 He is chiefly known for his continuation of the "Annals" of Cardinal Caesar Baronius and Odorico Raynaldus, which he brought down from the year 1566 to 1571.His contribution, though of some usefulness, is not sufficiently critical and is encumbered with numerous unimportant documents.It appeared in Rome (1728–1737), and extends from volume XXXV to volume XXXVII in the latest edition of Baronius (Bar-le-Duc, 1864–83).
