Medieval hero and unlucky lover, King Arthur has been a non-stop rerun since the 6th century. Arthur’s mythology has been molded by dozens of writers of the centuries, best defined in 1485 with Thomas Malory’s Morte D’Arthur. Merlin, Morgan Le Fay, and the sword Excalibur have spread their public domain web on the vastness of fantasy literature, from Broadway musicals to Dr. Doom’s girlfriend to a bizarre cadre of European mutant super heroes.
