The Medieval Technology Pages Stirrups Stirrups, the resting places for the feet while mounted on a horse, were unknown in both antiquity and Roman times. By the early Middle Ages they were well-known in China, Korea, India, and Japan. By the 7th or early 8th century they became known in Persia. Knowledge of stirrups then rapidly spread to other Arab lands and to Byzantium and quickly thereafter to France.
Stirrups provide a number of advantages to the horseback rider.
They provide an easy way to mount a horse as contrasted to the earlier methods, either using a wooden stool or leaping directly on to the horse's back. Further, they provide lateral stability while mounted, and, in a particular advantage to mounted warriors, make it much easier to strike to the left or right with a sword while mounted without losing one's seat. The introduction of stirrups into western Europe roughly coincided with the rise of the Frankish mounted cavalry. This, in turn, lead to the great stirrup controversy . Suffice it to say here that this proposal is now, after much examination of the evidence, considered to be wrong.
