Pietro Sforza Pallavicino (1607-1667). "Born and educated in Rome, Pallavicino entered the Church and governed Iesi, Orvieto, and Camerino before joining the Jesuits. A professor of philosophy and theology at the Collegio Romano, he wrote poems, a tragedy, and a work of literary criticism, Considerazioni sopra l'arte dello stile (1646). He also published a vindication of the Jesuits and, best-known of all his works, the Istoria del Concilio di Trento (1656-7), defending the Council from the criticisms of Paolo Surpi." - The Oxford Companion to Italian Literature.
