An armill or armilla (from the Latin: armillae remains the plural of armilla) is a type of medieval bracelet, or armlet, normally in metal and worn in pairs, one for each arm. They were usually worn as part of royal regalia, for example at a coronation, or perhaps as part of especially grand liturgical vestments. They may have been worn outside ceremonies. Armillae presumably descend from the Ancient Roman armilla, which was a form of military decoration. These in turn seem to have developed from the armlets worn by some "barbarian" nations, including the ancient Celts and Scots. The form is variable; all three examples discussed below have completely different forms.
