 This leads the narrator to then debate on medieval dream theory and the value of dreams.The poem then ends with the narrator consulting a variety of texts and stories, including a collection of "pryvé poyse" (l. 1344) detailing political abuses, a story of Genghis Khan (from the "Travels" of John Mandeville), a "raggeman rolle" (l. 1565) supposedly composed by The Devil, and a prophecy of Merlin.Due to some similarities with "Piers Plowman", it was suggested in the 19th century by W. W. Skeat that William Langland wrote the piece, but this theory is no longer accepted by the academic community.
