Virgil, probably working from an Alexandrian source, recognized three: Alecto or Alekto ("endless anger"), Megaera ("jealous rage"), and Tisiphone or Tilphousia ("vengeful destruction"), all of whom appear in the Aeneid. Dante Alighieri followed Virgil in depicting the same three-character triptych of Erinyes; in Canto IX of the Inferno they confront the poets at the gates of the city of Dis. Whilst the Erinyes were usually described as three maiden goddesses, the Erinys Telphousia was usually a by-name for the wrathful goddess Demeter, who was worshipped under the title of Erinys in the Arkadian town of Thelpousa.
