Etymology[]
In Greek mythology, Oceanus (Ὠκεανός, Ōkeanós) was the Titan son of Uranus and Gaia. He was the father of the river gods and Oceanids, and believed by the ancient Greeks and Romans to be the divine personification of the ocean, depicted as an enormous river encircling the world. He has on occasion been depicted as having the lower body of a serpent.
