Tiamat

In Mesopotamian religion, Tiamat ( or , ) is the primordial sea, mating with Abzû (Apsu), the groundwater, to produce the gods in the Babylonian epic Enûma Elish, which translates as "when on high". She 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).

In the Enûma Elish, the Babylonian epic of creation, Tiamat bears the first generation of deities after mingling her waters with those of Apsu, her consort. The gods continue to reproduce, forming a noisy new mass of divine children. Apsu, driven to violence by the noise they make, seeks to destroy them and is killed. Enraged, Tiamat also wars upon those of her own and Apsu's children who killed her consort, bringing forth a series of monsters as weapons. She also takes a new consort, Qingu, and bestows on him the Tablet of Destinies, which represents legitimate divine rulership. She is ultimately defeated and slain by Enki's son, the storm-god Marduk, but not before she conjures forth monsters whose bodies she fills with "poison instead of blood". Marduk dismembers her, and then constructs and structures elements of the cosmos from Tiamat's body.
