Special performance equipment on chariots continued to advance. In Ancient Rome, a two horse chariot was called a biga, a three horse chariot was a triga, and a supercharged, four horse power chariot was called a quadriga. Hey, they all sound like great names for modern car models! Vroom, Vroom!
Unlike other Olympic events, charioteers in Greek races did not perform their sport in the nude. Like NASCAR drivers, they wore safety gear: The clothing was itself their safety gear... a sleeved garment called a xystis went down to the ankles and had a belt fastened at the waist. Two criss-crossed straps across the back prevented the xystis from filling up with air during the race. Roman charioteers wore more protective gear--perhaps because most were not slaves, but paid professionals. They word helmets, leg guards, body armor or chain mail and wrapped the reins around their forearms. In case of a crash they would be dragged along the ground and could be killed, so one final bit of protection was to carry a falx (a curved knife), used to cut their reins away in an emergency.
The race only began when each chariot was lined up next to each other--"keeping pace". Chariots in the outside lanes would be moving faster than the ones on the inner lanes. While flags are used in modern auto racing, mechanical devices shaped like eagles and dolphins were raised to start the race. Dolphins were lowered with each successive lap. In Rome, often the Emperor himself would start the race by dropping a white cloth called a mappa.
In the end, the winners were given their awards right away. An olive wreath was placed on their head. In the Roman Empire there would be cash awards or possibly a gift of a slave for the charioteer. Fame was also part of the game, as is the case today. Scorpus, a celebrated driver won over 2000 races before being killed in a collision at the ripe age of 27. Most charioteers had a short life expectancy. The most famous driver was Gaius Appuleius Diocles who won 1,462 out of 4,257 races. When Diocles retired at the age of 42 (after 24 years) his career winnings 35,863,120 sesterces--approximately 15 billion dollars today--making him the highest paid sports star in human history.
A couple of more interesting differences: Women weren't permitted at the races as they are today; and while today's largest NASCAR racetracks hold under 150,000 spectators, the Circus Maximus in Rome held 250,000!
Gentlemen, start your... er... feed your horses! Go!
