Nereus is an ancient Greek water deity, who is not quite a Titan nor an Olympian, and He is the eldest son of Pontos, a divinity who is the sea personified. Nereus's name means "wet one."
The "old Man of the Sea" governed with a gentle hand & with great wisdom. Nereus, by some, is thought to have the gift of prophecy and a master shapeshifter.
Nereus & His wife Oceanid Doris, are the parents of 50 lovely daughters. These sea nymphs are known collectively as the Nereids, a name that originates from their father's name. A few of them played significant roles in mythology.....Thetis, Amphitrite, Psmathe & Galatea. It should be said that Nereus & His family lives in the sea.
Nereus has been depicted as an elderly man with a wooden staff. At times, he was painted with legs, at other times with a coiling fish tail. Unlike representations of other water deities, Nereus was always wearing a chiton, an article of clothing something like a toga.
