Hide this area Mythology

Uranus is according to greek mythology the embodiment of the sky or heavens, and known as the god of the sky. He was the first son of Gaia and he also became her husband.

Their children are the Cyclopes and Titans. Uranus was frightened of their great strength and the fact that they could easily depose him. He hid them away in Tartarus inside Gaia.
