Pluto

Pluto (Greek: Πλούτων, Ploutōn) was the ruler of the underworld in classical mythology. The earlier name for the god was Hades, which became more common as the name of the underworld as a place. In ancient Greek religion and myth, Pluto represents a more positive concept of the god who presides over the afterlife. Ploutōn was frequently conflated with Ploutos (Πλοῦτος, Plutus), a god of wealth, because mineral wealth was found underground, and because as a chthonic god Pluto ruled the deep earth that contained the seeds necessary for a bountiful harvest. The name Ploutōn came into widespread usage with the Eleusinian Mysteries, in which Pluto was venerated as a stern ruler but the loving husband of Persephone. The couple received souls in the afterlife, and are invoked together in religious inscriptions. Hades by contrast had few temples and religious practices associated with him, and is portrayed as the dark and violent abductor of Persephone.
