A mask is an article normally worn on the face, typically for protection, concealment, performance, or amusement. Masks have been used since antiquity for both ceremonial and practical purposes. They are usually worn on the face, although they may also be positioned for effect elsewhere on the wearer's body, so in parts of Australia giant totem masks cover the body, whilst Inuit women use finger masks during storytelling and dancing.[1]

The word "mask" came via French masque and either Italian maschera or Spanish máscara. Possible ancestors are Latin (not classical) mascus, masca = "ghost"; Hebrew masecha= "mask"; Arabic maskharah مَسْخَرَۃٌ = "jester", "man in masquerade", maskhara مَسْخَرَ = "he ridiculed, he mocked", masakha مَسَخَ = "he transfomed" (transitive).

Throughout the world masks are used for their expressive power as a feature of masked performance - both ritually and in various theatre traditions. The ritual and theatrical definitions of mask usage frequently overlap and merge but still provide a useful basis for categorisation. The image of juxtaposed Comedy and Tragedy masks are widely used to represent the Performing Arts, and specifically Drama.
