Ancient Icons of Peter and Paul Discovered

From the Associated Press:

ROME – The earliest known icons of the Apostles Peter and Paul have been discovered in a catacomb under an eight-story modern office building in a working-class neighborhood of Rome, Vatican officials said Tuesday.

The images, which date from the second half of the 4th century, were discovered on the ceiling of a tomb that also includes the earliest known images of the apostles John and Andrew. They were uncovered using a new laser technique that allowed restorers to burn off centuries of thick white calcium carbonate deposits without damaging the dark colors of the original paintings underneath.
