Ουρανος

Ouranos was the primordial god of the sky. The Greeks imagined the sky as a solid dome of brass, decorated with stars, whose edges descended to rest upon the outermost limits of the flat earth. Ouranos was the literal sky, just as his consort Gaia was the earth.
Ouranos and Gaia had twelve sons and six daughters. He locked the eldest of these - the giant Kyklopes and Hekatonkheires - away inside the belly of Earth. Gaia suffered immense pain and persuaded her Titan sons to rebel. Four of these positioned themselves at the corners of the world, ready to grasp their father as he descended to lie with Earth, while the fifth, Kronos, took his place in the centre and there castrated Ouranos with an adamantine sickle. The sky-god’s blood fell upon the earth, producing the avenging Erinyes and the Gigantes.
