Jesuit historian and humanist who ranked among classic Italian writers.

Bartoli entered the Society of Jesus in 1623 and wrote the well-known and frequently translated L'uomo di lettere difeso ed emendato (1645; The Learned Man Defended and Reformed). In addition to writing a history of the Jesuits in Italian, Istoria della Compagnia di Gesù (1653–73), Bartoli was the biographer of such Jesuit saints as Ignatius Loyola, Francis Xavier, and Francis Borgia.
