An essay in which he denied the identity of St Denis of Paris and St Denis the Areopagite (1641), caused a controversy. His Opera varia, where this essay is to be found, as well as a description in Latin verse of his voyage from Paris to Rome in 1590, have appeared in 5 vols (1696; new ed. Venice, 1728). To him is attributed Elogio di cardinale Baronio (1607).
