Probably the greatest of them was Guy de Chauliac, a Papal chamberlain, whom succeeding generations have honored with the title of Father of Surgery. His great text-book, the "Chirurgia Magna," was in common use for several centuries after his death, and is full of surgical teaching that we are prone to think much {369} more modern. He trephined the skull, opened the thorax, operated within the abdomen, declared that patients suffering from wounds of the intestines would die unless these were sewed up, operated often for hernia in an exaggerated Trendelenberg position, with the patient's head down on a board, but said that many more patients were operated upon for hernia "for the benefit of the surgeon's purse than for the good of the patient." His directions for the treatment of fractures and for taxis in hernia were followed for full four centuries after his time. No wonder that Pagel, the great German historian, declared that "Chauliac laid the foundation of that primacy in surgery which the French maintained down to the nineteenth century." Portal, in his "History of Surgery," declares that "Guy de Chauliac said nearly everything which modern surgeons say, and his work is of infinite price, but unfortunately too little read, too little pondered." Malgaigne declared "the 'Chirurgia Magna' a masterpiece of learned and luminous writing." Chauliac's [Footnote 24] personal character, however, is even more admirable than his surgical knowledge. He was at Avignon when the black death occurred and carried away one-half the population. He was one of the few physicians who had the {370} courage to stay. He tells us very simply that he did stay not because he had no fear, for he was dreadfully afraid, but he thought it his duty to stay. Toward the end of the epidemic, he caught the fever but survived it and has written a fine description of it. He was looked upon as the leader of surgery in his time, and this is his advice as to what the surgeon should be as given in the introductory chapter of his "Chirurgia Magna": "The surgeon should be learned, skilled, ingenious and of good morals; be bold in things that are sure, cautious in dangers; avoid evil cures and practices; be gracious to the sick, obliging to his colleagues, wise in his predictions; be chaste, sober, pitiful and merciful; not covetous nor extortionate of money; but let the recompense be moderate, according to the work, the means of the sick, the character of the issue or event and its dignity." No wonder that Malgaigne says of him: "Never since Hippocrates has medicine heard such language filled with so much nobility and so full of matter in so few words."
