Pallavicini, Niccolo-Maria an Italian theologian, was born at Genoa in 1621, and was related to the preceding. In 1638 he joined the Order of the Jesuits, and was finally made a professor of theology by queen Christina of Sweden. He was a great favorite at Rome, and was employed by the popes in several important undertakings. Innocent XI conferred the purple upon Pallavicini, and otherwise favored him. He died Dec. 15, 1672, at Rome. Among his numerous writings the following are noteworthy: Di Jesa della Provideniza divina conti-o i 'nemici' di ogni religione (Rome, 1799): — Difesa del pontificato Romano e della Chiesa, Cattolica (ibid. 1686, 3 vols. fol.), both able defences, especially the latter, which is by many considered the most consistent and skilful advocacy of papal supremacy. It is freely quoted by modern Romish apologists. See Sotwel, De Script. Soc. Jesu; Steinmetz, Hist. of the Jesuits (see Index in vol. 3).
