He entered the Order of Benedictines in the monastery of Cluny. His uncle Urban II elevated him to the cardinalate and named him Cardinal-Bishop of Ostia ca. 1095. He participated in the papal election, 1099 and was a principal consecrator of Pope Paschalis II. He attended the council of Melfi in October 1100.
