The teachers in late twelfth-century Salerno were the first to introduce animal dissections into their courses. The first teaching involving a human body was carried out by Mondimo dei Liuzzi in Bologna around 1315. The practise of dissection was as much a spectacle as a lesson. The professor would dress in long robes, sit in a high chair and read out passages from the works of Galen, while an assistant pointed to the organs and a surgeon dissected the body.
