Iapetus

Iapetus, or Japetus, was a Titan, the son of Uranus and Gaia, and father of Atlas, Prometheus, Epimetheus, and Menoetius by Clymene or Asia.

Mythology
Iapetus is one Titan mentioned by Homer in the Iliad as being in Tartarus with Cronus. He is a brother of Cronus, who ruled the world during the Golden Age. His name usually refers to a spear, implying that Iapetus may have been regarded as a god of craftsmanship, though scholars mostly describe him as the god of mortality.

Iapetus's wife is normally a daughter of Oceanus and Tethys, named Clymene or Asia.

In Hesiod's Works and Days, Prometheus is addressed as "son of Iapetus" and no mother is named. However, in Hesiod's Theogony, Clymene is listed as Iapetus' wife and the mother of Prometheus.
