The first of four cartoons designed and made for the window of a landing in the artist’s house in Rottingdean, Sussex. The windows (now in the V&A: C.623 to 626-1920) encapsulate the story of the Quest for the Sangreal (Holy Grail) and the failure of Sir Launcelot, depicted in this cartoon (because of his adultery with Guinevere), Sir Gawaiane, (because he fails to live up to courtly ideals) and Sir Galahad (because of his worldliness).
The cartoons were presented to Lady Leighton-Warren by the artist.
