The Augustinian friar Bartholomew of Urbino, as he is usually called after the town of his birth where he served as bishop during the last three years of his life (1347–1350), is best known for his still valuable Milleloquium veritatis S. Augustini. This monumental concordance contains some fifteen thousand excerpts from the writings of St. Augustine, grouped under about one thousand alphabetically arranged key words (for instance, abstinentia, ecclesia, fides, haeresis, iustitia, lex, praedestinatio, etc.) illustrating Augustine's doctrines on these topics. The work, for which Bartholomew's friend Petrarch furnished two poetical embellishments in the form of as many alternate sets of verses, was a success. Bearing witness to its wide diffusion and appreciation are over thirty MSS still extant in northern and central Europe (Austria, Belgium, Czechoslovakia, Germany, The Netherlands, and Poland), and about the same number in French, English, Italian, and Spanish libraries. It also went through five printings: Lyons 1555; Paris 1645, 1649, and 1672; Brescia 1734.
