Anzu, or Sumerian “Thunderbird,” is often depicted with large wings. This 2500 B. C. modern clay impression comes from a cylinder seal in which second from right is Enki (Ea), the God of Wisdom and Water. [ Akkadian or Babylonian name in parenthesis.] The stylized streams of water with fish in them flow from his sides. Enki is most widely depicted as a kind of goat-fish, so the fact that he wears horns (also a sign of divinity) and is surrounded by fish is another clue that this is Enki.
