GUARDIAN: Apostle images from 4th century found under street in Italy

"Archaeologists exploring a Christian catacomb under a residential Roman street have unearthed the earliest known images of the apostles Andrew and John. Using a newly developed laser to burn away centuries of calcium deposits without damaging the paintings beneath, the team found the late 4th-century images in the richly decorated tomb of a Roman noblewoman."
