Helaés of Limos, Helaes the Beautiful
Helaes was an orphan, the Countess of Limos, the sister of one Clapor le Riche and the niece of one Meleager le Rous, a sister or cousin of the Damoisele à la Harpe, and also unmarried and a determined lover of Sir Gawaine. Enlisting the aid of Oriolz the Dane (Oriel de Sorionde), she won a place in Gawaine’s bed.
It is likely that Helaes should be identifed with Malory’s sorceress Hellawes of the Castle Nigramous.
