ASTROLOGY AND DIVINATION

AT this period astrology, which included astronomy, was everywhere taught. In the "Gouernaunce of Prynces, or Pryvete of Pryveties," translated by James Yonge, 1422,(26) there occurs the statement: "As Galian the lull wies leche Saith and Isoder the Gode clerk, hit witnessith that a man may not perfitely can the sciens and craft of Medissin but yef he be an astronomoure."

We have seen how the practice of astrology spread from Babylonia and Greece throughout the Roman Empire. It was carried on into the Middle Ages as an active and aggressive cult, looked upon askance at times by the Church, but countenanced by the courts, encouraged at the universities, and always by the public. In the curriculum of the mediaeval university, astronomy made up with music, arithmetic and geometry the Quadrivium. In the early faculties, astronomy and astrology were not separate, and at Bologna, in the early fourteenth century, we meet with a professorship of astrology.(27) One of the duties of this salaried professor, was to supply "judgements" gratis for the benefit of enquiring students, a treacherous and delicate assignment, as that most distinguished occupant of the chair at Bologna, Cecco d'Ascoli, found when he was burned at the stake in 1357, a victim of the Florentine Inquisition.(28)

Roger Bacon himself was a warm believer in judicial astrology and in the influence of the planets, stars and comets on generation, disease and death.

Many of the stronger minds of the Renaissance broke away from the follies of the subject. Thus Cornelius Agrippa in reply to the request of a friar to consult the stars on his behalf says:(29) "Judicial astrology is nothing more than the fallacious guess of superstitious men, who have founded a science on uncertain things and are deceived by it: so think nearly all the wise; as such it is ridiculed by some most noble philosophers; Christian theologians reject it, and it is condemned by sacred councils of the Church. Yet you, whose office it is to dissuade others from these vanities, oppressed, or rather blinded by I know not what distress of mind, flee to this as to a sacred augur, and as if there were no God in Israel, that you send to inquire of the god of Ekron."

In spite of the opposition of the Church astrology held its own; many of the universities at the end of the fifteenth century published almanacs, usually known as "Prognosticons," and the practice was continued far into the sixteenth century. I show you here an illustration. Rabelais, you may remember, when physician to the Hotel Dieu in Lyons, published almanacs for the years 1533, 1535, 1541, 1546. In the title-page he called himself "Doctor of Medicine and Professor of Astrology," and they continued to be printed under his name until 1556. In the preparation of these he must have had his tongue in his cheek, as in his famous "Pantagrueline Prognostication," in which, to satisfy the curiosity of all good companions, he had turned over all the archives of the heavens, calculated the quadratures of the moon, hooked out all that has ever been thought by all the Astrophils, Hypernephilists, Anemophylakes, Uranopets and Ombrophori, and felt on every point with Empedocles.(30)

Even physicians of the most distinguished reputation practised judicial astrology. Jerome Cardan was not above earning money by casting horoscopes, and on this subject he wrote one of his most popular books (De Supplemento Almanach, etc., 1543), in which astronomy and astrology are mixed in the truly mediaeval fashion. He gives in it some sixty-seven nativities, remarkable for the events they foretell, with an exposition. One of the accusations brought against him was that he had "attempted to subject to the stars the Lord of the stars and cast our Saviour's horoscope."(31) Cardan professed to have abandoned a practice looked upon with disfavor both by the Church and by the universities, but he returned to it again and again. I show here his own horoscope. That remarkable character, Michael Servetus, the discoverer of the lesser circulation, when a fellow student with Vesalius at Paris, gave lectures upon judicial astrology, which brought him into conflict with the faculty; and the rarest of the Servetus works, rarer even than the "Christianismi Restitutio," is the "Apologetica disceptatio pro astrologia," one copy of which is in the Bibliotheque Nationale. Nor could the new astronomy and the acceptance of the heliocentric views dislocate the popular belief. The literature of the seventeenth century is rich in astrological treatises dealing with medicine.

No one has ever poured such satire upon the mantic arts as did Rabelais in chapter twenty-five of the third book of "Pantagruel." Panurge goes to consult Her Trippa—the famous Cornelius Agrippa, whose opinion of astrology has already been quoted, but who nevertheless, as court astrologer to Louise of Savoy, had a great contemporary reputation. After looking Panurge in the face and making conclusions by metoposcopy and physiognomy, he casts his horoscope secundum artem, then, taking a branch of tamarisk, a favorite tree from which to get the divining rod, he names some twenty-nine or thirty mantic arts, from pyromancy to necromancy, by which he offers to predict his future. While full of rare humor, this chapter throws an interesting light on the extraordinary number of modes of divination that have been employed. Small wonder that Panurge repented of his visit! I show here the title-page of a popular book by one of the most famous of the English astrological physicians, Nicholas Culpeper.

Never was the opinion of sensible men on this subject better expressed than by Sir Thomas Browne:(32) "Nor do we hereby reject or condemn a sober and regulated Astrology; we hold there is more truth therein than in ASTROLOGERS; in some more than many allow, yet in none so much as some pretend. We deny not the influence of the Starres, but often suspect the due application thereof; for though we should affirm that all things were in all things; that Heaven were but Earth Celestified, and earth but Heaven terrestrified, or that each part above had an influence upon its divided affinity below; yet how to single out these relations, and duly to apply their actions, is a work ofttimes to be effected by some revelation, and Cabala from above, rather than any Philosophy, or speculation here below."

As late as 1699, a thesis was discussed at the Paris Faculty, "Whether comets were harbingers of disease," and in 1707 the Faculty negatived the question propounded in a thesis, "Whether the moon had any sway on the human body."

The eighteenth and nineteenth centuries saw, among intelligent men, a progressive weakening of the belief in the subject; but not even the satire of Swift, with his practical joke in predicting and announcing the death of the famous almanac maker, nor contemptuous neglect of the subject of late years sufficed to dispel the belief from the minds of the public. Garth in the Dispensary (1699) satirizes the astrological practitioners of his day:

The almanacs of Moore and Zadkiel continue to be published, and remain popular. In London, sandwich men are to be met with carrying advertisements of Chaldeans and Egyptians who offer to tell your fortune by the stars. Even in this country, astrology is still practiced to a surprising extent if one may judge from advertisements in certain papers, and from publications which must have a considerable sale. Many years ago, I had as a patient an estimable astrologer, whose lucrative income was derived from giving people astral information as to the rise and fall of stocks. It is a chapter in the vagaries of the human mind that is worth careful study.(33) Let me commend to your reading the sympathetic story called "A Doctor of Medicine" in the "Rewards and Fairies" of Kipling. The hero is Nicholas Culpeper, Gent., whose picture is here given. One stanza of the poem at the end of the story, "Our Fathers of Old," may be quoted:

James J. Walsh of New York has written a book of extraordinary interest called "The Thirteenth, Greatest of Centuries." I have not the necessary knowledge to say whether he has made out his case or not for art and for literature. There was certainly a great awakening and, inspired by high ideals, men turned with a true instinct to the belief that there was more in life than could be got out of barren scholastic studies. With many of the strong men of the period one feels the keenest mental sympathy. Grosseteste, the great Clerk of Lincoln, as a scholar, a teacher and a reformer, represents a type of mind that could grow only in fruitful soil. Roger Bacon may be called the first of the moderns—certainly the first to appreciate the extraordinary possibilities which lay in a free and untrammelled study of nature. A century which could produce men capable of building the Gothic cathedrals may well be called one of the great epochs in history, and the age that produced Dante is a golden one in literature. Humanity has been the richer for St. Francis; and Abelard, Albertus and Aquinas form a trio not easy to match, in their special departments, either before or after. But in science, and particularly in medicine, and in the advance of an outlook upon nature, the thirteenth century did not help man very much. Roger Bacon was "a voice crying in the wilderness," and not one of the men I have picked out as specially typical of the period instituted any new departure either in practice or in science. They were servile followers, when not of the Greeks, of the Arabians. This is attested by the barrenness of the century and a half that followed. One would have thought that the stimulus given by Mundinus to the study of anatomy would have borne fruit, but little was done in science during the two and a half centuries that followed the delivery of his lectures and still less in the art. While William of Wykeham was building Winchester Cathedral and Chaucer was writing the Canterbury Tales, John of Gaddesden in practice was blindly following blind leaders whose authority no one dared question.

The truth is, from the modern standpoint the thirteenth was not the true dawn brightening more and more unto the perfect day, but a glorious aurora which flickered down again into the arctic night of mediaevalism.

To sum up—in medicine the Middle Ages represent a restatement from century to century of the facts and theories of the Greeks modified here and there by Arabian practice. There was, in Francis Bacon's phrase, much iteration, small addition. The schools bowed in humble, slavish submission to Galen and Hippocrates, taking everything from them but their spirit and there was no advance in our knowledge of the structure or function of the body. The Arabians lit a brilliant torch from Grecian lamps and from the eighth to the eleventh centuries the profession reached among them a position of dignity and importance to which it is hard to find a parallel in history.
