Purportedly issued by the fourth century Roman Emperor Constantine I, the Donation grants Pope Sylvester I and his successors, as inheritors of St. Peter, dominion over lands in Judea, Greece, Asia, Thrace, Africa, as well as the city of Rome, with Italy and the entire Western Roman Empire, while Constantine would retain imperial authority in the Eastern Roman Empire from his new imperial capital of Constantinople. The text claims that the Donation was Constantine's gift to Sylvester for instructing him in the Christian faith, baptizing him and miraculously curing him of leprosy.
