I noticed a lot of places of worship depicted in the art which is hard to recognize as a false Idol. If I had been an artist in this era I would be worried about painting anything but Jesus, God the Father, or the virgin Mary. This is a very difficult question to answer easily because many people have different beliefs and feelings on religion.
During this period of time we see a shift in art and what is acceptable, this is directly related to the church and preaching of the time, I look at it as a more strict church possibly even borderline fanatical. This is not the first or the last time that art will be influenced by the church or state. My personal feeling is that this more strict approach to art stems from the church having nothing else to worry about at the time. A good war would have curtailed the churches power over the people and the state allowing artists more freedom of content.
