an Augustinian monk, born 1696, in Tuscany. He was called by the Grand- duke of Tuscany to the chair of theology at Pisa, where he died, May 26, 1766. His principal work is a course of theology, printed at Rome, from 1739 to 1745, in 8 vols. 4to, under the title De Theologicis Disciplinis (also Naples, 1776, 10 vols. 4to). He was charged with Jansenism, and, by order of the pope, printed, at the Vatican, in 1749, an apology, under the title Augustinianum systema de gratia, de iniqua Baianismi et Jansenismi erroris insimulatione vindicatum (2 vols. 4to). Against Archbishop Languet, who repeated the same charge, and denounced him to Pope Benedict XIV, he wrote the work, In Opusculum Inscriptum J. J. Languet, Judicium de operibus Theologicis Belleli et Berti, expostulatio (Leghorn, 1756). Berti also wrote an Ecclesiastical History (7 vols. 4to; afterward abridged, Naples, 1748); and a work on the life and writings of Augustine (De Rebus gestis S. Augustini, librisque ab eodem conscriptis, Venice, 1756). — Biographie Universelle. 4, 361.
