Klingsor

A powerful medieval sorcerer in Wolfram’s Parzival, formerly the Duke of Terre de Labour (probably Italy as its capital was Capua), nephew of Vergil of Naples (Vergilius; author of the Aeneid).

While a duke of Mantua, he fell in love with Iblis, the wife of King Ibert of Sicily. When Ibert discovered that his wife and Klingsor were having an affair, he had Klingsor castrated. Klingsor then started to hate the human kind, fled to Britain to heal and study the magical arts. His talents made him a startling necromancer, and he used his magic to create the enchanted Schastel Marveile (Castel of Marvels) in Terre Marveile (‘Land of Marvels’).
