He is chiefly known for his continuation of the "Annals" of Cardinal Caesar Baronius and Odorico Raynaldi, which he brought down from the year 1566 to 1571.
His voluminous "Life of St. Peter Damian" (Vita Sancti Petri Damiani, Rome, 1702) was mercilessly but excessively criticized in an anonymous work entitled: "Sejani et Rufini dialogus de Laderchiana historia S. Petri Damiani" (Paris, 1705).
When he published his edition of the "Acts of the martyrdom of St. Crescus and companions" (Acta passionis SS.
Cresci et sociorum martyrum, Florence, 1707), the Servite G. Caspassi attacked their authenticity and trustworthiness in a letter to the Roman scholar Fontanini.
The ecclesiastical authorities seem to have put an end to the controversy; both works were placed on the Index Librorum Prohibitorum on 22 June 1712.
