His education completed, Bruno returned to Cologne, where he was most likely ordained a priest around 1055, and provided with a canonry at St. Cunibert's. In 1056 Bishop Gervais recalled him to Reims, where the following year he found himself head of the Episcopal school, which at the time included the direction of the schools and the oversight of all the educational establishments of the diocese. For eighteen years, from 1057 to 1075, he maintained the prestige which the school of Reims attained under its former masters, Remi of Auxerre, and others.
