Artists who work realistically depict the world around them as accurately as possible. German artist Albrecht Dürer made highly detailed studies of animals, adding dense, delicate lines to create the fluffy, lifelike texture of a rabbit’s fur and long wispy lines to illustrate its whiskers. In Bonaparte Crossing the Great Saint Bernard Pass, Jacques-Louis David used crisp, vivid colors to paint Napoleon and his horse in the foreground. He painted the figures in the middle ground and the mountains in the background in muted, hazy colors to add atmospheric perspective. Rosa Bonheur observed animals up close and left few brushstrokes visible on the surface of paintings like Ploughing in the Nivernais, adding a sense of realism. Edgar Degas used wax to model a horse in motion in his Horse With Head Lowered. The work was cast in bronze after the artist’s death.
