Hades
In Greek mythology, Hades was the god of the underworld. But the underworld was often referred to by his name as well. His-oldest name was Hades, Aides or Aiidoneus, " the Unseen." He was the son of Cronus and Rhea, and brother of Zeus and Poseidon. Having deposed Cronus, the brothers cast lots for the kingdoms of the heaven, the sea, and the infernal regions.
