Dis Pater

Dis Pater (; Latin:; genitive Ditis Patris, lit. the "Rich Patriarch"), otherwise known as Rex Infernus or Pluto, is a Roman god of the underworld. Dis was originally associated with fertile agricultural land and mineral wealth, and since those minerals came from underground, he was later equated with the chthonic deities Pluto (Hades) and Orcus.

Dis Pater's name was commonly shortened to Dis, and this name has since become an alternative name for the underworld or a part of the underworld, such as the City of Dis of Dante'sThe Divine Comedy, which comprises Lower Hell.
