But, while the inherited ideas of Church leaders were thus unfavourable to any proper development of medical science, there were two bodies of men outside the Church who, though largely fettered by superst.i.tion, were far less so than the monks and students of ecclesiastical schools: these were the Jews and Mohammedans. The first of these especially had inherited many useful sanitary and hygienic ideas, which had probably been first evolved by the Egyptians, and from them transmitted to the modern world mainly through the sacred books attributed to Moses.

The Jewish scholars became especially devoted to medical science. To them is largely due the building up of the School of Salerno, which we find flourishing in the tenth century. Judged by our present standards its work was poor indeed, but compared with other medical instruction of the time it was vastly superior: it developed hygienic principles especially, and brought medicine upon a higher plane.

Still more important is the rise of the School of Montpellier; this was due almost entirely to Jewish physicians, and it developed medical studies to a yet higher point, doing much to create a medical profession worthy of the name throughout southern Europe.

As to the Arabians, we find them from the tenth to the fourteenth century, especially in Spain, giving much thought to medicine, and to chemistry as subsidiary to it. About the beginning of the ninth century, when the greater Christian writers were supporting fetich by theology, Almamon, the Moslem, declared, "They are the elect of G.o.d, his best and most useful servants, whose lives are devoted to the improvement of their rational faculties." The influence of Avicenna, the translator of the works of Aristotle, extended throughout all Europe during the eleventh century. The Arabians were indeed much fettered by tradition in medical science, but their translations of Hippocrates and Galen preserved to the world the best thus far developed in medicine, and still better were their contributions to pharmacy: these remain of value to the present hour.(303)

x, p. 42. For the services of both Jews and Arabians, see Bedarride, Histoire des Juifs, p. 115; also Sismondi, Histoire des Francais, tome i, p. 191.

For the tendency of the Mosaic books to insist on hygienic rather than therapeutical treatment, and its consequences among Jewish physicians, see Sprengel, but especially Fredault, p.14.

Various Christian laymen also rose above the prevailing theologic atmosphere far enough to see the importance of promoting scientific development. First among these we may name the Emperor Charlemagne; he and his great minister, Alcuin, not only promoted medical studies in the schools they founded, but also made provision for the establishment of botanic gardens in which those herbs were especially cultivated which were supposed to have healing virtues. So, too, in the thirteenth century, the Emperor Frederick II, though under the ban of the Pope, brought together in his various journeys, and especially in his crusading expeditions, many Greek and Arabic ma.n.u.scripts, and took special pains to have those which concerned medicine preserved and studied; he also promoted better ideas of medicine and embodied them in laws.

Men of science also rose, in the stricter sense of the word, even in the centuries under the most complete sway of theological thought and ecclesiastical power; a science, indeed, alloyed with theology, but still infolding precious germs. Of these were men like Arnold of Villanova, Bertrand de Gordon, Albert of Bollstadt, Basil Valentine, Raymond Lully, and, above all, Roger Bacon; all of whom cultivated sciences subsidiary to medicine, and in spite of charges of sorcery, with possibilities of imprisonment and death, kept the torch of knowledge burning, and pa.s.sed it on to future generations.(304)

(304) For the progress of sciences subsidiary to medicine even in the darkest ages, see Fort, pp. 374, 375; also Isensee, Geschichte der Medicin, pp. 225 et seq.; also Monteil, p. 89; h.e.l.ler, Geschichte der Physik, vol. i, bk. 3; also Kopp, Geschichte der Chemie. For Frederick II and his Medicinal-Gesetz, see Baas, p. 221, but especially Von Raumer, Geschichte der Hohenstaufen, Leipsic, 1872, vol. iii, p. 259.

From the Church itself, even when the theological atmosphere was most dense, rose here and there men who persisted in something like scientific effort. As early as the ninth century, Bertharius, a monk of Monte Ca.s.sino, prepared two ma.n.u.script volumes of prescriptions selected from ancient writers; other monks studied them somewhat, and, during succeeding ages, scholars like Hugo, Abbot of St. Denis,--Notker, monk of St. Gall,--Hildegard, Abbess of Rupertsberg,--Milo, Archbishop of Beneventum,--and John of St. Amand, Canon of Tournay, did something for medicine as they understood it. Unfortunately, they generally understood its theory as a mixture of deductions from Scripture with dogmas from Galen, and its practice as a mixture of incantations with fetiches.

Even Pope Honorius III did something for the establishment of medical schools; but he did so much more to place ecclesiastical and theological fetters upon teachers and taught, that the value of his gifts may well be doubted. All germs of a higher evolution of medicine were for ages well kept under by the theological spirit. As far back as the sixth century so great a man as Pope Gregory I showed himself hostile to the development of this science. In the beginning of the twelfth century the Council of Rheims interdicted the study of law and physic to monks, and a mult.i.tude of other councils enforced this decree. About the middle of the same century St. Bernard still complained that monks had too much to do with medicine; and a few years later we have decretals like those of Pope Alexander III forbidding monks to study or practise it. For many generations there appear evidences of a desire among the more broad-minded churchmen to allow the cultivation of medical science among ecclesiastics: Popes like Clement III and Sylvester II seem to have favoured this, and we even hear of an Archbishop of Canterbury skilled in medicine; but in the beginning of the thirteenth century the Fourth Council of the Lateran forbade surgical operations to be practised by priests, deacons, and subdeacons; and some years later Honorius III reiterated this decree and extended it. In 1243 the Dominican order forbade medical treatises to be brought into their monasteries, and finally all partic.i.p.ation of ecclesiastics in the science and art of medicine was effectually prevented.(305)

VII. THEOLOGICAL DISCOURAGEMENT OF MEDICINE.

While various churchmen, building better than they knew, thus did something to lay foundations for medical study, the Church authorities, as a rule, did even more to thwart it among the very men who, had they been allowed liberty, would have cultivated it to the highest advantage.

Then, too, we find cropping out every where the feeling that, since supernatural means are so abundant, there is something irreligious in seeking cure by natural means: ever and anon we have appeals to Scripture, and especially to the case of King Asa, who trusted to physicians rather than to the priests of Jahveh, and so died. Hence it was that St. Bernard declared that monks who took medicine were guilty of conduct unbecoming to religion. Even the School of Salerno was held in aversion by mult.i.tudes of strict churchmen, since it prescribed rules for diet, thereby indicating a belief that diseases arise from natural causes and not from the malice of the devil: moreover, in the medical schools Hippocrates was studied, and he had especially declared that demoniacal possession is "nowise more divine, nowise more infernal, than any other disease." Hence it was, doubtless, that the Lateran Council, about the beginning of the thirteenth century, forbade physicians, under pain of exclusion from the Church, to undertake medical treatment without calling in ecclesiastical advice.

This view was long cherished in the Church, and nearly two hundred and fifty years later Pope Pius V revived it by renewing the command of Pope Innocent and enforcing it with penalties. Not only did Pope Pius order that all physicians before administering treatment should call in "a physician of the soul," on the ground, as he declares, that "bodily infirmity frequently arises from sin," but he ordered that, if at the end of three days the patient had not made confession to a priest, the medical man should cease his treatment, under pain of being deprived of his right to practise, and of expulsion from the faculty if he were a professor, and that every physician and professor of medicine should make oath that he was strictly fulfilling these conditions.

Out of this feeling had grown up another practice, which made the development of medicine still more difficult--the cla.s.sing of scientific men generally with sorcerers and magic-mongers: from this largely rose the charge of atheism against physicians, which ripened into a proverb, "Where there are three physicians there are two atheists."(306)

(306) "Ubi sunt tres medici ibi sunt duo athei." For the bull of Pius V, see the Bullarium Romanum, ed. Gaude, Naples, 1882, tom. vii, pp. 430, 431.

Magic was so common a charge that many physicians seemed to believe it themselves. In the tenth century Gerbert, afterward known as Pope Sylvester II, was at once suspected of sorcery when he showed a disposition to adopt scientific methods; in the eleventh century this charge nearly cost the life of Constantine Africa.n.u.s when he broke from the beaten path of medicine; in the thirteenth, it gave Roger Bacon, one of the greatest benefactors of mankind, many years of imprisonment, and nearly brought him to the stake: these cases are typical of very many.

Still another charge against physicians who showed a talent for investigation was that of Mohammedanism and Averroism; and Petrarch stigmatized Averroists as "men who deny Genesis and bark at Christ."(307)

(307) For Averroes, see Renan, Averroes et l'Averroisme, Paris, 1861, pp. 327-335. For a perfectly just statement of the only circ.u.mstances which can justify a charge of atheism, see Rev. Dr. Deems, in Popular Science Monthly, February, 1876.

The effect of this widespread ecclesiastical opposition was, that for many centuries the study of medicine was relegated mainly to the lowest order of pract.i.tioners. There was, indeed, one orthodox line of medical evolution during the later Middle Ages: St. Thomas Aquinas insisted that the forces of the body are independent of its physical organization, and that therefore these forces are to be studied by the scholastic philosophy and the theological method, instead of by researches into the structure of the body; as a result of this, mingled with survivals of various pagan superst.i.tions, we have in anatomy and physiology such doctrines as the increase and decrease of the brain with the phases of the moon, the ebb and flow of human vitality with the tides of the ocean, the use of the lungs to fan the heart, the function of the liver as the seat of love, and that of the spleen as the centre of wit.

Closely connected with these methods of thought was the doctrine of signatures. It was reasoned that the Almighty must have set his sign upon the various means of curing disease which he has provided: hence it was held that bloodroot, on account of its red juice, is good for the blood; liverwort, having a leaf like the liver, cures diseases of the liver; eyebright, being marked with a spot like an eye, cures diseases of the eyes; celandine, having a yellow juice, cures jaundice; bugloss, resembling a snake's head, cures snakebite; red flannel, looking like blood, cures blood-taints, and therefore rheumatism; bear's grease, being taken from an animal thickly covered with hair, is recommended to persons fearing baldness.(308)

(308) For a summary of the superst.i.tions which arose under the theological doctrine of signatures, see Dr. Eccles's admirable little tract on the Evolution of Medical Science, p. 140; see also Scoffern, Science and Folk Lore, p. 76.

Still another method evolved by this theological pseudoscience was that of disgusting the demon with the body which he tormented--hence the patient was made to swallow or apply to himself various unspeakable ordures, with such medicines as the livers of toads, the blood of frogs and rats, fibres of the hangman's rope, and ointment made from the body of gibbeted criminals. Many of these were survivals of heathen superst.i.tions, but theologic reasoning wrought into them an orthodox significance. As an example of this mixture of heathen with Christian magic, we may cite the following from a medieval medical book as a salve against "nocturnal goblin visitors": "Take hop plant, wormwood, bishopwort, lupine, ash-throat, henbane, harewort, viper's bugloss, heathberry plant, cropleek, garlic, grains of hedgerife, githrife, and fennel. Put these worts into a vessel, set them under the altar, sing over them nine ma.s.ses, boil them in b.u.t.ter and sheep's grease, add much holy salt, strain through a cloth, throw the worts into running water.

If any ill tempting occur to a man, or an elf or goblin night visitors come, smear his body with this salve, and put it on his eyes, and cense him with incense, and sign him frequently with the sign of the cross.

His condition will soon be better."(309)

(309) For a list of unmentionable ordures used in Germany near the end of the seventeenth century, see Lammert, Volksmedizin und medizinischer Aberglaube in Bayern, Wurzburg, 1869, p. 34, note. For the English prescription given, see c.o.c.kayne, Leechdoms, Wort-cunning, and Star-craft of Early England, in the Master of the Rolls' series, London, 1865, vol. ii, pp. 345 and following. Still another of these prescriptions given by c.o.c.kayne covers three or four octavo pages. For very full details of this sort of sacred pseudo-science in Germany, with accounts of survivals of it at the present time, see Wuttke, Prof. der Theologie in Halle, Der Deutsche Volksaberglaube der Gegenwart, Berlin, 1869, pa.s.sim. For France, see Rambaud, Histoire de la Civilisation francaise, pp. 371 et seq.

As to surgery, this same amalgamation of theology with survivals of pagan beliefs continued to check the evolution of medical science down to the modern epoch. The nominal hostility of the Church to the shedding of blood withdrew, as we have seen, from surgical practice the great body of her educated men; hence surgery remained down to the fifteenth century a despised profession, its practice continued largely in the hands of charlatans, and down to a very recent period the name "barber-surgeon" was a survival of this. In such surgery, the application of various ordures relieved fractures; the touch of the hangman cured sprains; the breath of a donkey expelled poison; friction with a dead man's tooth cured toothache.(310)

(310) On the low estate of surgery during the Middle Ages, see the histories of medicine already cited, and especially Kotelmann, Gesundheitspflege im Mittelalter, Hamburg, 1890, pp. 216 et seq.

The enormous development of miracle and fetich cures in the Church continued during century after century, and here probably lay the main causes of hostility between the Church on the one hand and the better sort of physicians on the other; namely, in the fact that the Church supposed herself in possession of something far better than scientific methods in medicine. Under the sway of this belief a natural and laudable veneration for the relics of Christian martyrs was developed more and more into pure fetichism.

Thus the water in which a single hair of a saint had been dipped was used as a purgative; water in which St. Remy's ring had been dipped cured fevers; wine in which the bones of a saint had been dipped cured lunacy; oil from a lamp burning before the tomb of St. Gall cured tumours; St. Valentine cured epilepsy; St. Christopher, throat diseases; St. Eutropius, dropsy; St. Ovid, deafness; St. Gervase, rheumatism; St.

Apollonia, toothache; St. Vitus, St. Anthony, and a mult.i.tude of other saints, the maladies which bear their names. Even as late as 1784 we find certain authorities in Bavaria ordering that any one bitten by a mad dog shall at once put up prayers at the shrine of St. Hubert, and not waste his time in any attempts at medical or surgical cure.(311) In the twelfth century we find a noted cure attempted by causing the invalid to drink water in which St. Bernard had washed his hands.

Flowers which had rested on the tomb of a saint, when steeped in water, were supposed to be especially efficacious in various diseases. The pulpit everywhere dwelt with unction on the reality of fetich cures, and among the choice stories collected by Archbishop Jacques de Vitry for the use of preachers was one which, judging from its frequent recurrence in monkish literature, must have sunk deep into the popular mind: "Two lazy beggars, one blind, the other lame, try to avoid the relics of St.

Martin, borne about in procession, so that they may not be healed and lose their claim to alms. The blind man takes the lame man on his shoulders to guide him, but they are caught in the crowd and healed against their will."(312)

(311) See Baas, p. 614; also Biedermann.

T. F. Crane, of Cornell University, London, 1890, pp. 52, 182.

Very important also throughout the Middle Ages were the medical virtues attributed to saliva. The use of this remedy had early Oriental sanction. It is clearly found in Egypt. Pliny devotes a considerable part of one of his chapters to it; Galen approved it; Vespasian, when he visited Alexandria, is said to have cured a blind man by applying saliva to his eves; but the great example impressed most forcibly upon the medieval mind was the use of it ascribed in the fourth Gospel to Jesus himself: thence it came not only into Church ceremonial, but largely into medical practice.(313)

(313) As to the use of saliva in medicine, see Story, Castle of St.

Angelo, and Other Essays, London, 1877, pp. 208 and elsewhere. For Pliny, Galen, and others, see the same, p. 211; see also the book of Tobit, chap. xi, 2-13. For the case of Vespasian, see Suetonius, Life of Vespasian; also Tacitus, Historiae, lib. iv, c. 81. For its use by St.

Francis Xavier, see Coleridge, Life and Letters of St. Francis Xavier, London, 1872.

As the theological atmosphere thickened, nearly every country had its long list of saints, each with a special power over some one organ or disease. The clergy, having great influence over the medical schools, conscientiously mixed this fetich medicine with the beginnings of science. In the tenth century, even at the School of Salerno, we find that the sick were cured not only by medicine, but by the relics of St.
