Morcades, Morcads, Orcades
She is found in the First Continuation of Chrétien’s Perceval, in Les Enfances Gawain, and in Heinrich von dem Türlin’s Diu Crône. This would seem to indicate that she originated from the Orkneys, one of the realms of her husband, Lot. It appears to come from the Latin Orcades – ‘Orkneys’ – the land traditionally ruled by Gawain’s parents. The name became Morcades and then Morgause under the influence of Morgan le Fay.
Morcades had an affair with Lot, her page, and gave birth to Gawain, whom, in order to avoid a scandal, she gave up to a knight named Gawain the Brown. After Gawain had grown, he found his mother, grandmother (Igerne), and sisters living in Canguin Rock or Salie. Gawain freed them from the castle’s sorcery.
