Rerebrace

A rerebrace (sometimes known as an upper cannon^[1]) is a piece of armour designed to protect the upper arms (above the elbow). Splint rerebraces were a feature of Byzantine armour in the Early Medieval period. The rerebrace seems to have re-emerged in England, in the early 14th century.^[2] As part of the full plate armour of the Late Middle Ages and Renaissance the rerebrace was a tubular piece of armour between the shoulder defences (spaulder or pauldron) and the elbow protection (couter).
