Murad.
Son of Hadrama and Marsillus, King of Portugal, Castile, Aragon, Leon, and Valence, when those countries were held by the Moors. He was called Lord of the Lion, because he always led about a lion in silken fetters. When he carried defiance to Charlemagne at Fronsac, the lion fell in love with Aude the Fair; Murad chastised it, and the lion tore him to pieces. (Croquemitaine, vii.)
