His work De stilo Latinarum inscriptionum libri III, published in three volumes in 1781, which shows a rigorous method, a novelty and originality of approach, as well as a solid preparation, gave him his European fame and is considered a milestone in the development of epigraphy.

He successively taught grammar at Fermo, humanities at Ragusa, and oratory at the Roman College where he established an academy of archaeology at the Kircherian Museum.

After the suppression of the Society of Jesus (1773) he became librarian to Cardinal Albani and in 1791 was appointed to a provostship in his native town.

[3] In the town of Chiari, his birthplace, to which he afterwards withdrew, he founded an institution for the education of girls, reformed the entire school system, devoted his library to public use, and restored many buildings and churches.

When the Society of Jesus was re-established he again took his place in its ranks, and died in Chiari in January 1822, aged eighty-four.
