This review covers key concepts for the final exam in art history. It defines art as a primarily visual medium that expresses ideas about human experience and the world. While no single definition applies universally, art is generally whatever a society or culture says it is. The definition fluctuates as cultures are alive and changing. Art engages attention in a way the everyday environment cannot. It assists in rituals, reflects customs, communicates thoughts and emotions, and educates about ourselves and the world. Art has content that is communicated through imagery, symbolic meaning, and the surroundings and customs of its culture.
