Muzzarelli, Alphonso an Italian theologian, was born in 1749, and was educated at the college at Prato. He was then ordained, and entered the Order of Jesus, but was compelled to leave it five years after, as he was appointed canon at Ferrara; he was afterwards director of the college at Parma, and finally was called by pope Pius VI to Rome to take the position as thelologiau of the Poenitentiaria. He published while there several works against the irreligiousness of his time. He was in 1809 transported to Paris by the French, on account of his opposition to the Bonapartists, and there he died in 1815. His most important works are, 11 buon uso della Logica in materia della Religione, transl. into French and Latin: — L'Emilio disingannato contra Rousseau: — Influenza de' Romani Pontefici nel governo di Roma avanti Curlo Magno: — Memorie del Giaicobinismo: — dissertationes selectae, de auctoritate Romani Pontificis in Conciliis Generalibus, etc.
