Pluto's identity was mostly derived from two unique entities: Hades, a Greek deity, and Plouton, the ruler of riches. It is likely that the identity of Pluto as a dis pater came through translation from one language to another; originally, the name may have had a different meaning. Hades was known as a protector of the dead in ancient Greece and Rome. He was also regarded as the judge of the afterlife who would decide each person's fate based on their actions while living. Thus, it made sense that people would associate Pluto with the underworld because it was there that he held court. However, according to some sources, Pluto was actually a sky god who taught men how to farm and build cities. The connection between Pluto and farming first appeared in the Hymn to Pluto. This poem was probably written around 700 BC by an unknown poet who may have been either Greek or Roman. In it, Pluto is praised for helping farmers grow crops and hunters find game so they could eat and drink well. This evidence shows that Pluto was seen as someone who helped people connect with nature and provide for themselves which matched his role as a ruler of the underworld. Another example used to prove that Pluto was a sky god is the story of Romulus and Remus.
