In ancient Mythologies, we see Emanation in the form of the birth of various Gods. The Babylonian Creation Epic, Enuma Elish ("When Skies Above"), begins with an empty abyss inhabited only by Tiamat and Apsu- the Mother and Father who represent the Divine Source. (In these primitive terms, Apsu represented the fresh waters of the rivers, and Tiamat the salt waters of the sea. These were the ultimate source of life as understood by the Mesopotamian people.) The Epic goes on with the generations spawned by these two Cosmic Beings; each generation better (or at least stronger and more grossly refined) than the one before:
Lahmu and Lahamu emerged, Their Names pronounced. As soon as They matured, were fully formed, Anshar and Kishar were born, surpassing them. They passed the days at length, They added to the years. Anu, Their first-born son, rivaled his Forefathers; Anshar made His son Anu like Himself, And Anu begot Nudimmud in His likeness. He, Nudimmud, was superior to His Forefathers; Profound of understanding, He was wise, was very strong at arms Mightier by far than Anshar His father's begetter, He had no rival among the Gods His peers.
