Tonsure

Religious shaving of hair on the head

Tonsure is the practice of cutting or shaving some or all of the hair on the scalp as a sign of religious devotion or humility. The term originates from the Latin word tonsura (meaning "clipping" or "shearing") and referred to a specific practice in medieval Catholicism, abandoned by papal order in 1972. Tonsure, in its earliest Greek and Roman origin, was used as a sign or signifier for slavery.
