A quiver is a container for holding arrows or bolts. Generally of leather or wood and usually attached to a belt which is sometimes seen slung over the shoulder. Back quivers, however appear to be unknown from medieval Europe.
Examples of arrow quivers can be seen from Viking Age graves and from later Norman depictions but they seem to remove themselves by the high medieval period, at least in war, to be replaced by arrow bags. Crossbow quivers remain ubiquitous throughout the crossbows existence.
