URANUS, URANOS
Mythology of Greece and Rome
Was castrated by his son Chronos
This is the name of one of the primordial giants in the classical mythology of Rome and Greece. URANUS, also spelled OURANOS or OURANOUS, was the progeny of GAIA, with whom he produced the TITAINS, the HUNDRED HEADED GIANTS, and the monstrous CYCLPOPES. He so detested these beings that he enforced their stay in GAIA or, according to some versions, in the depths of TARTARUS. However, GAIA conspired with CRONOS to overthrow URANUS, and while he lay with GAIA, CRONOS castrated his father with a sickle. The blood from this act engendered the FURIES, and when it dropped over the sea, APHRODITE/VENUS was born from the foam.
