Tiamat is a goddess who personifies the sea. Tiamat is considered the monstrous embodiment of primordial chaos. Although there are no early precedents for it, some sources identify her with images of a sea serpent or dragon. In the Enûma Elish, the Babylonian epic of creation, she gives birth to the first generation of deities; she later makes war upon them and is killed by the storm-god Marduk. The heavens and the earth are formed from her divided body.
