Artist Britton LaRoche. In Welsh legend, King Arthur's sword is known as Caledfwlch... "Arthur's sword in his hand, with a design of two serpents on the golden hilt; when the sword was unsheathed what was seen from the mouths of the two serpents was like two flames of fire, so dreadful that it was not easy for anyone to look."
