 Agrestes

Agrestes was, according to the 13th-century Arthurian Vulgate Cycle, a pagan king of Camelot in the time of Joseph of Arimathea.Though the "Lancelot" section of the cycle has him converted by Joseph himself, the "Estoire del Saint Graal" section, written after the Vulgate "Lancelot" as a prequel, states that Joseph's son Josephus converted him.
