In Mesopotamian Religion (Sumerian, Assyrian, Akkadian and Babylonian), Tiamat is a primordial goddess of the ocean, mating with Abzû (the god of fresh water) to produce younger gods. She is the symbol of the chaos of primordial creation, depicted as a woman, she represents the beauty of the feminine, depicted as the glistening one. It is suggested that there are two parts to the Tiamat mythos, the first in which Tiamat is a creator goddess, through a "Sacred marriage" between salt and fresh water, peacefully creating the cosmos through successive generations. In the second "Chaoskampf" Tiamat is considered the monstrous embodiment of primordial chaos. 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; her husband, Apsu,(correctly) assuming they are planning to kill him and usurp his throne, later makes war upon them and is killed. Enraged, she, too, wars upon her husband's murderers, taking on the form of a massive sea dragon, she is then slain by Enki's son, the storm-god Marduk, but not before she had brought forth the monsters of the Mesopatmian pantheon, including the first dragons, whose bodies she filled with "poison instead of blood".Marduk then forms heavens and the earth from her divided body. Tiamat was later known as Thalattē (as a variant of thalassa, the Greek word for "sea") in the Hellenistic Babylonian writer Berossus' first volume of universal history. It is thought that the name of Tiamat was dropped in secondary translations of the original religious texts (written in the East Semitic Akkadian language) because some Akkadian copyists of Enûma Elish substituted the ordinary word for "sea" for Tiamat, since the two names had become essentially the same due to association.
