Tonsure

Wikipedia's first sentence called it “practice of some christian churches of cutting the hair from the scalp of clerics as a symbol of their renuncia”. Today it says “practice of cutting or shaving some or all of the hair on the scalp as a sign of religious devotion or humility”. The one-line description Wikipedia serves to search engines and AI systems read “Hairstyle related to religious devotion Roman”. It now reads “Religious shaving of hair on the head Roman”.

The opening as it read in 2005

Tonsure is the practice of some Christian churches of cutting the hair from the scalp of clerics as a symbol of their renunciation of worldly fashion and esteem.1 There were three forms of tonsure known in the seventh and eighth centuries: (1) The Oriental, which claimed the authority of St. Paul and consisted in shaving the whole head. This was observed by churches owing allegiance to Eastern Orthodoxy . Hence Theodore of Tarsus , who had acquired his learning in Byzantine Asia Minor and bore this tonsure, had to allow his hair to grow for four months before he could be tonsured after the Roman fashion, and then ordained Archbishop of Canterbury by Pope Vitalian in 668 . (2) The Celtic, which consisted of shaving the whole front of the head from ear to ear, the hair being allowed to hang down behind. An alternate explanation (apparently first set forward in the article On The Shape Of The Insular Tonsure ) 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 practicers 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 which had become obsolete elsewhere. Roman tonsure (3) The Roman: this consisted in 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 Catholic church until obligatory tonsure was abolished in 1972 . Needless to say, these claimed origins are unhistorical; the early history of the tonsure is lost in obscurity. This practice is not improbably connected with the Roman idea that long hair is the mark of a freeman , while the shaven head marks the slave . Based on Charles Plummer's essay, "Excursus on the Paschal Controversy and Tonsure" (in his edition of Bede's Opera Historica , 1898).2
