Using the toy model and independent estimations as a guide, Sandor was able to establish the major dimensions of Roman racing chariots. It was made by someone who knew a lot about racing chariots," Sandor said. "The wheels originally rotated freely on the axle. The bronze chariot was probably a toy for a rich individual, perhaps even Emperor Nero, who, according to 1st-century historian Suetonius, used to play with toy chariots. Representing a biga, a two-wheeled racing chariot driven by two horses, the hand-sized bronze model is lacking one of the two galloping horses as well as the charioteer.

Unfortunately no actual Roman racing chariots have survived. "The solution makes full sense in engineering thinking, ancient or modern," Sandor told Seeker. "Any iron tire for racing would be a very thin strip of iron on the outside of the wooden rim, best when heat-shrunk on the wood, to consolidate the whole wheel.Īdding the strip of iron to the right wheel improved a charioteer's chances of winning a race to roughly 80 percent, according to a study published in the latest issue of the Journal of Roman Archaeology. "The basic wheels were always of wood, animal hide glue, and rawhide strips (at critical joints) that tighten upon drying, like clamps," explained author Bela Sandor, professor emeritus of engineering physics at the University of Wisconsin at Madison. To increase the winning chances in the Formula One of the ancient Romans, an iron rim was mounted on the right wheel only of the two-wheeled chariot. That chariot wasn't just hopelessly huge and heavy - it did not have proper tires.Ī study of a 2,000-year-old toy chariot found in the Tiber River in the early 1890's and now on display at the British Museum, has revealed a secret trick. When most people imagine chariot racing in ancient Rome, they likely picture the thrilling race portrayed in the epic blockbuster "Ben-Hur." Yet it's unlikely the heavy chariot driven by Charlton Heston would ever win a real race.
