Lasers uncover first icons of Sts. Peter and Paul

Jun 22, 2010 4:33:00 PM - thestate.com
Twenty-first century laser technology has opened a window into the early days of the Catholic Church, guiding researchers through the dank, musty catacombs beneath Rome to a startling find: the first known icons of the apostles Peter and Paul.

Vatican officials unveiled the paintings Tuesday, discovered along with the earliest known images of the apostles John and Andrew in an underground burial chamber beneath an office building on a busy street in a working-class Rome neighborhood.

The images, which date from the second half of the 4th century, were uncovered using a new laser technique that allows restorers to burn off centuries of thick white calcium carbonate deposits without damaging the brilliant dark colors of the paintings underneath.

The technique could revolutionize the way restoration work is carried out in the miles (kilometers) of catacombs that burrow under the Eternal City where early Christians buried their dead.

The icons were discovered on the ceiling of a tomb of an aristocratic Roman woman at the Santa Tecla catacomb, near where the remains of the apostle Paul are said to be buried.
