river called Ocean, which Homer described as winding its way in a circle round the edge of the earth. His parents were Uranus and Gaia.
The popular derivation of the name is from ocys, 'quick', 'swift' and nao, 'to flow', with a possible linguistic link-up with Latin aqua and Celtic uisge, both meaning 'water'. The actual origin of the word 'ocean' may lie in Sanskrit asayanas, 'lying over against'. It may be only a coincidence, however, that the names of the Aegean Sea and Ogygia (Calypso's island) also somewhat resemble the name.
