There is a lot of similarities between the Urfa Mosaic on the left and a catacomb fresco. More details to follow as additional information is gathered. But, I sense both images may have been sourced directly or indirectly from what eventually came to be known as the Shroud of Turin. Meaningful images continue to accumlate.
Hat tip to Diana Fulbright who provided the fresco image.
