Sam O'Nella's ancient Roman animals

Whilst perusing Youtube I found a video by the channel Sam O'Nella Academy. The video is titled "Exotic Animals in Ancient Rome". The video starts off  with Sam talking about the ancient medicine man Galen. Galen was known to do horrible experiments on various animals. One animal that he favored was the Barbary Ape because they were similar to people. Among other things, Galen would squish different parts of the apes' brains to make them go unconscious. Later in the video, Sam begins to talk about Venatios. These are shows put on in coliseums in which people would fight and kill all sorts of exotic creatures. The Roman Empire was able to acquire almost any animal within their borders, and back then there were no animal rights laws. Sometimes the opposite show would occur in which a criminal was executed via animal mauling. This was known as Damnation ad Bestia. I am glad that my miscellaneous knowledge consumption has reared Latin related facts.
