Sun worship plays a most important part in modern Tusayan ritual, and the symbol of the sun in modern pictography can not be mistaken for any other. It is a circle with radiating feathers on the periphery and ordinarily with four lines arranged in quaternary groups. The face of the sun is indicated by triangles on the forehead, two slits for eyes, and a double triangle for the mouth. This symbol, however, is not always used as that of the sun, for in the Oraibi _Powalawû_ there is an altar in which a sand picture of the sun has the form of a four-pointed star. The former of these sun symbols is not found on Sikyatki pottery, but there is one picture which closely resembles the latter. This occurs on the bowl illustrated in plate CLXI, _c_. The main design is a four-pointed star, alternating with crosses and surrounded by a zone in which are rectangular blocks. While the identification may be fanciful, its resemblances are highly suggestive. The existence of a double triangle adjacent to this figure on the same bowl, and its likeness to the modern mouth-design of sun pictures, appears to be more than a coincidence, and is so regarded in this identification. In the design shown in plate CLVIII, _a_, one of the elaborate ancient sun figures is represented. As in modern symbols, the tail-feathers of the periphery of the disk are arranged in the four quadrants, and in addition there are appended to the same points curved figures which recall the objects, identified as stringed feathers, attached to the blanket of the maid (plate CXXIX, _a_). The design on the disk is different from that of any sun emblem known to me, and escapes my interpretation. I have used the distribution of the feathers on the four quadrants as an indication that this figure is a sun symbol, although it must be confessed this evidence is not so strong as might be wished. The triangles at the sides of two feathers indicate that a tail-feather is intended, and for the correlated facts supporting this conclusion the reader is referred to the description of the vessels shown in plate CXXXVIII. It would appear that there is even more probability that the picture on the bowl illustrated in plate CLVIII, _b_, is a sun symbol. It represents a disk with tail and wing feathers arranged on the periphery in four groups. This recalls the sun emblems used in Tusayan at the present time, although the face of the sun is not represented on this specimen. There is a still closer approximation to the modern symbol of the sun on a bowl in a private collection from Sikyatki. In plate CLVIII, _c_, the sun's disk is represented with the four clusters of feathers replaced by the extremities of the bodies of four birds, the tail-feathers, for some unknown reason, being omitted. The design on the disk is highly symbolic, and the only modern sun symbol found in it are the triangles, which form the mouth of the face of the sun in modern Hopi symbolism.
