Travelling from the university to his home town in 1482, he was surprised by a snowstorm and took refuge in the Benedictine abbey of Sponheim near Bad Kreuznach. He decided to stay and was elected abbot in 1483, at the age of twenty-one. He set out to transform the abbey from a neglected and undisciplined place into a centre of learning. In his time, the abbey library increased from around fifty items to more than two thousand. He often served as featured speaker and chapter secretary at the Bursfelde Congregation's annual chapter from 1492 to 1503, the annual meeting of reform-minded abbots. Trithemius also supervised the visits of the Congregation's abbeys.
