Galahad

Sir Galahad, sometimes referred to as Galeas or Galath, among other versions of his name, is a knight of King Arthur’s Round Table and one of the three achievers of the Holy Grail in Arthurian legend. He is the illegitimate son of Sir Lancelot and Elaine of Corbenic, and is renowned for his gallantry and purity as the most perfect of all knights. Emerging quite late in the medieval Arthurian tradition, Sir Galahad first appears in the Lancelot–Grail cycle, and his story is taken up in later works such as the Post-Vulgate Cycle and Sir Thomas Malory’s Le Morte d’Arthur. His name should not be mistaken with Galehaut, a different knight from Arthurian legend. (Wikipedia)
