I’ve taught a series on depictions of Jesus numerous times at churches and for Sunday Schools of all flavors. This is one of the best pieces I’ve ever read on the subject. Thorough, but approachable.
Plus, there’s a connection to my beloved Dura Europos…
However, there is one other place to look: to the synagogue Dura Europos, dating from the early 3rd century. The depiction of Moses on the walls of the synagogue of Dura-Europos is probably the closest fit, I think, since it shows how a Jewish sage was imagined in the Graeco-Roman world. Moses is shown in undyed clothing, appropriate to tastes of ascetic masculinity (eschewing color), and his one mantle is a tallith, since one can see tassels (tzitzith). This image is a far more correct as a basis for imagining the historical Jesus than the adaptations of the Byzantine Jesus that have become standard.
