Pluto (mythology)

In ancient Roman religion and mythology, Pluto (Ancient Greek: Πλούτων, romanized: Ploútōn, Latin: Plūto or Plūton), also known as Dis Pater or Orcus, was the god of the dead and the king of the underworld. The name was originally an epithet or theonym for Hades in ancient Greek religion and mythology, although Pluto was more associated with wealth and never used as a synonym for the underworld itself, representing a more positive concept of the god who presides over the afterlife. He was the eldest son of Saturn (Cronus) and Ops (Rhea), as well as the brother of Jupiter (Zeus) and Neptune (Poseidon). Pluto later married Proserpina (Persephone) and shared many of Hades' attributes, such as the bident, the cap of invisibility, and the three-headed guard dog Cerberus.

While Pluto is commonly considered the Roman equivalent of Hades, the name Plouton was already used by the Greeks to designate Hades and was later adopted by the Romans for their god of the underworld, Dis Pater, which often means "Rich Father" and is perhaps a direct translation of Plouton. Pluto was also identified with the obscure god Orcus, name that the Romans adopted from the Etruscans and which, like Hades, was both for the god of the underworld and for the underworld as a place. On the other hand, Ploutōn was frequently conflated with Ploûtos, the Greek god of wealth, because mineral wealth was found underground and because, as a chthonic god, Pluto ruled the deep earth that contained the seeds needed for a bountiful harvest.

Pluto becomes the most common name for the classical ruler of the underworld in subsequent Western literature and other art forms, although in recent years it has lost relevance compared to Hades.
