Catacombs are underground tunnels used mainly as cemeteries. Italy has 120 in total, but the Catacomb of St. Thecla contains a particularly interesting discovery.
The oldest-known representations of Sts. Andrew, John and Paul have been found in this catacomb. These icons set the pattern the apostles were represented in following centuries.
These frescoes date back to the fourth century and continue to speak to Christians and non-Christians alike in the 21st century.
