The Roman god of the underworld, equivalent to the Greek Hades, is Pluto. Pluto rules over the realm of the dead and is often associated with wealth due to the precious minerals found underground. In Roman mythology, he is depicted as a stern figure, overseeing souls after death. His domain is not only a place of darkness but also a symbol of the natural cycle of life and death. Pluto’s character embodies the complexities of the afterlife within Roman beliefs, blending fear and respect for the unknown.
