“Bread and circuses,” the poet Juvenal wrote scathingly. “That’s all the common people want.” Food and entertainment. Or to put it another way, basic sustenance and bloodshed, because the most popular entertainments offered by the circuses of Rome were the gladiators and chariot racing, the latter often as deadly as the former. As many as 12 four-horse teams raced one another seven times around the confines of the greatest arenas—the Circus Maximus in Rome was 2,000 feet long, but its track was not more than 150 feet wide—and rules were few, collisions all but inevitable, and hideous injuries to the charioteers extremely commonplace. Ancient inscriptions frequently record the deaths of famous racers in their early 20s, crushed against the stone spina that ran down the center of the race track or dragged behind their horses after their chariots were smashed.
Charioteers, who generally started out as slaves, took these risks because there were fortunes to be won. Successful racers who survived could grow enormously wealthy—another Roman poet, Martial, grumbled in the first century A.D. that it was possible to make as much as 15 bags of gold for winning a single race. Diocles, the most successful charioteer of them all, earned an estimated 36 million sesterces in the course of his glittering career, a sum sufficient to feed the whole city of Rome for a year. Spectators, too, wagered and won substantial sums, enough for the races to be plagued by all manner of dirty tricks; there is evidence that the fans sometimes hurled nail-studded curse tablets onto the track in an attempt to disable their rivals.
In the days of the Roman republic, the races featured four color-themed teams, the Reds, the Whites, the Greens and the Blues, each of which attracted fanatical support. By the sixth century A.D., after the western half of the empire fell, only two of these survived—the Greens had incorporated the Reds, and the Whites had been absorbed into the Blues. But the two remaining teams were wildly popular in the Eastern, or Byzantine, Empire, which had its capital at Constantinople, and their supporters were as passionate as ever—so much so that they were frequently responsible for bloody riots.
