Panieri, Ferdinando an Italian theologian, was born at Pistoia Nov. 24, 1759. He was for some time professor of dogmatic theology in the seminary of his native town. He was favorable to Jansenism (q.v.), and assisted in the synod of 1786, where the principles of the Jansenists were discussed; but as he was in danger of persecution for his liberal stand, he afterwards addressed to the holy chair a complete retraction of his conduct. A canonicate was then given him, and the direction of the ecclesiastical conferences of the diocese in which he held the professorship. He died at Pistoia Jan. 27, 1822. His principal writing is Examen sur les peches qui se commettent dans les fetes et les plaisirs du siecle (Pistola, 1808-1813, 4 vols.).
