Bishop (c.1036–1086), called The Younger to distinguish him from his uncle, Pope Alexander II, born Mantua, Italy; died there. Made Bishop of Lucca by his uncle, he accepted lay investiture from Henry IV of Germany, and in remorse became a Benedictine. Gregory VII ordered him to return to his see, where he made many reforms. He wrote against lay investiture and the anti-pope Guibert. Patron of Mantua. Because through his prayers was obtained the rout of the enemies of Gregory VII, he is represented before an army in confusion. Feast, 18 March.
