religon has always played a key role in art expression. how do think that has changed in primitive days

Well, for one, religion has changed, as well as the practice of those religions. Christianity and Islam, the world's largest religions, did not exist/rise to prevalence until just prior to the Middle Ages. The changing nature and expression of religion would certainly cause differences in art expression. Certain religions were also oppressed through the eras you've mentioned, and oppression and fear are powerful emotions that would also influence art. There are a million different factors that go into this, but I hoped this helped a little.

Explanation:

Religion has played a key role in the change of art expression from primitive times through the Renaissance to day. I think it has changed because of culture, economy, and society.
