That's so interesting, I had no idea. It strikes me that there were a lot of pig attacks in the middle ages.
Also this part is something I never thought about:
Overlooked by these interpretations is something that, as we increasingly remove animals from public view, becomes harder to appreciate: These people saw aspects of animal behavior that we don’t see anymore. In this sense, these seemingly odd trials have much to teach us about how fundamentally our relationship with animals has changed over time and how, more poignantly, we’ve lost the ability to empathize with them as sentient beings.
