Sir Galahad, the illegitimate son of Lancelot and Elaine, is one of the knights of King Arthur’s Round Table. According to legend, his spiritual purity is so great that he outstrips even his father, destining him to achieve the Holy Grail. The values he embodies — courage, courtesy and chivalry — are also the ideals of the Old South which Quentin still holds dear. Also significant is that he is known as the knight of chastity: Tennyson, in his 1842 poem ‘Sir Galahad’, has him declare “I never felt the kiss of love, Nor maiden's hand in mine.”
