"Plouton" was one of several euphemistic names for Hades, described in the "Iliad" as the god most hateful to mortals. Plato says that people prefer the name "Plouton", "giver of wealth," because the name of Hades is fear-provoking. The name was understood as referring to "the boundless riches of the earth, both the crops on its surface—he was originally a god of the land—and the mines hidden within it." What is sometimes taken as "confusion" of the two gods "Plouton" and "Ploutos" ("Wealth") held or acquired a theological significance in antiquity. As a lord of abundance or riches, Pluto expresses the aspect of the underworld god that was positive, symbolized in art by the "horn of plenty" (cornucopia), by means of which "Plouton" is distinguished from the gloomier Hades.
