Influenced by Ovid and Claudian, Geoffrey Chaucer (1343–1400) developed the myth of Pluto and Proserpina (the Latin name of Persephone) in English literature. Like earlier medieval writers, Chaucer identifies Pluto's realm with Hell as a place of condemnation and torment, and describes it as "derk and lowe" ("dark and low"). But Pluto's major appearance in the works of Chaucer comes as a character in "The Merchant's Tale," where Pluto is identified as the "Kyng of Fayerye" (Fairy King). As in the anonymous romance "Sir Orfeo" ("ca." 1300), Pluto and Proserpina rule over a fantastical world that melds classical myth and fairyland. Chaucer has the couple engage in a comic that undermines the Christian imagery in the tale, which is Chaucer's most sexually explicit. The Scottish poet William Dunbar "ca." 1503 also described Pluto as a folkloric supernatural being, "the elrich incubus / in cloke of grene" ("the incubus in cloak of green"), who appears among the courtiers of Cupid.
