Bertruccio's master, Mondino, is hailed in the history of medicine as the father of dissection. His book on dissection was for the next three centuries in the hands of nearly every medical scholar in Europe who was trying to do good work in anatomy. It was not displaced until Vesalius came, the father of modern anatomy, who revolutionized the science in the Renaissance time. Mondino had devoted himself to the subject with unfailing ardor and enthusiasm, and from everywhere in Europe the students came to receive inspiration in his dissecting-room. Within a few years such was the enthusiasm for dissection aroused by him in Bologna that there were many legal prosecutions for body-snatching, the consequence doubtless of a regulation of the Medical Department of the University of Bologna, that if the students brought a body to any of their teachers he was bound to dissect it for them. Bertruccio, Mondino's disciple and successor, continued this great work, and now Chauliac, the third in the tradition, was to carry the Bolognese methods back to France, and his position as chamberlain to the Pope was to give them a wide vogue throughout the world. The great French surgeon's attitude toward anatomy and dissection can be judged from his famous expression that "the surgeon ignorant of anatomy carves the human body as a blind man carves wood." The whole subject of dissection at this time has been fully discussed in the first three chapters of my "Popes and Science," where those who are interested in the matter may follow it to their satisfaction.[23] After his Bologna experience Chauliac went to Paris. Evidently his indefatigable desire to know all that there was to be known would not be satisfied until he had spent some time at the great French university where Lanfranc, after having studied under William of Salicet in Italy, had gone to establish that tradition of French surgery which, carried on so well by Mondeville his great successor, was to maintain Frenchmen as the leading surgeons of the world until the nineteenth century (Pagel). Lanfranc, himself an Italian, had been exiled from his native country, apparently because of political troubles, but was welcomed at Paris because the faculty realized that they needed the inspiration of the Italian medical movement in surgery for the establishment of a good school of surgery in connection with the university. The teaching so well begun by Lanfranc was magnificently continued by Mondeville and Arnold of Villanova and their disciples. Chauliac was fortunate enough to come under the influence of Petrus de Argentaria, who was worthily maintaining the tradition of practical teaching in anatomy and surgery so well founded by his great predecessors of the thirteenth century. After this grand tour Chauliac was himself prepared to do work of the highest order, for he had been in touch with all that was best in the medicine and surgery of his time.
