Equestrian victors dedicated their chariots, or models of them, and their horses. These models might be large or small. We have notices of large chariot-groups at Olympia of Kleosthenes,[180] Gelo,[181] and Hiero of Syracuse;[182] of small ones of Euagoras,[183] Glaukon,[184] Kyniska,[185] and Polypeithes.[186] A large number of miniature models of chariots and horses in bronze and terra cotta have been found at Olympia,[187] some of which have no wheels. Many very thin foil wheels have also been found.[188] Furtwaengler[189] believes that these wheels are conventional reductions of whole chariots. Some of them are cast[190] and they are generally four-spoked, but two mule-car wheels are five-spoked.[191] These various models are so common and of so little value, however, that they may have had nothing to do with chariot-races.[192] Many great artists, _e. g._, Kalamis,[193] Euphranor,[194] and Lysippos,[195] are known to have made chariot-groups and it is reasonable to assume that some of these were votive in character. Besides dedications of chariot victors, we find at Olympia also those of horse-racers. These were similarly both large and small, with and without jockeys. Thus jockeys on horseback by Kalamis stood on either side of Hiero’s chariot.[196] Krokon of Eretria, who won the horse-race at the end of the sixth century B. C.,[197] dedicated a small bronze horse at Olympia.[198] The monument of the sons of Pheidolas of Corinth,[199] representing a horse on the top of a column, must have been small. Pausanias, in mentioning the two statues of the Spartan chariot victor Lykinos by Myron,[200] says that one of the horses which the victor brought to Olympia was not allowed to enter the foal-race, and therefore was entered in the horse-race. This story was probably told Pausanias by the Olympia guides and may have arisen from the smallness of one of the horses in the monument.[201] The sculptors Kalamis,[202] Kanachos,[203] and Hegias[204] are known to have made groups representing horse-victors, and Pliny derives the whole _genre_ of equestrian monuments from the Greeks.[205] Great numbers of small figures of horses and riders have been excavated at Olympia[206] and elsewhere.[207] Equestrian groups of various kinds were also known outside Olympia. Thus Arkesilas IV of Kyrene offered a chariot model at Delphi for a victory in 466 B. C;[208] the base found on the Akropolis of Athens and inscribed with the name Onatas probably upheld such a group;[209] the equestrian statue of Isokrates on the Akropolis was also probably a dedication for a victory in horse-racing.[210] DEDICATION OF STATUES AT OLYMPIA AND ELSEWHERE.
