Note 51 — Chapter IV
Reading edition
Nennius, a Breton monk of the ninth century, has left a brief Latin Chronicle in which is the earliest authentic account of the Legend of Arthur. Geoffrey of Monmouth, circa 1140, produced a Historia Britonum, avowedly based on a book brought from Britanny by Walter, Archdeacon of Oxford. No trace of this book, unless it be Nennius, can be found. See note at end of chapter.
