The Vatican on Monday said it has received a ransom demand to recover letters signed by Michelangelo, stolen from the Holy See nearly 20 years ago.
Two letters signed by Michelangelo, one written in its entirety by the Renaissance artist, were stolen from the Vatican's Fabbrica di San Pietro archive in 1997.

Let us pray at this Mass for the victims of this cruelty -- there are so many! And, we pray also for the perpetrators of such cruelty that the Lord will change their hearts."
