Roman de Brut (meaning “Romance of Brut”) or “Brut” is a verse history of Britain by the poet Wace. It is based on Geoffrey of Monmouth’s Historia Regum Britanniae, and was probably begun around 1150 and finished in 1155.

Written in the Norman language, it consists of 14,866 lines. It was intended for a Norman audience interested in the legends and history of the new territories of the Anglo-Norman realm, covering the story of King Arthur and taking the history of Britain all the way back to the mythical Brutus of Troy.

The Brut was the most popular of Wace’s works and survives in more than 30 manuscripts or fragments. It was used by Layamon as the basis for his Brut and inspired Robert de Boron’s Merlin. It contained a number of significant elaborations of Geoffrey, including the first mention of King Arthur’s Round Table.
