Sir Lancelot is a legendary character in the legend of King Arthur, and was a Knight of the Round Table. Sir Lancelot of the Lake was one of the most trusted knights of King Arthur's Round Table, but this soon changed when he fell in love with the king's wife, Queen Guinevere. He was raised by the Lady of the Lake, hence his title Lancelot Du Lac. Sir Lancelot was the only knight known to defeat King Arthur during a jousting match. He is also known briefly as the father of Sir Galahad, the greatest knight of all Camelot. Sir Galahad's mother is also possibly Elaine Of Configure. Lancelot's affair with Elaine later caused him and Guinevere to part ways.
