Pluto (Latin: "Plūtō"; , "") is 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 itself. In ancient Greek religion and mythology, Pluto represents a more positive concept of the god who presides over the afterlife. "Ploutōn" was frequently conflated with "Ploutos", 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 necessary for a bountiful harvest. The name "Ploutōn" came into widespread usage with the Eleusinian Mysteries, in which Pluto was venerated as both a stern ruler and a loving husband to Persephone. The couple received souls in the afterlife and are invoked together in religious inscriptions, being referred to as "Plouton" and as "Kore" respectively. Hades, by contrast, had few temples and religious practices associated with him, and he is portrayed as the dark and violent abductor of Persephone.
