The material at hand adds nothing new to the theory of the evolution of the terraced ornament from basketry or textile productions, so ably discussed by Holmes, Nordenskiöld, and others. When the Sikyatki potters decorated their ware the ornamentation of pottery had reached a high development, and figures both simple and complicated were used contemporaneously. While, therefore, we can so arrange them as to make a series, tracing modifications from simple to complex designs, thus forming a supposed line of evolution, it is evident that there is no proof that the simplest figures are the oldest. The great number of terraced figures and their use in the representation of animals seem to me to indicate that they antedate all others, and I see no reason why they should not have been derived from basketry patterns. We must, however, look to pottery with decorations less highly developed for evidence bearing on this point. The Sikyatki artists had advanced beyond simple geometric figures, and had so highly modified these that it is impossible to determine the primitive form. As I have shown elsewhere, the human hand is used as a decorative element in the ornamentation of the interior of several food bowls. It is likewise in one instance chosen to adorn the exterior. It is the only part of the human limbs thus used. Figure 354 shows the hand with marks on the palm probably intended to represent the lines which are used in the measurement of the length of pahos or prayer-sticks. From between the index and the middle finger rises a line which recalls that spoken of in the account of the hand on the interior of the food bowl shown in plate CXXXVII. [Illustration: FIG. 354--Human hand] The limb of an animal with a paw, or possibly a human arm and hand, appears as a decoration on the outside of another food bowl, where it is combined with the ever-constant stepped figure, as shown in figure 355.
