Palamedes (Arthurian legend)

Palamedes was originally a Saracen (Middle Eastern) knight, who was converted to Christianity. He loved Iseult, which made him enemies with Iseult's lover (but not her husband, King Mark of Ireland) Sir Tristan. He, along with Sirs Safir and Segwarides, was the son of Lord Eslabor of Babylon. When Sir Lancelot and Guinevere's affair was exposed, he and his brothers joined Lancelot in exile to France, where Sir Palamedes became Duke of Provence. He was killed by Sir Gawain, because he had killed King Mark, who had killed Sir Tristan (with Palamedes' spear).
