Giacomo Berengario da Carpi (Jacobus Berengarius Carpensis, Jacopo Barigazzi, Giacomo Berengario da Carpi or simply Carpus) introduced iconography and independent anatomical observation into the teaching of anatomy. His Commentaria, a thick quarto of over 1000 pages, included 21 full-page woodcut text illustrations plus an architectural title-border, which included an image of a dissection scene. It was the first work since the time of Galen to display any considerable amount of anatomical information based upon personal investigation and observation. The Commentaria contains the first mention of the vermiform appendix, as well as the first good account of the thymus. The description of the male and female reproductive organs, the process of reproduction and the fetus were more extensive than any earlier account, and Berengario was the first to call attention to the greater proportional capacity of the female pelvis to the male pelvis. On fol. ccxxv Berengario gives the first authentic report of vaginal hysterectomy for prolapse. He describes two cases, one performed by himself in 1507 and the other by his father.
