 Beyond the ruins of Dis are the frauds and corruptors, and finally the traitors.In ancient Roman mythology, Dis Pater ("Father Dis") is the ruler of the underworld and is named as such in the sixth book of Virgil's "Aeneid", one of the principal influences on Dante in his depiction of Hell (the god was also known as Pluto, a name not used by Virgil in the "Aeneid").The hero Aeneas enters the "desolate halls and vacant realm of Dis" with his guide, the Sibyl, who correspond in "The Divine Comedy" to "Dante" as the speaker of the poem and his guide, Virgil.
