Maleadus, Maliaduc, Meniadus, Minaduf
Tristanís father in the Prose Tristan and its adaptations. As such, he replaces Rivalin from earlier legends. The King of Lyonesse, Meliadus was considered one of the best knights in the world in his time.
He is a central character in the French Palamedes, in which he abducts the beautiful Queen of Scotland and has a son with her named Meliadus the Younger. As a result of this abduction, he went to war with Scotland and its allies, including Arthur. He lost and was imprisoned by Arthur at Camelot until Arthur needed his services to help against a Saxon invasion, led by Aliohan, whom Meliadus defeated in single combat. In La Tavola Ritonda, Meliadus refuses to submit to Arthurís rule and goes to war with the king, but surrenders when his ally, Lord Galehaut, yields.
Meliadus married Elyabel, Markís sister (although in Italian romance, Meliadus is Markís brother, the son of Felix). He was imprisoned in the Rock of the Cornishwoman by an enchantress at the same time that his wife gave birth to Tristan and died. He was rescued by Merlin.
He eventually re-married the daughter of King Hoel of Brittany (called Agia in La Tavola Ritonda), who tried to murder Tristan but ended up poisoning her own child by Meliadus. Meliadus spared her life at Tristanís request, but forever resented her. Meliadus was murdered by vassals of the Count of Norholt, or by his own kinsmen. Tristan fled Lyonesse to serve at King Faramon of Francesís court, but he later returned and avenged Meliadusís death. In Maloryís version, Meliadus is still alive some time after Tristanís return from Gaul.

Meliadus hated Guinevereís knights. He battled Sir Sagremor (Sagramore) on the Dry Island. After badly wounding Sir Dodinel, he was defeated by Lancelot, who forced Meliadus to go to Guinevere and apologize.
Arthur took Meliadus into his service, and Meliadus became a good friend to Lancelot. He participated in the Grail Quest. When the affair between Lancelot and Guinevere was exposed, Meliadus helped Lancelot rescue Guinevere from the stake; in the process, however, Meliadus was slain by Gaheris.
