OGYG′IA (Lat., from Gk. Ὠγυγίη, Ōgygiē). In Homer, the mythical island of Calypso, where she detained Odysseus. The word is originally an adjective, and describes the island as belonging to the sea-god Ogyges, whether identified with Oceanus or Poseidon. Later commentators tried to localize the island near Crete or Italy; in Homer its location is wholly indeterminate in the far West.
