a sea-god, son of Pontus and Ge, and father of the Nereids, the marine nymphs of the Mediterranean. His wife was Doris, the daughter of Oceanus. He is described as a wise and kindly deity, and especially skilled in divining the future. (Hor., lib. i., carm. 15.) His favourite haunt was the Ægean Sea, in which he lived with his daughters. The number of these nymphs is variously given as fifty or a hundred. (See Nymphs.)
