Due to the highly religious nature of ancient Ancient Egyptian civilization, many of the great works of ancient Egypt depict gods, goddesses, and Pharaohs, who were also considered divine. Ancient Egyptian art is characterized by the idea of order. Clear and simple lines combined with simple shapes and flat areas of color helped to create a sense of order and balance in the art of ancient Egypt. Ancient Egyptian artists used vertical and horizontal reference lines to maintain the correct proportions in their work. Political and religious, as well as artistic, order was also maintained in Egyptian art. To clearly define the social hierarchy of a situation, figures were drawn to sizes that were based not on their distance from the painter's perspective but on relative importance. For instance, the Pharaoh would be drawn as the largest figure in a painting no matter where he was situated, and a greater God would be drawn larger than a lesser god.
