For the slaying of Karl the Great's despicable son, Charlot, Huon, duke of Guienne, is condemned to go to Babylon (or Bagdad) and demand four molars and a tuft of the beard of the kalif after kissing the latter's daughter and slaying her intended. This feat is accomplished through the friendship of Oberon and the magic power of his horn, a blast of which causes all wicked persons to dance, and of a certain ring, which had been abstracted from its owner, Titania, and to which all the spirit world was subject. Commanded to go to the Pope at Rome before consummating marriage with the kalif's daughter, Huon yields to temptation and the couple are thrown on a desert isle by Oberon, who had deserted his Titania with the vow never to return to her unless a human couple should be found who were absolutely faithful, since she had championed the faithless girl wife of an aged dotard. About the invented quarrel of Oberon and his queen, Titania, is centred the whole conception of Wieland's poem. Thrown by the instrumentality of Titania into captivity in Tunis, Huon and Rezia withstand the first test of temptation and, reunited, return to Paris and reconcile Karl.[2]
