In [[Mesopotamian religion]], '''Tiamat''' ({{lang-akk|{{cuneiform|7|𒀭𒋾𒊩𒆳}}}} {{transl|akk|<sup>[[dingir|D]]</sup><small>TI.AMAT</small>}} or {{Script/Cuneiform|7|𒀭𒌓𒌈}} {{transl|akk|<sup>[[dingir|D]]</sup><small>TAM.TUM</small>}}, {{lang-grc|Θαλάττη|Thaláttē}}) is a primordial [[water god|goddess of the sea]], mating with [[Abzu|Abzû]], the god of the [[Groundwater|groundwater]], to produce younger gods. She is the symbol of the chaos of primordial creation. She is referred to as a woman{{sfn|King|1902a|page=150|loc=line 122}} and described as "the glistening one".{{sfn|King|1902a|page=124|loc=line 36}} It is suggested that there are two parts to the Tiamat [[mythos]]. In the first, she is a creator goddess, through a [[Hieros gamos|sacred marriage]] between different waters, peacefully creating the cosmos through successive generations. In the second [[Chaoskampf]] Tiamat is considered the monstrous embodiment of [[primordial chaos]].<ref name="StephanieDalley">{{cite book |first=Stephanie |last=Dalley | author-link=Stephanie Dalley |title=Myths from Mesopotamia |publisher=[[Oxford University Press]] |year=1987 |pages=329 }}</ref> Some sources identify her with images of a [[sea serpent]] or [[dragon]].{{sfn|Jacobsen|1968|pp=104-108}}
In the ''[[Enûma Elish]]'', the [[Babylon]]ian [[Epic poetry|epic]] of [[Creation myth|creation]], Tiamat bears the first generation of deities; her husband, Apsu, correctly assuming that they are planning to kill him and usurp his throne, later makes war upon them and is killed. Enraged, she also wars upon her husband's murderers, bringing forth multitudes of monsters as offspring. She is then slain by [[Enki]]'s son, the storm-god [[Marduk]], but not before she had brought forth the monsters of the Mesopotamian pantheon, including the first dragons, whose bodies she filled with "poison instead of blood". Marduk then integrates elements of her body into the heavens and the earth.
