QUADRI'GA (τέθριππον ἅρμα). A team of four horses or other animals; thence a carriage drawn by four horses abreast, and more epecially applied to the racing chariots of the circus (see the following woodcut), or to those employed in public processions, triumphs, &c. (Cic. Liv. Suet. &c.) Carriages of this description were originally furnished with two poles and a long cross-bar or yoke, which stretched across the backs of all the four animals, in the same manner as shown by the first woodcut s. BIGA. But that practice was early set aside, and then the two centre horses only were yoked, the two outside ones being attached by traces, in the manner shown by the woodcut s. FUNALIS. Isidor. Orig. xviii. 35.
