In conclusion, we may say that, in the Middle Ages, once men had lifted themselves up from the condition into which they had been plunged by the incursions of the barbarians, there was nothing like the neglect of surgery which is sometimes said to have existed. Surgery had its normal development, and reached as high a stage as medicine in that beginning Renaissance, which is the characteristic feature of the twelfth, thirteenth, and fourteenth centuries. The traditions of a low state of surgery at this time are all false and founded on insufficient knowledge of the real conditions, which have been so clearly revealed to us by the investigation of original documents in the last twenty-five years. This was, in fact, one of the greatest periods in the history of surgery that the world has ever known. Whatever of difficulty in development surgery encountered was due not to any Church opposition, but to unfortunate conditions that arose in the practice of medicine. Professional jealousy and shortsightedness was the main element in it. Even this, however, did not prevent the very wonderful development of surgery that came {198} during the Middle Ages, and that made this department of human knowledge quite as progressive and successful as any other, in that marvelous period when the universities came into existence in the form which they have maintained ever since. {199} PAPAL PHYSICIANS. Most of what historical writers generally, who follow the old traditions of the medieval eclipse of medicine, have to say with regard to the supposed Papal opposition to the development of medical science, is founded on the assumption that men who believed in miracles and in the efficacy of prayer for the relief of disease could not possibly be interested to any serious degree in scientific medicine. As Dr. White says, "out of all these inquiries came inevitably that question whose logical answer was especially injurious to the development of medical science: why should men seek to build up scientific medicine and surgery, when relics, pilgrimages, and sacred observances, according to an overwhelming mass of concurrent testimony, have cured and are curing hosts of sick folk in all parts of Europe." He goes even farther than this, however, when he suggests that "it would be expecting too much from human nature to imagine that Pontiffs who derived large revenues from the sale of the Agnus Dei, or priests who derived both wealth and honors from cures wrought at shrines under their care, or lay dignitaries who had invested heavily in relics, should favor the development of any science which undermined their interests."
