]

Aristotle had held that the heart was the seat of the sensitive soul[637] and the source of nervous action, “while the brain was of secondary importance, being the coldest part of the body, devoid of blood, and having for its chief or only function to cool the heart.” Galen attacked this theory by showing experimentally that “all the nerves originated in the brain, either directly or by means of the spinal cord, which he thought to be a conducting organ merely, not a center.” “A thousand times,” he says, “I have demonstrated by dissection that the cords in the heart called nerves by Aristotle are not nerves and have no connection with nerves.” He found that sensation and movement were stopped and even the voice and breathing were affected by injuries to the brain, and that an injury to one side of the brain affected the opposite side of the body. His public demonstration by dissection, performed in the presence of various philosophers and medical men, of the connection between the brain and voice and respiration and the commentaries which he immediately afterwards dictated on this point were so convincing, he tells us fifteen years later, that no one has ventured openly to dispute them.[638] His “experimental investigation of the spinal cord by sections at different levels and by half sections was still more remarkable.”[639] Galen opposed these experimental proofs to such unscientific arguments on the part of the Stoic philosopher, Chrysippus, and others, as that the heart must be the chief organ because it is in the center of the body, or because one lays[Pg 147] one’s hand on one’s heart to indicate oneself, or because the lips are moved in a certain way in saying “I” (ἐγώ).[640] Another noteworthy experiment by Galen was that in which, by binding up a section of the femoral artery he proved that the arteries contain blood and not air or spiritus as had been generally supposed.[641] He failed, however, to perform any experiments with the pulmonary veins, and so the notion persisted that these conveyed “spirit” and not blood from the lungs to the heart.[642]

It has usually been stated that Galen never dissected the human body and that his inferences by analogy from his dissection of animals involved him in serious error concerning human anatomy and physiology. Certainly he speaks as if opportunities to secure human cadavers or even skeletons were rare.[643] He mentions, however, the possibility of obtaining the bodies of criminals condemned to death or cast to beasts in the arena, or the corpses of robbers which lie unburied in the mountains, or the bodies of infants exposed by their parents.[644] It is not sufficient, he states in another passage,[645] to read books about human bones; one should have them before one’s eyes. Alexandria is the best place for the student to go to see actual exhibitions of this sort made by the teachers.[646] But even if one cannot go there, one may be able to procure human bones for oneself, as Galen did from a skeleton which had[Pg 148] been washed out of a grave by a flooded stream and from the corpse of a robber slain in the mountains. If one cannot get to see a human skeleton by these means or some other, he should dissect monkeys and apes.

Indeed Galen advises the student to dissect apes in any case, in order to prepare himself for intelligent dissection of the human body, should he ever have the opportunity. From lack of such previous experience the doctors with the army of Marcus Aurelius, who dissected the body of a dead German, learned nothing except the position of the entrails. Galen at any rate dissected a great many animals. Tiny animals and insects he let alone, for the microscope was not yet discovered, but besides apes and quadrupeds he cut up many reptiles, mice, weasels, birds, and fish.[647] He also gives an amusing account of the medical men at Rome gathering to observe the dissection of an elephant in order to discover whether the heart had one or two vertices and two or three ventricles. Galen assured them beforehand that it would be found similar to the heart of any other breathing animal. This particular dissection was not, however, performed exclusively in the interests of science, since it was scarcely accomplished when the heart was carried off, not to a scientific museum, but by the imperial cooks to their master’s table.[648] Galen sometimes dissected animals the moment he killed them. Thus he observed that the lungs always sensibly shrank from the diaphragm in a dying animal, whether he killed it by suffocation in water, or strangling with a noose, or severing the spinal medulla near the first vertebrae, or cutting the large arteries or veins.[649]

Surgical operations and medical practice were a third way of learning the human anatomy, and Galen complains of the carelessness of those physicians and surgeons who do not take pains to observe it before performing an operation or cure. He himself had had one case where the[Pg 149] human heart was laid bare and yet the patient recovered.[650] As a young practitioner before he came to Rome Galen worked out so successful a method of treating wounds of the sinews that the care of the health of the gladiators in his native city of Pergamum was entrusted to him by several successive pontifices[651] and he hardly lost a life. In the same passage he again speaks contemptuously of the doctors in the war with the Germans who were allowed to cut open the bodies of the barbarians but learned no more thereby than a cook would. When Galen came from Pergamum to Rome he found the professions of physicians and surgeons distinct and left cases to the latter which he before had attended to himself.[652] We may note finally that he invented a new form of surgical knife.[653]

In Galen’s opinion the study of anatomy was important for the philosopher as well as for the physician. An understanding of the use of the parts of the body is helpful to the doctor, he says, but much more so to “the philosopher of medicine who strives to obtain knowledge of all nature.”[654] In the De usu partium[655] he came to the conclusion that in the structure of any animal we have the mark of a wise workman or demiurge, and of a celestial mind; and that “the investigation of the use of the parts of the body lays the foundation of a truly scientific theology which is much greater and more precious than all medicine,” and which reveals the divinity more clearly than even the Eleusinian mysteries or Samothracian orgies. Thus Galen adopts the argument from design for the existence of God. The modern doctrine of evolution is of course subversive of his premise that the parts of the body are so well constructed for and marvelously adapted to their functions that nothing better is possible, and consequently of his conclusion that this necessitates a divine maker and planner.

[Pg 150]

In the treatise De foetuum formatione Galen displays a similar inclination but more tentatively and timidly. He thinks that the human body attests the wisdom and power of its maker,[656] whom he wishes the philosophers would reveal to him more clearly and tell him “whether he is some wise and powerful god.”[657] The process of the formation of the child in the womb, the complex human muscular system, the human tongue alone, seem to him so wonderful that he will not subscribe to the Epicurean denial of any all-ruling providence.[658] He thinks that nature alone cannot show such wisdom. He has, however, sought vainly from philosopher after philosopher for a satisfactory demonstration of the existence of God, and is by no means certain himself.[659]

Galen is also at a loss concerning the existence and substance of the soul. He points out that puppies try to bite before their teeth come and that calves try to hook before their horns grow, as if the soul knew the use of these parts beforehand. It might be argued that the soul itself causes the parts to grow,[660] but Galen questions this, nor is he ready to accept the Platonic world-soul theory of a divine force permeating all nature.[661] It offends his instinctive piety and sense of fitness to think of the world-soul in such things as reptiles, vermin, and putrefying corpses. On the other hand, he disagrees with those who deny any innate knowledge or standards to the soul and attribute everything to sense perception and certain imaginations and memories based thereon. Some even deny the existence of the reasoning faculty, he says, and affirm that we are led by the affections of the senses like cattle. For these men courage, prudence, temperance, continence are mere names.[662]

In commenting upon the works of Hippocrates, Galen insists that in speaking of “something divine” in diseases[Pg 151] Hippocrates could not have meant supernatural influence, which he never admits into medicine in other passages. Galen tries to explain away the expression as having reference to the effect of the surrounding air.[663] Thus while Galen might look upon nature or certain things in nature as a divine work, he would not admit any supernatural force in science or medicine, or anything bordering upon special providence. In the De usu partium Galen states that he agrees with Moses that “the beginning of genesis in all things generated” was “from the demiurge,” but that he does not agree with him that anything is possible with God and that God can suddenly turn a stone into a man or make a horse or cow from ashes. “In this matter our opinion and that of Plato and of others among the Greeks who have written correctly concerning natural science differs from the view of Moses.” In Galen’s view God attempts nothing contrary to nature but of all possible natural courses invariably chooses the best. Thus Galen expresses his admiration at nature’s providence in keeping the eyebrows and eyelashes of the same length and not letting them grow long like the beard or hair, but this is because a harder cartilaginous flesh is provided for them to grow in, and the mere will of God would not keep hairs from growing in soft flesh. If God had not provided the cartilaginous substance for the eyelashes, “he would have been more careless, not merely than Moses but than a worthless general who builds a wall in a swamp.”[664] As between the views on God of Moses and Epicurus, Galen prefers to steer a middle course.

Already in describing Galen’s dissections and tests with the pulse we have seen evidence of the accurate observation and experimental instincts which accompanied his zest for hard work and zeal for truth. In one of his treatises he[Pg 152] confesses that it was a passion of his always to test everything for himself. “And if anyone accuses me of this, I will confess my disease, from which I have suffered all my life long, that I have trusted no one of those who narrate such things until I have tested it myself, if it was possible for me to have experience of it.”[665] Galen also recognized that general theories were not sufficient for exact knowledge and that specific examples seen with one’s own eyes were indispensable.[666] He maintains that, if all teachers and writers would realize and observe this, they would make comparatively few false statements. He saw the danger of making absolute assertions and the need of noting the particular circumstances of each individual case.[667] Galen more than once declared that things, not names, were important and refused to waste time in disputing about terminology and definitions which might be spent in “pursuing the knowledge of things themselves.”[668] Thus we see in Galen a pragmatic scientist intent upon concrete facts and exact knowledge; but at the same time it must be recognized that he accepted some universal theorems and general views.

Galen did not believe in merely repeating in new books the statements of previous authorities. Ever since boyhood, he writes in his Anatomical Administrations, it has seemed to him that one should record in writing only one’s new discoveries and not repeat what has been said already.[669] Nevertheless in some of his writings he collects the prescriptions of past physicians at great length, and a previous treatise by Archigenes is practically embodied in one of Galen’s works on compound medicines. On another occasion, however, after stating that Crito had combined previous treatises upon cosmetics, including the work of Cleopatra, into four books of his own which constitute a well-nigh exhaustive treatment of the subject, Galen says that[Pg 153] he sees no profit in copying Crito’s work again and merely reproduces its table of contents.[670] On the other hand, as this passage shows, Galen thought that the ancients had stated many things admirably and he had little patience with contemporaries who would learn nothing from them but were always ambitiously weaving new and complicated dogmas, or misinterpreting and perverting the teachings of the ancients.[671] His method was rather first to “make haste and stretch every nerve to learn what the most celebrated of the ancients have said;”[672] then, having mastered this teaching, to judge it and put it to the test for a long time and determine by observation how much of it agrees and how much disagrees with actual phenomena, and then embrace the former portion and reject the latter.

This critical employment of past authorities is frequently illustrated in Galen’s works. He mentions a great many names of past physicians and writers, thereby shedding some light upon the history of Greek medicine; but at times he criticizes his predecessors, not sparing even Empedocles and Aristotle. Although he cites Aristotle a great deal, he declares that it is not surprising that Aristotle made many errors in the anatomy of animals, since he thought that the heart in large animals had a third ventricle.[673] As we have already seen in discussing the topic of weights and measurements, Galen especially objects to the vagueness and inaccuracy of many past medical writers,[674] or praises individuals like Heras who give specific information.[675] He also shows a preference for writers who give first-hand information, commending Heraclides of Tarentum as a trustworthy man, if there ever was one, who set down only those things proved by his own experience.[676] Galen declares that one could spend a lifetime in reading the books that have already been written upon medicinal simples. He urges his readers, however, to abstain from Andreas and[Pg 154] other liars of that stamp, and above all to eschew Pamphilus who never saw even in a dream the herbs which he describes.

Of all previous writers upon materia medica Galen preferred Dioscorides. He writes, “But Anazarbensis Dioscorides in five books discussed all useful material not only of herbs but of trees and fruits and juices and liquors, treating besides both all metals and the parts of animals.”[677] Yet he does not hesitate to criticize certain statements of Dioscorides, such as the story of mixing goat’s blood with the terra sigillata of Lemnos. Dioscorides had also attributed marvelous virtues to the stone Gagates which he said came from a river of that name in Lycia; Galen’s comment is that he has skirted the entire coast of Lycia in a small boat and found no such stream.[678] He also wonders that Dioscorides described butter as made of the milk of sheep and goats, and correctly states that “this drug” is made from cows’ milk.[679] Galen does not mention its use as a food in his work on medicinal simples, and in his treatise upon food values he alludes to butter rather incidentally in the chapter on milk, stating that it is a fatty substance and easily recognized by tasting it, that it has many of the properties of oil, and in cold countries is sometimes used in baths in place of oil.[680] Galen further criticizes Dioscorides for his unfamiliarity with the Greek language and consequent failure to grasp the significance of many Greek names.

Daremberg said of Galen that he represented at the same time the most exaggerated dogmatism and the most advanced experimental school. There is some justification for the paradox, though the latter part seems to me the truer. But Galen was proud of his training in philosophy and logic and mathematics; he stood fast by many Hippocratic dogmas such as the four qualities theory, he thought[681] that in medicine as in geometry there were a certain num[Pg 155]ber of self-evident maxims upon which reason, conforming to the rules of logic, might build up a scientific structure. In the De methodo medendi[682] he makes a distinction between the discovery of drugs and medicines, simple or compound, by experience and the methodical treatment of disease which he now sets forth and which should proceed logically and independently of mere empiricism, and he wishes that other medical writers would make it clear when they are relying merely on experience and when exclusively upon reason.[683] At the same time he expresses his dislike for mere dogmatizers who shout their ipse dixits like tyrants without the support either of reason or experience.[684] He also grants that the ordinary man, taught by nature alone, often instinctively pursues a better course of action for his health than “the sophists” are able to advise.[685] Indeed, he is of the opinion that some doctors would do well to stick to experience alone and not try to mix in reasoning, since they are not trained in logic, and when they endeavor to divide or analyze a theme, perform like unskilled carvers who fail to find the joints and mutilate the roast.[686] Later on in the same work[687] he again affirms that persons who will not read and profit by the books of medical authorities and whose own reasoning is defective, should limit themselves to experience.

Normally, however, Galen upholds both reason and experience as criteria of truth against the opposing schools of Dogmatics and Empirics. The former attacked experience as uncertain and impossible to regulate, slow and unmethodical. The latter replied that experience was consistent, adaptable to art, and proof enough.[688] Galen’s chief objection to the Empirics is that they reject reason as a criterion of truth and wish the medical art to be irrational.[689] “The Empirics say that all things are discovered by experi[Pg 156]ence, but we say that some are found by experience and some by reason.”[690] Galen also objects to Herodotus’s explanation of the medical art as originating in the conversation of patients exposed at crossroads who told one another of their complaints and recoveries and thus evolved a fund of common experience.[691] Galen criticizes such experience as irrational and not yet put into scientific form (οὔπω λογική). Of the Empirics he tells us further that they regard phenomena only and ignore causes and put no trust in reasoning. They hold that there is no system or necessary order in medical discovery or doctrine, and that some remedies have been discovered by dreams, others by chance. They also accepted written accounts of past experiences and thus to a certain extent trusted in tradition. Galen argues that they should test these statements of past authorities by reason.[692] His further contention that, if they test them by experience, they might as well reject all writings and trust only to present experience from the start, is a sophistical quibble unworthy of him. He adds, however, that the Empirics themselves say that past tradition or “history” (ἱστορία) should not be judged by experience, but it is unlikely that he represents their view correctly in this particular. In another passage[693] he says that they distinguish three kinds of experience, chance or accidental, offhand or impromptu, and imitative or the repetition of the same thing. In a third passage[694] he repeats that they held that observation of one or two instances was not enough, but that oft-repeated observation was needed with all conditions the same each time. In yet another place[695] he says that the Empirics observe coincidences in things joined by experience. He himself defines experience as the comprehending and remembering of something seen often and in the same condition,[696] and makes the good point that one cannot observe satisfactorily without use of reason.[697] He also admits[Pg 157] in one place that some Empirics are ready to employ reason as well as experience.[698]

Having noted Galen’s criticism of the Empirics, we may imagine what their attitude would be towards his medicine. They would probably reject all his theories—which we, too, have finally discarded—of four elements and four qualities and the like, and would accept only his specific recommendations for the cure of disease based upon his medical experience; except that they would also be credulous concerning anything which he assured them was based upon his own or another’s experience, whether it truly was or not. They would, however, have probably questioned much of his anatomical inference from the dissection of the lower animals, since he tells us that they “have written whole books against anatomy.”[699] Considering the state of knowledge in their time, their refusal to attempt any large generalizations or to hazard any scientific hypotheses or to build any risky medical system was in a way commendable, but their credulity as to particulars was a weakness.

On the whole Galen’s attitude towards experience seems an improvement upon theirs. He was apparently more critical towards the “experiences” of past writers than the average Empiric, and in his combination of reason and experience he came a little nearer to modern experimental method. Reason alone, he says, discovers some things, experience alone discovers some, but to find others requires use of both experience and reason.[700] In his treatise upon critical days he keeps reiterating that their existence is proved both by reason and experience. These two instruments in judging things given us by nature supplement each other.[701] “Logical methods have force in finding what is sought, but in believing what has been well found there are two criteria for all men, reason and experience.”[702] “What can you do with men who cannot be persuaded either by reason or by[Pg 158] practice?”[703] Galen also speaks of discovering a truth by logic and being thereby encouraged to try it in practice and of then verifying it by experience.[704] This, however, is not quite the same thing as saying that the scientist should aim to discover new truth by purposive experiments, or that from a number of experiences reason may infer some general law of nature.

It is perhaps in his work on medicinal simples that Galen lays most stress upon the importance of experience. Indeed he sees no other way to learn the properties of natural objects than through the experience of the senses.[705] “For by the gods,” he exclaims, “how is it that we know that fire is hot? Are we taught it by some syllogism or persuaded of it by some demonstration? And how do we learn that ice is cold except from the senses?”[706] And Galen sees no advantage in spending further time in arguments and hair-splitting where one can learn the truth at once from the senses. This thought he keeps repeating through the treatise, saying, for example, “The surest judge of all will be experience alone, and those who abandon it and reason on any other basis not only are deceived but destroy the value of the treatise.”[707] Moreover, he restricts his account of medicinal simples to those with which he is personally acquainted. In the three books treating of plants he does not mention all those found in all parts of the world, but only as many as it has been his privilege to know by experience.[708] He proposes to follow the same rule in the ensuing discussion of animals and to say nothing of virtues which he has not tested or of substances mentioned in the writings of past physicians but unknown to him. He dares not trust their statements when he reflects how some have lied in such matters. In the middle ages Albertus Magnus talks in much the same strain in his works on animals, plants, and minerals, and perhaps he was stimulated to such ideals, consciously or un[Pg 159]consciously, directly by reading Galen or indirectly through Arabic works, by Galen’s earlier expression of them. Galen mentions some virtues ascribed to substances which he has tested by experience and found false, such as the medicinal properties attributed to the belly of a seagull[709] and some of those claimed for the marine animal called torpedo.[710] Anointing the place with frog’s blood or dog’s milk will not prevent eyebrows that have been plucked out from growing again, nor will bat’s blood and viper’s fat remove hair from the arm-pits.[711] Also the brain of a hare is only fairly good for boys’ teeth.[712]

In beginning his work on food values[713] Galen states that many have discussed the properties of aliments, some on the basis of reason alone, some on the basis of experience alone, but that their statements do not agree. On the whole, since reasoning is not easy for everyone, requiring natural sagacity and training from childhood, he thinks it better to start from experience, especially since not a few physicians are of the opinion that only thus can the properties of foods be learned.

The Empirics contended that most compound medicines had been hit upon by chance, and Galen grants that the Dogmatics usually are unable to give reasons for the ingredients of their doses and find difficulty in reproducing a lost prescription.[714] But he holds that reasons can be given for the constituents of the compound and that the logical discovery of such remedies differs from the empirical.[715] His own method was to learn the nature of each disease and the varied properties of simples, and then prepare a compound suited to the disease and to the patient.[716] On the other hand, we see how much depends upon experience from his confession that sometimes he has hastily prepared a compound from a few simples, sometimes from more, sometimes from a great variety. If the compound worked well, he would[Pg 160] continue to use it, sometimes making it stronger and sometimes weaker.[717] For as you cannot put together compounds without rational method, so you cannot tell their strength certainly and accurately without experience.[718] He admits that no one can tell the exact quantity of each ingredient to employ without the aid of experience,[719] and says, “The proper proportions in the mixture we shall find conjecturally before experience, scientifically after experience.”[720] In these treatises upon compound medicines, unlike that on medicinal simples, Galen gives the prescriptions of former physicians as well as some tested by his own experience.[721] Sometimes, however, he expresses a preference for the medicines of those writers who were “most experienced”; and once says that he will give some compounds of the more recent writers, who in their turn had selected the best from older writers of long experience and added later discoveries.[722] We suspect, however, that some of these prescriptions had not been tested for centuries.

Galen gives a few directions how to regulate medical observation and experience, although they cannot be said to carry us very far on the road to modern laboratory research. He saw the value of “long experience,” a phrase which he often employs.[723] He states that one experience is enough to learn how to prepare a drug, but to learn to know the best medicines in each kind and in different places many experiences are required.[724] Medicinal simples should be frequently inspected, “since the knowledge of things perceived by the senses is strengthened by careful examination.”[725] Galen advises the student of medicine to study herbs, trees, and fruit as they grow, to find out when it is best to pluck them, how to preserve them, and so on. But elsewhere he states that it is possible to estimate the general virtue of the simple[Pg 161] from one or two experiences.[726] However, he suggests that their effect be noted in the three cases of a perfectly healthy person, a slightly ailing patient, and a really sick man.[727] In the last case one should further note their varying effects as the disease is marked by any excess of heat, cold, dryness, or moisture. Care should be taken that the simples themselves are pure and free from any admixture of a foreign substance.[728] “It is also essential to test the relation to the nature of the patient of all those things of which great use is made in the medical art.”[729] One condition to be observed in experimental investigation of critical days is to count no cases where any slip has been made by physician or patient or bystanders or where any other foreign factor has done harm.[730] Galen was acquainted with physical experiments in siphoning, for he says that, if one withdraws the air from a vessel containing sand and water, the sand will follow before the water, which is the heavier (sic?).[731]

Galen also points out some of the difficulties of medical experimentation. One is the extreme unlikelihood of ever being able to observe in even two cases the same combination of symptoms and circumstances.[732] The other is the danger to the life of the patient from rash experimenting.[733] Thus Galen more than once tells us of abstaining from testing some remedy because he had others of whose effects he was surer.

In the treatise on easily procurable remedies ascribed to Galen,[734] in which we have already seen evidence of later interpolation or authorship, some recipes are concluded by[Pg 162] such expressions as, “This has been experienced; it works unceasingly,”[735] or “Another remedy tested by us in many cases.”[736] This became a custom in many subsequent medical works, including those of the middle ages. One recipe is introduced by the caution, “But don’t cure anybody unless you have been paid first, for this has been tested in many cases.”[737] But we are left in some doubt whether we should infer that remedies tested by experience are so superior that they call for cash payment rather than credit, or so uncertain that it is advisable that the physician secure his fee before the outcome is known. In the middle ages the word experimentum was used a great deal as a synonym for any medical treatment, recipe, or prescription. Galen approaches this usage, which we have already noticed in Pliny’s Natural History, when he describes “a very important experiment” in bleeding performed by certain doctors at Rome.[738]

Indeed Galen appears to have exerted a great influence in the middle ages by his passages concerning experience in particular as well as by his medicine in general. Medieval writers cite him as an authority for the recognition of experience and reason as criteria of truth.[739] Gilbert of England cites “experiences from the book of experiments experienced by Galen,”[740] and we shall find more than one such apocryphal work ascribed to Galen in the middle ages. John of St. Amand seems to have developed seven rules[741] which he gives for discovering experimentally the properties of medicinal simples from what we have heard Galen say on the subject, and in another work, the Concordances, John collects a number of passages about experience from[Pg 163] the works of Galen.[742] Peter of Spain, who died as Pope John XXI in 1277, cites Galen in his discussion of “the way of experience” and “the way of reason” in his Commentaries on Isaac on Diets.[743] We have already suggested Galen’s possible influence upon Albertus Magnus, and we might add Roger Bacon who wrote some treatises on medicine. But it is hardly possible to tell whether such ideas were in the air, or were due to Galen individually either in their origin or their transmission. But he made a rather close approach to the medieval attitude in his equal regard for logic and for experimentation.

The more general influence of Galen upon all sides of the medicine of the following fifteen centuries has often been stated in sweeping terms, but is difficult to exaggerate. His general theories, his particular cures, his occasional marvelous stories, were often repeated or paraphrased. Oribasius has been called “the ape of Galen,” and we shall see that the epithet might with equal reason be applied to Aëtius of Amida. Indeed, as in the case of Pliny, we shall find plenty of instances of Galen’s influence in our later chapters. Perhaps as good a single instance of medieval study of Galen as could be given is from the Concordances of John of St. Amand already mentioned, which bear the alternative title, “Recalled to Mind” (Revocativum memoriae), since they were written to “relieve from toil and worry scholars who often spend sleepless nights in searching for points in the books of Galen.”[744] Or we may note how the associates of the twelfth century translator from the Arabic, Gerard of Cremona, added a list of his works at the close of his translation of Galen’s Tegni, “imitating Galen in the commemoration of his books at the end of the same treatise,” as they themselves state.[745]

Not that medieval men did not make additions of their[Pg 164] own to Galen. For instance, the noted Jewish philosopher, Moses Maimonides, in adding his collection of medical Aphorisms to the many previous compilations of this sort by Hippocrates, Rasis (Muhammad ibn Zakariya), Mesuë (Yuhanna ibn Masawaih), and others, states that he has drawn them mainly from the works of Galen, but that he supplements these with some in his own name and some by other “moderns.”[746] Not that Galen was not sometimes criticized or questioned. A later Greek writer, Symeon Seth, ventured to devote a special treatise to a refutation of some of Galen’s physiological views. In it, addressing himself to those “persons who regard you, O Galen, as a god,” he endeavored to make them realize that no human being is infallible.[747] Among the medical treatises of Gentile da Foligno, who was papal physician and performed a public dissection at Padua in 1341,[748] is found a brief argument against Galen’s fifth aphorism.[749] But such criticism or opposition[Pg 165] only shows how generally Galen was accepted as an authority.

From Galen’s habits of critical estimation rather than blind acceptation of authority, of scientific observation, careful measurement, and personal experiment, from his brilliant demonstrations by dissection, and his medical prognostication and therapeutics, sane and shrewd for his time,—from these we have now to turn to the other side of the picture, and examine what information his works afford us concerning the magic and astrology in ancient medicine, concerning the belief in occult virtues, suspensions, characters, incantations, and the like. We may first consider what he has to say concerning magic and divination as he understands those words, and then take up his attitude to those other matters which we look upon as almost equally deserving classification under those heads.

Apollonius of Tyana and Apuleius of Madaura were not the only celebrated men of learning in the early Roman Empire to be accused of magic; we have already alluded to the charges of magic made against Galen by the envious physicians of Rome during his first residence in that city. It is hard to escape the conviction that at that time learned men were very liable to be suspected or accused of magic. Indeed, Galen makes the general assertion that when a physician prognosticates aright concerning the future course of a malady, this seems so marvelous to most men that they would receive him with great affection, if they did not often regard him as a wizard.[750] Soon after saying this, Galen begins the story of the prognostications he made and the cure he wrought, when all the other doctors took an opposite view of the case.[751] One of them then jealously suggested that Galen’s diagnosis was due to divination.[752] When asked by what kind of divination, he gave different answers[Pg 166] at different times and to different persons, sometimes saying by dreams, sometimes by sacrificing, again by symbols, or by astrology. Afterwards such charges against Galen kept multiplying.[753] As a result, Galen says that since then he has not gone about advertising his prognostications like a herald, lest the physicians and philosophers hate him the more and slander him as a wizard and diviner, but that he now reveals his discoveries only to his friends.[754] In another treatise he represents Hippocrates as saying that a proficient doctor should be able to prognosticate the course of diseases, but adds that contemporary physicians call such a doctor a sorcerer and wonder-worker (γόητά τε καὶ παραδοξολόγον).[755] Again in his work on medicinal simples[756] he states that he abstained from testing the supposed virtue of crocodile’s blood in sharpening the vision, and the blood of house mice in removing warts, partly because he had other reliable eye-medicines and cures for warts—such as myrmecia, a gem with wart-like lumps, partly because by employing such substances he feared to incur the reputation of a sorcerer, since jealous physicians were already slandering his medical prognostications as divination. This last passage affords a good illustration of the close connection with magic of certain natural substances supposed to possess marvelous virtues, while Galen’s wart stone also seems magical to the modern reader.

Galen himself sometimes calls other physicians magicians. Certain men with whom he does not agree are called by him “liars or wizards or I don’t know what to say,”[757] and another man who used mouse dung to excess he calls superstitious and a sorcerer.[758] In the same work on simples[759] he says that he will list herbs in alphabetical order as Pamphilus did, but that he will not like him descend to old wives’ tales, Egyptian sorceries and incantations, amulets and other magical devices, which not only do not belong in the medical art[Pg 167] but are utterly false. Pamphilus never saw most of the herbs he mentioned, much less tested their virtues, but copied anything he found, piling up names, incantations, and wizardry. Galen accuses Xenocrates Aphrodisiensis also of not having eschewed sorcery, and he notes that medical writers have either said nothing about sweat or what is superstitious and bordering upon magic.[760]

Philters, love-charms, dream-draughts, and imprecations Galen regards as impossible or injurious, and intends to have nothing to do with them. He thinks it ridiculous to believe that by such spells one can bewitch one’s adversaries so that they cannot plead in court, or conceive or bear children. He considers it worse to advertise and perpetuate such false or criminal notions in writings than to practice such a crime but once.[761] In one passage,[762] however, to illustrate his theory that the gods prepare the sperms of plants and animals, and set them going as it were, and afterwards leave them to themselves, Galen compares them to the wonder-workers—who were perhaps not magicians but men similar to our sidewalk fakirs who exhibit mechanical toys—who start things moving and then go away themselves while what they have prepared moves on artificially for a time.

Galen’s own works are not entirely free from the magical devices of which he accuses others. We may begin with animal substances, since he himself has testified that the use of sweat, crocodile’s blood, and mouse’s dung is suggestive of magic. Moreover, he attributes more bizarre virtues to the parts of animals than to herbs or stones. In a passage somewhat similar to that in which Pliny[763] expressed his horror at the use of human blood, entrails, and skulls as medicines, Galen declares that he will not mention the abominable and detestable, as Xenocrates and some others have done. The Roman law has long forbidden eating human flesh, while Galen regards even the mention of certain secretions and excrements of the human body as[Pg 168] offensive to modest ears.[764] Nevertheless, before long he offends against his own standard and describes how he administered to patients the very substance which he had before characterized as most unmentionable.[765] It may also be noted that he repeats unquestioningly such a tale as that the cubs of the bear are born unformed and licked into shape by their mother.[766]

Further milder illustrations of the fact that such nasty substances were then not merely recommended in books but freely employed in actual medical practice, are seen in the frequent use by one of Galen’s teachers of the dung of dogs who for two days before had eaten nothing but bones,[767] in Galen’s own wonderfully successful treatment of a tumor on a rustic’s knee with goat dung—which is, however, too sharp for the skins of children or city ladies,[768] and in his discovery by repeated experience that the dung of doves who take little exercise is less potent than that of those who take much,[769] Galen also says that he has known of doctors who have cured many persons by giving them burnt human bones in drink without their knowledge.[770]

Galen’s medicinal simples include the bile of bulls, hyenas, cocks, partridges, and other animals.[771] A digestive oil can be manufactured by cooking foxes and hyenas, some alive and some dead, whole in oil.[772] Galen discusses with perfect seriousness the relative strength of various animal fats, those of the goose, hen, hyena, goat, pig, and so forth.[773] He decides that lion’s fat is by far the most potent, with that of the pard next. Among his simples are also found the slough of a snake, a sheepskin, the lichens of horses, a spider’s web,[774] and burnt young swallows, for whose introduction into medicine he gives Asclepiades credit.[775] Of[Pg 169] Archigenes’ prescriptions for toothache he repeats that which recommended holding for some time in the mouth a frog boiled in water and vinegar, or a dog’s tooth, burnt, pulverized, and boiled in vinegar.[776] Cavities may be filled with toasted earthworms or spiders’ eggs diluted with unguent of nard. Teething infants are benefited, if their gums are moistened with dog’s milk or anointed with hare’s brains.[777] For colic he recommends dried cicadas with three, five, or seven grains of pepper.[778]

Galen is less confident as to the efficacy for earache of the multipedes which roll themselves up into a ball, and which, cooked in oil, are employed especially by rural doctors.[779] He is still more sceptical whether the liver of a mad dog will cure its bite.[780] Many say so, and he knows of some who have tried it and survived, but they took other remedies too.[781] Galen has heard that some who trusted to it alone died. In one treatise[782] Galen discusses the strange virtues of the basilisk in much the usual way, but in his work on simples[783] he remarks drily that it is obviously impossible to employ it in pharmacy, since, if the tales about it be true, men cannot see it and live or even approach it without danger. He therefore will not include it or elephants or Nile horses (hippopotamuses?) or any other animals of which he has had no personal experience.

Galen tries to find some satisfactory explanation of the strange properties which he believes exist in so many things. The attractive power of the magnet and of drugs suggests to him that nature in us is divine, as Homer says, and leads like to like and thus shows its divine virtues.[784] Galen rejects Epicurus’s explanation of the magnet’s attractive power.[785] It was that the atoms flowing off from both the magnet and iron fit one another so closely that the two sub[Pg 170]stances are drawn together. Galen objects that this does not explain how a whole series of rings can be suspended in a row from a magnet. Galen’s teacher Pelops, who claimed to be able to tell the cause of everything, explained why ashes of river crabs are used for the bite of a mad dog as follows.[786] The crab is efficacious against hydrophobia because it is an aquatic animal. River crabs are better for this purpose than salt water crabs because salt dries up moisture. He also thought the ashes of crabs very potent in absorbing the venom. But this type of reasoning is unsatisfactory to Galen, who finds the best explanation of all such action in the peculiar property, or occult virtue, of the substance as a whole. Upon this subject[787] he proposes to write a separate treatise, and in the fragment De substantia facultatum naturalium (περὶ οὐσίας τῶν φυσικῶν δυνάμεων) he again discusses the matter.[788]

Among parts of animals Galen regarded the flesh of vipers as especially medicinal, particularly as an antidote to poisons. Of the following cures wrought by vipers’ flesh which Galen narrates[789] two were repeated without giving him credit by Aëtius of Amida in the sixth, and Bartholomew of England in the thirteenth century, and doubtless by other writers. When Galen was a youth in Asia, some reapers found a dead viper in their jug of wine and so were afraid to drink any of it. Instead they gave it to a man near by who suffered from the terrible skin disease elephantiasis and whom they thought it would be a mercy to put quietly out of his misery. He drank the wine but instead of dying recovered from his disease. A similarly unexpected cure was effected when a slave wife in Mysia tried to kill her hus[Pg 171]band by offering him a like drink. A third case was that of a patient whom Galen told of these two previous cures. After resorting to augury to learn if he too should try it and receiving a favorable response, the patient drank wine infected by venom with the result that his elephantiasis changed into leprosy, which Galen cured a little later with the usual drugs. A fourth man, while hunting vipers, was stung by one. Galen bled him, extracted black bile with a drug, and then made him eat the vipers which he had caught and which were prepared in oil like eels. A fifth man, warned by a dream, came from Thrace to Pergamum. Another dream instructed him both to drink, and to anoint himself with, a concoction of vipers. This changed his disease into leprosy which in its turn was cured by drugs which the god prescribed.

The flesh of vipers was an important ingredient in the famous antidote and remedy called theriac, concerning which Galen wrote two special treatises[790] besides discussing it in his works on simples and antidotes. Mithridates, like King Attalus in Galen’s native land, had tested the effects of various drugs upon condemned criminals, and had thus discovered antidotes against spiders, scorpions, sea-hares, aconite, and other poisons. He then combined the results of his research into one grand compound which should be an antidote against any and every poison. But he did not include the flesh of the viper, which was added with some other changes by Andromachus, chief physician to Nero.[791] The divine Marcus Aurelius used to take a dose of theriac daily and it had since come into general use.[792] Galen gives a long list of ills which it will cure, including the plague and hydrophobia,[793] and adds that it is beneficial in keeping a man in good health.[794] He advises its use when traveling or in wintry weather, and tells Piso that it will prolong his life.[795] He explains more than once[796] how to prepare the[Pg 172] viper’s flesh, why the head and tail must be cut off, how it is cleaned and boiled until the flesh falls from the backbone, how it is mixed with pounded bread into pills, how the flesh of the viper is best in early summer. Galen also accepts the legend,[797] quoting six lines of verse from Nicander to that effect, that the viper conceives in the mouth and then bites off the male’s head, and that the young viper avenges its father’s death by gnawing its way out of its mother’s vitals. The Marsi at Rome denied the existence of the dipsas or snake whose bite causes one to die of thirst, but Galen is not quite sure whether to agree with them.

Already we have had occasion to refer to Galen’s two works on compound medicines which occupy the better part of two bulky volumes in Kühn’s edition and contain a vast number of prescriptions. It is not uncommon for one of these to contain as many as twenty-five ingredients. It seems unlikely that such elaborate concoctions would have been discovered by chance, as the Empirics held, but the modern reader is ready to agree that it was chance, if anyone was ever cured of anything by one of them. Yet Galen, as we have seen, believes that reasons can be given for the ingredients and would not for a moment admit that they are no better than the messes of witches’ cauldrons. He argues that, if all diseases could be cured by simples, no one would use compounds, but that they are essential for some diseases, especially such as require the simultaneous application of contrary virtues.[798] Also where a simple is too strong or weak, it can be toned up or down to just the right strength in a compound. Plasters and poultices seem always to be compounds. Of panaceas Galen is somewhat more chary, except in the case of theriac; he opines that a medicine which is good for a number of ills cannot be very good for any one of them.[799]

Procedure as well as substances suggestive of magic is found to some extent in Galen’s works. He instructs, for[Pg 173] example, to pluck an herb with the left hand before sunrise.[800] He also recommends the suspension of a peony to cure epilepsy.[801] He saw a boy who wore this root remain free from that disease for eight months, when the root happened to drop off and the boy soon fell in a fit. When another peony root was hung about his neck, he remained in good health until Galen for the sake of experiment removed it a second time, whereupon another epileptic fit ensued as before. In this case Galen suggests that perhaps some particles from the root were drawn in by the patient’s breathing or altered the surrounding air. In another passage he holds that there is no medical reason to account for the virtues of amulets, but that those who have tested them by experience say that they act by some marvelous antipathy unknown to man.[802] A ligature recommended by Galen is to bind about the neck of the patient a viper which has been suffocated by tying several strings, preferably of marine purple, about its neck.[803] Galen marvels that stercus lupinum, even when simply suspended from the neck, “sometimes evidently is beneficial.”[804] It should not have touched the ground but should have been taken from trees or bushes. It also works better, as Galen has found in his own practice, if suspended by the wool of a sheep who has been torn by a wolf.

While Galen thus employs ligatures and suspensions and sanctions magic logic, he draws the line at use of images, characters, and incantations. In the passage just cited he goes on to say that he has found other suspended substances efficacious, but not the barbarous names such as wizards use. Some say that the gem jasper comforts the stomach if bound about the abdomen,[805] and some wear it in a ring engraved with a dragon and rays,[806] as King Nechepso directs in his fourteenth book. Galen has employed it suspended about the neck without any engraving upon it and[Pg 174] found it equally beneficial. In illustrating the virtue of human saliva, especially that of a fasting man, Galen tells of a man who promised him to kill a scorpion by means of an incantation which he repeated thrice. But at each repetition he spat on the scorpion and Galen afterwards killed one by the same procedure without any incantation, and more quickly with the spittle of a fasting than of a full man.[807]

The preceding paragraph gives a good illustration of the slow progress of human thought away from magic and towards science. Men are discovering that marvels can be worked as well without characters and incantations. Similar passages may be found in Arabic and Latin medieval writers. But while Galen questions images and incantations, he still clings to the notions of marvelous virtue in a fasting man’s spittle or in a gem suspended about the neck. And these and other passages in which he clung to old superstitions were unfortunately equally influential upon succeeding writers, who sometimes, we fear, took them as an excuse for further indulgence in magic. Indeed, we shall find Alexander of Tralles in the sixth century arguing that Galen finally became a believer in the efficacy of incantations. Thus the old notions and practices die hard.

In the treatise on easily procurable remedies, where popular and rustic remedies enter rather more largely than in Galen’s other writings, superstitious recipes are also met with more frequently, and, if that be possible, the doses become even more calculated to make one’s gorge rise, it being felt that the unfastidious tastes and crude constitutions of peasants and the poorer classes can stand more than daintier city patients. Another reason for separate consideration of the contents of this treatise is the possibility, already mentioned, that it is interpolated and misarranged, and the fact that it is in part of much later date than Galen.

[Pg 175]

We must limit ourselves to a hasty survey of a few specimens of its prescriptions. Following Archigenes, ligatures and crowns are employed for headaches.[808] In contrast to Galen’s previous scepticism concerning depilatories for eyebrows we now find a number mentioned, including the blood of a bed-bug.[809] To cure lumbago,[810] if the pain is in the right foot, reduce to powder with your right hand the wings of a swallow. Then make an incision in the swallow’s leg and draw off all its blood. Skin it and roast it and eat it entire. Then anoint yourself all over with the oil for three days and you will marvel at the result. “This has been often proved by experience.” To prevent hair from falling out take many bees and burn them and mix with oil and use as an ointment.[811] For a sty in the eye catch flies, cut off their heads, and rub the sty with the rest of their bodies.[812] A cooked black chameleon performs the double duty of curing toothache and killing mice.[813] To extract a tooth in the upper jaw surround it with the worms found in the tops of cabbages; for a lower tooth use the worms on the lower parts of the leaves.[814] Pain in the intestines will vanish, if the patient drinks water in which his feet have been washed.[815] A net transferred from a woman’s hair to the patient’s head acts as a laxative, especially if the net is first heated.[816] Various superstitious devices are suggested to insure the birth of a child of the sex desired.[817] Bituminous trefoil,[818] boiled and applied hot, cures snake or spider bite, but let no one use it who is not so afflicted or it will make him feel as if he was.[819] For cataract is recommended a mixture of equal parts of mouse’s blood, cock’s gall, and woman’s milk,[Pg 176] dried.[820] For pain on one side of the head or face smear with fifteen earthworms and fifteen grains of pepper powdered in vinegar.[821] To stop a cough wear the tongue of an eagle as an amulet.[822] Wearing a root of rhododendron makes one fearless of dogs and would cure a mad dog itself, if it could be tied on the animal.[823] A “confection” covering three pages is said to prolong life, to have been used by the emperors, and to have enabled Pythagoras, its inventor, who began to make use of it at the age of fifty, to live to be one hundred and seventeen without disease. “And he was a philosopher and unable to lie about it.”[824]

It remains to note what there is in Galen’s works in the way of divination and astrology. We are not entirely surprised that contemporary doctors confused his medical prognostic with divination, when we read what he has to say concerning the outward signs of hot or cold internal organs. In the treatise, entitled The Healing Art (τέχνη ἰατρική),[825] which Mewaldt says was the most studied of Galen’s works and spread in a vast number of medieval Latin manuscript translations,[826] he devotes a number of chapters to such subjects as signs of a hot and dry heart, signs of a hot liver, and signs of a cold lung. Among the signs of a cold brain are excessive excrements from the head, stiff straight red hair, a late birth, mal-nutrition, susceptibility to injury from cold causes and to catarrh, and somnolence.[827]

In his commentary on the Aphorisms of Hippocrates Galen adds other signs by which it may be foretold whether the child will be a boy or girl to those signs already mentioned by Hippocrates.[828] Some of these seem superstitious enough to us. And it was a case of the evil that men do living after them, for Moses Maimonides, the noted Jewish physician of Cordova in the twelfth century, in his collection[Pg 177] of Aphorisms, drawn chiefly from the works of Galen, repeats the following method of prognostication: Puerum cum primo spermatizat perscrutare, quem si invenis habere testiculum dextrum maiorem sinistro, you will know that his first child will be a male, otherwise female. The same may be determined in the case of a girl by a comparison of the size of her breasts. Maimonides also repeats, from Galen’s work to Caesar on theriac,[829] the story of the ugly man who secured a beautiful son by having a beautiful boy painted on the wall and making his wife keep her eyes fixed upon it. Maimonides also repeats from Galen[830] the story of the bear’s licking its unformed cubs into shape.[831]

In another treatise on Diagnosis from Dreams Galen makes a closer approach to the arts of divination.[832] He states that dreams are affected by our daily life and thought, and describes a few corresponding to bodily states or caused by them. He thinks that if you dream you see fire, you are troubled by yellow bile, and if you dream of vapor or darkness, by black bile. In diagnosing dreams one should note when they occurred and what had been eaten. But Galen also believes that to some extent the future can be predicted from dreams, as has been testified, he says, by experience.[833] We have already mentioned the effect of his father’s dream upon Galen’s career. In the Hippocratic commentaries[834] he says that some scorn dreams and omens and signs, but that he has often learned from dreams how to prognosticate or cure diseases. Once a dream instructed him to let blood between the index and great fingers of the right hand until the flow of blood stopped of its own accord. “It is necessary,” he concludes, “to observe dreams accurately both as to what is seen and what is done in sleep in order that you[Pg 178] may prognosticate and heal satisfactorily.” Perhaps he had a dim idea along Freudian lines.

In the ordinary run of Galen’s pharmacy and therapeutics there is very little mention or observance of astrological conditions, although Hippocrates is cited as having said that a study of geometry and astronomy—which may well mean astrology—is essential in medicine.[835] In the De methodo medendi he often urges the importance of the time of year, the region, and the state of the sky.[836] But this expression seems to refer to the weather rather than to the position of the constellations. The dog-star is also occasionally mentioned,[837] and one passage[838] tells how “Aeschrion the Empiric, ... an old man most experienced in drugs and our fellow citizen and teacher,” burned live river crabs on a plate of red bronze after the rise of the dog-star when the sun entered Leo and on the eighteenth day of the moon. We are also informed that many Romans are in the habit of taking theriac on the first or fourth day of the moon.[839] But Galen ridicules Pamphilus for his thirty-six sacred herbs of the horoscope—or decans, taken from an Egyptian Hermes book.[840] On the other hand, one of his objections to the atomists is that “they despise augury, dreams, portents, and all astrology,” as well as that they deny a divine artificer of the world and an innate moral law to the soul.[841] Thus atheism and disbelief in astrology are put on much the same plane.

Whereas there is so little to suggest a belief in astrology in most of Galen’s works, we find among them two devoted especially to astrological medicine, namely, a treatise on critical days in which the influence of the moon upon disease is assumed, and the Prognostication of Disease by Astrology. In the latter he states that the Stoics favored astrology, that Diodes Carystius represented the ancients[Pg 179] as employing the course of the moon in prognostications, and that, if Hippocrates said that physicians should know physiognomy, they ought much more to learn astrology, of which physiognomy is but a part.[842] There follows a statement of the influence of the moon in each sign of the zodiac and in its relations to the other planets.[843] On this basis is foretold what diseases a man will have, what medical treatment to apply, whether the patient will die or not, and if so in how many days. This treatise is the same as that ascribed in many medieval manuscripts to Hippocrates and translated into Latin by both William of Moerbeke and Peter of Abano.

The treatise on critical days discusses them not by reason or dogma, lest sophists befog the plain facts, but solely, we are told, upon the basis of clear experience.[844] Having premised that “we receive the force of all the stars above,”[845] the author presents indications of the especially great influence of sun and moon. The latter he regards not as superior to the other planets in power, but as especially governing the earth because of its nearness.[846] He then discusses the moon’s phases, holding that it causes great changes in the air, rules conceptions and birth, and “all beginnings of actions.”[847] Its relations to the other planets and to the signs of the zodiac are also considered and much astrological technical detail is introduced.[848] But the Pythagorean theory that the numbers of the critical days are themselves the cause of their significance in medicine is ridiculed, as is the doctrine that odd numbers are masculine and even numbers feminine.[849] Later the author also ridicules those who talk of seven Pleiades and seven stars in either Bear and the seven gates of Thebes or seven mouths of the Nile.[850] Thus he will not accept the doctrine of perfect or magic numbers along with his astrological theory. Much of this rather[Pg 180] long treatise is devoted to a discussion of the duration of a moon, and it is shown that one of the moon’s quarters is not exactly seven days in length and that the fractions affect the incidence of the critical days.

A treatise on the history of philosophy, which is marked “spurious” in Kühn’s edition, I have also discovered among the essays of Plutarch where, too, it is classed as spurious.[851] In some ways it is suggestive of the middle ages. After an account of the history of Greek philosophy somewhat in the style of the brief reviews of the same to be found in the church fathers, it adds a sketch of the universe and natural phenomena not dissimilar to some medieval treatises of like scope. There are chapters on the universe, God, the sky, the stars, the sun, the moon, the magnus annus, the earth, the sea, the Nile, the senses, vision and mirrors, hearing, smell and taste, the voice, the soul, breathing, the processes of generation, and so on.

In discussing divination[852] the treatise states that Plato and the Stoics attributed it to God and to divinity of the spirit in ecstasy, or to interpretation of dreams or astrology or augury. Xenophanes and Epicurus denied it entirely. Pythagoras admitted only divination by haruspices or by sacrifice. Aristotle and Dicaearchus admit only divination by enthusiasm and by dreams. For although they deny that the human soul is immortal, they think that there is something divine about it. Herophilus said that dreams sent by God must come true. Other dreams are natural, when the mind forms images of things useful to it or about to happen to it. Still others are fortuitous or mere reflections of our desires. The treatise also takes up the subject of heroes and demons.[853] Epicurus denied the existence of[Pg 181] either, but Thales, Plato, Pythagoras, and the Stoics agree that demons are natural substances, while heroes are souls separate from bodies, and are good or bad according to the lives of the men who lived in those bodies.

The treatise also gives the opinions of various Greek philosophers on the question whether the universe or its component spheres are either animals or animated. Fate is defined on the authority of Heracleitus as “the heavenly body, the seed of the genesis of all things.”[854] The question is asked why babies born after seven months live, while those born after eight months die.[855] On the other hand, a very brief discussion of how the stars prognosticate does not go into particulars beyond their indication of seasons and weather, and even this Anaximenes ascribed to the effect of the sun alone.[856] Philolaus the Pythagorean is quoted concerning some lunar water about the stars[857] which reminds one of the waters above the firmament in the first chapter of Genesis.

“doctum ex omnibus solum neque in alienis locis peregrinum ... sed in omni civitate esse civem.”

—Vitruvius, VI, Introd. 2.

This chapter will examine what may be called ancient applied science and its relations to magic, taking observations at three different points, the ten books of Vitruvius on architecture, the collection of writings which pass under the name of Hero of Alexandria, and the compositions of the Greek alchemists. The remains of Greek and Roman literature in the field of applied science are scanty, not because they were not treasured, and even added to, by the periods following, but apparently because there had thus far been so little development in the way of machinery or of power other than manual and animal. So we must make the best of what we have. The writings to be considered are none of them earlier than the period of the Roman Empire but[Pg 183] like other writings of that time they more or less reflect the scientific achievements or the occult lore of the preceding Hellenistic period.

Vitruvius lived just at the beginning of the Empire under Julius and Augustus Caesar. He is not much of a writer, but architecture as set forth in his book appears sane, straightforward, and solid. The architect is represented as going about his business with scarcely any admixture of magical procedure or striving after marvelous results. The combined guidance of practical utility and of high standards of art—Vitruvius stresses reality and propriety now and again, and has little patience with mere show—perhaps accounts for this high degree of freedom from superstition. Perhaps permanent building is an honest, downright, open, constructive art where error is at once apparent and superstition finds little hold. If so, one wonders how there came to be so much mystery enveloping Free-Masonry. At any rate, not only in his building directions, but even in his instructions for the preparation of lime, stucco, and bricks, or his discussion of colors, natural and artificial, Vitruvius seldom or never embodies anything that can be called magical.[858]

This is the more noteworthy because passages in the very same work show him to have accepted some of the theories which we have associated with magic. Thus he appears to believe in occult virtues and marvelous properties of things in nature, since he affirms that, while Africa in general abounds in serpents, no snake can live within the boundaries of the African city of Ismuc, and that this is a property of the soil of that locality which it retains when exported.[859] Vitruvius also mentions some marvelous waters. One[Pg 184] breaks every metallic receptacle and can be retained only in a mule’s hoof. Some springs intoxicate; others take away the taste for wine. Others produce fine singing voices.[860] Vitruvius furthermore speaks of six and ten as perfect numbers and contends that the human body is symmetrical in the sense that the distances between the different parts are exact fractions of the whole.[861] He also tells how the Pythagoreans composed books on the analogy of the cube, allowing in any one treatise no more than three books of 216 lines each.[862]

Vitruvius also more than once implies his confidence in the art of astrology. In mapping out the ground-plan of his theater he advises inscribing four equilateral triangles within the circumference of a circle, “as the astrologers do in a figure of the twelve signs of the zodiac, when they are making computations from the musical harmony of the stars.”[863] I cannot make out that there is any astrological significance or magical virtue in this so far as the arrangement of the theater is concerned, but it shows that Vitruvius and his readers are familiar with the technique of astrology and the trigona of the signs. In another passage, comparing the physical characteristics and temperaments of northern and southern races, which astrologers generally interpreted as evidence of the influence of the constellations upon mankind, Vitruvius patriotically contends that the inhabitants of Italy, and especially the Romans, represent a happy medium between north and south, combining the greater courage of the northerners with the keener intellects of the southerners, just as the planet Jupiter is a golden mean between the extreme influences of Mars and Saturn. So the Romans are fitted for world rule, overcoming barbarian valor by their superior intelligence and the devices of the southerners by their valor.[864] In a third passage Vitruvius says more expressly of the art of astrology: “As for the branch of[Pg 185] astronomy which concerns the influences of the twelve signs, the five stars, the sun, and the moon upon human life, we must leave all this to the calculations of the Chaldeans, to whom belongs the art of casting nativities, which enables them to declare the past and the future by means of calculations based on the stars. These discoveries have been transmitted by men of genius and great acuteness who sprang directly from the nations of the Chaldeans; first of all, by Berosus, who settled in the island state of Cos, and there opened a school. Afterwards Antipater pursued the subject; then there was Archinapolus, who also left rules for casting nativities, based not on the moment of birth but on that of conception.” After listing a number of natural philosophers and other astronomers and astrologers, Vitruvius concludes: “Their learning deserves the admiration of mankind; for they were so solicitous as even to be able to predict, long beforehand, with divining mind, the signs of the weather which was to follow in the future.”[865]

Such a passage demonstrates plainly enough Vitruvius’ full confidence in the art of casting nativities and of weather prediction, but it has no integral connection with his practical architecture or even any necessary connection with the construction of a sun-dial, which is what he is actually driving at. But Vitruvius believed that an architect should not be a mere craftsman but broadly educated in history, medicine, and philosophy, geometry, music, and astronomy, in order to understand the origin and significance of details inherited from the art of the past, to assure a healthy building, proper acoustics, and the like. It is in an attempt to air his learning and in the theoretical portions of his work that he is prone to occult science. But the practical processes of architecture and military engineering are free from it.

The attitude of Vitruvius towards other architects of his own age, to past authorities, and to personal experimentation is of interest to note, and roughly parallels the attitude of Galen in the field of medicine. Like Galen he com[Pg 186]plains that the artist must plunge into the social life of the day in order to gain professional success and recognition.[866] “And since I observe that the unlearned rather than the learned are held in high favor, deeming it beneath me to struggle for honors with the unlearned, I will rather demonstrate the virtue of our science by this publication.”[867] He also objects to the self-assertion and advertising of themselves in which many architects of his time indulge.[868] He recognizes, however, that the state of affairs was much the same in time past, since he tells a story how the Macedonian architect, Dinocrates, forced himself upon the attention of Alexander the Great solely by his handsome and stately appearance,[869] and since he asserts that the most famous artists of the past owe their celebrity to their good fortune in working for great states or men, while other artists of equal merit are seldom heard of.[870] He also speaks of those who plagiarize the writings of others, especially of the men of the past.[871] But all this does not lead him to despair of art and learning; rather it confirms him in the conviction that they alone are really worth while, and he quotes several philosophers to that effect, including the saying of Theophrastus that “the learned man alone of all others is no stranger even in foreign lands ... but is a citizen in every city.”[872]

In contradistinction to the plagiarists Vitruvius expresses his deep gratitude to the men of the past who have written books, and gives lists of his authorities,[873] and declares that “the opinions of learned authors ... gain strength as time[Pg 187] goes on.”[874] “Relying upon such authorities, we venture to produce new systems of instruction.”[875] Or, as he says in discussing the properties of waters, “Some of these things I have seen for myself, others I have found written in Greek books.”[876] But in describing sun-dials he frankly remarks, “I will state by whom the different classes and designs of dials have been invented. For I cannot invent new kinds myself at this late day, nor do I think that I ought to display the inventions of others as my own.”[877] He also gives an account of a number of notable miscellaneous discoveries and experiments by past mathematicians and physicists.[878] Also he sometimes repeats the instruction which he had received from his teachers. Like Pliny a little later he thinks that in some respects artistic standards have been lowered in his own time, notably in fresco-painting.[879] But also, like Galen, he once admits that there are still good men in his own profession besides himself, affirming that “our architects in the old days, and a good many even in our own times, have been as great as those of the Greeks.”[880] He describes a basilica which he himself had built at Fano.[881]

Vitruvius’s last book is devoted to machines and military engines. Here he makes a feeble effort to introduce the factor of astrological influence, asserting that “all machinery is derived from nature, and is founded on the teaching and instruction of the revolution of the firmament.”[882] Among the devices described is the pump of Ctesibius of Alexandria, the son of a barber.[883] He had already been mentioned in the preceding book[884] for the improvements which he introduced in water-clocks, especially regulating their flow according to the changing length of the hours of the day in summer and winter. Vitruvius also asserts that he constructed the first water organs, that he “discovered[Pg 188] the natural pressure of the air and pneumatic principles, ... devised methods of raising water, automatic contrivances, and amusing things of many kinds, ... blackbirds singing by means of waterworks, and angobatae, and figures that drink and move, and other things that have been found to be pleasing to the eye and the ear.”[885] Vitruvius states that of these he has selected those that seemed most useful and necessary and that the reader may turn to Ctesibius’s own works for those which are merely amusing. Pliny more briefly mentions the invention of pneumatics and water organs by Ctesibius.[886]

This characterization by Vitruvius of the writings of Ctesibius also applies with astonishing fitness to some of the works current under the name of Hero of Alexandria,[887] who is indeed in a Vienna manuscript of the Belopoiika spoken of as the disciple or follower of Ctesibius.[888] Hero, however, is not mentioned either by Vitruvius or Pliny, and it is now generally agreed as a result of recent studies that he belongs to the second century of our era.[889] His writings are objective and impersonal and tell us much less about himself than Vitruvius’s introductions to the ten books of De architectura.[Pg 189] The similarity in content of his writings to those of the much earlier Ctesibius as well as the character of his terminology suggest that he stands at the end of a long development. He speaks of his own discoveries, but perhaps in the main simply continues and works over the previous principles and mechanisms of men like Ctesibius. As things stand, however, his works constitute our most important, and often our only, source for the history of exact science and of technology in antiquity.[890]

Not only does Hero seem to have been in large measure a compiler and continuer of previous science, his works also have evidently been worked over and added to in subsequent periods and bear marks of the Byzantine, Arabian, and medieval Latin periods as well as of the Hellenistic and Roman. Indeed Heiberg regards the Geometry and De stereometricis and De mensuris as later Byzantine collections which have perhaps made some use of the works of Hero, while the De geodaesia is an epitome of, or extract from, a pseudo-Heronic collection. The Catoptrica is known only from the Latin translation of 1269, probably by William of Moerbeke, and long known as Ptolemy on Mirrors. It appears, however, to be directly translated from the Greek and not from the Arabic. The Mechanics, on the other hand, is known only from the Arabic translation by Costa ben Luca. Of the Pneumatics we have Greek, Arabic, and Latin versions. It was apparently known to the author of the thirteenth century Summa philosophiae ascribed to Robert Grosseteste, since he speaks of the investigations of vacuums made by “Hero, that eminent philosopher, with the aid of water-clocks, siphons, and other instruments.”[891] Scholars are of the opinion that the Arabic adaptation, which is of popular character and limited to the entertaining side, comes closer to the original Greek version of Hero’s time than does the Latin version which devotes more attention to experimental physics. The Automatic Theater, for which there is the same[Pg 190] chief manuscript as for the Pneumatics, also seems to have been worked over and added to a great deal.

From Vitruvius’s allusions to the works of Ctesibius and from a survey of those works current under Hero’s name which are chiefly concerned with mechanical contrivances and devices, the modern reader gets the impression that, aside from military engines and lifting appliances, the science of antiquity was applied largely to purposes of entertainment rather than practical usefulness. However, in Hero’s case at least there is something more than this. His apparatus and experiments are not intended so much to divert as to deceive the spectator, and not so much to amuse as to astound him. The mechanism is usually concealed; the cause acts indirectly, intermediately, or from a distance to produce an apparently marvelous result. It is a case of thaumaturgy, as Hero himself says,[892] of apparent magic. In fine, the experimental and applied scientist is largely interested in vying with the feats of the magicians or supplying the temples and altars of religion with pseudo-miracles.

The introduction or proemium to the Pneumatics is rather more truly scientific and has been called an unusual instance in antiquity of the use as proof of purposive observation of nature and experiment. Thus the existence of air is demonstrated by the experiment of pressing an inverted vessel, kept carefully upright, into water, which will not enter the vessel because of the resistance offered by the air already within the vessel. Or the elasticity of air and the existence of empty spaces between its particles is shown by the experiment of blowing more air into a globe through a siphon, and then holding one’s finger over the orifice. As soon as the finger is removed the surplus air rushes out with a loud report. Along with such admirable experimental proof, however, the introduction contains some astonishingly erroneous assertions, such as that “slime and mud are transformations of water into earth,” and that air released from[Pg 191] a vessel under water “is transformed so as to become water.” Hero believes that heat and light rays are particles of matter which penetrate the interstices between the particles composing air and water.

The Pneumatics consist of some seventy-eight theorems or experiments or tricks, call them what you will, which in different manuscripts and editions are variously grouped in a single book or two books. The same idea or method, however, is often repeated in the different chapters. Thus we encounter over half a dozen times the magic water-jar or drinking horn from which either wine or water or a mixture of both can be poured, or a choice of other liquids. And in all these cases the explanation of the trick is the same. When the air-hole in the top of the vessel is closed so that no air can enter, the liquid will not flow out through the narrow orifice in the bottom. Changes are rung on this principle by means of inner compartments and connecting tubes. Different kinds of siphons, the bent, the enclosed, and the uniform discharge, are described in the opening chapters and are utilized in working the ensuing wonders, such as statues of animals which drink water offered to them, inexhaustible goblets or those that will not overflow, and harmonious jars. By this last expression is meant pairs of vessels, secretly connected by tubes and so arranged that nothing will flow from one until the other is filled, when wine will pour from one jar and water from the other. Or when water is poured into one jar, wine or mixed wine and water flows from the other. Or, when water is drawn off from one jar, wine flows from the other. Other vessels are made to commence or cease to pour out wine or water, when a little water is poured in. Others will receive no more water once you have ceased pouring it in, no matter how little may have been poured in, or, when you cease for a moment to pour water in and then begin again, will not resume their outpour until half full. In another case the water will not flow out of a hole in the bottom of the vessel at all until the vessel is entirely filled. Others are made[Pg 192] to flow by dropping a coin in a slot or working a lever, or turning a wheel. In the last case the vessel of water is concealed behind the entrance column of a temple. In one magic drinking horn the flow of water from the bottom is checked by putting a cover over the open top. When another pitcher is tipped up, the same amount of liquid will always flow out.

In half a dozen chapters mechanical birds are made to sing by driving air through a pipe by the pressure of flowing water. In other chapters a dragon is made to hiss and a thyrsus to whistle by similar methods. By the force of compressed air water is made to spurt forth and automatons to sound trumpets. The heat of the sun’s rays is used to warm air which expands and causes water to trickle out. In a number of cases as long as a fire burns on an altar the expansion of enclosed air caused thereby opens temple doors by the aid of pulleys, or causes statues to pour libations, dancing figures to revolve, and a serpent to hiss. The force of steam is used to support a ball in mid-air, revolve a sphere, and make a bird sing or a statue blow a horn. Inexhaustible lamps are described as well as inexhaustible goblets, and a self-trimmed lamp in which a float resting on the oil turns a cog-wheel which pushes up the wick as it and the oil are consumed. Floats and cog-wheels are also used in some of the tricks already mentioned. In another the flow of a liquid from a vessel is regulated by a float and a lever. Cog-wheels are also employed in constructing the neck of an automaton so that it can be cut completely through with a knife and yet the head not be severed from the body. A cupping glass, a syringe, a fire engine pump with valves and pistons, a hydraulic organ and one worked by wind pretty much exhaust the contents of the Pneumatics. In its introduction Hero alludes to his treatise in four books on water-clocks, but this is not extant. Hero’s water-organ is regarded as more primitive than that described by Vitruvius.[893]

If magic jugs and marvelous automatons make up most of the contents of the Pneumatics and Automatic Theater,[Pg 193] comic and magic mirrors play a prominent part in the Catoptrics. The spectator sees himself upside down, with three eyes, two noses, or an otherwise distorted countenance. By means of two rectangular mirrors which open and close on a common axis Pallas is made to spring from the head of Zeus. Instructions are given how to place mirrors so that the person approaching will see no reflection of himself but only whatever apparition you select for him to see. Thus a divinity can be made suddenly to appear in a temple. Clocks are also described where figures appear to announce the hours.

Hero displays a slight tendency in the direction of astrology, discussing the music of the spheres in the first chapters of the Catoptrics, and in the Pneumatics describing an absurdly simple representation of the cosmos by means of a small sphere placed in a circular hole in the partition between two halves of a transparent sphere of glass. One hemisphere is to be filled with water, probably in order to support the ball in the center.[894] The marvelous virtues of animals other than automatons are rather out of his line, but he alludes to the virtue of the marine torpedo which can penetrate bronze, iron, and other bodies.

Although we have seen some indications of its earlier existence in Egypt, alchemy seems to have made its appearance in the ancient Greek-speaking and Latin world only at a late date. There seems to be no allusion to the subject in classical literature before the Christian era, the first mention being Pliny’s statement that Caligula made gold from orpiment.[895] The papyri containing alchemistic texts are of[Pg 194] the third century, and the manuscripts containing Greek works of alchemy, of which the oldest is one of the eleventh century in the Library of St. Mark’s, seem to consist of works or remnants of works written in the third century and later, many being Byzantine compilations, excerpts, or additions. Also Syncellus, the polygraph of the eighth century, gives some extracts from the alchemists.

Syncellus and other late writers[896] are our only extant sources for the statement that Diocletian burned the books of the alchemists in Egypt, so that they might not finance future revolts against him. If the report be true, one would fancy that the imperial edict would be more effective as a testimonial to the truth of transmutation in encouraging the art than it would be in discouraging it by destroying a certain amount of its literature. Thus the edict would resemble the occasional laws of earlier emperors banishing the astrologers—except their own—from Rome or Italy because they had been too free in predicting the death of the emperor, which only serve to show what a hold astrology had both on emperors and people. But the report concerning Diocletian sounds improbable on the face of it and must be doubted for want of contemporary evidence. Certainly we are not justified in explaining the air of secrecy so often assumed by writers on alchemy as due to the fear of persecution which this action of Diocletian[897] or the fear of being accused of magic aroused in them. Persons who wish to keep matters secret do not rush into publication, and the air of secrecy of the alchemists is too often evidently assumed for purposes of[Pg 195] show and to impress the reader with the idea that they really have something to hide. Sometimes the alchemists themselves realize that this adoption of an air of secrecy has been overdone. Thus Olympiodorus wrote in the early fifth century, “The ancients were accustomed to hide the truth, to veil or obscure by allegories what is clear and evident to everybody.”[898] Nor can we accept the story of Diocletian’s burning the books of alchemy as the reason why none have reached us which can be certainly dated as earlier than the third century.

The alchemists themselves, of course, claimed for their art the highest antiquity. Zosimus of Panopolis, who seems to have written in the third century, says that the fallen angels instructed men in alchemy as well as in the other arts, and that it was the divine and sacred art of the priests and kings of Egypt, who kept it secret. We also have an address of Isis to her son Horus repeating the revelation made by Amnael, the first of the angels and prophets. To Moses are ascribed treatises on domestic chemistry and doubling the weight of gold.[899] The manuscripts of the Byzantine period discuss what “the ancients” meant by this or that, or purport to repeat what someone else said of some other person. Zosimus seems fond of citing himself in the texts reproduced by Berthelot, so that it may be questioned how much of his original works has been preserved. Hermes is often cited by the alchemists, although no work of alchemy ascribed to him has reached us from this early period. To Agathodaemon is ascribed a commentary on the oracle of Orpheus addressed to Osiris, dealing with the whitening and[Pg 196] yellowing of metals and other alchemical recipes. Other favorite authorities are Ostanes, whom we have elsewhere heard represented as the introducer of magic into the Greek world, and the philosopher Democritus, whom the alchemists represent as the pupil of Ostanes and whom we have already heard Pliny charge with devotion to magic. Seneca says in one of his letters that Democritus discovered a process to soften ivory, that he prepared artificial emerald, and colored vitrified substances. Diogenes Laertius ascribes to him a work on the juices of plants, on stones, minerals, metals, colors, and coloring glass. This was possibly the same as the four books on coloring gold, silver, stones, and purple ascribed to Democritus by Synesius in the fifth, and Syncellus in the eighth, century. More recent presumably than Ostanes and Democritus are the female alchemists, Cleopatra and Mary the Jewess, although one text represents Ostanes and his companions as conversing with Cleopatra. A few of the spurious works ascribed to these authors may have come into existence as early as the Hellenistic period, but those which have reached us, at least in their present form, seem to bear the marks of the Christian era and later centuries of the Roman Empire, if not of the early medieval and Byzantine periods. And those authors whose names seem genuine: Zosimus, Synesius, Olympiodorus, Stephanus, are of the third, fourth and fifth centuries, at the earliest.

The associations of the names above cited and the fact that pseudo-literature forms so large a part of the early literature of alchemy suggest its close connection at that time with magic. Whereas Vitruvius, although not personally inhospitable to occult theory, showed us the art of architecture free from magic, and Hero told how to perform apparent magic by means of mechanical devices and deceits, the Greek alchemists display entire faith in magic procedure with which their art is indissolubly intermingled. Indeed the papyri in which works of alchemy occur are primarily magic papyri, so that alchemy may be said to spring from the brow of magic. The same is only somewhat less true of the manuscripts. In[Pg 197] the earliest one of the eleventh century the alchemy is in the company of a treatise on the interpretation of dreams, a sphere of divination of life or death, and magic alphabets. The treatises of alchemy themselves are equally impregnated with magic detail. Cleopatra’s art of making gold employs concentric circles, a serpent, an eight-rayed star, and other magic figures. Physica et mystica, ascribed to Democritus, after a purely technical fragment on purple dye, invokes his master Ostanes from Hades, and then plunges into alchemical recipes. There are also frequent bits of astrology and suggestions of Gnostic influence. Often the encircling serpent Ouroboros, who bites or swallows his tail, is referred to.[900] Sometimes the alchemist puts a little gold into his mixture to act as a sort of nest egg, or mother of gold, and encourage the remaining substance to become gold too.[901] Or we read in a work ascribed to Ostanes of “a divine water” which “revives the dead and kills the living, enlightens obscurity and obscures what is clear, calms the sea and quenches fire. A few drops of it give lead the appearance of gold with the aid of God, the invisible and all-powerful....”[902]

These early alchemists are also greatly given to mystery and allegory. “Touch not the philosopher’s stone with your hands,” warns Mary the Jewess, “you are not of our race, you are not of the race of Abraham.”[903] In a tract concerning the serpent Ouroboros we read, “A serpent is stretched out guarding the temple. Let his conqueror begin by sacrifice, then skin him, and after having removed his flesh to the very bones, make a stepping-stone of it to enter the temple. Mount upon it and you will find the object sought. For the priest, at first a man of copper, has changed his color and nature and become a man of silver; a few days later, if you wish, you will find him changed into a man of gold.”[904] Or in the preparation of the aforesaid divine[Pg 198] water Ostanes tells us to take the eggs of the serpent of oak who dwells in the month of August in the mountains of Olympus, Libya, and the Taurus.[905] Synesius tells that Democritus was initiated in Egypt at the temple of Memphis by Ostanes, and Zosimus cites the instruction of Ostanes, “Go towards the stream of the Nile; you’ll find there a stone; cut it in two, put in your hand, and take out its heart, for its soul is in its heart.”[906] Zosimus himself often resorts to symbolic jargon to obscure his meaning, as in the description of the vision of a priest who was torn to pieces and who mutilated himself.[907] He, too, personifies the metals and talks of a man of gold, a tin man, and so on.[908] A brief example of his style will have to suffice, as these allegories of the alchemists are insufferably tedious reading. “Finally I had the longing to mount the seven steps and see the seven chastisements, and one day, as it chanced, I hit upon the path up. After several attempts I traversed the path, but on my return I lost my way and, profoundly discouraged, seeing no way out, I fell asleep. In my dream I saw a little man, a barber, clothed in purple robe and royal raiment, standing outside the place of punishment, and he said to me....”[909] When Zosimus was not dreaming dreams and seeing visions, he was usually citing ancient authorities.

At the same time even these early alchemists cannot be denied a certain scientific character, or at least a connection with natural science. Behind alchemy existed a constant experimental progress. “Alchemy,” said Berthelot, “rested upon a certain mass of practical facts that were known in antiquity and that had to do with the preparation of metals, their alloys, and that of artificial precious stones; it had there an experimental side which did not cease to progress during the entire medieval period until positive modern chemistry emerged from it.”[910] The various treatises of the Greek alchemists describe apparatus and experiments which are real[Pg 199] but with which they associated results which were impossible and visionary. Their theories of matter seem indebted to the earlier Greek philosophers, while in the description of nature Berthelot noted a “direct and intimate” relation between them and the works of Dioscorides, Vitruvius, and Pliny.[911]

Having noted the presence of magic in works so especially devoted to natural science as those of Pliny, Galen, and Ptolemy, we have now to illustrate the prominence both of natural science and of magic in the life and thought of the Roman Empire by a consideration of some writers of a more miscellaneous character, who should reflect for us something of the interests of the average cultured reader of that time. Of this type are Plutarch, Apuleius and Philostratus, whom we shall consider in the coming chapters in the order named, which also roughly corresponds to their chronological sequence.

Plutarch flourished during the reigns of Trajan and Hadrian at the turn of the first and second centuries, but The Letter on the Education of a Prince to Trajan[912] probably is not by him, and the legend that Hadrian was his pupil is a medieval invention. He was born in Boeotia about 46-48 A. D. and was educated in rhetoric and philosophy, science and mathematics, at Athens, where he was a student[Pg 201] when Nero visited Greece in 66 A. D. He also made several visits to Rome and resided there for some time. He held various public positions in the province of Achaea and in his small native town of Chaeronea, and had official connections with the Delphic oracle and amphictyony. Artemidorus in the Oneirocriticon states that Plutarch’s death was foreshadowed in a dream.[913]

With Plutarch’s celebrated Lives of Illustrious Men, as with narrative histories in general, we shall not be much concerned, although they of course abound in omens and portents, in bits of pseudo-science which details in his narrative bring to the mind of the biographer, and in cases of divination and magic. Thus theories are advanced to explain why birds dropped dead from mid-air at the shout set up by the Greeks at the Isthmian games when Flamininus proclaimed their freedom. Or we are told how Sulla received from the Chaldeans predictions of his future greatness, how in the dedication to his Memoirs he admonished Lucullus to trust in dreams, and how Lucullus’s mind was deranged by a love philter administered by his freedman in the hope of increasing his master’s affection towards him.[914] Such allusions and incidents abound also of course in Dio Cassius, Tacitus, and other Roman historians.

But we shall be concerned rather with Plutarch’s other writings, which are usually grouped together under the title of Morals, or, more appropriately, Miscellanies and Essays. Not only is there great variety in their titles, but in any given essay the attention is usually not strictly held to one theme or problem but the discussion diverges to other points. Some are by their very titles and form rambling dialogues, symposiacs, and table-talk, where the conversation lightly flits from one topic to other entirely different ones, never dwelling for long upon any one point and never re[Pg 202]turning to its starting-point. This dinner-table and drinking-bout type of cultured and semi-learned discourse has other extant ancient examples such as the Attic Nights of Aulus Gellius and the Deipnosophists of Athenaeus, but Plutarch will have to serve as our main illustration of it. His Essays reflect in motley guise and disordered array the fruits of extensive reading and a retentive memory in ancient philosophy, science, history, and literature.

The authenticity of some of the essays attributed to him has been questioned, and very likely with propriety, but for our purpose it is not important that they should all be by the same author so long as they represent approximately the same period and type of literature. The spurious treatise, De placitis philosophorum, we have already considered in the chapter on Galen, to whom it has also been ascribed. The essay On Rivers and Mountains we shall treat by itself in the present chapter. The De fato has also been called spurious.[915] Superstitious content is not a sufficient reason for denying that a treatise is by Plutarch,[916] since he is superstitious in writings of undoubted genuineness and since we have found the leading scientists of the time unable to exclude superstition from their works entirely. Moreover, many of the essays are in the form of conversations expressing the divergent views of different speakers, and it is not always possible to tell which shade of opinion Plutarch himself favors. Suffice it that the views expressed are those of men of education.

Plutarch does not specifically discuss magic under that name at any length in any of his essays, but does treat of[Pg 203] such subjects as superstition in general, dreams, oracles, demons, number, fate, the craftiness of animals, and other “natural questions.” Certain vulgar forms of magic, at least, were regarded by him with disapproval or incredulity.[917] He rejects as a fiction the statement that the women of Thessaly can draw down the moon by their spells, but thinks that the notion perhaps originated in the fact or story that Aglaonice, daughter of Hegetor, was so skilful in astrology or astronomy as to be able to foresee the occurrence of lunar eclipses, and that she deluded the people into believing that at such times she brought down the moon from heaven by charms and enchantments.[918] Thus we have one more instance of the union of magic and science, this time of pseudo-magic with real science as at other times of magic with pseudo-science.

The essay entitled περὶ δεισιδαιμονίας deals with superstition in the usual Greek sense of dread or excessive fear of demons and gods. We are accustomed to think of Hellenic paganism as a cheerful faith, full of naturalism, in which the gods were humanized and made familiar. Plutarch apparently regards normal religion as of this sort, and attacks the superstitious dread of the supernatural. He contends that such fear is worse, if anything, than atheism, for it makes men more unhappy and is an equal offense against the divinity, since it is at least as bad to believe ill of the gods as not to believe in them at all. Nothing indeed encourages the growth of atheism so much as the absurd practices and beliefs of such superstitious persons, “their words and[Pg 204] motions, their sorceries and magics, their runnings to and fro and beatings of drums, their impure rites and their purifications, their filthiness and chastity, their barbarian and illegal chastisements and abuse.”[919] Plutarch seems to be in part animated by the common prejudice against all other religions than one’s own, and speaks twice with distaste of Jewish Sabbaths. He also, however, as the passage just quoted shows, is opposed to the more extreme and debasing forms of magic, and declares that the superstitious man becomes a mere peg or post upon which all the old-wives hang any amulets and ligatures upon which they may chance.[920] He further condemns such historic instances of superstition as Nicias’s suspension of military operations during a lunar eclipse on the Sicilian expedition.[921] There was nothing terrible, says Plutarch, with his usual felicity of antithesis, in the periodic recurrence of the earth’s shadow upon the moon; but it was a terrible calamity that the shadow of superstition should thus darken the mind of a general at the very moment when a great crisis required the fullest use of his reason.

In the essay upon the demon of Socrates one of the speakers, attacking faith in dreams and apparitions, commends Socrates as one who did not reject the worship of the gods but who did purify philosophy, which he had received from Pythagoras and Empedocles full of phantasms and myths and the dread of demons, and reeling like a Bacchanal, and reduced it to facts and reason and truth.[922] Another of the company, however, objects that the demon of Socrates outdid the divination of Pythagoras.[923] These conflicting opinions may be applied in some measure to Plutarch himself. His censure of dread of demons and excessive superstition is not to be taken as a sign of scepticism on his part in oracles, dreams, or the demons themselves. To these matters we next turn.

[Pg 205]

Plutarch’s faith and interest in oracles in general and in the Delphian oracle of Apollo in particular are attested by three of his essays, the De defectu oraculorum, De Pythiae oraculis and De Ei apud Delphos. At the same time these essays attest the decline of the oracles from their earlier popularity and greatness. The oracular cave of Trophonius, of which we shall hear again in the Life of Apollonius of Tyana, also comes into Plutarch’s works, and the prophetic and apocalyptic vision is described of a youth who spent two nights and a day there in an endeavor to learn the nature of the demon of Socrates.[924]

Plutarch further had faith in divination in general, whether by dreams, sneezes or other omens: but he attempted to give a dignified philosophical and theological explanation of it. Few men receive direct divine revelation, in his opinion, but to many signs are given on which divination may be based.[925] He held that the human soul had a natural faculty of divination which might be exercised at favorable times and when the bodily state was not unfavorable.[926] A speaker in one of his dialogues justifies divination even from sneezes and like trivial occurrences upon the ground that as the faint beat of the pulse has meaning for the physician and a small cloud in the sky is for a skilful pilot a sign of impending storm, so the least thing may be a clue to the truly prophetic soul.[927] The extent of Plutarch’s faith in dreams may be inferred from his discussion of the problem, Why are dreams in autumn the least reliable?[928] First there is Aristotle’s suggestion that eating autumn fruit so disturbs the digestion that the soul is left little opportunity to exercise its prophetic faculty undistracted. If we accept the doctrine of Democritus that dreams are caused by images from other bodies and even minds or souls, which enter the body of the sleeper through the open pores and affect the mind, revealing to it the present passions and future de[Pg 206]signs of others,—if we accept this theory, it may be that the falling leaves in autumn disturb the air and ruffle these extremely thin and film-like emanations. A third explanation offered is that in the declining months of the year all our faculties, including that of natural divination, are in a state of decline. In the case of oracles like that at Delphi it is suggested that the Pythia’s natural faculty of divination is stimulated by “the prophetical exhalations from the earth” which induce a bodily state favorable to divination.[929] The god or demon, however, is the underlying and directing cause of the oracle.[930]

To the demons and their relations to the gods and to men we therefore next come. Plutarch’s view is that they are essential mediators between the gods and men. Just as one who should remove the air from between the earth and moon would destroy the continuity of the universe, so those who deny that there is a race of demons break off all intercourse between gods and men.[931] On the other hand, the theory of demons solves many doubts and difficulties.[932] When and where this doctrine originated is uncertain, whether among the magi about Zoroaster, or in Thrace with Orpheus, or in Egypt or Phrygia. Plutarch likens the gods to an equilateral, the demons to an isosceles, and human beings to a scalene triangle; and again compares the gods to sun and stars, the demons to the moon, and men to comets and meteors.[933] In the youth’s vision in the cave of Trophonius the moon appeared to belong to earthly demons, while those stars which have a regular motion were the demons of sages, and the wandering and falling stars the demons of men who have yielded to irrational passions.[934]

These suggestions that the moon and the air between earth and moon are the abode of the demons and this reminiscence of the Platonic doctrine of the soul and its migrations receive further confirmation in a discussion whether[Pg 207] the moon is inhabited in the essay, On the Face in the Moon. A story is there told[935] of a man who visited islands five days’ sail west of Britain, where Saturn is imprisoned and where there are demons serving him. This man who acquired great skill in astrology during his stay there stated upon his return to Europe that every soul after leaving the human body wanders for a time between earth and moon, but finally reaches the latter planet, where the Elysian fields are located, and there becomes a demon.[936] The demons do not always remain in the moon, however, but may come to earth to care for oracles or be imprisoned in a human body again for some crime.[937] The man who repeats the stranger’s story leaves it to his hearers, however, to believe it or not. But the struggle upward of human souls to the estate of demons is again described in the essay on the demon of Socrates,[938] where it is explained that those souls which have succeeded in freeing themselves from all union with the flesh become guardian demons and help those of their fellows whom they can reach, just as men on shore wade out as far as they can into the waves to rescue those sea-tossed, ship-wrecked mariners who have succeeded in struggling almost to land. The soul is plunged into the body, the uncorrupted mind or demon remains without.[939]

The demons differ from the gods in that they are mortal, though much longer-lived than men. Hesiod said that crows live nine times as long as men, stags four times as long as crows, ravens three times as long as stags, a phoenix nine times as long as a raven, and the nymphs ten times as long as the phoenix.[940] There are storms in the isles off Britain whenever one of the demons residing there dies.[941] Some demons are good spirits and others are evil; some are more passive and irrational than others; some delight in gloomy festivals, foul words, and even human sacrifice.[942]

[Pg 208]

Once a year in the neighborhood of the Red Sea a man is seen who spends the remainder of his time among “nymphs, nomads and demons.”[943] At his annual appearance many princes and great men come to consult him concerning the future. He also has the gift of tongues to the extent of understanding several languages perfectly. His speech is like sweetest music, his breath sweet and fragrant, his person the most graceful that his interlocutor had ever seen. He also was never afflicted with any disease, for once a month he ate the bitter fruit of a medicinal herb. As to the exact nature of Socrates’ demon there is some diversity of opinion. One man suggests that it was merely the sneezing of himself or others, sneezes on the left hand warning him to desist from his intended course of action, while a sneeze in any other quarter was interpreted by him as a favorable sign.[944] The weight of opinion, however, inclines towards the view that his demon did not appear to him as an apparition or phantasm, or even communicate with him as an audible voice, but by immediate impression upon his mind.[945]

Plutarch’s account of demons is the first of a number which we shall have occasion to note. As the discussion of them by Apuleius in the next chapter and the rather crude representation of them given in Philostratus’s Life of Apollonius of Tyana will show, there was as yet among non-Christian writers no unanimity of opinion concerning demons. On the other hand there are several conceptions in Plutarch’s essays which were to be continued later by Christians and Neo-Platonists: namely, the conception of a mediate class of beings between God and men, the hypothesis of a world of spirits in close touch with human life, the association of divination and oracles with demons, and the location of spirits in the sphere of the moon or the air between earth and moon,—although Plutarch sometimes connected demons with the stars above the moon. This occasional association of stars with spirits and of sinning souls with falling stars[Pg 209] bears some resemblance to the depiction of certain stars as sinners in the Hebraic Book of Enoch, which was written before Plutarch’s time and which we shall consider in our next book as an influence upon the development of early Christian thought.

As for the stars apart from demons, Plutarch discusses the art of astrology as little as he does “magic” by that name. Mentions of individuals as skilled in “astrology” may simply mean that they were trained astronomers. When a veritable astrologer in our sense of the word is mentioned in one of Plutarch’s Lives,[946] he is described as a μαθηματικός—a word often used for a caster of horoscopes and predicter of the future. Here, however, it carries no reproach of charlatanism, since in the same phrase he is called a philosopher. This Tarrutius was a friend of Varro, who asked him to work out the horoscope of Romulus backward from what was known of the later life and character of the founder of Rome. “For it was possible for the same science which predicted man’s life from the time of his birth to infer the time of his birth from the events of his life.” Tarrutius set to work and from the data at his disposal figured out that Romulus was conceived in the first year of the second Olympiad, on the twenty-third day of the Egyptian month Khoeak at the third hour when there was a total eclipse of the sun; and that he was born on the twenty-first day of the month Thoth about sunrise. He further estimated that Rome was founded by him on the ninth day of the month Pharmuthi between the second and third hour. For, adds Plutarch, they think that the fortunes of cities are also controlled by the hour of their genesis. Plutarch, however, seems to look upon such doctrines as rather strange and fabulous.[947] Varro, on the other hand, may have regarded it as the most scientific method possible of settling disputed questions of historical chronology

[Pg 210]

A favorable attitude towards astrology is found mainly in those essays by Plutarch which are suspected of being spurious, the De fato and De placitis philosophorum. Of the latter we have already treated under Galen. In the former fate is described as “the soul of the universe,” and the three main divisions of the universe, namely, the immovable heaven, the moving spheres and heavenly bodies, and the region about the earth, are associated with the three Fates, Clotho, Atropos, and Lachesis.[948] It is similarly stated in the essay on the demon of Socrates[949] that of the four principles of all things, life, motion, genesis or generation, and corruption, the first two are joined by the One indivisibly, the second and third Mind unites through the sun; the third and fourth Nature joins through the moon. And over each of these three bonds presides one of the three Fates, Atropos, Clotho, and Lachesis. In other words, the one God or first cause, invisible and unmoved, in whom is life, sets in motion the heavenly spheres and bodies, through whose instrumentality generation and corruption upon earth are produced and regulated,—which is substantially the Aristotelian view of the universe. Returning to the De fato we may note that it repeats the Stoic theory of the magnus annus when the heavenly bodies resume their rounds and all history repeats itself.[950] Despite this apparent admission that human life is subject to the movements of the stars, the author of the De fato seems to think that accident, fortune or chance, the contingent, and “what is in us” or free-will, can all co-exist with fate, which he practically identifies with the motion of the heavenly bodies.[951] Fate is also comprehended by divine Providence but this fact does not militate against astrology, since Providence itself divides into that of the first God, that of the secondary gods or stars “who move through the heavens regulating mortal affairs, and that of the demons who act as guardians of men.”[952]

[Pg 211]

One or two bits of astrology may be noted in Plutarch’s other essays. The man who learned “astrology” among demons in the isle beyond Britain affirmed that in human generation earth supplies the body, the moon furnishes the soul, and the sun provides the intellect.[953] In the Symposiacs[954] the opinion of the mythographers is repeated that monstrous animals were produced during the war with the giants because the moon turned from its course then and rose in unaccustomed quarters. Plutarch was, by the way, inclined to distinguish the moon from other heavenly bodies as passive and imperfect, a sort of celestial earth or terrestrial star. Such a separation of the moon from the other stars and planets would have, however, no necessary contrariety with astrological theory, which usually ascribed a peculiar place to the moon and represented it as the medium through which the more distant planets exerted their effects upon the earth.

Sometimes Plutarch’s cosmology carries Platonism to the verge of Gnosticism, a subject of which we shall treat in a later chapter. The diviner who had communed with demons, nomads, and nymphs in the desert asserted that there was not one world, but one hundred and eighty-three worlds arranged in the form of a triangle with sixty to each side and one at each angle. Within this triangle of worlds lay the plain of truth where were the ideas and models of all things that had been or were to be, and about these was eternity from which time flowed off like a river to the one hundred and eighty-three worlds. The vision delectable of those ideas is granted to men only once in a myriad of years, if they live well, and is the goal toward which all philosophy strives. The stranger, we are informed, told this tale artlessly, like one in the mysteries, and produced no demonstration or proof of what he said. We have already heard Plutarch liken gods, demons, and men to different kinds of triangles; he also repeats Plato’s association of the[Pg 212] five regular solids with the elements, earth, air, fire, water, and ether.[955] He states that the nature of fire is quite apparent in the pyramid from “the slenderness of its decreasing sides and the sharpness of its angles,”[956] and that fire is engendered from air when the octahedron is dissolved into pyramids, and air produced from fire when the pyramids are compressed into an octahedron.[957]

These geometrical fancies are naturally accompanied by considerable number mysticism. In this particular passage the merits of the number five are enlarged upon and a long list is given of things that are five in number.[958] Five is again extolled in the essay on The Ei at Delphi,[959] but there one of the company remarks with much reason that it is possible to praise any number in many ways, but that he prefers to five “the sacred seven of Apollo.”[960] Platonic geometrical reveries and Pythagorean number mysticism are indulged in even more extensively in the essay On the Procreation of the Soul in Timaeus. The number and proportion existing in planets, stars and spheres are touched on,[961] and it is stated that the divine demiurge produced the marvelous virtues of drugs and organs by employing harmonies and numbers.[962] Thus in the potency of number and numerical relations is suggested a possible explanation of astrology and magic force in nature.

Plutarch, indeed, shows the same faith in the existence of occult virtues in natural objects and in what may be called natural magic as most of his contemporaries. At his symposium when one man avers that he saw the tiny fish echeneïs stop the ship upon which he was sailing until the lookout man picked it off,[963] some laugh at his credulity but[Pg 213] others narrate other cases of strange antipathies in nature. Mad elephants are quieted by the sight of a ram; vipers will not move if touched with a leaf from a beech tree; wild bulls become tame when tied to a fig tree;[964] if light objects are oiled, amber fails to attract them as usual; and iron rubbed with garlic does not respond to the magnet. “These things are proved by experience but it is difficult if not quite impossible to learn their cause.” At the Symposium[965] the question also is raised why salt is called divine, and it is suggested that it may be because it preserves bodies from decay after the soul has left them, or because mice conceive without sexual intercourse by merely licking salt. In The Delay of the Deity Plutarch again treats of occult virtues.[966] They pass from body to body with incredible swiftness or to an incredible distance. He wonders why it is that if a goat takes a piece of sea-holly in her mouth, the entire herd will stand still until the goatherd removes it. We see once more how closely such notions are associated with magical practices, when in the same paragraph he mentions the custom of making the children of those who have died of consumption or dropsy sit soaking their feet in water until the corpse has been buried so that they may not catch their parent’s disease.

On the other hand, how difficult it must have been with the limited scientific knowledge of that time to distinguish true from false marvelous properties may be inferred from Plutarch’s description[967] of a certain soft and pliable stone that used to be produced at Carystus and from which handkerchiefs and hair-nets were made which could not be burnt and were cleaned by exposure to fire,—a description, it would seem, of our asbestos, although Plutarch does not give the stone any name. Strabo also ascribes similar properties to a stone from Carystus without naming it.[968] Dioscorides and[Pg 214] other Greek authors, we are told,[969] apply the word “asbestos” to quick-lime, but Pliny in the Natural History[970] describes what he says the Greeks call ἀσβέστινον much as Plutarch does. He adds that it is employed in making shrouds for royal funerals to separate the ashes of the corpse from those of the pyre.[971] But he seems to regard it as a plant, not a stone, listing it as a variety of linen in one of his books on vegetation. He also states incorrectly that it is found but rarely and in desert and arid regions of India where there is no rain and a hot sun and amid terrible serpents[972]. Probably Pliny or his source argued that anything which resisted the action of fire must have been inured by growth under fiery suns and among serpents. Furthermore it obviously should possess other marvelous properties, so we are not surprised to find Anaxilaus cited to the effect that if this “linen” is tied around a tree trunk, the blows with which the tree is felled cannot be heard. It was thus that imaginations inured to magic enlarged upon unusual natural properties.

[Pg 215]

A treatise upon rivers and mountains in which the marvelous virtues of herbs and stones figure very prominently has sometimes been included among the works of Plutarch, but also has been omitted entirely from some editions.[973] Some have ascribed it to Parthenius of the time of Nero. It is made up of some thirty-five chapters in each of which a river and a mountain are mentioned. Usually some myth or tragic history is recounted, from which the river took its name or with which it was otherwise intimately connected. A similar procedure is followed in the case of the mountain. The writer, whoever he may be, makes a show of extensive reading, citing over forty authorities, most of whom are Greek and not mentioned in the full bibliographies of Pliny’s Natural History. The titles cited have to do largely with stones, rivers, and different countries. It has been questioned, however, whether these citations are not bogus.[974]

The properties attributed to herbs and stones in this treatise are to a large extent magical. A white reed found in the river Phasis while one is sacrificing at dawn to Hecate, if strewn in a wife’s bedroom, drives mad any adulterer who enters and makes him confess his sin.[975] Another herb mentioned in the same chapter was used by Medea to protect Jason from her father. In a later chapter[976] we are told how Hera called upon Selene to aid her in securing her revenge upon Heracles, and how the moon goddess filled a large chest with froth and foam by her magic spells until presently a huge lion leaped out of the chest. Returning from such sorceresses as Hecate, Medea, and Selene to herbs alone, in other rivers are plants which test the purity of gold, aid dim sight or blind one, wither at the mention of the word “step-mother” or burst into flames whenever a step-mother has evil designs against her step-son, free their bearers from fear of apparitions, operate as charms in love-making and[Pg 216] childbirth, cure madmen of their frenzy, check quartan agues if applied to the breasts, protect virginity or wither at a virgin’s touch, turn wine into water except that it retains its bouquet, or preserve persons anointed with their juice from sickness to their dying day.

An easy transition from the theme of magic herbs to that of stones is afforded by a sort of poppy which grows in a river of Mysia and bears black, harp-shaped stones which the natives gather and scatter over their ploughed fields.[977] If these stones then lie still where they have fallen, it is taken as a sign of a barren year; but if they fly away like locusts, this prognosticates a plentiful harvest. Other marvelous stones are found in the head of a fish in the river Arar, a tributary of the Rhone. The fish is itself quite wonderful since it is white while the moon waxes and black when it wanes.[978] Presumably for this reason the stone cures quartan agues, if applied to the left side of the body while the moon is waning. There is another stone which must be sought after under a waxing moon with pipers playing continually.[979]

Other stones guard treasuries by sounding a trumpet-like alarm at the approach of thieves; or change color four times a day and are ordinarily visible only to young girls. But if a virgin of marriageable age chances to see this stone, she is safe from attempts upon her chastity henceforth.[980] Some stones drive men mad and are connected with the Mother of the Gods or are found only during the celebration of the mysteries.[981] Others stop dogs from barking, expel demons, grow black in the hands of false witnesses, protect from wild beasts, and have varied medicinal powers or other effects similar to those already mentioned in the case of herbs.[982] In a river where the Spartans were defeated is a stone which leaps towards the bank, if it hears a trumpet,[Pg 217] but sinks at the mention of the Athenians.[983] Certainly a marvelous stone, capable of both hearing and motion!

Leaving the treatise on rivers and mountains, for the occult virtue of human beings we may turn to a discussion of fascination in the Symposiacs.[984] Some of the company ridiculed the idea, but their host asserted that a myriad of events went to prove it and that if you reject a thing simply because you cannot give a reason for it, you “take away the marvelous from all things.” He pointed out that some men hurt little and tender children by looking at them, and argued that, as the plumes of other birds are ruined when mixed with those of the eagle, so men may injure by their touch or mere glance. Plutarch, who was of the company, suggested effluvia or emanations from the body as a possible explanation, pointing out that love begins with glances, that no disease is more contagious than sore eyes, and that gazing upon the curlew cures jaundice. The bird appears to attract the disease to itself, and averts its head and closes its eyes, not, as some think, because it is jealous of the remedy sought from it, but because it feels wounded as if from a blow. Others of the company contended that the passions and affections of the soul may have a powerful effect through the eyes and glance upon other persons, and argued that the sufferings of the soul strengthen the powers of the body, and that the same counter-charms are efficacious against envy as against fascination. The emanations which Democritus believed that envious and malicious persons sent forth are also mentioned; fathers have fascinated their own children, and it is even possible that one might injure oneself by reflection of one’s gaze. It is suggested that young children may sometimes be fascinated in this manner rather than by the glance of others.

Plutarch devotes two essays to the familiar theme of the craftiness and sagacity of animals and the remedies used by them. In one essay[985] a companion of Odysseus refuses to[Pg 218] allow Circe to turn him back from a pig to human form. He boasts among other things that beasts know how to cure themselves. Without ever having been taught swine when sick run to rivers to search for craw-fish; tortoises physic themselves with origanum after eating vipers; and Cretan goats devour dittany to extract arrows and darts which have been shot into their bodies. In the other essay[986] on the cleverness of animals we find many familiar stories repeated, including some of the inevitable excerpts from Juba on elephants. We meet again the dolphins with their love for mankind,[987] the bird who picks the crocodile’s teeth and warns him of the ichneumon,[988] the fish who rescue one another by biting the line or dragging one another by the tail out of nets,[989] the trained elephant who was slow to learn and was beaten for it and was afterwards seen practicing his exercises by himself in the moonlight,[990] the sentinel cranes who stand on one foot and hold a stone in the other to awaken them if they let it drop.[991] More novel perhaps is the story how herons open oysters by first swallowing them, shells and all, until they are relaxed by the internal heat of the bird, which then vomits them up and eats them out of the shells. Or the account of the tunny fish who needs no astrological canons and is familiar with arithmetic, “Yes, by Zeus, and with optics, too.”[992]

Plutarch’s essays bring out yet other interests and defects of the science of the time. One on The Principle of Cold is a good illustration of the failings of the ancient hypothesis of four elements and four qualities and of the silly, limited arguing which usually and almost of necessity accompanied it. He denies that cold is mere privation of heat, since it seems to act positively upon fluids and solids and exists in different degrees. After considering various assertions such as that air becomes cold when it becomes[Pg 219] dark; that air whitens things and water blackens them; that cold objects are always heavy; he finally associates the element earth especially with the quality cold. In another essay[993] he states that there are no females of a certain type of beetle which was engraved as a charm upon the rings warriors wore to battle, but that the males begat offspring by rolling up balls of earth. He declares that “diseases do not have distinct germs” in a discussion in the Symposiacs whether there can be new diseases.[994] Other natural questions discussed in the treatise of that name and the Symposiacs are: Why a man who often passes near dewy trees contracts leprosy in those limbs which touch the wood? Why the Dorians pray for bad hay-making? Why bears’ paws are the sweetest and most palatable food? Why the tracks of wild beasts smell worse at the full of the moon? Why bees are more apt to sting fornicators than other persons?[995] Why the flesh of sheep bitten by wolves is sweeter than that of other sheep? Why mushrooms are thought to be produced by thunder? Why flesh decays sooner in moonlight than sunlight? Whether Jews abstain from pork because they worship the pig or because they have an antipathy towards it?[996]

Plutarch sometimes shows evidence of considerable astronomical knowledge. For instance, he knows that the mathematicians figure that the distance from sun to earth is immense, and that Aristarchus demonstrated the sun to be eighteen or twenty times as far off as the moon, which is distant fifty-six times the earth’s radius at the lowest estimate.[997] Yet in the same essay[998] Plutarch has scoffed at the idea of a spherical earth and of antipodes, and at the assertion that bars weighing a thousand talents would stop falling at the earth’s center, if a hole were opened up through the earth, or that two men with their feet in opposite directions[Pg 220] at the center of the earth might nevertheless both be right side up, or that one man whose middle was at the center might be half right side up and half upside down. He admits, however, that the philosophers think so. Thus we see that Christian fathers like Lactantius were not the first to ridicule the notion of the Antipodes; apparently as well educated and omnivorous a pagan reader as Plutarch could do the same.

One of the fullest and most vivid pictures of magic in the ancient Mediterranean world which has reached us is provided by the writings of Apuleius. He lived in the second century of our era and was not merely a rhetorician of great note in his day and the writer of a romance which has ever since fascinated men, but also a Platonic philosopher, an initiate into many religious cults and mysteries, and a student of natural science and medicine. To him has been ascribed the Latin version of Asclepius, a supposititious dialogue of Hermes Trismegistus. No author perhaps ever more readily and complacently talked of himself than[Pg 222] Apuleius, yet it is no easy task to make out the precise facts of his life, partly because in his romance, The Metamorphoses, or The Golden Ass, he has hopelessly confused himself with the hero Lucius and introduced an autobiographical element of uncertain extent into what is in the main a work of fiction; partly because his Apology, or defense when tried on the charge of magic at Oea in Africa, is more in the nature of special pleading intended to refute and confound his accusers than of a frank confession or accurate history of his career. However, he appears to have been born at Madaura in North Africa, to have studied first at Carthage and then at Athens, to have visited Rome and wandered rather widely about the Mediterranean world, but to have spent more time altogether at Carthage than at any other one place.

Besides the Metamorphoses and Apologia, with which we shall be chiefly concerned, four other works are extant which are regarded as genuine, The God of Socrates, The Dogma of Plato, Florida, and On the Universe. The order in which these works were written is uncertain, but it seems almost sure that the Metamorphoses was the first. In it Apuleius not only more or less identifies himself with the hero Lucius, who is represented as quite a young man, he also apologizes for his Latin and speaks of the difficulty with which he had acquired that language at Rome. But in the Florida[999] we find him repeating a hymn and a dialogue in both Latin and Greek, or, after delivering half an address in Greek, finishing it in Latin, or boasting that he writes poems, satires, riddles, histories, scientific treatises, orations, and philosophical dialogues with equal facility in either language.[1000] Instead now of craving pardon if he offends by his rude, exotic, and forensic speech, he feels that his reputation for literary refinement and elegance has become such that his audience will not pardon him a solitary solecism or a single syllable pronounced with a barbarous accent.[1001] It[Pg 223] therefore looks as if the Metamorphoses was his first published effort in Latin and as if his peculiar style had proved so popular that he did not find it necessary to apologize for it again. In the Apology he seems supremely confident of his rhetorical powers in the Latin language, and even the accusers describe him as a philosopher of great eloquence both in Greek and Latin.[1002] Three years before in the same town his first public discourse had been greeted with shouts of “Insigniter,” and many in the audience at the time of his trial can still repeat a passage from it on the greatness of Aesculapius.[1003] In the Apology, too, he displays a more extensive learning than in the Metamorphoses and has written already poems and scientific treatises as well as orations. Indeed, practically all the doctrines set forth in his other philosophical works may be found in brief in the Apology.

Moreover, while in the Metamorphoses Apuleius ends the narrative with what seems to be his own comparatively recent initiation into the mysteries of Isis in Greece and of Osiris at Rome, in the Apology[1004] he speaks of having been initiated in the past into all sorts of sacred rites, although he does not mention Rome or Isis and Osiris specifically. It is implied, however, that he has been at Rome in more than one passage of the Apology. Pontianus, his future step-son, with whom Apuleius had become acquainted at Athens “not so many years ago,” was “an adult at Rome” before Apuleius came to Oea. After they had met again at Oea and had both married there, Apuleius gave Pontianus a letter of introduction to the proconsul Lollianus Avitus at Carthage, of whom he says, “I have known intimately many cultured men of Roman name in the course of my life, but have never admired anyone as much as him.” Perhaps Apuleius may have met Lollianus at Carthage, but in the Florida,[1005] in a panegyric on Scipio Orfitus, proconsul of Africa in 163-164 A. D., he alludes to the time “when I moved among your friends in Rome.” All this fits in nicely[Pg 224] with the statements in the closing chapters of the Metamorphoses concerning his rising fame as an orator in the courts of law and “the laborious doctrine of my studies” at Rome. We may therefore reconstruct the course of events as follows. After meeting Pontianus at Athens and concluding his studies in Greece, Apuleius came to Rome, where he remained for some time, perfecting his Latin style, engaging in forensic oratory, and publishing the Metamorphoses. Pontianus, who was younger than Apuleius, either accompanied or followed his friend to Rome, in which city he was still residing after Apuleius had returned to Africa. But Pontianus, too, had left Rome and come back to his African city of Oea to settle the question of his mother’s proposed second marriage, before Apuleius, who had probably revisited Carthage in the meantime and was now traveling east again with the intention of visiting Alexandria, arrived at Oea and was induced to wed the widow, who was considerably older than he. On the delicate question of this lady’s exact age depends our dating of the birth of Apuleius and the chronology of his entire career. At the trial of Apuleius for magic Aemilianus, the accuser, declared that she was sixty when she married Apuleius, and he had previously proposed to marry her to his brother, Clarus, whom Apuleius calls “a decrepit old man.”[1006] On the other hand, Apuleius asserts that the records, which he produces in court, of her being accepted in infancy by her father as his child show that she is “not much over forty,”[1007]—a tactful ambiguity which, inasmuch as we no longer have the records, it would probably be idle to attempt to fathom.

The chief, if not the only, objection to dating the Metamorphoses before the Apology is that nothing is said of it in the latter.[1008] But obviously Apuleius, when on trial for magic, would not mention the Metamorphoses unless his[Pg 225] accusers forced him to do so. They may not have yet heard of it or it may at first have been published anonymously, although the probability is that Apuleius would not have spent three years at Oea without bringing it to his admirers’ attention. Or they may know of it, but the judge may not have admitted it as evidence on the ground that they must prove that Apuleius has practiced magic. The Metamorphoses does not recount any personal participation of Apuleius himself in magic arts, unless one identifies him throughout with the hero Lucius; it purports to be a Latin rendition of Milesian tales[1009] and does not seem to have been taken very seriously until the church fathers began to cite it. Or the accusers may have dwelt upon it and Apuleius simply have failed to take notice of their charge. All these suppositions may not seem very plausible, but on the other hand we may ask, how would Apuleius dare to write a work like the Metamorphoses after he had been accused and tried of magic? One would expect him then to drop the subject rather than to display an increasing interest in it. But let us turn to his treatment of that theme in both those works, and first consider the Metamorphoses.
