Cannibalism

Cannibalism was an act that both revolted and intrigued the ancient readers. Due to this, there are multiple examples of cannibalism littered throughout ancient texts.

Examples
The Massagetai consider it the proper cultural norm to cut up their parents for cannibalistic tendencies. Also mentioned in Herodotus Book 1.

There is a link between cannibalism and poison in the body as nature strives to demonstrate how this person is not human.
