The New International Encyclopædia/Ogyges

OGY′GES, or OGYGUS (Lat., from Gk. Ὠγύγης, Ōgygēs, Ὤγυγος, Ōgygos). In Theban legend, one of the early kings of Bœotia, the son or grandson of Poseidon. In his reign a great flood took place in Bœotia, which destroyed cities on Lake Copais. His name was borne by one of the seven gates of Thebes, near which his grave was said to be. Later systematizing chronicles introduced Ogyges to Athenian legend, as King of Eleusis or even first King of Athens, while others transferred him to Egyptian Thebes. Whatever the origin of the name, there is much to show that Ogyges was originally the name in Bœotia of a sea-god like Poseidon.
