Legendary king. Arthur is said to have valiantly defended his Celtic and Christian realm against pagan Anglo-Saxon invaders. His court at Camelot, with its famous "round table" of dedicated knights drawn from all over Europe, came to represent all the finest ideals of courtly love, of honour, of self-sacrificing service to God, country, and humanity, of knightly chivalry, and of mystical devotion to God's Holy Grail. Although there are references to Arthur by a variety of Medieval writers, the most complete account is Sir Thomas Malory's Le Morte d'Arthur, written in the 15th century nearly a thousand years after Arthur is supposed to have lived.
