Answer:
Our own assumptions of artifacts, based on what we already know
Claude Monet is very famous for his series of paintings where he would draw the same subject over and over again but in different lighting so they would all be slightly unique (Ex. His Lily Pads) His brushstrokes are very visible in his paintings and that’s what makes them so interesting. While they do focus on actual subjects, they are more blurred renditions and thus are not hyper realistic. Therefore your answer would be “some show objects at different times of the day or during different seasons.”
The center for the western roman empire was the city of Rome.
Light is the way you see a piece of art. You could see it in a negative or positive light similar to English "Connotations" It's important to see a picture from different light angles because you could see something in one that you didn't in another.
