● The mythology of Androgynous Oannes is well known in the writings of Berossus, an important Babylonian historian. Oannes was a reformer and educator who came to Mesopotamia.
He introduced civilization, literature, science, and law to the local people. Oannes wrote and told the people the story of the creation of the land and the structure of the state.
The Sumerian legends and the legends of the antediluvian world do not mention only five cities. They also tell an extraordinary story of how their ancestors, who lived in “ancient times,” were visited by a brotherhood of dying and rising deity described as half-human, part-fish, “sent [by God] to teach the pre-Flood civilization of mankind and emerge themselves from the sea.
Their collection was known as the “Seven Sages” and their leader was called Androgynous Oannes.
Each was identified as an “advisor” to the antediluvian king and was noted for his expertise in governmental affairs and his skills as an architect, and engineer. ” – Graham Hancock, Underworld: The Mysterious Origins of Civilization
