Patr. of Constantinople. He withdrew from court life and retired to a monastery, but was recalled to Constantinople and in 806 made Patriarch, though not yet in Holy Orders. In return, the Emp. Nicephorus I demanded his reinstatement of a priest who had been deposed for blessing the adulterous marriage of the Emp. Constantine VI; after some hesitation the Patriarch gave way. When the Emp. Leo V (813–20) resumed an iconoclastic policy, Nicephorus resisted; he was exiled in 815 and retired to his former monastery. Besides writing in the image controversy, he compiled a Byzantine history from 602 to 770. Feast day in the E. Church, 2 June; in the W., 13 Mar.
