Through Mathematics, Astronomy and Rome

Born in the Republic of Venice, Grassi was a promising student of mathematics and the natural sciences, especially astronomy. He completed his studies at the Jesuit College in Polotsk, in the Russian Empire, in 1804 and was appointed rector of the Institute for Nobles. The following year, he was ordered to replace the last remaining Jesuit missionary in China; this began a five-year journey across Europe in which he was ultimately unable to secure passage to the distant country. He instead began teaching at Stonyhurst College in England.

Grassi was sent to the United States in 1810, where he became the superior of the Jesuits' Maryland Mission and the president of Georgetown College. For significantly improving its curriculum and public reputation, as well as obtaining its congressional charter, Grassi became known as Georgetown's "second founder". He returned to Rome in 1817 as Archbishop Leonard Neale's representative before the Congregation de Propaganda Fide. He later became the rector of the College of the Holy Martyrs in Turin and provincial superior of the Jesuits' Turin Province. Grassi became a close confidant of King Charles Felix of Sardinia and spent time in Naples as confessor to Charles Felix's widow, Queen Maria Cristina. He also intervened on behalf of Charles Albert to allow him to succeed Charles Felix on the throne. In 1835, Grassi moved to Rome as the rector of the Pontificio Collegio Urbano de Propaganda Fide, a school for missionaries, and was later named the Jesuit Superior General's assistant for Italy.

Early life and education

Giovanni Antonio Grassi was born on 10 September 1775 in Schilpario, Lombardy, in the Republic of Venice. He studied under the Somaschi Fathers, before going to the diocesan seminary of Bergamo, where he studied theology for two years and was ordained a priest. On 16 November 1799, Grassi entered the Society of Jesus, which had been officially suppressed by the pope since 1773. He proceeded to the Jesuit novitiate in Colorno, on 21 November 1799, becoming one of the novitiate's first students.

Due to the nearly worldwide suppression of the Jesuit order, the novices at Colorno were allowed only to pronounce their simple vows. Because Empress Catherine the Great had declined to suppress the Jesuits, the order fled Western Europe and survived in the Russian Empire, and Polotsk (in present-day Belarus) became the order's center. Grassi went to the Jesuit College in Polotsk in 1801 to complete his priestly education, while the master of novices of the Colorno novitiate, Joseph Pignatelli, assured him that he would eventually return to Italy. Grassi was an excellent student in the natural sciences, and he completed his theological studies at the college in Polotsk in 1804. He then became the rector of the college's Institute for Nobles and a teacher of higher mathematics.

European voyage

Upon completing his education, Grassi began preparing for an assignment to minister to Armenians in Astrakhan, and was studying Armenian. He and two others were then summoned to Saint Petersburg by Gabriel Gruber, the Jesuit Superior General. On their arrival on 19 January 1805, Gruber informed them that they would be sent to Peking to replace the one remaining Jesuit missionary in China, Louis Antoine de Poirot. The Superior General determined that it would be preferable for the missionaries to travel by sea, rather than overland with a departing Russian delegation.

The General outfitted them with new vestments and chalices for celebrating Mass, mathematical and scientific instruments, medicines, furs for the winter, and gifts for the people. The trio departed by sled for Sweden, intending to go to London, where the Superior General had arranged for a ship to take them to Canton. Shortly after departing, Grassi and two others fell ill and were attended by a doctor for ten days in a small town on the Russian–Swedish border. They eventually reached Stockholm, Sweden, on 22 March 1805, where the Russian minister to Sweden informed them that the British would not permit them to sail from London. Therefore, the party instead went to Copenhagen, but discovered that there were no ships that could take them to Canton, and spent a month in Copenhagen waiting for the next ship to take them to London. The party reached London on 25 May, but found no ships that would take them to China. Lord George Macartney, the former British ambassador to China, failed to convince the directors of the East India Company to allow the Jesuits to travel on their vessels.

The party set sail for Lisbon, Portugal, where they hoped to secure passage to Macau. Their journey was delayed by a stop in Cork, Ireland, and they eventually arrived in Lisbon on 28 September 1805. The apostolic nuncio to Portugal informed them that due to the Portuguese persecution of the Jesuits under the Marquis of Pombal, they would not be permitted to board a Portuguese vessel without written approval from the pope. Meanwhile, Grassi studied astronomy under Count Damoiseau de Montfort. In March 1806, the three were informed that the Congregation de Propaganda Fide in Rome had become uneasy about their mission to China. Realizing that they would be in Portugal for considerably longer, the party began studying at the University of Coimbra for two months. Grassi also started tutoring the eldest son of Count Arcos in mathematics.

Due to an escalation of the persecution of Christians in China, the Superior General decided that he would no longer permit their mission. On 23 September 1807, he ordered them to go to Stonyhurst College in Lancashire, England, and await further instruction. Their vessel had to circumvent the French fleet invading Portugal, causing it to run out of food and almost run out of water. They finally reached Liverpool and then Stonyhurst College on 21 December 1807. At the college, Grassi taught Italian and Latin, while studying calculus and astronomy. He also studied mathematics and astronomy at the Royal Institution in London.
