Tiamat
In ancient Mesopotamian religion, Tiamat is the cosmic ocean that mates with Abzû, the groundwater, to produce the Bablyonian pantheon in the creation myth recorded in the Enūma Eliš ("When on High"). Tiamat is referred to as a woman, and has – at various points in the epic – a number of anthropomorphic features such as breasts and theriomorphic features such as a tail.
