Do you know of any diagrams of Galenic human anatomy?
The vast majority of examples of Galenic anatomy are text-based only. The closest that I know of would be the earliest works of Andreas Vesalius - while he ended up going on to criticize “Galen and his apes” (a
reference to the Barbary macaques that most of Galen’s anatomical
assumptions came from), human dissection was still technically illegal
when he was beginning his career in illustration and lecturing, and many
of his illustrations demonstrate his lack of fully-intact, undamaged
It’s likely that medieval European or Arabic illustrations featuring
any internal anatomy
had a large degree of Galenic influence. Magnus Hundt is one that comes to mind, and I’m sure there are others out there that I don’t know well.
