CATTANEO, CARLO (1801-1869), Italian philosopher and republican, was the founder of the review Il Politecnico. He was the heart and soul of the Five Days of Milan (March 18-22, 1848), and bitterly opposed the hegemony of Piedmont in Italy. On the return of the Austrians he fled to Lugano, and there he wrote his Storia della Rivoluzione del 1848 and the Archivio trien nale delle cose d'Italia (3 vols., 1850-55). An uncompromising opponent of Cavour, he steadfastly refused to stand for election to the Italian parliament owing to his inability to take the oath of allegiance to the monarchy.
