Coeus

Coeus, or Koios, was one of the Titans, the giant sons and daughters of Uranus and Gaia. His Roman equivalent was Polus, the embodiment of the celestial axis around which the heavens revolve. The etymology of Coeus' name provided several scholars the theory that Coeus was also the Titan god of intellect, who represented the inquisitive mind.

Like most of the Titans, he played no active part in Greek religion--he appears only in lists of Titans--but was primarily important for his descendents. With his sister, Phoebe, Coeus fathered Leto and Asteria. Thought it is not explicitly mentioned, Lelantos was implied to be a son of Coeus, or at least Leto's male counterpart. Leo copulated with Zeus and bore Artemis and Apollo.

Given that Phoebe symbolized prophetic wisdom just as Coeus represented rational intelligence, the couple may have functioned together as the primal font of all knowledge in the cosmos. Along with the other Titans, Coeus was overthrown by Zeus and the other Olympians. After the Titan War, he and all his brothers were banished into Tartarus by Zeus. Coeus, later overcame with madness, broke free from his bonds and attempted to escape his imprisonment but was stopped by Cerberus.
