A cataphract (from the Greek κατάφρακτος katafraktos, plural katafraktoi) was a form of heavy cavalry used by nomadic eastern Iranian tribes and dynasties and later Greeks and Latin-speaking peoples. Historically the cataphract was a heavily armed and armoured cavalryman who saw action from the earliest days of Antiquity up through the High Middle Ages. Originally, the term cataphract referred to a type of armour worn to cover the whole body and that of the horse.
