The first definite evidence in modern history for the existence of the practice of dissection is a famous law of the German Emperor, Frederick II., from the first half of the thirteenth century. This law was promulgated for the two Sicilies, that is, for Southern Italy and Sicily proper, very probably in the year 1240. It has often been vaguely referred to, but its actual significance can only be understood from the terms of the law itself, which has been literally translated by Von Töply in his Studien Zur Geschichte der Anatomie in Im Mittelalter. [Footnote 5] [Footnote 5: Deuticke Leipzig und Wien, 1893] The paragraph with regard to dissection runs as follows: "As an enactment that will surely prove beneficial to health, we decree that no surgeon will be allowed to practice, in case he has not a written testimonial, which he must present to the teachers in the medical faculty, that he has for at least a year applied himself to that department of medicine which is concerned with the teaching and practice of surgery, and that he has, above all, learned the anatomy of the human body in this manner, and that he is fully competent in this department {64} of medicine, without which neither surgery can be undertaken with success nor sufferers cured." [Footnote 6] [Footnote 6: The complete text of this law, which is a marvelous anticipation of all our efforts for the regulation of the practice of medicine down even to the present day, will be found in the appendix.] Such a regulation, as pointed out by Professor Pilcher in an article on the early history of dissection, [Footnote 7] and as we know by modern experience, does not come into force as a rule before the actual practice of what is prescribed, has been for some time the custom and its usefulness proved by the results attained. It seems very probable, then, that even at this early day the Emperor Frederick was only making into a law what had been at least a custom before this time. Lest anyone should think that this is a far-fetched assumption, certain other paragraphs of this law, which show very definitely the high degree to which the development of medical teaching had reached, must be recalled. Frederick declared that medicine could only be learned if there was a proper groundwork of logic. Only after three years devoted to logic, then, under which term is included the grammar and philosophy of an ordinary undergraduate course, could a man take up the study of medicine. After three years devoted to medicine, to which it is again specifically declared another year must be added if surgery were to be practiced, a man might be given his degree in medicine, but must spend a subsequent full year in the practical study of medicine under the supervision of an experienced physician.
