Texts

Latin poem (139 hexametric lines) on Merlin and his prophecies, written by John of Cornwall in the middle of the 12th century, or somewhat later, in response to Geoffrey of Monmouth’s account of the same subject. In the introduction, John dedicates his work to his patron, Robert Warelwast (d. 1155), bishop of Exeter, or his succcessor Robert of Chichester (d. 1160?), and puts forward the claim that he is drawing on an independent Cornish source for his text. The text is accompanied by a prose commentary, notably including glosses in a variety of Brittonic, possibly Cornish, the origin and nature of which has been subject to some debate.

abstract:
Geoffrey of Monmouth in his History of the Kings of Britain is widely considered to have transgressed the historiographical canons of his time. The work provides a lengthy and detailed account of a prehistoric period for which no history in any currently accepted sense can be written. Among Geoffrey's greater departures from historical credibility is his championship of two mythical figures, Arthur and Merlin, both of whom are given a central place in his History. In this article, the author considers the evidence for the reception of Merlin's Prophecies and its implications for the reception of the history in which they were located. Besides reviewing the testimony of twelfth-century authors who used or criticised the Prophecies, she looks at commentaries on the Prophecies, both published and unpublished, written by contemporaries. She concludes that the Prophecies were attacked not because of any perceived historical inaccuracy but primarily because of political considerations. Indeed, the presence of Merlin's Prophecies at the heart of the History served to enhance its credibility and validity.
