Three of these former Jesuits especially attracted attention at this time in the domain of letters and science: Zaccaria, Tiraboschi, and Boscovich.
Francesco Antonio Zaccaria, whose name is sometimes written Zaccheria, was a Venetian who had entered the Austrian novitiate in 1731, when he was a boy of seventeen. He taught literature at Goritz, but was subsequently sent to Rome where he became very distinguished both for his eloquence and his marvellous encyclopedic knowledge. In 1751 he was appointed to succeed Muratori as the ducal librarian at Modena, though Cardinal Quirini had asked for him and the celebrated Count Crustiani subsequently tried to bring him to Mantua. His fame was so great that the most illustrious academies of Italy claimed his name for their registers. In Rome he became the literary historiographer of the Society, and had been so excellent an aid for Clement XIII in the fight against Gallicanism that the Pope assigned him a pension. That was just before the Suppression of the Society; when that event occurred he was deprived of his pension, and after frequently running the risk of being imprisoned in the Castle Sant' Angelo, he was ordered not to attempt to leave Rome. When Pius VI became Pope, Zaccaria's life became a little happier. His pension was restored and even increased; he was made Rector of the College of Clerical Nobles, and regained his old chair of ecclesiastical history in the Sapienza. He died in 1795 at the age of eighty-two. The "Biographie Universelle" says that, besides innumerable manuscripts, Zaccaria left one hundred and six printed books, the most important of which is the "Literary History of Italy" in 14 octavo volumes with supplements to volumes IV and V. His method of leading his readers through the literary labyrinth deserves no less praise than the penetration of his views, and the good taste of his criticism. Besides this literary work, he wrote on moral theology, scripture, canon law, history, numismatics, etc.
Girolamo Tiraboschi, who was born in Bergamo on December 28, 1731, went to the Jesuit school at Monza, and from there entered the Society. His first characteristic work, while teaching literature in Bergamo, was to re-edit the Latin-Italian dictionary of Mandosio. He made so many corrections that it was substantially a new work. When occupied as librarian in Milan, he discovered a set of valuable manuscripts about the suppressed Order of Humiliati. The publication of these MSS. filled up a gap in the annals of the Church, and made Tiraboschi's reputation in the world of letters. The Duke of Modena made him his librarian, the post formerly held by Zaccaria. Thanks to the munificence of the princes of Este, the library was a literary treasure house, and Tiraboschi conceived the idea of gathering up the riches around him and writing a good history of Italian literature; a task that seemed to be too much for one mind. The difficulty was increased by the jealousy of the various Italian states, so that an unbiased judgment about the merits of this army of writers called for a man with courage enough to shut his ears to the clamors of local prejudice. It supposed also a profound knowledge of ancient and modern literature, a sufficient acquaintance with the arts and sciences, and skill enough not to be overwhelmed by the mass of material he had to handle. It took him eleven years to complete the work.
The Spaniards were irritated by the "History" for they were blamed for having corrupted the literary taste of Italy, and three Spanish Jesuits attacked him fiercely on that score. Nevertheless, the Academy accepted a copy of the work in the most flattering terms. The Italians regarded it as a most complete history of their literature and a monument erected to the glory of their country. He was made a knight by the Duke and appointed counsellor of the principality. While he was engaged in this work, the Society was suppressed, and like Boscovich and Zaccaria, he did not live to see its resurrection. He died in Modena on June 3, 1794.
Ruggiero Giuseppe Boscovich was a Dalmatian from Ragusa, where he was born on May 18, 1711. He was a boy at the Jesuit college of that town and entered the Society at the early age of fourteen. He was sent to the Roman College, where his unusual literary and philosophical as well as mathematical abilities immediately attracted attention. He was able to take the place of his professor in mathematics while he was yet in his theological studies, and subsequently occupied the chair of mathematics with great distinction for a generation. His bent, however, was chiefly for astronomy, and every year he issued a treatise on one or another subject of that science. Among them may be mentioned: the "Sun spots" (1736); "The Transit of Mercury" (1737); "The Aurora Borealis" (1738); "Application of the Telescope in Astronomical Studies" (1739); "The Figure of the Earth" (1739); "The Motion of the Heavenly Bodies in an unresisting Medium" (1740); "Various effects of Gravity" (1741); "The Aberration of the Fixed Stars" (1742); and numberless others. Foreign and Italian academies, among them Bologna, Paris and London admitted him to membership. It was he who first suggested the massive pillars of the college church of St. Ignatius as the foundation of the Observatory in Rome; but the Suppression of the Society prevented him from carrying out the plan. When the great dome of St. Peter's began to crack, he allayed the general alarm by placing iron bands around it. His advice was sought for the draining of the Pontine Marshes; he surveyed the Papal States by order of Benedict XIV and induced the Pope to withdraw the obsolete decree in the Index against the Copernican system.
When King John V of Portugal asked for ten Jesuit Fathers to make an elaborate survey of Brazil, Boscovich offered himself for the arduous task, hoping thus to make a survey in Ecuador, so as to obtain data for the final solution of the problem of the figure of the earth which was then exciting much attention in England and France, but the Pope kept him for the survey of Italy, which Boscovich did, and in 1755 he published a large quarto volume describing the work. In 1748, he had already revived Leibnitz's system of dynamism in the composition of bodies, a view which his fellow-Jesuits generally rejected. When this volume was issued, the publisher added a list of Boscovich's previous works. They amounted to sixty-six and he soon added three more quartos on "The Elements of Mathematics." He even wrote Latin poetry, mostly eulogies of the Pope and distinguished men, and published five volumes of verse on "The Defects of the Sun and the Moon."
Boscovich's advice was sought as an engineer for damming the Lakes which were threatening the city of Lucca; and he acquitted himself so well, that he was made an honorary citizen and his expenses were subsequently paid for his scientific exploration in Italy, France and England. He settled a dispute between his native town and the King of France. He journeyed with the Venetian ambassador to Constantinople to complete his archæological studies, but that journey seriously injured his health. He then accepted the appointment of professor of mathematics at the University of Pavia and helped to found the Observatory of Brera in Milan which with that of the Collegio Romano is among the most prominent in Italy. The London Academy wanted to send him to California in 1769 to observe the transit of Venus, but the opposition to the Jesuits, which was four years later to lead to their suppression, caused the invitation to be withdrawn. Louis XV then called him to France where he was made director of optics for the Navy with a salary of 8,000 francs. He retained this position until 1783, that is ten years after the Society of Jesus had gone out of existence. He then went to Italy to publish five more books, and at the age of eighty-six retired to the monastery of the monks of Vallombroso. On account of his great ability, or rather on account of his being a Jesuit, he was bitterly assailed by Condorcet and d'Alembert and other infidels of France.
Bolgeni, who died in 1811, was made penitentiary by Pius VI in recognition of his services against Jansenism and Josephinism. Unfortunately, however, he advocated the acceptance of some scheme of Napoleon, for which Pope Pius VII deposed him from his office and called Father Muzzarelli from Parma to take his place. In 1809 when Pius VII was exiled, Muzzarelli went with him to Paris or at least followed soon after. His work on the "Right Use of Reason in Religion" ran up to eleven volumes, besides which he produced other books against Rousseau, and several pious treatises, like the "Month of May," which has been translated into many languages.
Possibly a certain number of missionaries remained with their neophytes because they were too remote to be reached. Others, who owed no allegiance to the king who ordered the expulsion, paid no attention to it, as the Englishman King, for instance, who was martyred in Siam after the Suppression; or the Irishman O'Reilly, who buried himself, in the forests of Guiana with his savages; Poirot was kept at the court of Pekin as the emperor's musician; and Benoit constructed fountains for the imperial gardens, invented a famous waterclock, which spouted water from the mouths of animals, two hours for each beast, thus running through the twenty-four hours of the day; he made astronomical observations, brought out copper-plate engravings of maps and so on, and finally died of apoplexy in 1774, one year after Clement XIV had suppressed the Society. Hallerstein, the imperial astronomer, was also there waiting for news of the coming disaster.
B. N. in "The Jesuits; their history and foundation" (II, 274) and Crétineau-Joly both declare that there were four of the proscribed Jesuits in the Etats généraux which was convened in Paris at the opening of the Revolution: Delfau, de Rozaven, San-Estavan and Allain. Of course, the Rozaven in this instance was not the John Rozaven so famous later on. In 1789 John was only eighteen years of age. In the session of February 19, 1790, the famous Abbé Grégoire, who afterwards became the Constitutional Bishop of Loir-et-Cher, startled the assembly by crying out, "Among the hundred thousand vexations of the old government, whose hand was so heavy on France, we must place the suppression of the celebrated Order of the Jesuits." The Deputy Lavie had also asked for justice in their behalf. The Protestant Barnave declared that "the first act of our new liberty should be to repair the injustices of despotism; and I, therefore, propose an amendment in favor of the Jesuits." "They have," said the next speaker, the Abbé de Montesquiou, "a right to your generosity. You will not refuse justice to that celebrated Society in whose colleges some of you have studied; whose wrongs we cannot understand, but whose sufferings were to be expected."
