Nativity with St. Francis and St. Lawrence considered a 17th century masterpiece, created by Italian painter Caravaggio in 1609. Nativity has been missing since it was nicked by thieves in Palermo in 1969. No one for sure knows who stole it, or why they stole it, but what might have become of it has sparked dozens of tales. One prominent theory is that it was stolen by the mafia – and, quite possibly, eaten by pigs.See omnystudio.com/listener for privacy information.
