He had increasing differences with Pope Benedict XIV, though, such as over the assignment of Cardinal Passionei as pro-librarian and the pope's position in a conflict with Venice. Ultimately, these differences aggravated and led to his being sent back to his diocese in Brescia, where he died a few years later.
Quirini's writings include many works on the history of the Church, of Corfu, and of Brescia, as well as a five-volume edition of the correspondence of Cardinal Reginald Pole. In Brescia, he founded in 1745 the Biblioteca Queriniana, which still exists today[update], and he sponsored the German missions. He also financed the completion of the St. Hedwig Church in Berlin, which is today the cathedral of the archbishopric of Berlin.
