Bleoberis

Bleoberis is a literary persona that appears throughout medieval Arthurian romances rather than a mythic origin figure; onomastic evidence links the name to a 12th-century Welsh/Breton storyteller (Bledhericus / Maistre Blihis, possibly Bledri ap Cydifor), from which the knightly name migrated into vernacular manuscript traditions and narrative cycles.

Sources give no consistent physical description; Bleoberis is presented as a knight (Sir Bleoberis) and therefore is implicitly clothed in the martial accoutrements of a medieval knight (arms, armor, horse) but no specific heraldry, coloration, or bodily traits are described in the surveyed texts.

Bleoberis is depicted as an accomplished and ubiquitous martial and political actor: he fights for Arthur in campaigns (Bedegraine, Cameliard, against King Claudas), participates in the Grail Quest in Vulgate/Post-Vulgate material and the Prose Tristan, is made Duke of Poitiers by Lancelot in Vulgate tradition, leads forces in Lancelot's war against Arthur and Gawain, destroys Mordred's corpse and builds the Tower of the Dead in Post-Vulgate Mort Artu, kills Arthur the Less in self-defence in one episode, buries Lancelot at Joyous Gard, and later retires to monastic life and undertakes pilgrimage and crusade.
