From beneath the streets of Rome:

The oldest known image of the apostles Andrew and John have been discovered in catacombs under the city of Rome, dating back to the 4th century AD, archaeologists announced Tuesday.

The paintings were found in the same location where the oldest known painting of St. Paul was discovered last year, the Pontifical Commission for Sacred Archeology said Tuesday.

They are part of a group of paintings around an image of Jesus as the Good Shepherd on the ceiling of what is thought to have been a Roman noblewoman's tomb, experts said.

A painting of St. Peter makes up the fourth member of the group, but older images of him are thought to exist, Vatican experts said.
