Pope St. Gelasius I
There is some controversy about whether Gelasius was born in Rome or Africa, but he was elected pope in 492. In a dispute with Constantinople, he made strong arguments for the primacy of the See of Rome over the Eastern Churches, based on Christ's declaration to St. Peter. He also abolished the pagan Roman feast of Lupercalia. He died in 496. The Catholic Encyclopedia also takes not of his concern for the liturgy, saying that "in his zeal for the beauty and majesty of Divine service, Gelasius composed many hymns, prefaces, and collects, and arranged a standard Mass-book."
