After Henry was made Archbishop of Trier in 956, he summoned Wolfgang, who became a teacher in the cathedral school of Trier, and also labored for the reform of the archdiocese, despite the hostility with which his efforts were met. Wolfgang's residence at Trier greatly influenced his monastic and ascetic tendencies, as here he came into contact with the great reform monastery of the 10th century, St. Maximin's Abbey, Trier, where he made the acquaintance of Saint Romuald, the teacher of Saint Adalbert of Prague.
