Anselm ST., born at Mantua, of noble parents, was raised in 1061 to the bishopric. OF LUCCA, by pope Alexander II, having received investiture at the hand of the emperor Henry, by the ring and pastoral staff; he was afterwards seized with remorse, resigned his see, and retired to Cluny. In 1073 Gregory VII recalled him, and reinstated him in the bishopric. This pope employed him in various legations, and, among others, in 1084, charged him with the office of reconciling to the Church, as his legate in all Italy, those who deserted the emperor's cause. He died in 1086, having written two books against Guibert the antipope and his followers; and a work, composed of sentences from various authors, to show that the powers of the Church are not under the control of the king or Caesar.
