The artistic representation may be exaggerated?
Yes they do. Based on how old the artwork is, who created it, and the condition that it is in, determines to value of the aforementioned artwork. <span />
The answer would be Catholic Arts are mostly base their arts in the bible and about their religion while the Protestant art rejected mostly of the arts from catholic arts and create a simpler and new way of arts. They depict it because they want to be different from the catholic and its also because of the reformation.
