Hich is not a purpose of church mosaics?

The correct answer (since there are not any choices listed) should be something about dealing with nature. The churches did not agree with the thought of nature being what was important biblicaly or religiously. Nature  would symbolize science rather than religion.  Many placed mosaics in churches by the means of windows. This helped give the mosaics a radiance, such as that of God and his angels would display. 

Because it is an outlet. most people are very shut off so they will write poetry to.. almost rant. sometimes people can’t say their feelings out loud so they make it into an art form that is poetry, and write it down.
