Lanval

Lanval is one of the Lais of Marie de France. Written in Anglo-Norman, it tells the story of Lanval, a knight at King Arthur's court, who is overlooked by the king, wooed by a fairy lady, given all manner of gifts by her, and subsequently refuses the advances of Queen Guinevere. The plot is complicated by Lanval's promise not to reveal the identity of his mistress, which he breaks when Guinevere accuses him of having "no desire for women". Before Arthur, Guinevere accuses Lanval of shaming her, and Arthur, in an extended judicial scene, demands that he reveal his mistress. Despite the broken promise, the fairy lover eventually appears to justify Lanval, and to take him with her to Avalon. The tale was popular, and was adapted into English as Sir Landevale, Sir Launfal, and Sir Lambewell.

Lanval is one of Marie's 12-lai collection, and only one explicitly set in Arthur's court with reference to the Round Table and the isle of Avalon (although the lai Chevrefoil too can be classed as Arthurian material). It was composed after Geoffrey of Monmouth’s who wrote of King Arthur in History of the Kings of Britain (ca. 1136) and of Avalon in Life of Merlin (ca. 1150).

Marie's lays despite the fairy tale atmosphere all feature ordinary humans, except for Lanval which features an immortal "fairy mistress". Here too, she is not "particularly supernatural" in her described manners and guises. However, she is evidently from the Otherworld and able to confer everlasting life on her lover. Lanval is rescued from Arthur's judgment by his mistress, which reverses the traditional gender roles of the knight in shining armor and the damsel in distress—at the conclusion, Lanval leaps onto the back of his mistress's horse and they ride off to Avalon.
