Author's Final Manuscript
Oxford Classical Dictionary in Oxford Research Encyclopedia of Classics
Depictions of the underworld, in ancient Greek and Roman textual and visual sources, differ significantly from source to source, but they all draw on a common pool of traditional mythic motifs. These motifs, such as the realm of Hades and its denizens, the rivers of the underworld, the paradise of the blessed dead, and the places of punishment for the wicked, are developed and transformed through all their uses throughout the ages, depending upon the aims of the author or artist depicting the underworld. Some sources explore the relation of the world of the living to that of the dead through descriptions of the location of the underworld and the difficulties of entering it. By contrast, discussions of the regions within the underworld and existence therein often relate to ideas of afterlife as a continuation of or compensation for life in the world above. All of these depictions made use of the same basic set of elements, adapting them in their own ways to describe the location of, the entering into, and the regions within the underworld.
