GALLOP, in the manège, is the swiftest natural pace of a horse, performed by reaches or leaps; the two fore-feet being raised almost at the same time; and when these are in the air, and just ready to touch the ground again, the two hind-feet are lifted almost at once. The word is borrowed from the barbarous Latin calupare, or calpare, "to run." Some derive it from caballicare; others from the Greek καραδύειν, or καραδύειν, to spurr a horse.
