Masks and animal skins worn at dances are, of course, not confined to the use of primitive races, but have been employed since ancient days in every kind of masque, dance, and pantomime. Much might be written on their symbolic meaning, and attention may be drawn to the special instance of the festa asinaria of mediæval days at which dancers wore the heads of asses.

Besides the masks and animal skins, ordinary clothing was often made to represent special animals. For instance, at Athens, Artemis was worshipped in ceremonies at which young maidens attired in saffron gowns danced a particular movement and were called "bears."

The Royal family of Dahomey worship the leopard, and some of the king's wives are distinguished by the title of "leopard wives" and wear striped cloths to resemble the animal.

Many savages paint a rude picture of the animal they represent upon the clothes worn, and this is a special feature of some of the extraordinary snake dancers, especially amongst the Moquis.

These dances as well as those of the Hopis are expressions of clan totemism rather than of snake worship. Several figures in the Maya codices represent human beings, evidently personifying deities and wearing the symbolic masks of animal gods. One of the human figures in the Codex Cortesianus wears the mask of a snake. The Hopi usually carries only the head of the animal personified, but the Mexican dresses in the skin. In some examples the head-dress is most elaborate, the head being painted green, with open mouth and red lips dotted with black, two pendant white, tooth-shaped projections hanging from the upper jaw. From the mouth a red tongue lolls. The eye is oval, with curved lines drawn upon the pupil, and the whole is capped by a crescentic figure towering above the head. Three triangular-shaped plumes extend from the cap, and over the nose a red-coloured flap hangs. Though usually green, the heads are sometimes painted white or brown, but none is red or yellow. In the Hopi folk-tales it is said that the waters of the world come from the breasts of the great snake, and sometimes a female figure, bearing a snake as a head-dress, is symbolised with water flowing from her breasts. Another symbolic figure has a snake's body with curious markings and a head practically drawn in identical lines with that of a human being. No doubt this represents a man transformed into, or personifying, a snake. At any rate, he wears the mask and represents the feathered snake ceremonially.

A number of animals are represented in Tusayan ceremonials and are then called Katcinas, which means the supernatural being personified, as well as the dance or act of personification. Besides the coyote, the wolf, the cougar, the bear, the antelope, and the badger, which figure largely among the supernatural beings found in the Sia ritual, the hawk, the man eagle, the bee, butterfly, mountain sheep, and owl all play an important part in Tusayan ceremonial. No women wear Katcina masks in a Hopi ceremony, the female Katcinas being invariably represented by men. The masked dances amongst the Pueblos, in which animal personifications take place and masks are worn, are called Katcina dances. They take place between January and August.[18]

The following strange ceremony is practised by Mexicans and is not unlike the Hopi snake dance. It is celebrated once in every eight years about October or November.

After fasting for some days, says one who has seen the dance, the natives disguised themselves in all manner of animal and bird dresses, and came up dancing to the chosen spot where the rain-god had been placed before a pool of water in which live snakes and frogs were swimming. The Macateca, which may be rendered "those from Deerland," then seized upon the wriggling reptiles with the mouth, never touching them with the hand, and attempted to swallow them alive, dancing all the time. He who managed to swallow the first snake cried out, "papa, papa" and danced round about the temple. After two days of these extraordinary exertions a procession was formed and all marched slowly four times round the temple. Then came a feast of fruit and pastry which had been placed ready in baskets for the purpose, and the ceremonial was ended. The old men and women present, knowing that there would be no repetition of the dance for eight years, wept bitterly at the close of the performance.

In a festival in vogue among the Cholutecas, a slave of good figure, and no personal blemish, is dressed for forty days in the same animal skin and mask which represent the special god to be personified.

The dresses of the Moquis during their serpent dances are fashioned of painted cotton kilts, of a reddish-yellow colour, decorated with narrow bands of yellow and green, and bordered by a narrow black stripe. At the bottom is a fringe of small bells of lead or tin. A snake is painted in the folds of the kilt, covered with white spots and bordered by narrow white lines. The arms and legs of the dancers are naked, but dangling to their heels behind they wear skins of the fox or coyote.
