The human figure described under costume (p. 100, Fig. 121) is a somewhat conventionalized realistic form indicated by incisions on one surface of a piece of antler 2 to 5 mm. thick.[389] It was found in the grave of an infant under the vertebrae, No. 25 in a dome of volcanic ash. It is of good technique and artistic execution. The eyes are of the shape of a parallelogram with rounded corners. These, with similarly shaped figures on the headdress or inner hair-rolls, and on the hands, knees, and insteps, slightly resemble a motive common in the art of the coast to the northwest. The crescent-shaped mouth and thick lips are indicated by incised lines, while the cheeks are full, and the entire head is somewhat set out in relief from the rest of the object. The radiating figures above the head do not represent feathers in a realistic way, but closely resemble the conventional paintings made by the Dakota on buffalo robes. These paintings have been called sun symbols, but are interpreted by the Dakota as the feathers of a war-bonnet or other headdress. The fingers and thumb are set off from the palm by two lines, which, with the mark at the wrist, make a figure resembling the eye-form so common in Northwest coast art. The concentric design on the knees is probably related to the wheel, sun, or spider-web pattern common as a symbol on the shirts, blankets, and tents of some Plains tribes. The feet jutting out at the sides are slightly wider than the legs. The inside of the foot is straight with the inside of the leg, while the outer part is curved. The two, taken together with the lower portion of the legs, resemble a divided hoof. The divided hoof is a common design among Plains tribes. [389] First described and figured, Smith, (g).
