In Greek mythology, Iapetos (Greek: Ἰαπετός), also Iapetus or Japetus, was a Titan, the son of Ouranos (Uranus) and Gaia, and father of Atlas, Prometheus, Epimetheus, and Menoitios. He is a brother of Kronos, who ruled the world during the Golden Age. Iapetos is the Titan lord of the West. His name derives from the word iapto ("wound, pierce") and 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.
