But what did he really look like, as a man living in Judaea in the 1st century? This subject has long been of interest. It is worth emphasizing that images of Jesus over time give us clues on how Jesus was imagined in different environments, but say absolutely nothing about what he really looked like. Our images of Jesus were largely created in the Byzantine era (4th-6th centuries). Byzantine images of Jesus were based on the image of a Graeco-Roman deity, for example the famous statue of Olympian Zeus by Phidias in the 4th century BCE.
As time went on the sun god’s halo was also added to Jesus’s head to show his heavenly nature. The winged victory in the hands of Olympian Zeus was replaced with gesture of blessing, with the Bible held in Jesus’s hand instead of a spear. This iconography of Jesus with long hair, a beard and a halo comes from the 4th century onwards, with Jesus sitting on a heavenly throne, like Olympian Zeus, as cosmic judge of the world: the Alpha and Omega, beginning and end (Revelation 21:5-6, and 22:13).
But at the time of Jesus long tunics were usually worn by women, not men. The earliest extant images of Jesus in Roman catacomb paintings show him as a teacher/philosopher or magus (wonder-worker, with a wand), dressed in the common clothing of the time for a man: a knee length (essentially sleeveless) tunic (chitōn) and a long mantle (himation). He is also beardless and short-haired.
