Theologian; b. Ceva, in Piedmont, Nov. 9, 1734; d. Pavia, July 5, 1806. A Hermit of St. Augustine, he was a professor of theology at the University of Vienna. He published De rebus theologicis (3 v. Vienna 1774) and Theologia dogmatica in systema reducta (Vienna 1778). Though useful in their time, his writings are of little value today. He was considered sympathetic to Josephinism and was named bishop of Como in 1789. Though criticized as excessively submissive to the emperor, he was named bishop of Pavia (1792), where he courageously defended the Church's rights during the French invasion. He was elected a deputy to the assembly at Bologna in 1802.
