Chariot racing was one of the most popular ancient Greek, Roman, and Byzantine sports. In Greece, chariot racing played an essential role in aristocratic funeral games from a very early time. With the institution of formal races and permanent racetracks, chariot racing was adopted by many Greek states and their religious festivals. Horses and chariots were very costly. Their ownership was a preserve of the wealthiest aristocrats, whose reputations and status benefitted from offering such extravagant, exciting displays. Their successes could be further broadcast and celebrated through commissioned odes and other poetry.
