Lanza Sagrada
In exchange for maintaining the custody of Cem, Bayezid paid Innocent VIII 120,000 crowns (at the time, equal to all other annual sources of papal revenue combined), a relic of the Holy Lance (which allegedly had pierced the side of Christ), one hundred Moorish slaves, and an annual fee of 45,000 ducats. Much of the costs associated with the Sistine Chapel were paid with funds from the Ottoman ransoms.
