Its students were exposed to a greater variety of influences than those of any other seat of learning in Germany. Its theology represented the more modern type of scholastic, the Scotist; its philosophy was the nominalist teaching of William of Occam, whose great disciple, Gabriel Biel (d. 1495), had been one of its most celebrated professors; the system of biblical interpretation, first introduced by Nicholas de Lyra(132) (d. 1340), had been long taught at Erfurt by a succession of able masters; Humanism had won an early entrance, and in Luther’s time the Erfurt circle of “Poets” was already famous. The strongly anti-clerical teaching of John of Wessel, who had lectured in Erfurt for fifteen years (1445-1460), had left its mark on the University, and was not forgotten. Hussite propagandists, Luther tells us, appeared from time to time, whispering among the students their strange, anti-clerical Christian socialism. While, as if by way of antidote, there came Papal Legates, whose magnificence bore witness to the might of the Roman Church. Luther had been sent to Erfurt to learn Law, and the Faculty of Philosophy gave the preliminary training required. The young student worked hard at the prescribed tasks. The Scholastic Philosophy, he said, left him little time for classical studies, and he attended none of the Humanist lectures. He found time, however, to read a good many Latin authors privately, and also to learn something of Greek. Virgil and Plautus were his favourite authors; Cicero also charmed him; he read Livy, Terence, and Horace. He seems also to have read a volume of selections from Propertius, Persius, Lucretius, Tibullus, Silvius Italicus, Statius, and Claudian. But he was never a member of the Humanist circle; he was too much in earnest about religious questions, and of too practical a turn of mind. The scanty accounts of Luther’s student days show that he was a hardworking, bright, sociable youth, and musical to the core. His companions called him “the Philosopher,” “the Musician,” and spoke of his lute-playing, of his singing, and of his ready power in debate. He took his various degrees in unusually short time. He was Bachelor in 1502, and Master in 1505. His father, proud of his son’s success, had sent him the costly present of a _Corpus Juris_. He may have begun to attend the lectures in the Faculty of Law, when he suddenly plunged into the Erfurt Convent of the Augustinian Eremites. The action was so sudden and unexpected, that contemporaries felt bound to give all manner of explanations, and these have been woven together into accounts which are legendary.(133) Luther himself has told us that he entered the monastery because he _doubted of himself_; that in his case the proverb was true, “Doubt makes a monk.” He also said that his resolve was a sudden one, because he knew that his decision would grieve his father and his mother.
