Sir Palamedes
In the legend of King Arthur, Palamedes served as a Knight of the Round Table. He is a pagan from the Middle East who subsequently becomes a Christian, and because of his unrequited love for Iseult, he frequently fights with Tristan. Safir, Segwarides, and King Esclabor, Palamedes' father, also join the Round Table. After him, a romance was given the name Palamedes.
According to mythology, Sir Palamedes was not introduced in the Arthurian legends until 'Tristan en prose' or Prose Tristan was derived from Tristan and Iseult. According to legend, he and Tristan were the two men vying for Princess Iseult's hand in marriage in Ireland.
Iseult is delighted when Palomares puts on a strong show and triumphs over her. Tristan gave him the choice of stopping his collection of weapons or staying with Iseult, though. Later, he joins the Round Table and engages Tristan in an ongoing conflict that has no clear victor. He is also known as "Palamedes," the hero of another narrative that bears his name.
