What is the name of the central barrier in the Circus Maximus?

The central barrier in the Circus Maximus is known as the Spina. This structure served as a dividing wall that ran down the center of the racetrack and was crucial in managing the races. The Spina was adorned with various statues, fountains, and obelisks, contributing to the overall spectacle of the events held at the Circus. Races typically involved chariots racing around the track, and the Spina was a focal point for the crowd, marking the point where the racers would turn and part of the challenge for the charioteers.

The other terms listed refer to different elements of Roman culture or sports. Metae are the turning posts at either end of the racing track, while Palaestra refers to an area for training in wrestling and other sports. Fritillus is not related to racing; it is a term used for a type of box used in the game of knuckle-bones. Understanding the role of these various terms helps place the meaning of Spina more clearly within the context of Roman sports and entertainment.
