(Equestris), a term chiefly used in the phrase equestrian statue, which signifies a statue representing a person mounted on horseback. The word is formed of the Latin eques, "knight, horseman," of equus, "horse."

EQUESTRIAN Games, among the Romans, horse-races, of which there were five kinds, the prodromus or plain horse-race, the chariot race, the decury-race about funeral piles, the ludi sevira, and the ludi neptunales.

EQUESTRIAN Order, among the Romans, signified their knights or equites; as also their troopers or horsemen in the field; the first of which orders stood in contradiction to the senators; as the last did to the foot, military, or infantry. Each of these distinctions was introduced into the state by Romulus.
