The Roman name for the underworld god associated with wealth, often equated with Pluto, was Dis Pater. The Latin name is commonly interpreted as “Rich Father” or “Father of Riches,” reflecting the god’s connection with the earth’s fertility and underground mineral wealth.
Dis Pater’s underworld role developed naturally from that association: precious metals and gems came from beneath the ground, which Romans also imagined as the realm of the dead. As Roman religion absorbed and reworked Greek ideas, Dis Pater was identified with Pluto, the Roman counterpart of Greek Hades, and was paired with Proserpina.
Dis Pater was sometimes shortened to Dis, and ancient writers could use the name in poetic references to death or the underworld. Pluto is a related name, not the best answer to this wording, while Orcus is another Roman underworld figure with overlapping associations. The gods’ identities were often blended in later literature, but Dis Pater is the specific wealth-linked title asked for here.
