If a viewBox attribute is specified for the element creating the SVG viewport, the reference box is positioned at the origin of the coordinate system established by the viewBox attribute and the dimension of the reference box is set to the width and height values of the viewBox attribute.
A mask is an object normally worn on the face, typically for protection, disguise, performance, or entertainment, and often employed for rituals and rites. 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.
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 by primitive people to associate the wearer with some kind of unimpeachable authority, such as a deity, or to otherwise lend credence to the person's claim on a given social role.
In the Greek bacchanalia and the Dionysus cult, which involved the use of masks, the ordinary controls on behaviour were temporarily suspended, and people cavorted in merry revelry outside their ordinary rank or status. Ren Gunon claims that in the Roman saturnalia festivals, the ordinary roles were often inverted. Sometimes a slave or a criminal was temporarily granted the insignia and status of royalty, only to be killed after the festival ended.[9] The Carnival of Venice, in which all are equal behind their masks, dates back to 1268 AD.[10] The use of carnivalesque masks in the Jewish Purim festivities probably originated in the late 15th century, although some Jewish authors claim it has always been part of Judaic tradition.[11]
The North American Iroquois tribes used masks for healing purposes (see False Face Society). In the Himalayas, masks functioned above all as mediators of supernatural forces.[12][13][14] Yup'ik masks could be small 3-inch (7.6 cm) finger masks, but also 10-kilogram (22 lb) masks hung from the ceiling or carried by several people.[15][16] Masks have been created with plastic surgery for mutilated soldiers.[17]
In many dramatic traditions including the theatre of ancient Greece, the classical noh drama of Japan (14th century to present), the traditional lhamo drama of Tibet, talchum in Korea, and the topeng dance of Indonesia, masks were or are typically worn by all the performers, with several different types of mask used for different types of character.
Ritual masks occur throughout the world, and although they tend to share many characteristics, highly distinctive forms have developed. The function of the masks may be magical or religious; they may appear in rites of passage or as a make-up for a form of theatre. Equally masks may disguise a penitent or preside over important ceremonies; they may help mediate with spirits, or offer a protective role to the members of a society who use their powers.[22] Biologist Jeremy Griffith has suggested that ritual masks, as representations of the human face, are extremely revealing of the two fundamental aspects of the human psychological condition: firstly, the repression of a cooperative, instinctive self or soul; and secondly, the extremely angry state of the unjustly condemned conscious thinking egocentric intellect.[23]
Many African masks represent animals. Some African tribes believe that the animal masks can help them communicate with the spirits who live in forests or open savannas. People of Burkina Faso known as the Bwa and Nuna call to the spirit to stop destruction. The Dogon of Mali have complex religions that also have animal masks. Their three main cults use seventy-eight different types of masks. Most of the ceremonies of the Dogon culture are secret, although the antelope dance is shown to non-Dogons. The antelope masks are rough rectangular boxes with several horns coming out of the top. The Dogons are expert agriculturists and the antelope symbolizes a hard-working farmer.[25]
Another culture that has a very rich agricultural tradition is the Bamana people of Mali. The antelope (called Chiwara) is believed to have taught man the secrets of agriculture. Although the Dogons and Bamana people both believe the antelope symbolises agriculture, they interpret elements the masks differently. To the Bamana people, swords represent the sprouting of grain.
Masks may also indicate a culture's ideal of feminine beauty. The masks of Punu of Gabon have highly arched eyebrows, almost almond-shaped eyes and a narrow chin. The raised strip running from both sides of the nose to the ears represent jewellery. Dark black hairstyle, tops the mask off. The whiteness of the face represents the whiteness and beauty of the spirit world. Only men wear the masks and perform the dances with high stilts despite the fact that the masks represent women. One of the most beautiful representations of female beauty is the Idia's Mask of Benin in present-day Edo State of Nigeria. It is believed to have been commissioned by a king of Benin in memory of his mother. To honor his dead mother, the king wore the mask on his hip during special ceremonies.[26]
The Senoufo people of the Ivory Coast represent tranquility by making masks with eyes half-shut and lines drawn near the mouth. The Temne of Sierra Leone use masks with small eyes and mouths to represent humility and humbleness. They represent wisdom by making bulging forehead. Other masks that have exaggerated long faces and broad foreheads symbolize the soberness of one's duty that comes with power. War masks are also popular. The Grebo of the Ivory Coast and Liberia carve masks with round eyes to represent alertness and anger, with the straight nose to represent unwillingness to retreat.[27]
Today, the qualities of African art are beginning to be more understood and appreciated. However, most African masks are now being produced for the tourist trade. Although they often show skilled craftsmanship, they nearly always lack the spiritual character of the traditional tribal masks.
The variety and beauty of the masks of Melanesia are almost as highly developed as in Africa. It is a culture where ancestor worship is dominant and religious ceremonies are devoted to ancestors. Inevitably, many of the mask types relate to use in these ceremonies and are linked with the activities of secret societies. The mask is regarded as an instrument of revelation, giving form to the sacred. This is often accomplished by linking the mask to an ancestral presence, and thus bringing the past into the present.
As a culture of scattered islands and peninsulars, Melanesian mask forms have developed in a highly diversified fashion, with a great deal of variety in their construction and aesthetic.[28] In Papua New Guinea, six-metre-high totem masks are placed to protect the living from spirits; whereas the duk-duk and tubuan masks of New Guinea are used to enforce social codes by intimidation. They are conical masks, made from cane and leaves.[29]
North American indigenous cultures in the Arctic and para-Arctic regions have tended towards simple religious practice but a highly evolved and rich mythology, especially concerning hunting. In some areas, annual shamanic ceremonies involved masked dances and these strongly abstracted masks are arguably the most striking artifacts produced in this region. Inuit groups vary widely and share neither a common mythology nor language. Not surprisingly their mask traditions are also often different, although their masks are often made out of driftwood, animal skins, bones, and feathers. In some areas Inuit women use finger masks during storytelling and dancing.[30]
Indigenous Pacific Northwest coastal cultural groups generally included highly skilled woodworkers. Their masks were often masterpieces of carving, sometimes with movable jaws, with the parts sometimes moved by pulling cords, or a mask within a mask to represent a magical transformation. The carving of masks was an important feature of woodcraft, along with many other features that often combined the utilitarian with the symbolic, such as shields, canoes, poles, and houses.
Woodland tribes, especially in the northeastern and around the Great Lakes, cross-fertilized culturally with one another. The Iroquois made spectacular wooden 'false face' masks, used in healing ceremonies and carved from living trees. These masks appear in a great variety of shapes, depending on their precise function.
Pueblo craftsmen produced impressive work for masked religious ritual, especially the Hopi and Zuni. The kachinas (gods and spirits) frequently take the form of highly distinctive and elaborate masks that are used in ritual dances. These are usually made of leather with appendages of fur, feathers, or leaves. Some cover the face, some the whole head, and are often highly abstracted forms. Navajo masks appear to be inspired by the Pueblo prototypes.[31][32]
