Lancelot

In the Arthurian legend, Sir Lancelot (Lancelot du Lac, or Lancelot of the Lake; also Launcelot) is one of the Knights of the Round Table. In most of the French prose romances and works, he is characterized as the greatest and most trusted of Arthur's knights, and plays a part in many of Arthur's victories – but Arthur's eventual downfall is also brought about in part by Lancelot, whose affair with Arthur's wife Guinevere destroys the unity of Arthur's court.

Lancelot is a popular character, and has been the subject of many poems, stories, plays, and films as a famous figure in the Arthurian cycle of romances.
