While simple swasticas are not found on any of the Sikyatki pottery, modified and compound forms are well represented. There are several specimens of figures of the Maltese cross, and one closely approximating the Saint Andrew's cross. It is scarcely necessary to say that the presence of the various kinds of crosses do not necessarily indicate the influence of Semitic or Aryan races, for I have already shown[151] that even cross-shape prayer-sticks were in use among the Pueblos when Coronado first visited them. TERRACED FIGURES Among the most common of all geometric designs on ancient Tusayan pottery none excel in variety or number those which I place in the above group. They form the major part of all decoration, and there is hardly a score of ornamented vessels in which they can not be detected. In a typical form they appear as stepped designs, rectangular figures with diagonals continuous, or as triangular designs with steps represented along their sides. While it is probable that in some instances these figures are simply decorative, with no attempt at symbolism, in other cases without doubt they symbolize rain-clouds, and the same figures are still used with similar intent in modern ceremonial paraphernalia--altars, mask-tablets, and the like. Decorative modifications of this figure were no doubt adopted by artistic potters, thus giving varieties where the essential meaning has been much obscured or lost. THE CROOK Among the forms of geometric designs on ancient Tusayan pottery there are many jars, bowls, and other objects on which a crook, variously modified, is the essential type. This figure is so constant that it must have had a symbolic as well as a decorative meaning. The crook plays an important part in the modern ritual, and is prominent on many Tusayan altars. Around the sand picture of the rain-cloud, for example, we find a row of wooden rods with curved ends, and in the public Snake dance these are carried by participants called the Antelopes. A crook in the form of a staff to which an ear of corn and several feathers are attached is borne by _katcinas_ or masked participants in certain rain dances. It is held in the hand by a personage who flogs the children when they are initiated into certain religious societies. Many other instances might be mentioned in which this crozier-like object is carried by important personages. While it is not entirely clear to me that in all instances this crook is a badge of authority, in some cases it undoubtedly represents the standing of the bearer. There are, likewise, prayer offerings in the form of crooks, and even common forms of prayer-sticks have miniature curved sticks attached to them.
