Greek art had a profound influence on Roman art, and one of the most significant influences was the use of perspective and chiaroscuro. Perspective is the technique of creating the illusion of depth in a two-dimensional artwork, while chiaroscuro is the use of light and shadow to create a sense of volume and realism. These techniques were not widely used in Roman art prior to the influence of Greek art, and their introduction had a major impact on the development of Roman art.
