The heroine of Boccaccios prose romance called Il Filocopo. Her lover, Flors, is Boccaccio himself, and Blanchefleur was a young lady passionately beloved by him, the natural daughter of King Robert. The story of Blanchefleur and Flors is substantially the same as that of Dorigen and Aurelius by Chaucer, and that of Dianora and Ansaldo in the Decameron. (See DIANORA and DORIGEN.)
