Granddaughter of the Duke of Ferrara and heroine of the old romance Florice and Blanchefleur, which was popular throughout Europe during the sixteenth century, and is probably of Spanish origin. Blanchfleur and Florice (son of the King of Murcia) loved each other from infancy, and she gave him a magical ring. He was banished for his love, and Blanchfleur was eventually shipped to Alexandria to be sold as a slave. Florice, however, found her there, partly by aid of the mystic ring, and they were happily united. Versions of the Florice or Florio romance seem to have existed in the thirteenth century.
