In Greek mythology Hades was a god who was ruler of the underworld, the zone of the souls of the dead, or, in some versions, the greater part of the underworld not including the Elysian Fields. He was considered to be the brother of Zeus and husband of Persephone. The underworld, Tartaros, came to be called Hades after its ruler.
In Homer's Iliad, Agamemnon says of Hades that he is "the one who never pities or yields, and for that he is of all gods the one most hated by men".[1]
The Romans equated him to their god Pluto.
