Mondeville is particularly interesting for the history of surgery because he himself ventured to trace some of the recent history of the development of his speciality. Following Galen's example, who had divided the physicians of the world into three sects, the Methodists, the Empirics, and the Rationalists, Mondeville divides modern surgery into three sects: First, that of the Salernitans, with Roger, Roland, and the Four Masters; second, that of William of Salicet, and Lanfranc; and third, that of Ugo da Lucca and his son Theodoric and their modern [_sic_] disciples. The characteristics of these three sects are in brief. The first limited patients' diet, used no stimulants, dilated all wounds and looked for union only after pus formation. The second allowed a liberal diet to weak patients, though not to the strong, but generally interfered with wounds too much. The third believed in a liberal diet, never dilated wounds, never inserted tents, and its members were extremely careful not to complicate wounds of the head by unwise interference. Almost needless to say, his critical discussion of the three schools is extremely interesting. Mondeville was himself a broadly educated scholar, who considered that the surgeon should know everything worth while knowing about medicine, for his work was greater than that of the physician. While he had high ideas, however, of the value of theoretic knowledge, he insisted above all on the value of practical training. He said, in his textbook on surgery, as to what the training of the surgeon should be:
