From The Sydney Morning Herald:
SANTA TECLA, Rome: The earliest known icons of four of Christ's apostles have been found in an elaborately decorated chamber in a catacomb beneath the streets of Rome.
Scientists used laser technology to remove a crust of dirt and calcium deposits and bring to light the brightly coloured 4th century paintings of the saints John, Paul, Andrew and Peter.
The images adorn the ceiling of a vault, carved out of volcanic rock, which provided the last resting place for a rich Roman noblewoman who converted to Christianity after it was declared legal by the emperor Constantine.
Oh my! What an exciting discovery. However, because of their fragility, not just anyone will be able to view the icons. Visitors will probably be limited to scholars. Still, for the rest of us, it's lovely to see photos.
