Biography

Valeriano was born in Milan on 11 October 1586.Template:Sfn His father, Costantino Magni came from an ancient and noble Italian family.Template:Sfn At the age of two, Magni was taken by his parents from Italy to Prague.Template:Sfn As a young man, Magni entered the Capuchin Order in Prague. He spent his first years as lector,Template:Sfn and soon gained a great reputation as a preacher. In 1624 he was appointed Franciscan provincial of Bohemia and two years later he was named Prefect and Apostolic Vicar of the church’s mission to Poland, Bohemia, Hungary, and Germany.Template:Sfn He collaborated with various papal diplomats, particularly with the apostolic nuncios Pier Luigi Carafa in Cologne, Giovanni Battista Maria Pallotta, Ciriaco Rocci and Malatesta Baglioni in the Archduchy of Austria; Onorato Visconti, Mario Filonardi and Giovanni de Torres in the Polish–Lithuanian Commonwealth. His activity is documented by a large collection of letters preserved in various European archives.

Magni was greatly respected by Holy Roman Emperors Ferdinand II and Ferdinand III, as well as by King Władysław IV Vasa, who employed him on several diplomatic missions.Template:Sfn In July 1647 he performed a vacuum experiment (so-called Torricelli's experiment) before a distinguished audience at the Royal Castle in Warsaw.Template:Sfn The publication of the experiment aroused great controversy in 1640s.Template:Sfn The conversion of the Calvinist theologian Bartholomaeus Nigrinus, who was appointed confidential secretary to Władysław IV, was certainly a result of his influence, and it strengthened the Catholic party in Poland. Władysław IV solicited a cardinal’s hat for Magni, but the opposition of the Jesuits prevented his elevation to the cardinalate.Template:Sfn

Magni was very close to the Archbishop of Prague, Ernst Adalbert von Harrach. Landgrave Ernst of Hesse, who had been converted at Vienna on 6 January 1652, and who knew Father Valeriano, summoned Capuchins to St. Goar on the Rhine, and was present at the religious disputation between Valeriano and Peter Haberkorn of Giessen held at Burg Rheinfels in 1651.Template:Sfn Magni had a long-standing feud with the Jesuits, against whom he harbored a strong aversion. It was by his advice that pope Urban VIII abolished the Jesuitesses in 1631.Template:Sfn On the appearance of his pamphlet Contra imposturas Jesuitarum in 1659, he was summoned to appear before the papal court.Template:Sfn As he did not obey the summons he was arrested in Vienna at the instance of the nuncio, but Ferdinand III’s intervention secured his release.Template:Sfn

He then moved to Salzburg, where he remained for the rest of his life.Template:Sfn He died on 29 July 1661, aged 73.Template:Sfn

Selected works

Magni acquired great reputation in the seventeenth century by his polemical writings against the Protestants, and philosophical ones against Aristotelianism. Magni was a vehement anti-Aristotelian and an admirer of Galileo and Descartes.Template:Sfn He is referred to approvingly in the fifteenth of Pascal's Lettres provinciales and one of his Apologetical Letters may be found in the collection entitled Tuba magna, tom. II.Template:Sfn Cuthbert of Brighton considers Magni "the greatest and most vigorous of the Capuchin scholastic thinkers formed in the Bonaventuran tradition." His most important writings are:
