Photo: "Rome catacomb reveals 'oldest' image of St Paul"

And just in time for the feast of Sts. Peter and Paul:

Vatican archaeologists using laser technology have discovered what they believe is the oldest image in existence of St Paul the Apostle, dating from the late 4th century, on the walls of catacomb beneath Rome.

Vatican newspaper Osservatore Romano, revealing the find on Sunday, published a picture of a frescoed image of the face of a man with a pointed black beard on a red background, inside a bright yellow halo. The high forehead is furrowed.

Experts of the Ponitifical Commission for Sacred Archaeology made the discovery on June 19 in the Catacomb of Santa Tecla in Rome and describe it as the "oldest icon in history dedicated to the cult of the Apostle," according to the Vatican newspaper. (Reuters)

And the UK Times gives us the actual image:

The Catacomb of Santa Tecla in Rome is actually near the Basilica Church of "Paul Outside the Walls."
