Stories of King Arthur and His Knights

The material for the Arthur stories came from many countries and from many different periods of history. Much of it is wholly fanciful, but the writers connected all the incidents directly or indirectly with the old Briton king of the fifth century, who was the model of knighthood, "without fear and without reproach."
Perhaps there was a real King Arthur, who led the Britons against the Saxon invaders of their land, who was killed by his traitor nephew, and who was buried at Glastonbury.
