Somewhat later Desiderius attached himself to the court of Pope Victor II at Florence. There he met two monks of the renowned Benedictine monastery of Monte Cassino, with whom he returned in 1055. He joined the community and was shortly afterwards appointed superior of the dependent house at Capua. In 1057 Pope Stephen IX, who had retained the abbacy of Monte Cassino, came to visit and at Christmas, believing himself to be dying, ordered the monks to elect a new abbot. Their choice fell on Desiderius. The pope recovered, and, desiring to retain the abbacy during his lifetime, appointed the abbot-designate his legate for Constantinople. It was at Bari, when about to sail for the East, that the news of the pope's death reached Desiderius. Having obtained a safe-conduct from Robert Guiscard, the Norman Count (later Duke) of Apulia, he returned to his monastery and was duly installed by Cardinal Humbert on Easter Day 1058.
