The New Student's Reference Work/Galahad, Sir

Galahad, Sir, in the Arthurian romances, the noblest and purest knight of the Round Table. He was the son of Sir Launcelot of King Arthur's court by marriage with Elaine, the fair daughter of King Pelles, and achieved the honor of winning the Holy Grail, in the quest of which his father and the other knights had failed. The meaning is that Sir Galahad, according to the legend, had been permitted by his sanctity to see the Holy Grail (Sangraal); that is, that he saw not by the eye of faith merely but with his bodily eyes, and touched with his hands the incarnate Savior, reproduced by the consecration of the elements of bread and wine. He therefore takes the "seat perilous" at the banquet of King Arthur and his knights, and becomes king of the Holy City. See Malory's romance of Morte d'Arthur and Tennyson's lyric of Sir Galahad, his Elaine and the Holy Grail in the Idylls of the King.

Sir Galahad—Watts

His strength was as the strength of ten,
Because his heart was pure.
