... In his journeyings he came to Patelamunt, in the land of the Moors, where the queen, Belakane, was beset by enemies.  Then Gamuret came to her aid, and defeated her enemies; the queen wedded him, and he became king of Assagog and Zassamank.  But after a time he waxed weary, since there was no fighting to be done, and he also thought it ill that his wife should be a heathen, so he sailed away secretly, leaving a letter which told of his rank and lineage.  After his departure Belakane gave birth to a son, who was black and white even as his parents came of differing races, and she called her son's name Feirefis Angevin.
