titled Saggio intorno al luogo del seppellire, which focused on the issue of hygiene and burials near churches. Also in 1774 he received permission to leave the Piarists, and resumed using the name Scipione. He would, however, keep and use the title of "the priest" (l'abbé) for most of his life. By the turn of the decade, Piattoli found himself in a faction that was losing in the politics of Modena, and decided to move, giving up his professorship in 1782. Piattoli arrived in the Polish–Lithuanian Commonwealth that year, as a tutor for the sons of Piotr Potocki, a member of the magnate Potocki family. It was said in a contemporary account that his entire material wealth at that time was composed of a “sizable library”. Piattoli ended his service with the Potocki family around 1784 due to personal disagreements with Pelagia Potocka and Maria Radziwiłł. In the meantime, he became associated with the Lubomirski family—Izabela Lubomirska in particular—and through them befriended Stanisław Kostka Potocki and Grzegorz Piramowicz. Through Potocki and Piramowicz he became a member of the Society for Elementary Books in 1784. In the Society he was tasked with writing a textbook on the history of science. Around that time he was also active in Warsaw freemasonry. Piattoli traveled through Europe in the retinue of the Lubomirski family, including Izabela, and as a tutor of young Henryk Lubomirski. During that time he developed extensive contacts at various European courts in Courland, Austria (Vienna), Italy (Turin) and France (Paris). During his three-year stay in the Lubomirskis' Parisian residence, he was in touch with many important men of the Age of Enlightenment. He met—often through another Florentinian, Filippo Mazzei—Johann Wolfgang von Goethe, Thomas Jefferson, the Marquis de Lafayette, Luigi Landriani, Girolamo Lucchesini, and the Marquis de Condorcet. He also corresponded with J. G. Herder. In Poland, he developed close contacts with Ignacy Potocki and Julian Ursyn Niemcewicza. From 1787 he also tutored Adam Jerzy Czartoryski, later an important politician in the Russian Empire, on whom Piattoli would retain significant influence. Reformer and constitution drafter Piattoli developed contacts with notable figures on the Polish political scene, initially from the group opposed to the royal faction. By the end of his stay in Paris, he likely became a supporter of reforms in France and Poland, and begun taking his first serious steps in political activism, through the involvement in the Quattuowirat, a
