Dis Pater, or Dispater was a Roman god of the underworld, later subsumed by Pluto or Hades. Originally a chthonic god of riches, fertile agricultural land, and underground mineral wealth, he was later commonly equated with the Roman deities Pluto and Orcus, becoming an underworld deity. Dis Pater was commonly shortened to simply Dis. This name has since become an alternative name for the underworld or a part of the underworld, such as the Dis of The Divine Comedy.
