Professor Clifford Allbutt, in the address on the Historical Relations of Medicine and Surgery to the end of the Sixteenth Century, already quoted, has a passage in which, as an introduction to what he has to say about Galen, he sums up the history of anatomy from the return of the Popes from Avignon to Rome, which took place just about the beginning of the last quarter of the fourteenth century, down to the time of Vesalius. This expresses so well what I have been trying to say with regard to the gradual development that led up to the Golden Age of Anatomy and to Vesalius's work, that I quote it.

      "Meanwhile, however, the return of the Popes to Rome (1374) and the displacement of the Albucasis and Avicenna by the Greek texts renewed the shriveling body of medicine, and with the help of anatomy, Italian medicine awoke again; though until the days of Vesalius and Harvey the renascence came rather from men of letters than of medicine. The Arabs and Paris said: "Why dissect if you trust Galen? But the Italian physicians insisted on verification; and therefore back to Italy again the earnest and clear-sighted students flocked from all regions. Vesalius was a young man when he professed in Padua, yet, young or venerable, where but in Italy would he have won, I would not say renown, but even sufferance! If normal anatomy was not directly a reformer of medicine, by way of anatomy came morbid anatomy, as conceived by the genius of Benivieni, of Morgagni, and of Valsalva; the galenical or humoral doctrine of pathology was sapped, and soaring in excelsis for the essence of disease gave place to grubbing for its roots."

      A sketch of Vesalius's career will give the best possible idea of the influences at work in science during this Golden Age of anatomical discovery, and will at the same time serve to show better than anything else, how utterly unfounded is the opinion that there was opposition between religion, or theology and science, and above all medical science, at this time. On the other hand, it will demonstrate that the educational factors at work in Vesalius's time were not different from those of the preceding century, nor indeed from those that had existed for two or three centuries before his time; and though his magnificent original research introduced the new initiative which always comes after a genius has left his mark upon a scientific department, the spirit in which science was pursued after his time did not differ essentially from that which had prevailed before. He represents not a revolution in medical science, as has so often been said, though always with the purpose of demonstrating how much the so-called reformation accomplished in bringing about this great progress in anatomy, but only a striking epoch in that gradual evolution which had already advanced so far that his work was rendered easy and some such climax of progress as came in his time was inevitable.

      Vesalius's earlier education was received entirely in his native town of Louvain. There were certain preparatory schools in connection with the university at Louvain, and to one of these, called Paedagogium Castri because of the sign over the door, which was that of a fort, Vesalius was sent. Here he learned Latin and Greek and some Hebrew. How well he learned his Latin can be realized from the fact that at twenty-two he was ready to lecture in that language on anatomy in Italy. His knowledge of Greek can be estimated from the tradition that he could translate Galen at sight, and he was known to have corrected a number of errors in translations from that author made by preceding translators. To those who know the traditions of that time in the teaching of the classic languages along the Rhine and in the Low Countries, these accomplishments of Vesalius will not be surprising. They knew how to teach in those pre-reformation days, and probably Latin and Greek have never been better taught than by the Brethren of the Common Life, whose schools for nearly a hundred years had been open in the Low Countries and Rhenish Germany for the children of all classes, but especially of the poor. Other schools in the same region could scarcely fail to be uplifted by such educational traditions. Altogether, Vesalius spent some nine years in the Paedagogium.

      As illustrating how men will find what interests them in spite of supposed lack of opportunities, it may be said that from his earliest years Vesalius was noted for his tendency to be inquisitive with regard to natural objects, and while still a mere boy his anatomical curiosity manifested itself in a very practical way. He recalls himself in later years, that the bladders with which he learned to swim, and which were also used by the children of the time as play-toys for making all sorts of noises, became in his hands objects of anatomical investigation. Anatomy means the cutting up of things, and this Vesalius literally did with the bladders. He noted particularly that they were composed of layers and fibres of various kinds, and later on when he was studying the veins in human and animal bodies he was reminded of these early observations, and pointed out that the vein walls were made up of structures not unlike those, though more delicate, of which the bladders of his childhood days had proven to be composed.

      His preparatory studies over, Vesalius entered the University of Louvain, at that time one of the most important universities of Europe. At the end of the fifteenth and the beginning of the sixteenth century, Louvain probably had more students than any other university in Europe except that of Paris, and possibly Bologna. There are good grounds for saying that the number in attendance here during the first half of the sixteenth century was always in excess of 5,000. The university was especially famous for its teaching of jurisprudence and philology. The faculty of theology, however, was considered to be one of the strongest in Europe, and Louvain, as might be expected from its position in the heart of Catholic Belgium, was generally acknowledged to be one of the great intellectual bulwarks of Catholicity against the progress of Lutheranism in the Teutonic countries at this time. Vesalius's parents were, and his family always had been, ardent Catholics, so that, quite apart from his dwelling not far away, it was very natural that he should have been sent here. He seems to have spent five years in the university mainly engaged in the study of philosophy and philology, but also of the classics and languages so far as they were taught at that time.

      It may be noted as another instance in his life of how a student will find that which appeals to him even in the most unexpected sources, that Vesalius took special interest in certain treatises of Albertus Magnus and Michael Scotus, which treated of the human body in the vague, curious way of the medieval scholars, and yet with a precious amount of information, that this inquisitive youth eagerly drank in. More interesting for Vesalius himself were certain studies undertaken entirely independently of his university course. One of his biographers tells that he dissected small animals, rats and mice, and occasionally even dogs and cats, in his eagerness to learn the details of anatomy for himself and at first hand.

      After graduating at Louvain in philosophy and philology, Vesalius went to Paris to study medicine. At this time at Paris, Sylvius, after whom one of the most important fissures of the brain, the sylvian, is named, was not only teaching anatomy in a very interesting way, but was also providing opportunities for original research in anatomy in connection with his own investigations. The interest that his teaching excited may be gathered from the fact that over 400 students were in attendance at his lectures. Besides Sylvius, Günther of Andernach in Switzerland was also teaching in Paris, and with both of these distinguished professors Vesalius became intimately associated. His deep interest in the subject of anatomy would of itself be quite sufficient to attract the attention of professors, but he had besides the added advantage of being known as the descendant of a family which had occupied prominent posts as medical attendants to the greatest ruling family of Europe.

      It was at Paris, then, that Vesalius first was able to devote himself with the intense ardor of his character to the study of anatomy. Nothing less than original research at first hand would satisfy his ardent desire for information and his thirst for accurate knowledge. His practical temper of mind was demonstrated by a revolution that he worked in the method of doing dissections at the time. The dissections in Paris used to be performed by the barber-surgeons, as a rule rather ignorant men, who knew little of their work beyond the barest outline of the technics of dissection. Teachers in anatomy used to stand by and direct the operation and demonstrate the various parts. These teachers, however, considered it quite beneath them to use the knife themselves. The faultiness of this method can be readily understood. Vesalius began a new era in the history of anatomy by insisting on doing the dissections himself. It was not long, however, before he realized that Paris could not afford him such opportunities as he desired. Altogether he did not remain there more than a year, and then returned to the Low Countries.

      At Louvain he continued his anatomical work, finding it difficult enough to procure human material, but using such as might come to hand.
