(Ὑπερίων), a Titan, a son of Uranus and Ge, and married to his sister Theia, or Euryphaessa, by whom he became the father of Helios, Selene, and Eos. (Hes. Th. 134, 371, &c.; Apollod. 1.1.3, 2.2.) Homer uses the name in a patronymic sense applied to Helios, so that it is equivalent to Hyperionion or Hyperionides; and Homer's example is imitated also by other poets. (Hom. Od. 1.8, 12.132, Il. 8.480; Hes. Th. 1011; Ov. Met. 15.406.) Apolldorus dorus (3.12.5) mentions a son of Priam of the name of Hyperion.
