Settling on a ‘Look’
Over time, people began expecting depictions of Jesus to look the same. As well as his facial features, he began to appear in a white robe. Occasionally he would have a halo floating above his head. Jean says this was because the populace wanted to be able to see Jesus as evangelical.
Catching the Eye
The result of painting him like this was to show Jesus as hallowed or divine. If you think of modern-day superheroes and old Roman and Greek gods, long hair is depicted regularly as a sign of strength, and today this holds the same connotations. The overall image of Jesus has become an analogy of those characters.
