Helios, the god of the sun, mistakenly identified with Apollo, but of an older dynasty, was the brother of Selene (q.v.) and Eos (q.v.); a god of the brood of the Titans (q.v.), and the source of light to both gods and men; he rises from the bosom of Okeanos (q.v.) in the morning, and loses himself in his dark abyss every evening.
