An Improved Image And Feature
Artists were able to make a new version of the Savior. They used features from the older works, which explains why they are different but still similar. Back then, the artists wanted to create an ideal image of the Messiah. When they worked on their projects, they often based the appearance of Jesus Christ on earlier works of art of Him. This explains why this depiction has become so prevalent.
Original Work Of Art
Here is an example of what we have been talking about. Zeus from the Greek pantheon has always been shown as a long-haired god with a beard. Doesn’t that remind you of someone else? As a matter of fact, Zeus was often drawn in a white robe as well! Come to think of it, this is actually quite obvious when these similarities have been pointed out to you. The artists had to find the balance between adding original features and making the images look similar to the older ones.
