Doris was a nymph, one of the three thousand Oceanids born to the Titans Oceanus and Tethys. She married Nereus, the “Old Man of the Sea,” and gave birth to the fifty sea nymphs known as the Nereids.
Nereus, eldest son of Pontus and Gaia, was a Greek sea god and a much-revered “Old Man of the Sea.” With the Oceanid Doris he became the father of the fifty Nereids. In one story, Heracles wrestled Nereus.
