Archbishop of Lyons from 816 to 840, was one of the most enlightened and distinguished men of his age, the champion of truth, and the successful opposer of every form of superstition. Of his writings, which were rescued from destruction in a shop at Lyons in 1605, the principal are—a *Treatise against Felix D'Urge*; *Treatise against the Jews*; *Against Trial by Combat*; *On the Privileges and Rights of the Priesthood*; *Against Sorcery*; and the celebrated treatise *Against the Worship of Images*. 2 vols. 8vo, Paris, 1666.
