Maddelena and Prancesca, daughters and scholars of Guglielmo Caccia. They assisted their father in his fresco works, and are the only women ever known to have practiced this branch of the art. In Montferrat they painted a number of cabinet pictures, and more altar-pieces than any other females. Orsola founded the convent of the Ursulines at Moncalvo, the chapel of which is decorated with some altar-pieces by her. There is also a Holy Family. Orsola died in 1678, and Francesca at the age of fifty-seven. See Spooner, Biog. Hist. of the Fine Arts, s.v.; Hoefer, Nouv. Biog. Generale,
