Tonsure is the practice of some Christian churches, mystics, Buddhist novices and monks, and some Hindu temples of cutting the hair from the scalp of clerics, devotees, or holy people as a symbol of their renunciation of worldly fashion and esteem.
The Celtic, which consisted of shaving the whole front of the head from ear to ear, the hair being allowed to hang down behind. This is a style that was inherited from the old Druids. An alternate explanation describes the "delta" tonsure cut as a triangle with the apex at the forehead, and the base from ear to ear at the back of the head. The Roman party in Britain attributed the origin of the Celtic tonsure to Simon Magus, though some traced it back to the swineherd of Lóegaire mac Néill, the Irish king who opposed St. Patrick; this latter view is refuted by the fact that it was common to all of the Celts, both insular and continental. Some practitioners of Celtic Christianity claimed the authority of St. John for this, as for their Easter practices. It is entirely plausible that the Celts were merely observing an older practice, possibly from Antioch, which had become obsolete elsewhere.
The Roman: this consisted of shaving only the top of the head, so as to allow the hair to grow in the form of a crown. This is claimed to have originated with St. Peter, and was the practice of the Latin RiteRoman Catholic Church until obligatory tonsure was suppressed in 1972.
These claimed origins are possibly unhistorical; the earliest history of the tonsure is lost in obscurity. This practice is not improbably connected with the idea that long hair is the mark of a freeman, while the shaven head marks the slave (in the religious sense: a servant of God).
Other theories are; that the tonsure mimics male pattern baldness in an attempt to lend artificial respectability to men too young to display the real thing, or that the tonsure is a ritual created by balding superiors in act of vanity and power over young non-bald subordinates. Also in the documentaryA Hole in the Head, Amanda Feilding, an advocate of trepanation, related her theory that linked the tonsure to the practice of Trepanation.
Among the Germanic tribes there appeared the custom that an unsuccessful pretender or a dethroned king would be tonsured. Then, he had to retire to a monastery but sometimes this lasted only until his hair grew back.) The practice of tonsure, coupled with castration, was common for deposed Emperors and his sons in Byzantium from around the 8th century, prior to which execution, usually by blinding was the normal practice.
In the Latin or Western Rite of the Roman Catholic Church, "first tonsure" was, in medieval times, the rite of inducting someone into the clergy and qualifying him for the civil benefits then enjoyed by clerics. Tonsure was a prerequisite for receiving the minor and major orders. Failing to maintain tonsure was the equivalent of attempting to
abandon one's clerical state, and in the 1917 Code of Canon Law, any cleric in minor orders (or simply tonsured) who did not resume the tonsure within a month after being warned by his Ordinary, lost the clerical state. Over time, the appearance of tonsure varied, ending up for non-monastic clergy as generally consisting of a symbolic cutting of a few tufts of hair at first tonsure in the Sign of the Cross and in wearing a bare spot on the back of the head which varied according to the degree of orders. It was not supposed to be less than the size of a communicant's host, even for a tonsuratus, someone simply tonsured, and the approximate size for a priest's tonsure was the size
of a priest's host. Countries that were not Catholic had exceptions to this rule, especially in the English-speaking world. In England and America, for example, the bare spot was dispensed with, likely because of the persecutions that could arise from being a part of the Catholic clergy, but the ceremonious cutting of the hair in the first clerical tonsure was always required. In accordance with Pope Paul VI's motu proprioMinisteria quaedam of 15 August1972, "first tonsure is no longer conferred". Since that time, however, certain institutes have been authorized to use the first clerical tonsure, such as the Priestly Fraternity of St. Peter (1988), the Institute of Christ the King Sovereign Priest (1990), and the Personal Apostolic Administration of Saint John Mary Vianney, (2001).
Apart from this general clerical tonsure, some Western Rite monastic orders, for example Carthusians and Trappists, employed a very full version of tonsure, shaving the head entirely bald and keeping only a narrow ring of short hair, sometimes called "the monastic crown" (see "Roman tonsure", above), from the time of entrance into the monastic novitiate for all monks, whether destined for service as priests or brothers. Some monastic orders and individual monasteries still maintain the tradition of a monastic tonsure.
The fuller form of clerical tonsure led to the wearing of a skull cap in church to keep the head warm. This skull cap, called a zuchetto, is still worn by the Pope (in white), Cardinals (in red) and bishops (in purple) both during and outside of formal religious ceremonies. Priests may wear a simple black zuchetto, only outside of religious services, though this is almost never seen except as a practical garment used for warmth by some monks. Some priests who held special titles (certain ranks of monsignori and some canons, for instance) formerly wore black zuchettos with red or purple piping, but this too has fallen out of use except in a few, extremely rare cases.
Today in Eastern Orthodoxy and in the Eastern Catholic Churches of Byzantine Rite, there are three types of tonsure: baptismal, monastic, and clerical. It always consists of the cutting of four locks of hair in a cruciform pattern: at the front of head as the celebrant says "In the Name of the Father", at the back of head at the words "and the Son", and on either side of the head at the words "and the Holy Spirit". In all cases, the hair is allowed to grow back; the tonsure as such is not adopted as a hairstyle.
Baptismal tonsure is performed during the rite of Holy Baptism as a first sacrificial offering by the newly baptized. This tonsure is always performed, whether the one being baptized is an infant or an adult.
Monastic tonsure (of which there are three grades: Rassophore, Stavrophore and the Great Schema), is the rite of initiation into the monastic state, symbolic of cutting off of self-will. Orthodox monks traditionally never cut their hair or beards after receiving the monastic tonsure as a sign of the consecration of their lives to God (reminiscent of the Vow of the Nazirite).
Clerical tonsure is done prior to ordination to any rank, such as reader. This led to a once common usage that one was, for instance, "tonsured a reader", although technically the rite of tonsure occurred prior to the ordination.
In Buddhism tonsure is a part of the rite of pabbajja and also a part of becoming a monk. This involves shaving head and face. This tonsure is renewed as often as required to keep the head cleanly shaven, and some Chinese Buddhist monks will also have 6, 9 or 12 dots on the top of the head as well as 3 on both arms, the result of burning the shaven scalp and arms with the tip of an incense stick.
It is a ritual for pilgrims on the event of Hajj to shave their heads before entering Mecca. Shaving off hair from the head was considered an ancient symbol of becoming a slave in Arabia and when a pilgrim shaves his head, he declares himself to be the slave of his Lord.
