luminous writing." Pagel says, "Chauliac represents the summit of attainment in mediaeval {137} surgery, and he laid the foundation of that primacy in surgery which the French maintained down to the nineteenth century." Professor Clifford Allbutt says of Chauliac's treatise, "This great work I have studied carefully and not without prejudice; yet I cannot wonder that Fallopius compared the author with Hippocrates or that John Freind calls him the prince of surgeons. The book is rich, aphoristic, orderly and precise." In a word it has all the qualities that are usually said to be lacking in the work of mediaeval scientists, and it is a standing reproach to those who ignorantly have made so little of the work of these wonderful men of the olden time, who anticipated so many of the features of our modern medicine and surgery that we are prone to think of as representing climaxes in human progress, indications of a wonderful human evolution. Two other names of great professors of surgery deserve to be mentioned because they make it very clear that this wonderful development of surgery was not confined to France and Italy, but made itself felt all over Europe. One of these is John Ypermann, a surgeon of the early fourteenth century, of whom almost nothing was known until about twenty-five years ago, when the Belgian historian, Broeck, brought to light his works and gathered some details of his life. He was a pupil of Lanfranc, and at the end of the thirteenth century studied at Paris on a scholarship voted by his native town of Ypres, {138} which provided maintenance and tuition fees for him at the great French university expressly in order that he might become expert in surgery. We are likely to think of Ypres as an unimportant town, but it was one of the great industrial centres of Europe and one of the most populous, busy towns of Flanders in the Middle Ages, noted for its manufacture of linens and fine laces. The famous Cloth Hall, erected in the thirteenth century, one of the most beautiful architectural monuments in Europe, and one of the finest buildings of its kind in the world, was the result of the same spirit that sent Ypermann to Paris.
