The cape (Arabic, burnus) is a liturgical outer vestment in the form of a loose sleeveless cloak made of linen or silk and embroidered with crosses or other religious inscriptions. It is worn by priests and bishops, the latter having a shield-shaped section attached at the back, studded with precious stones.
