"Both for his own great merits, as an original and independent observer, and as the master of Lanfranc, William Salicet (Guglielmo Salicetti of Piacenza, in Latin G. Placentinus de Saliceto--now Cadeo), was eminent among the great Italian physicians of the latter half of the Thirteenth Century. Now these great Italians were as distinguished in surgery as in medicine, and William was one of the protestants of the period against the division of surgery from inner medicine; a division which he regarded as a separation of medicine from intimate touch with nature. Like Lanfranc and the other great surgeons of the Italian tradition, and unlike Franco and Ambroise Paré, he had the advantage of the liberal university education of Italy; but, like Paré and Wurtz, he had large practical experience in hospital and on the battlefield. He practised first at Bologna, afterward in Verona. William fully recognised that surgery cannot be learned from books only. His Surgery contains many case histories, for he rightly opined that good notes of cases are the soundest foundation of good practice; and in this opinion and method Lanfranc followed him. William discovered that dropsy may be due to a '_durities renum_'; he substituted the knife for the Arabist abuse of the cautery; he investigated the causes of the failure of healing by first intention; he described the danger of wounds of the neck; he sutured divided nerves; he forwarded the diagnosis of { 84} suppurative disease of the hip, and he referred chancre and phagedaena to their real causes."
This paragraph sets forth some almost incredible anticipations of what are usually considered among the most modern phases of medicine and surgery. Perhaps the most surprising thing is the simple statement that Salicet recognized that surgery cannot be learned from books alone. His case histories are instructive even to the modern surgeon who reads them. His insistence on his students making careful notes of their cases as the soundest foundation of progress in surgery, is a direct contradiction of nearly everything that has been said in recent years about medieval medicine and especially the teaching of medicine. (See Appendix.)
William's great pupil, Lanfranc, followed him in this, and Lanfranc encouraged the practise at the University of Paris. There is a note-book of a student at the University of Paris, made toward the end of the Thirteenth Century, carefully preserved in the Museum of the University of Berlin. This notebook was kept during Lanfranc's teaching and contains some sketches of dissections, as well as some illustrations of operative procedures, as studied with that celebrated surgeon. The tradition of case histories continued at the University of Paris down to the beginning of modern surgery.
