Bellarion the Fortunate, published in 1926, is an historical novel by Rafael Sabatini. Set at the beginning of the 15th century in northern Italy, it takes place first in the Marquessate of Montferrat and later in the Duchy of Milan. Most of its characters, including Gian Galeazzo Visconti, Gian Maria Visconti, Facino Cane, Filippo Maria Visconti, and Francesco Bussone da Carmagnola, were real historical figures; the scheming title character is the notable exception.
