Apsu (also spelled Abzu) is the primordial fresh water ocean that, according to Mesopotamian mythology, existed before the world. He is often depicted as a male deity and the source of all life. Apsu mingled with Tiamat, the salt water ocean, to create the first generation of gods. Think of Apsu as the original source code of the universe, the boundless potential from which everything emerged. He represents the deep, mysterious waters that precede creation.
