Coeus, the Greek God and Titan was the son of Uranus and Gaea and were one of the four pillars that held the heavens up.
With his sister, Phoebe, Coeus fathered Leto and Asteria. Leto had children with Zeus and bore Artemis and Apollo.
Given that Phoebe symbolized prophetic wisdom just as Coeus represented rational intelligence, the couple may have possibly 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. Afterward, he and all his brothers were imprisoned in Tartarus by Zeus. Coeus, later overcome with madness, broke free from his bonds and attempted to escape his imprisonment but was repelled by Cerberus.
