Saint Agobard, a Frankish theologian, born in 770, died June 6, 840. He became archbishop of Lyons in 816, and was deposed by the council of Thionville in 835 for the part he had taken in the revolt of Lothaire against Louis le Debormaire (833), but was promptly restored, having become reconciled with the emperor. He wrote several controversial theological works against image worship, the belief in witchcraft, and duelling; his principal opponent in discussing these questions was Felix of Urgel. Editions of Agobard's works were published in 1605 and in 1666 in Paris, and a book of his against the Jews was translated into German in 1852.
