In Roth's life of Vesalius, which is usually considered one of our most authoritative medical historical works not only with regard to the details of Vesalius' life, but also in all that concerns anatomy about that time and for some centuries before, there is a passage quoted from Chauliac himself which shows how freely dissection was practised at the Italian universities in the fourteenth century. This passage deserves to be quoted at some length because there are even serious historians who still cite a Bull of Pope Boniface VIII, issued in 1300, forbidding the boiling and dismembering of bodies in order to transport them to long distances for burial in their own country, as being, either rightly or wrongly, interpreted as a prohibition of dissection and, therefore, preventing the development of anatomy. In the notes to his history of dissection during this period in Bologna Roth says: "Without doubt the passage in Guy de Chauliac which tells of having frequently seen dissections, must be considered as referring to Bologna. This passage runs as follows: 'My master Bertruccius conducted the dissection very often after the following manner: the dead body having been placed upon a bench, he used to make four lessons on it. In the first the nutritional portions were treated, because they are so likely to become putrefied. In the second, he demonstrated the spiritual members; in the third, the animate members; in the fourth, the extremities.'" (Roth, "Andreas Vesalius." Basel, 1896.)
