Pelleas (Sir), lord of many isles, and noted for his great muscular strength.  He fell in love with lady Ettard, but the lady did not return his love.  Sir Gawain promised to advocate his cause with the lady, but played him false.  Sir Pelleas caught them in unseemly dalliance with each other, but forbore to kill them.  By the power of enchantment, the lady was made to dote on sir Pelleas; but the knight would have nothing to say to her, so she pined and died.  After the lady Ettard played him false, the Damsel of the Lake "rejoiced him, and they loved together during their whole lives."—Sir T. Malory, History of Prince Arthur, i. 79-82 (1470).
    Sir Pelleas must not be confounded with sir Pelles (q.v.). (Reader's Handbook of Famous Names in Fiction, &c., Brewer, 1899)
