A knight of the Round Table in the Arthurian legends, usually Sir Dinadan. A satirist and one of the few wits of the Arthurian legends, Dinadan writes a lampoon against King Mark and plays pranks on the other knights during a tournament in which Lancelot takes part. In response, Lancelot appears with a dress over his armour, overpowers Dinadan, and carries him into a nearby forest, where he dresses him as a woman for punishment. Dinadan is later killed by Mordred. Commentators have not asserted a Celtic ancestry for him.
