Hippodromus, Gr. and R. The Greek name for an arena for horse and chariot races, in contradistinction to the stadium, which served for foot-racing. Fig. [386] represents the hippodrome at Olympia, taken from Gell’s Itinerary of the Morea. The following is the key to the plan:—1, 2, and 3 are carceres; A, the space included between the stalls or carceres; B, starting-place for the chariots; C, the colonnade; D, the arena; E, the barrier; F, the goal; G, the space occupied by the spectators. [The word was also applied to the races themselves.] (See also Circus.)
