Abbot of Cluny from 994. Under him the number of Cluniac houses increased and the order was strengthened by his plan of centralization, whereby most of the reformed monasteries were made directly dependent on Cluny. He was esteemed by Popes and Emperors, and the ‘Truce of God’ for S. France and Italy was largely his work. He introduced the commemoration of All Souls' Day (2 Nov.), which soon spread from Cluny to the whole W. Church. Feast day, 2 Jan. (among the Benedictines, 11 May).
