Pope Gelasius I was Pope from 1 March 492 to his death in 496. He was probably the third and last Bishop of Rome of Berber descent in the Catholic Church. Gelasius was a prolific writer whose style placed him on the cusp between Late Antiquity and the Early Middle Ages. Gelasius had been closely employed by his predecessor Felix III, especially in drafting papal documents. His ministry was characterized by a call for strict orthodoxy, a more assertive push for papal authority, and increasing tension between the churches in the West and the East.
