Prosper of Aquitaine was a 5th-century Christian writer and a devoted follower of Augustine of Hippo. Born in Limoges, he later moved to Rome, where he served the papacy in a secretarial or notarial capacity. He is recognized as a significant theologian who vigorously defended Augustinian doctrines, particularly regarding the necessity of divine grace, against contemporary challengers. Beyond his theological contributions, he is noted for his historical work, serving as the first person to continue Jerome's universal chronicle.
