The personification of the vast ocean. As geography became more precise, Oceanus began to refer to the water outside of the Pillars of Heracles, or the Atlantic Ocean. He was the eldest of the Titans and a son of Uranus and Gaia. He was the father of all rivers by his sister Tethys. The couple also had the Oceanids which personified springs and smaller bodies of waters, like lakes and ponds.
