An altar was commissioned to depict the accomplishments of the roman emperor augustus (between 13 and 9 bce). what was the purpose of this artwork?

the above mentioned statements talks about the creativity of an artist and to what extend they can utilize and experiment on the objects provided.   differing size and subjects are given so that an image of wisdom is created. displaying a transition from light to dark in something by darkening sections in order to create a shadow. and lastly, putting bits and pieces together to formulate a new image.

can you rephrase the question? was there a picture to go along with it?
