Pluto

Pluto, in ancient mythology, the god of the lower world. He was a son of Saturn and Rhea, and was brother of Jupiter and Neptune, and when the world was divided among the three he obtained for his share " the darkness of night." His wife Persephone or Proserpine was violently carried from the upper world. (See Proserpine.) Of all the gods, he was the most hated by mortals, and his temples and statues were not numerous. In Homer he is always called Hades, but among the later Greek writers that term came generally to be applied to the abode of the dead itself. By the Roman poets Dis, Orcus, and Tartarus are used as synonymous with Pluto.

Plutus

Plutus (called also Pluton), in ancient mythology, the god of wealth. He was the son of Jasion and Ceres, and is said to have been blinded by Jupiter so that he might distribute his gifts without regard to merit, he having previously granted them to the good exclusively. When coming to mortals he is slow-footed and lame, when going from them swift-winged. He was usually represented as a boy with a cornucopia.
