Stirrup

A stirrup is a light frame or ring that holds the foot of a rider, attached to the saddle by a strap, often called a stirrup leather. Stirrups are usually paired and are used to aid in mounting and as a support while using a riding animal (usually a horse or other equine, such as a mule). They greatly increase the rider's ability to stay in the saddle and control the mount, increasing the animal's usefulness to humans in areas such as communication, transportation, and warfare. In antiquity, the earliest foot supports consisted of riders placing their feet under a girth or using a simple toe loop appearing in India by the 2nd century BC. Later, a single stirrup was used as a mounting aid, and paired stirrups appeared after the invention of the treed saddle. The stirrup was invented in China in the first few centuries AD and spread westward through the nomadic peoples of Central Eurasia. The use of paired stirrups first appeared in the Chinese Jin dynasty during the 4th century, was in common use throughout China by the 5th century, and spread across Eurasia to Europe by the 7th or 8th century. Some argue that the stirrup was one of the basic tools used to create and spread modern civilization, possibly as important as the wheel or printing press. The English word "stirrup" stems from Old English stirap, stigrap, Middle English stirop, styrope, i.e. a mounting or climbing-rope. Compare Old English stīgan "to ascend" and rap "rope, cord". The stirrup, which gives greater stability to a rider, has been described as one of the most significant inventions in the history of warfare, prior to gunpowder. As a tool allowing expanded use of horses in warfare, the stirrup is often called the third revolutionary step in equipment, after the chariot and the saddle. The basic tactics of mounted warfare were significantly altered by the stirrup. A rider supported by stirrups was less likely to fall off while fighting, and could deliver a blow with a weapon that more fully employed the weight and momentum of horse and rider.
