A material difference may be observed in the games of antiquity: the most eminent of the Greeks were actors, the Romans were merely spectators. The Olympic stadium was open to wealth, merit, and ambition; and if the candidates could depend on their personal skill and activity, they might pursue the footsteps of Diomede and Menelaus, and conduct their own horses in the rapid career... But a senator, or even a citizen, conscious of his dignity, would have blushed to expose his person or his horses in the circus of Rome. The games were established at the expense of the republic, the magistrates, or the emperors; but the reins were abandoned to servile hands; and if the profits of a favourite charioteer sometimes exceeded those of an advocate, they must be considered as the effects of popular extravagance, and the high wages of a disgraceful profession.
