Ontzlake
Arthurian knight, brother of Damas, who rides with Arthur against Morgan le Fay.
Sir Ontzlake is a knight of the British Arthurian tradition, attested in Le Morte d'Arthur across three chapters of Book IV. He is the brother of Sir Damas and becomes entangled in the plot orchestrated by Morgan le Fay involving the enchanted sword Excalibur and the combat between Arthur and Accolon.
Le Morte d'Arthur presents Ontzlake as a knight of good character who is contrasted with his treacherous brother Damas. When called upon to provide a champion for trial by combat, Ontzlake is unable to fight himself, being "wounded a little to-fore through both his thighs with a spear" (Le Morte d'Arthur, Book IV, Chapter VIII). Sir Accolon, lodged with Ontzlake through Morgan le Fay's machinations, volunteers to fight in his stead, and "Sir Ontzlake was passing glad, and thanked Sir Accolon with all his heart" (Le Morte d'Arthur, Book IV, Chapter VIII).
After Arthur defeats Accolon and uncovers the plot, Arthur accords the two brothers: Ontzlake is praised as "a good knight, and full of prowess, and true and gentle in all your deeds" and invited to join Arthur's court (Le Morte d'Arthur, Book IV, Chapter XII). Ontzlake's response reveals his loyalty: "Alas, said Sir Ontzlake, that is great pity that ever so noble a man as ye are of your deeds and prowess, that any man or woman might find in their hearts to work any treason against you" (Le Morte d'Arthur, Book IV, Chapter XII). He subsequently rides with Arthur in pursuit of Morgan le Fay when she steals the scabbard of Excalibur (Le Morte d'Arthur, Book IV, Chapter XIV).
