Overview
In Greek mythology, Oceanus ( ; , also , , or ) was a Titan son of Uranus and Gaia, the husband of his sister the Titan Tethys, and the father of the river gods and the Oceanids, as well as being the great river which encircled the entire world.
Etymology
According to M. L. West, the etymology of Oceanus is "obscure" and "cannot be explained from Greek". The use by Pherecydes of Syros of the form for the name lends support for the name being a loanword. However, according to West, no "very convincing" foreign models have been found. A Semitic derivation has been suggested by several scholars, while R. S. P. Beekes has suggested a loanword from the Aegean Pre-Greek non-Indo-European substrate. Nevertheless, Michael Janda sees possible Indo-European connections.
Genealogy
Oceanus was the eldest of the Titan offspring of Uranus (Sky) and Gaia (Earth). Hesiod lists his Titan siblings as Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys, and Cronus. Oceanus married his sister Tethys, and was by her the father of numerous sons, the river gods and numerous daughters, the Oceanids.
