What are the changes you notice between Roman and Early Christian art and architecture, and what can account for them? (for example: differences in temple architecture vs. Christian church buildings).

Roman art was primarily interested in portraits of wealthy patrons, war memorials and portrayals of gods and goddesses. They also liked to copy Greek artworks. During the 4th century A.D, however, a new group rose to power through the conversion of the Emperor Constantine to the Christian faith. Christianity was eventually declared the official religion of the Roman Empire. Naturally, this changed the focus of the artworks from gods and goddesses of Greece and Rome to Christian saints. Also, artworks commissioned by wealthy patrons were now intended to grace the churches of the Christian faith. Large communal places of worship were constructed, similar to the former Greek and Roman styled temples, but whereas temples were generally constructed as open to the air, churches were enclosed, more private and sheltered. This makes sense, as often Greek and Roman gods and goddesses were "in charge" of the elements and of nature, so their temples were open. The very enclosed construction of Christian places of worship emphasized the difference between this "new" religion and the pagan ones that went before.
