Montani, Giovanni-Giuseppe an Italian theologian, was born at Pesaro about 1685. He was descended from a noble family; joined the Society of Jesus at Rome, and taught in the schools of that order moral theology with so much success that persons came from distant parts to consult him. He revised and corrected a work of P. Pelizzari, made many additions to it, which he drew mostly from the decrees of the sacred congregation and from the bulls of Benedict XIV, and published it under the title Tractatus de Monialibus (Rome, 1755, 4to; 2d ed. Venice, 1761). He died in 1760. See Richard et Giraud, Bibliotheque Sacree.
