A mask is an object normally worn on the face, typically for protection, disguise, performance, or entertainment and often they have been employed for rituals and rights. Masks have been used since antiquity for both ceremonial and practical purposes, as well as in the performing arts and for entertainment. They are usually worn on the face, although they may also be positioned for effect elsewhere on the wearer's body. More generally in art history, especially sculpture, "mask" is the term for a face without a body that is not modelled in the round (which would make it a "head"), but for example appears in low relief. Etymology The word "mask" appeared in English in the 1530s, from Middle French masque "covering to hide or guard the face", derived in turn from Italian maschera, from Medieval Latin masca "mask, specter, nightmare". This word is of uncertain origin, perhaps from Arabic maskharah مَسْخَرَۃٌ "buffoon", from the verb sakhira "to ridicule". However, it may also come from Provençal mascarar "to black (the face)" (or the related Catalan mascarar, Old French mascurer). This in turn is of uncertain origin – perhaps from a Germanic source akin to English "mesh", but perhaps from mask- "black", a borrowing from a pre-Indo-European language. One German author claims the word "mask" is originally derived from the Spanish más que la cara (literally, "more than the face" or "added face"), which evolved to "máscara", while the Arabic "maskharat" – referring to the buffoonery which is possible only by disguising the face – would be based on these Spanish roots. Other related forms are Hebrew masecha= "mask"; Arabic maskhara مَسْخَرَ = "he ridiculed, he mocked", masakha مَسَخَ = "he transfomed" (transitive). History The use of masks in rituals or ceremonies is a very ancient human practice across the world, although masks can also be worn for protection, in hunting, in sports, in feasts, or in wars – or simply used as ornamentation. Some ceremonial or decorative masks were not designed to be worn. Although the religious use of masks has waned, masks are used sometimes in drama therapy or psychotherapy. One of the challenges in anthropology is finding the precise derivation of human culture and early activities, the invention and use of the mask is only one area of unsolved inquiry. The use of masks dates back several millennia. It is conjectured that the first masks may have been used
