Haha no, not at all. Anatomical study was conducted exclusively on dead bodies. In rare cases, it was possible to obtain the body of someone who had just been executed, so it would still be warm. However, studying the living body was forbidden by the Church, which during the Renaissance had a much stronger influence in the Italian peninsula. There are a few recorded instances of studies on living bodies, but these were extremely rare and harshly punished

I didn't bother to search since I'm scared but damn if that is really how they check the anatomy of human back then? It's a nice read, I'm kinda sad that he wasn't treated like a lover but he got killed so all is well..
