The Titan Who Stayed Out of the War: Oceanus and the Great World River

Oceanus was the eldest of the twelve Titans, born to Uranus and Gaia, and in Hesiod's Theogony he is the personification of the great river the Greeks imagined encircling the entire flat disk of the inhabited world, the source from which every sea, river, spring and well ultimately flowed. He married his sister Tethys, and Hesiod credits the pair with three thousand sons, the river gods, and three thousand daughters, the Oceanid nymphs, a fertility on a cosmic scale matched by almost no other pairing in Greek genealogy. Unlike most of his fellow Titans, Oceanus took no part in the Titanomachy, the ten year war in which Zeus and the Olympians overthrew Cronus and the older gods. Some later sources explain this as neutrality rather than defeat, and Oceanus is depicted in the Iliad as a figure of primeval calm, once called by Homer the origin of the gods themselves, older and more fundamental than the Olympian order that came after him. He is regularly shown in art as a bearded, sometimes horned figure with crab claw horns rising from his head, often paired visually with Tethys, an image that long outlasted any organized worship of him and carried into Roman decorative art centuries after Greek religion had stopped addressing him directly in cult.
