In art, a commission is the hiring and payment for the creation of a piece, often on behalf of another. Artwork may be commissioned by private individuals, by the government, or businesses. Commissions often resemble endorsement or sponsorship.
In classical music, ensembles often commission pieces from composers, where the ensemble secures the composer's payment from private or public organizations or donors.
Throughout history, it has been common for rulers and governments to commission public art as a means of demonstrating power and wealth, or even for specific propaganda purposes.
In ancient Rome, large architectural projects were commissioned as symbols of imperial glory. The Roman Coliseum for example, was commissioned by Emperor Vespasian. Public statuary was widespread, depicting mythical and heroic figures. The frieze that is carved into the Marcus Column, located at the Campus Martius, depicts the figure of Victory, and would have been commissioned to honour successful military campaigns waged by Marcus Aurelius. Ancient Roman culture was anti-intellectual and held artists in low esteem, in contrast to ancient cultures such as the Greek or Babylonian. Despite this, however, the sheer amount of surviving artworks commissioned at the height of the Roman Empire are a testament to the rulers' recognition of art's effectiveness in influencing the public's opinions about its civilization and its government.
During the Renaissance, visual art flourished in the cities of Italy due to the patronage of wealthy merchants and government officials, such as Cesare Borgia. Leonardo da Vinci earned steady commissions for artwork ranging from paintings (such as the Virgin of the Rocks for the Church of San Francisco Grande), to murals (Last Supper for the monastery church of Santa Maria della Grazia), to sculptures (the Gran Cavallo at Sforza). The most famous commissioned artwork of the Renaissance may be the Sistine Chapel ceiling at the Vatican, painted by Michelangelo as a commission for Pope Julius II.
