Nativity with Saint Francis and Saint Lawrence

Still missing since 1969. Caravaggio's altarpiece was taken from its oratory in Palermo by two thieves on the night of October 17 to 18, 1969, and it has not been seen publicly since. In 2005 the FBI put it on its list of the Top Ten Art Crimes. Investigators think it may still be hidden somewhere in Sicily, though that remains a working theory rather than a finding. Since December 12, 2015 a replica has hung on the altar, which at least lets visitors see the composition where it was meant to be seen.
