Circus - The Roman Racetrack Arena - Circus and the Circus Maximus
King Tarquin laid out an arena (arena comes from the Latin for sand: harena) known as the Circus Maximus. Down the center was a barrier (spina), with pillars at each end around which charioteers had to maneuver -- carefully. Julius Caesar enlarged this circus to 1800 feet in length by 350 feet wide
