Apsu

God of underground primeval waters. Mesopotamian (Babylonian-Akkadian). Derived from the Sumerian ABZU. In the Babylonian creation epic Enuma Elisˇ, Apsu is killed, while sleeping, by ENKI, who establishes his own abode above the deeps. Apsu’s death triggered the cosmic challenge between the forces of MARDUK and TIAMAT.
