The god of the underworld; counterpart of Greek Pluto.

God of death and the underworld.

In Roman mythology, Orcus was a god of the underworld, punisher of broken oaths, more equivalent to Pluto than to the Greek Hades, and later identified with Dis Pater. He was portrayed in paintings in Etruscan tombs as a hairy, bearded giant. A temple to Orcus may have existed on the Palatine Hill in Rome.
