These depictions of Jesus provide a pretty good overview. However, when the article asserts that Jesus was not depicted with a beard until the fourth century, I would question that conclusion. The fresco at Dura Europos (second image) might have included a beard on Jesus’ chin. The state of the image makes it difficult to tell. Other early depictions borrowed from existing Greco-Roman depictions of gods or heroes (think stock art), who typically did not have beards. So the evidence is not quite so helpful for determining how to depict Jesus.
Isaiah 50:6 speaks prophetically about Jesus’ suffering and describes Him as bearded. That prophecy may have helped settle early Christian depictions that became standard in later centuries. It would be interesting to research the history of interpretation for Isaiah 50. That Jesus was of Jewish descent is beyond dispute.
