cover or partial cover for the face or head used as a disguise or protection. Masks have been worn from time immemorial throughout the world. They are used by primitive peoples chiefly to impersonate supernatural beings or animals in religious and magical ceremonies. Particularly notable are the masks of W and central Africa; the wooden masks of the Native Americans of NW North America, which sometimes represented totemic animals; the False Face Society of the Iroquois, whose masked dancers were thought to ward off evil spirits; and the gold and turquoise-mosaic masks of Aztec warriors and priests. Masks have always been especially important in drama, and their use has been continued into modern times. They are an integral part of Japanese drama, especially of the No plays, and of Chinese temple dramas (see Asian dramaAsian drama,

. The mask was used in the miracle dramas of the Middle Ages and appeared in the 20th cent. in the works of the German expressionist playwrights and in Eugene O'Neill's plays The Great God Brown and Lazarus Laughed. The making of death masks (reproduction of the face of a dead person) is an ancient practice. Roman death masks were made of wax, and Egyptian death masks of thin gold plate. The modern method first applies oil or grease to the face and next a coat of plaster of paris, which is permitted to harden and is then removed. This procedure results in a mold that is used to cast the mask. Although a similar process was used for life masks, it often proved dangerous to the sitter and unsatisfactory in results. Protective masks include those used by medieval horsemen, gas masks, surgeon's masks, and masks used in certain athletic events. See African artAfrican art,

Masks may represent our persona and how we appear to others, the roles that we play in life such as parent, student, or worker. On the other hand, masks can be a symbol of pretentiousness. If you are wearing a mask, look inside and check if you are being sincere in your presentations, or if you are hiding something and pretending to be something you are not.
