RAMUS
Just as Ramus had become an Eclectic in philosophy, so Fernel sought the best from various sources and different medical systems. Like Ramus, he cast off the yoke which authority had placed upon him; and proposed carefully planned principles which should lead to the discovery of truth. Like Ramus, Fernel presented his views in a clear style and in better order than was to be found in the writings of his predecessors. Like Ramus, he adopted the good and rejected the bad, regardless of whether it had been said by Aristotle, or by Galen, or by Hippocrates. Fernel was a reformer who stood for freedom of thought, which, up to his time, had suffered from the despotism of the scholastics. Although many of Fernel’s physiologic and pathologic ideas seem ridiculous when viewed in the light of modern knowledge, yet he deserves praise for daring to oppose ancient dogmas, and for pointing the road to progress. In breadth of view, Fernel was far superior to Sylvius and Guinterius.
The anatomical teaching in Paris in the early part of the sixteenth century was far from satisfactory. There was too much lecturing and theorizing from Galen’s texts, and too little of actual dissection. Vesalius, who was not backward in his criticisms, says that the dissections were made by ignorant barbers, and during the whole time that he was in Paris he never saw Guinterius use a knife upon a cadaver. Only at rare intervals was a human body brought into the amphitheatre, and then the dissection lasted less than three days. It comprised only a superficial study of the intestines and abdominal muscles; no other muscles were studied. The bones, veins, arteries and nerves were almost wholly ignored. The great lights of the Paris profession were totally unfit to give to the young Belgian what was his heart’s desire. They were ignorant and knew it not. It is not surprising that, on more than one occasion, Vesalius brushed the ignorant prosectors aside, took the knife into his own hands, and carried out the dissection in a systematic manner. His zeal and learning won the admiration of Guinterius who spoke of Vesalius and Servetus in loving terms;—“first Andreas Vesalius, a young man, by Hercules! of singular zeal in the study of anatomy; and second, Michael Villanovanus (Servetus), deeply imbued with learning of every kind, and behind none in his knowledge of the Galenic doctrine. With the aid of these two, I have examined the muscles, veins, arteries and nerves of the whole body, and demonstrated them to the students”.[19]
Vesalius must have had many blue days in Paris—days when he longed to have a free hand in dissection. A weaker character than his would have fitted peacefully into the established order of things, but not of such stuff was Andreas made. The difficulties which beset his path only stimulated him to work the harder; he firmly resolved to devote his energy, his talents and his life to anatomical study and teaching. He decided to secure the opportunity to dissect the human body and to rival the ancient Alexandrian professors who taught the subject. “Never”, he says, “would I have been able to accomplish my purpose in Paris, if I had not taken the work into my own hands”. The Book of Nature which Sylvius lauded, but kept his pupils from studying, was now opened by Vesalius. He dissected numerous dogs and studied the only part of human anatomy that was available, namely, the bones. In his search for materials for a skeleton he haunted the Cemetery of the Innocents. On one occasion, when he went to Montfauçon, the place where the bodies of executed criminals were deposited and bones were plentiful, Vesalius and his fellow-student were attacked by fierce dogs. For a time the young anatomist was in danger of leaving his own bones to the hungry scavengers. By such dangers he gained what the Paris professors could not supply. He became a master of the osseous system, so much so that, when blindfolded, he was able to name and describe any part of the skeleton which was placed in his hands. His talents were recognized by both professors and students; and at the third anatomy which he attended in Paris he was requested to take charge of the dissection. To the satisfaction of the students, as well as to the astonishment of the barbers, he made an elaborate dissection of the abdominal organs and of the muscles of the arm.

CHAPTER SIXTH
Vesalius Returns to Louvain
In the latter part of the year 1536, owing to the outbreak of the third Franco-German war, Vesalius returned to the University of Louvain. During this period he secured a human skeleton by secret means. Accompanied by his faithful friend, Regnier Gemma, known as a mathematician as well as a physician, Vesalius visited the gallows outside the walls of Louvain in order to search for bones. Here he found a skeleton which was held together simply by the ligaments and still possessed the origins and insertions of the muscles. Morley states that the body was that of “a noted robber, who, since he deserved more than ordinary hanging, had been chained to the top of a high stake and roasted alive. He had been roasted by a slow fire made of straw, that was kept burning at some distance below his feet. In that way there had been a dish cooked for the fowls of heaven, which was regarded by them as a special dainty. The sweet flesh of the delicately roasted thief they had preferred to any other; his bones, therefore, had been elaborately picked and there was left suspended on the stake a skeleton dissected out and cleaned by many beaks with rare precision. The dazzling skeleton, complete and clean, was lifted up on high before the eyes of the anatomist, who had been striving hitherto to piece together such a thing out of the bones of many people, gathered as occasion offered”.
