In or about 1739, Facciolati undertook the continuation of Nicolò Comneno Papadopoli, who wrote a history of the University of Padua, carrying it on to his own day. Parts claimed by Papadopoli concerning Nicolaus Copernicus were later exposed as fraudulent by Carlo Malagola and Leopold Prowe. Facciolati was known overall Europe as one of the most enlightened and zealous teachers of the time; and among the many flattering invitations which he received, but always declined, was one from the king of Portugal, to accept the directorship of a college at Lisbon for the young nobility. He died in 1769. His history of the university was published in 1757, under the name Fasti Gymnasii Patavini.
