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 manuscripts, 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 passed it on to future generations.(304)

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 Cassino, prepared two manuscript 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 multitude 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 participation of ecclesiastics in the science and art of medicine was effectually prevented.(305)

monastic authorities against medicine and surgery, see Sprengel, Baas,

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 multitudes 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.
