The first of this important group of north Italian surgeons who taught at these universities was Bruno of Longoburgo. While he was born in Calabria, and probably studied in Salerno, his work was done at Vicenza, Padua, and Verona. His text-book, the "Chirurgia Magna," dedicated to his friend Andrew of Piacenza, was completed at Padua in January, 1252. Gurlt notes that he is the first of the Italian surgeons who quotes, besides the Greeks, the Arabian writers on surgery. Eclecticism had definitely come into vogue to replace exclusive devotion to the Greek authors, and men were taking what was good wherever they found it. Gurlt tells us that Bruno owed much of what he wrote to his own experience and observation. He begins his work by a definition of surgery, _chirurgia_, tracing it to the Greek and emphasizing that it means handwork. He then declares that it is the last instrument of medicine to be used only when the other two instruments, diet and potions, have failed. He insists that surgeons must learn by seeing surgical operations and watching them long and diligently. They must be neither rash nor over bold and should be extremely cautious about operating. While he says that he does not object to a surgeon taking a glass of wine, the followers of this specialty must not drink to such an extent as to disturb their command over themselves, and they must not be habitual drinkers. While all that is necessary for their art cannot be learned out of books, they must not despise books however, for many things can be learned readily from books, even about the most difficult parts of surgery. Three things the surgeon has to do:--"to bring together separated parts, to separate those that have become abnormally united, and to extirpate what is superfluous." In his second chapter on healing he talks about healing by first and second intention. Wounds must be more carefully looked to in summer than in winter, because _putrefactio est major in aestate quam in hyeme_, putrefaction is greater in summer than in winter. For proper union care must be exercised to bring the wound edges accurately together and not allow hair, or oil, or dressings to come between them. In large wounds he considers stitching indispensable, and recommends for this a fine, square needle. The preferable suture material in his experience was silk or linen.
