Horses have appeared in works of art throughout history, frequently as depictions of the horse in battle. The horse appears less frequently in modern art, partly because the horse is no longer significant either as a mode of transportation or as an implement of war. Most modern representations are of famous contemporary horses, artwork associated with horse racing, or artwork associated with the historic cowboy or Native American tradition of the American West. In the United Kingdom, depictions of fox hunting and nostalgic rural scenes involving horses continue to be made. Horses often appear in artworks singly, as a mount for an important person, or in teams, hitched to a variety of horse-drawn vehicles. History Prehistory The horse appeared in prehistoric cave paintings such as those in Lascaux, estimated to be about 17,000 years old. Prehistoric hill figures have been carved in the shape of the horse, specifically the Uffington White Horse, an example of the tradition of horse carvings upon hillsides, which having existed for thousands of years continues into the current age. The Upper Palaeolithic Vogelherd figurines discovered in Germany, miniature sculptures made of mammoth ivory attributed to paleo-humans of the Aurignacian culture that are among the world's oldest-known works of figurative art, include a figure of a horse.

The Greeks and Romans invented the equestrian statue; the best surviving example being the Equestrian statue of Marcus Aurelius in Rome. The Horses of Saint Mark are the sole surviving example from Classical Antiquity of a monumental statue of the Quadriga. The horse was less prevalent in early Christian and Byzantine art, overwhelmed by the dominance of religious themes. Renaissance and after The Renaissance period starting in the 14th century brought a resurgence of the horse in art. Painters of this period who portrayed the horse included Paolo Uccello, Benozzo Gozzoli, Leonardo da Vinci, Albrecht Dürer, Raphael, Andrea Mantegna, and Titian. In 1482 the Duke of Milan Ludovico il Moro, commissioned Leonardo da Vinci to create the largest equestrian statue in the world, a monument to the duke's father Francesco, however, Leonardo's horse was never completed, (until it was replicated in the
