Late in life the emperor Charlemagne fell in love with a German girl. The barons at his court were extremely worried when they saw that the sovereign, wholly taken up with his amorous passion and unmindful of his regal dignity, was neglecting the affairs of state. When the girl suddenly died, the courtiers were greatly relieved—but not for long, because Charlemagne’s love did not die with her. The emperor had the embalmed carried to his bedchamber, where he refused to be parted from it. The Archbishop Turpin, alarmed by this macabre passion, suspected an enchantment and insisted on examining the corpse. Hidden under the dead girl’s tongue he found a ring with a precious stone set in it. As soon as the ring was in Turpin’s hands, Charlemagne fell in love with the archbishop and hurriedly had the girl buried. In order to escape the embarrassing situation, Turpin flung the ring into Lake Constance. Charlemagne thereupon fell in love with the lake and would not leave its shores.—Italo Calvino, Six Memos for the Next Millennium, quoting Barbey d’Aurevilly.
