The trigarium was an equestrian training ground in the northwest corner of the Campus Martius in ancient Rome. Its name was taken from the triga, a three-horse chariot.

A quadriga is a car or chariot drawn by four horses abreast and favoured for chariot racing in classical antiquity and the Roman Empire. The word derives from the Latin quadrigae, a contraction of quadriiugae, from quadri-: four, and iugum: yoke. In Latin the word quadrigae is almost always used in the plural and usually refers to the team of four horses rather than the chariot they pull. In Greek, a four-horse chariot was known as τέθριππον téthrippon.
