 As a monk in the monastery at Erfurt and as a temporary lecturer at Wittenberg, Luther’s education continued under his teachers Jodocus Trutfetter (1460–1519) and Bartholomaeus Arnoldi of Usingen (1465–1532), as he followed a theology curriculum dominated by Ockhamism, studying central texts such as Peter Lombard’s Sentences and commentaries on them by Gabriel Biel and Pierre d’Ailly, Aristotle’s works with Ockham’s commentaries, and major works by Augustine, while also lecturing on some of them. In 1512 Luther replaced Staupitz at the university in Wittenberg as professor of the Bible, a position he was to hold until his  death.[3]  Earlier in the same year, Luther made his only excursion beyond German lands, travelling to Rome on behalf of Staupitz; he was later to present this as an experience that began to turn him against the religious rituals and practices he found there, including that of indulgences.
