Hecatoncheires means "hundred handed". They were gigantic and had fifty heads and one hundred arms each of great strength. There were three of them: Briareus also called Aegaeon, Cottus, and Gyges also called Gyes. They were born to Gaea and Uranus. Their mutual hatered of Uranus caused him to force the Hecatoncheires back into Gaea's womb. This parcipatated Gaea's rebellion against Uranus. When Cronus came to power he imprisoned the Cyclopes in Tartarus. The were released by Zeus and fought with him against the Titans. They were able to hurl huge boulders as many as a hundred at a time against their opponents. One of them, Briareus, served as Zeus's bodygaurd.
