Claudius of Turin was the Catholic bishop of Turin from 817 until his death. He was a courtier of Louis the Pious and was a writer during the Carolingian Renaissance. He is most noted for teaching iconoclasm, a radical idea at that time in Latin Church, and for some teachings that prefigured those of the Protestant Reformation. He was attacked as a heretic in written works by Saint Dungal and Jonas of Orléans.
