The Rearing Steed, still in place on the Parthenon(5th century B.C.) A frieze representing the Panathenaic Procession originally encircled the cella (the most sacred part) of the Parthenon atop the Acropolis of Athens. The frieze was 500 feet long and 3 feet high. The greater part of that frieze is now in the British Museum in London. The sculpture was all supervised by the great Phidias and is generally revered as a climax in the ancient Greek art and a high point in the history of all art. In this procession of the Athenian people the troops of horsemen have always excited admiration. They picture a pride and joy in horsemanship and are a tribute to the breeding of fine horses. One of the most admired panels in the entire frieze is that of a single horseman who holds his spirited steed in check while he prepares to mount. The thoroughbred plunges and springs high with only one hoof touching the ground. The body of the horse has been made smaller than nature to bring the two figures into closer relationship but the entire scene is imbued with a dramatic action which anticipates the style of Greek art to come. The head of the horseman has been unfortunately destroyed in the original but is here reconstructed from a plaster cast from earlier times. He wears a Thracian fox-skin and a chiton, fastened only at the shoulder and slipping down from the implied action.
