The last of the children born from Gaia and Uranus, the Hecatoncheires were strange creatures with 100 hands and 50 heads.  As with the Cyclopes, there were three brothers, Kottos, Briareos, and Gyges.  Hesiod says that they were creatures of great strength.  Imprisoned by Uranus and then by their brother Cronus in turn, they were freed by Zeus and aided him in the Titanomachy.  In return for their aid, Zeus appointed the Hecatoncheires as the guardians of Tartarus.
