The mitre or miter (from the Greek μιτρα, 'headband' or 'turban') is a type of headgear now known as the traditional, ceremonial head-dress of bishops and certain abbots in the Roman Catholic Church, the Anglican Communion, and also bishops and certain other clergy in the Eastern Orthodoxy and Oriental Orthodoxy.

Secular

The camelaucum or καμιλαυκα, the ancestral headdress to the both the Western mitre and the Papal tiara, was originally a cap used by officials of the Imperial Byzantine court. In the late Empire it developed into the closed type of Imperial crown.

Christian clergy

Western Christianity

In its modern form in Western Christianity, the mitre is a tall folding cap, consisting of two similar parts (the front and back) rising to a peak and sewn together at the sides. Two short lappets always hang down from the back.

Three types of mitres are worn by Roman Catholic clergy for different occasions:

• The simplex is made of undecorated white linen or silk and is worn most notably at funerals and Good Friday. It is also worn when concelebrating Mass with the pope.
• The pretiosa is decorated with precious stones and gold and worn on Sundays and feast days.
• The auriphrygiata is of plain gold cloth or white silk with gold or silver embroidered bands and isused for penitential seasons. The miter made up entirely of the cloth of gold is usually reserved for ordinations, including episcopal consacration, and for the blessing of an abbot. In rites of ordination, no other miter should be used by the celebrant but the plain golden mitre.

With his inauguration as pope, Benedict XVI has broken with tradition and has replaced the tiara even on his papal coat of arms with a mitre and pallium. Prior to Pope Benedict XVI, each coat of arms always contained the image of the papal tiara and keys, even though the tiara had fallen into disuse in recent years, especially under Popes John Paul I and John Paul II. Pope Paul VI had allowed for his papal reign to have begun with a formal coronation in June of 1963. However, as a sign of the need for greater simplification of the papal rites, as well as a sign of the changing nature of

The mitre has always been used to surmount the coats of arms of bishops in the Church of England (instead of a crest, which is not used by clergy). The mitre fell out of use in the Church of England after the middle ages, but was resumed in the late 19th and early 20th centuries, and is now worn by most Anglican bishops on at least some occasions.

Eastern Christianity

The most typical mitre in Eastern Christianity is based on the closed Imperial crown of the late Byzantine Empire. Therefore, it too is ultimately based on the older καμιλαυκα although it diverged from the secular headdress at a much later date and after it had already undergone further development. It is made in the shape of a bulbous crown, often richly decorated with jewels and brocade and, in the case of the episcopal mitre, topped by a cross. As an item of Imperial regalia, along with other such items such as the sakkos or Imperial dalmatic, it signified the temporal authority of bishops (especially the Patriarch of Constantinople) within the administration of the Rum millet, or Christian community, of the Ottoman Empire.

In the Eastern Orthodox and counterpart Eastern Catholic churches it is a prerogative of the bishop, but may be awarded to archpriests, protopresbyters and archimandrites. The priestly mitre is not surmounted by a cross, and is awarded at the discretion of a synod.

Oriental Orthodox bishops sometimes use mitres, either of the Western or Eastern style. In the past, Coptic bishops have worn the ballin, an omophorion wound around the head like a turban. Syriac Orthodox bishops wear the maşnaphto (literally, 'turban') when presiding at the Divine Liturgy. This is a large, richly embroidered hood, often depicting the Holy Spirit as a dove. Armenian Orthodox bishops wear Western style mitres.
