Probably the oldest purpose of art is as a vehicle for religious ritual. From the prehistoric cave paintings of France, to the Sistine Chapel, art has served religion. For centuries the Church was the primary patron of artists. In traditional societies even today, the primary purpose of art is religious or ceremonial.
Art may also serve as a commemoration of an important event. The event may be of major historical importance, such as the coronation of Josephine by Napoleon as recorded by the artist David, or it may be important only to the participants, like the image of a wedding or a baptism.
Art has often served as propaganda or social commentary. Propaganda images are attempts to persuade us toward particular viewpoints or actions promoted by public or private institutions such as political parties, lobbyists, governments, or religious groups. The propaganda purpose may be one we approve of, such as World War II efforts to get women behind the war effort, as epitomized in Norman Rockwell's Rosie the Riveter. It might also be a purpose we disapprove of. In either case, the power of visual images has frequently been used to persuade masses of people to accept beliefs, take action, or follow leaders. The artist as social commentator may simply make us more aware of the human condition as he/she perceives it, without suggesting particular action. All societies engage in propaganda, but here are some links to propaganda art created in China, and by the Allies during World War I. and during World War II.
Art may be simply a means of recording of visual data-- telling the "truth" about what we see. After the Renaissance, artists became preoccupied with new ways of capturing reality such as the use of linear perspective, and the realism possible through the use of oil painting technique. In time, artists like Courbet and Cezanne (and many who followed them) began in various ways to challenge the basic idea of what it is for an image to be true and real.
Art can also be seen as pleasing the eye- creating beauty. Yet the idea of beauty, like that of truth, has been challenged in the modern era. At one time, the artist was expected to portray perfection-- lofty and noble ideals of beauty. Yet as society became more industrialized and democratic, many thoughtful people began to broaden their notions of what could be beautiful. For example, Rembrandt could celebrate the tactile quality of paint and color in his picture of a side of beef, and Courbet and Millet could see beauty in the life of ordinary peasants.
Art is also a powerful means of storytelling. This was a common device of religious art of the Middle ages, for example in the frescoes by Giotto from the Church of San Francesco de Assisi , where sequences of panels were used to tell stories from the Scriptures or lives of saints. It is also the great gift of Norman Rockwell, who had the ability to tell powerful and subtle stories about ordinary people and events, in just one picture. A picture is truly worth a thousand words.
Art can also convey intense emotion.The expressive power of art can be seen in literal ways in the capturing of facial expression and body language. Certain religious art, and the works of expressionists such as Munch or Kirchner are charged with powerful emotions. Picasso, in works such as Guernica (also an example of powerful social commentary and storytelling) is able to communicate intense emotions. This is accomplished variously by use of dramatic or exaggerated color, light, form, and/or other elements.
