Here is a fascinating collection of images of Christ throughout history from 30 AD to present from religionfacts.com. Some basic facts and observations: Jesus was first represented by symbols like a lamb or fish. The earliest known image of Jesus is a fresco of the healing of the paralytic at Dura-Europos (c.230-40). Jesus first appears with a beard in the late 4th century (and then not consistently). The earliest depiction of the crucifixion is on a sarcophagus dated c.420 AD.
