How did art and architecture reflect a transformation from pagan to Christian culture during the time of the Byzantine Empire?

Answer:
During the transformation from paganism to Christianity, the subject of art changed greatly in the Byzantine Empire. Christian works were more likely to display Jesus, Mary, saints, or other religious figures. Also, as far as architecture goes, the outsides of building became plainer, and the insides more elaborate, to demonstrate how earthly happiness and goodness should be sacrificed for heavenly happiness and goodness.
