Oannes
Mesopotamian mythology
Oannes, in Mesopotamian mythology, an amphibious being who taught mankind wisdom. Oannes, as described by the Babylonian priest Berosus, had the form of a fish but with the head of a man under his fish’s head and under his fish’s tail the feet of a man. In the daytime he came up to the seashore of the Persian Gulf and instructed mankind in writing, the arts, and the sciences. Oannes was probably the emissary of Ea, god of the freshwater deep and of wisdom.
