The Good Shepherd - Catacombs of St. Callixtus, Rome

Today's image of The Good Shepherd is from the Catacombs of St. Callixtus in Rome. 

All the Christian catacombs in Rome include many of the earliest Christian works of art, well-preserved in the subterranean chambers, and they give us much information about early Christianity and the genesis of Christian art. 

Initially, since there was no “Christian art,” Christians utilized icons or styles commonly used in the Greco-Roman world.
