The organization of the vague Siouan thearchy appears to have varied from group to group. Among all of the tribes whose beliefs are known, the sun was an important wakanda, perhaps the leading one potentially, though usually of less immediate consideration than certain others, such as thunder, lightning, and the cedar tree; among the Osage the sun was invoked as "grandfather," and among various tribes there were sun ceremonials, some of which are still maintained; among the Omaha and Ponka, according to Miss Fletcher, the mythic thunder-bird plays a prominent, perhaps dominant rôle, and the cedar tree or pole is deified as its tangible representative. The moon was wakanda among the Osage and the stars among the Omaha and Ponka, yet they seem to have occupied subordinate positions; the winds and the four quarters were apparently given higher rank; and, in individual cases, the mythic water-monsters or earth-deities seem to have occupied leading positions. On the whole, it may be safe to consider the[pg 184] sun as the Siouan arch-mystery, with the mythic thunder-bird or family of thunder-birds as a sort of mediate link between the mysteries and men, possessing less power but displaying more activity in human affairs than the remoter wakanda of the heavens. Under these controlling wakandas, other members of the series were vaguely and variably arranged. Somewhere in the lower ranks, sacred animals—especially sports, such as the white buffalo cow—were placed, and still lower came totems and shamans, which, according to Dorsey, were reverenced rather than worshiped. It is noteworthy that this thearchic arrangement corresponded in many respects with the hierarchic social organization of the stock.

The Siouan thearchy was invoked and adored by means of forms and ceremonies, as well as through orisons. The set observances were highly elaborate; they comprised dancing and chanting, feasting and fasting, and in some cases sacrifice and torture, the shocking atrocities of the Mandan and Minitari rites being especially impressive. From these great collective devotions the ceremonials graded down through war-dance and hunting-feast to the terpsichorean grace extolled by Carver, and to individual fetich worship. In general the adoration expressed fear of the evil rather than love of the good—but this can hardly be regarded as a distinctive feature, much less a peculiar one.

Some of the mystery places were especially distinctive and noteworthy. Foremost among them was the sacred pipestone quarry near Big Sioux river, whence the material for the wakanda calumet was obtained; another was the far-famed Minne-wakan of North Dakota, not inaptly translated "Devil's lake;" a third was the mystery-rock or medicine-rock of the Mandan and Hidatsa near Yellowstone river; and there were many others of less importance. About all of these places picturesque legends and myths clustered.

The Siouan mythology is especially instructive, partly because so well recorded, partly because it so clearly reflects the habits and customs of the tribesmen and thus gives an indirect reflection of a well-marked environment. As among so many peoples, the sun is a prominent element; the ice-monsters of the north and the rain-myths of the arid region are lacking, and are replaced by the frequent thunder and the trees shaken by the storm-winds; the mythic creatures are shaped in the image of the indigenous animals and birds; the myths center in the local rocks and waters; the mysterious thearchy corresponds with the tribal hierarchy, and the attributes ascribed to the deities are those characteristic of warriors and hunters.

Considering the mythology in relation to the stages in development of mythologic philosophy, it appears that the dominant beliefs, such as those pertaining to the sun and the winds, represent a crude physitheism, while vestiges of hecastotheism crop out in the object-worship and place-worship of the leading tribes and in other features. At the[pg 185] same time well-marked zootheistic features are found in the mythic thunder-birds and in the more or less complete deification of various animals, in the exaltation of the horse into the rank of the mythic dog father, and in the animal forms of the water-monsters and earth-beings; and the living application of zootheism is found in the animal fetiches and totems. On the whole, it seems just to assign the Siouan mythology to the upper strata of zootheism, just verging on physitheism, with vestigial traces of hecastotheism.

SOMATOLOGY

The vigorous avocations of the chase and war were reflected in fine stature, broad and deep chests, strong and clean limbs, and sound constitution among the Siouan tribesmen and their consorts. The skin was of the usual coppery cast characteristic of the native American; the teeth were strong, indicating and befitting a largely carnivorous diet, little worn by sandy foods, and seldom mutilated; the hands and feet were commonly large and sinewy. The Siouan Indians were among those who impressed white pioneers by the parallel placing of the feet; for, as among other walkers and runners, who rest sitting and lying, the feet assumed the pedestrian attitude of approximate parallelism rather than the standing attitude of divergence forward. The hair was luxuriant, stiff, straight, and more uniformly jet black than that of the southerly stocks; it was worn long by the women and most of the men, though partly clipped or shaved in some tribes by the warriors as well as the worthless dandies, who, according to Catlin, spent more time over their toilets than ever did the grande dame of Paris. The women were beardless and the men more or less nearly so; commonly the men plucked out by the roots the scanty hair springing on their faces, as did both sexes that on other parts of the body. The crania were seldom deformed artificially save through cradle accident, and while varying considerably in capacity and in the ratio of length to width were usually mesocephalic. The facial features were strong, yet in no way distinctly unlike those found among neighboring peoples.

Since the advent of white men the characteristics of the Siouan Indians, like those of other tribes, have been somewhat modified, partly through infusion of Caucasian blood but chiefly through acculturation. With the abandonment of hunting and war and the tardy adoption of a slothful, semidependent agriculture, the frame has lost something of its stalwart vigor; with the adaptation of the white man's costume and the incomplete assimilation of his hygiene, various weaknesses and disorders have been developed; and through imitation the erstwhile luxuriant hair is cropped, and the beard, made scanty through generations of extirpation, is commonly cultivated. Although the accultural condition of the Siouan survivors ranges from the essentially primitive status of the Asiniboin to the practical civilization of the representatives of several tribes, it is fair to consider the stock in a[pg 186] state of transition from barbarism to civilization; and many of the tribesmen are losing the characteristics of activity and somatic development normal to primitive life, while they have not yet assimilated the activities and acquired the somatic characteristics normal to peaceful sedentary life.

Briefly, certain somatic features of the Siouan Indians, past and present, may be traced to their causes in custom and exercise of function; yet by far the greater number of the features are common to the American people or to all mankind, and are of ill-understood significance. The few features of known cause indicate that special somatic characteristics are determined largely or wholly by industrial and other arts, which are primarily shaped by environment.
