1. 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. Theog. 134, 371, &c.; Apollod. i. 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. i. 8, xii. 132, Il. viii. 480; Hes. Theog. 1011; Ov. Met. xv. 406.)

2. Apollodorus (iii. 12. § 5) mentions a son of Priam of the name of Hyperion.
