An excerpt from the article 26 facts about Hippopotamus
The first images of these animals were cave paintings in the mountains of the central Sahara. One of them depicts the moment when humans hunt a hippopotamus. In Egypt, these animals were considered threatening to humans until females' protectiveness over their offspring was noticed. Since then, the goddess Taweret, protector of pregnancy and childbirth, was depicted as a female with a hippopotamus head.
