Another important surgeon of the West of Europe whose book has come down to us was John Yperman, who owes his name to the fact that he was a native of the town of Ypres (in Flemish Ypern) in Flanders. Yperman was sent by his fellow-townsmen to Paris in order to study surgery, apparently at the expense of the municipality, because they wanted to have a good surgeon in their town, and Paris seemed the best school at that time. Ypres, so familiar now as the scene of bloody battles, had become even before the war one of the less important cities even of Belgium, with less than 20,000 people. It was in the thirteenth century one of the greatest commercial cities of Europe, and probably had several hundred thousand inhabitants. The great hall of the Cloth Guild, one of the architectural triumphs of the time, and such an attraction for visitors to the town ever since (destroyed in the war) was built at this time, and is another tribute to the community feeling of the citizens, who determined upon the very sensible procedure of assuring the best possible surgery for themselves and fellow-citizens by having one of their townsmen specially educated for that purpose. Yperman's book on surgery was well known in his own time, but remained unprinted until about half a century ago (1854), when Carolus of Ghent issued an edition. Subsequent editions were issued by Broeckx, the Belgian historian (Antwerp, 1863), and by van Leersum (1913), who gathered some details of the great Flemish surgeon's life. After his return from Paris, Yperman obtained great renown, which maintains in the custom extant in that part of the country even yet of calling an expert surgeon "an Yperman." He is the author of two works in Flemish. One of these is a smaller compendium of internal medicine, which is very interesting, however, because it shows the many subjects that were occupying physicians' minds at that time. He treats of dropsy, rheumatism, under which occur the terms coryza and catarrh (the flowing diseases), icterus, phthisis (he calls the tuberculous, tysiken), apoplexy, epilepsy, frenzy, lethargy, fallen palate, cough, shortness of breath, lung abscess, hæmorrhage, blood-spitting, liver abscess, hardening of the spleen, affections of the kidney, bloody urine, diabetes, incontinence of urine, dysuria, strangury, gonorrhoea, and involuntary seminal emissions--all these terms are quoted directly from Pagel's account of his work.
