“ HARNESS (from O. Fr. harneis or harnois; the ultimate origin is obscure; the Celtic origin which connects it with the Welsh haiarn, iron, has phonetic and other difficulties; the French is the origin of the Span. arnes, and Ger. Harnisch) , probably, in origin, gear, tackle, equipment in general, but early applied particularly to the body armour of a soldier, including the trappings of the horse; now the general term for the gear of an animal used for draft purposes, traces, collar, bridle, girth, breeching, &c. It is usually not applied to the saddle or bridle of a riding animal. ”
