In A.D. 79, an eruption of the volcano Vesuvius destroyed the city of Pompeii, covering it with layers of lava that hardened into rock. The wall paintings preserved in this rock tell us nearly everything we know about Roman painting.
Painting was usually done as a form of decoration. In Pompeii, for example, paintings were executed on the inside walls of the houses in fresco (painting on wet plaster). Often these murals were used to make the room seem larger, by giving the illusion of depth, or to create a pastoral landscape where there was no window or view.
Columns and other forms of architecture were often painted into the compositions or used to frame the murals and add to the feeling of depth. A system of perspective was known and used by the Romans. Red, black, and cream-white were among the most popular colors.
Roman painting achieved a high degree of naturalism through the artists' understanding of perspective and use of light and shade. The Romans painted many charming scenes from nature and portraits of children and beautiful young men and women. Religion, too, inspired their art.
