A mantle (Greek: μανδύας, mandyas; Church Slavonic: мантия, mantiya) is an ecclesiastical garment in the form of a very full cape that extends to the floor, joined at the neck, that is worn over the outer garments.
In the Eastern Orthodox Church and the Eastern Catholic churches, the mantle is a monastic garment worn by bishops, hegumens, archimandrites, and other monastics in processions and while attending various church services, such as Vespers or Matins; but not when vested to celebrate the Divine Liturgy. Unlike the Western cope, the mantle is worn only by monastics. The klobuk is worn over the mantle.
The mantle was originally a cape worn simply to ward off the cold. The mantle was first mentioned in the Old Testament, as a garment worn by several prophets including Elijah and Elisha. In , the mantle passing from Elijah the prophet, to Elisha, his successor, symbolizes the passing of prophetic authority:
Depictions of monks on icons show the mantle in use from the earliest Christian times. The original monastic mantle was of simple material: black, brown or grey, depending on what was at hand. As time went on, the use of mantles of a particular color and style came to be established as specific monastic vesture. Over the years distinguishing colors and ornamentation came to be applied to the mantle to distinguish monastics of higher positions within the church, while still reminding them of the need for monastic humility.
In the contemporary practice of the Eastern Orthodox Church, Monks & Nuns wear solid black mantles. They also wear veils, differing between traditions and rank. In common practice, monks wear a black veil that covers a Kalimavkion, a cylindrical hat. Abbesses also wear this same veil and hat while nuns only wear the veil. The practice of wearing a kalimavkion below the veil has only arisen in the last 300 years, and prior to this period, monks either wore no veil, or wore a pointed veil, as seen in many Russians of the old rite and icons of African saints. Nuns have been wearing a veil, in addition to the mantle since at least the 11th Century.
