Mécène
Rulers, nobles and very wealthy people used patronage of the arts to endorse their political ambitions, social positions, and prestige. That is, patrons operated as sponsors. Many languages have terms for patrons (such as the English "mecenate") that are derived from the name of Gaius Maecenas, generous friend and adviser to the Roman Emperor Augustus. Some patrons, such as the Medici family of Florence, used artistic patronage to "cleanse" wealth that was perceived as ill-gotten through usury. Art patronage was especially important in the creation of religious art. The Roman Catholic Church and later Protestant groups sponsored art and architecture, as seen in churches, cathedrals, painting, sculpture and handicrafts.
