The correct answer is Pope Leo X. His actual name is <span>Giovanni di Lorenzo de' Medici, and he lived during parts of the 15th and 16th centuries. He is most famous for his indulgences, which he sold to people in order to absolve them of their sins in return for their money which he used to build St. Peter's Basilica in Rome.</span>
Martin Luther sends his complaints to Archbishop Albert of Mainz, who had approved the granting of indulgences for contributions to help pay for the building of the new St. Peter's Church in Rome, and another copy to Bishop Hieronymus Scultetus of Brandenburg, who was the Ordinary of the University of Wittenberg where <span>Luther taught.</span>
