Which are examples of the roles of the popes and patrons of the arts in restoring the city of rome?

Both patrons and different popes had a positive influence in the rebuilding of the city of Rome and returning it to its former glory. They did this by comissioning artists, painters, and sculpturers to work on different works of art that were then used in churches and other public places. This improved the outlook and the general feel of this city through time.
