It has already been suggested that the simpler forms of pendants with plain surfaces may have had particular significance to their possessors, as insignia, amulets, or symbols, or that they may have received painted designs of such a character as to give significance to them. For ornament the natural or plainly polished surface of the shell possessed sufficient beauty to satisfy the most fastidious taste--a beauty that could hardly be enhanced by the addition of painted or incised figures. But we find that many of the larger gorgets obtained from the mounds and graves of a large district have designs of a most interesting nature engraved upon them, which are so remarkable in conception and execution as to command our admiration. Such is the character of these designs that we are at once impressed with the idea that they are not products of the idle fancy, neither is it possible that they had no higher office than the gratification of barbarian vanity. I have given much time to their examination, and, day by day, have become more strongly impressed with the belief that no single design is without its significance, and that their production was a serious art which dealt with matters closely interwoven with the history, mythology and polity of a people gradually developing a civilization of their own. Although these objects were worn as personal ornaments they probably had specialized uses as insignia, amulets, or symbols. As _insignia_, they were badges of office or distinction. The devices engraved upon them were derived from many sources and were probably sometimes supplemented by numeral records representing enemies killed, prisoners taken, or other deeds accomplished. As _amulets_, they were invested with protective or remedial attributes and contained mystic devices derived from dreams, visions, and many other sources. As _symbols_ they possessed, in most cases, a religious character, and were generally used as _totems_ of clans. They were inscribed with characters derived chiefly from mythologic sources. A few examples contain geometric designs which may have been _time-symbols_, or they may have indicated the order of ceremonial exercises. That these objects should be classed under one of these heads and not as simple ornaments engraved with intricate designs for embellishment alone is apparent when we consider the serious character of the work, the great amount of labor and patience shown, the frequent recurrence of the same design, the wide distribution of particular forms, the preservation of the idea in all cases, no matter what shortcomings occur in execution or detail, and the apparent absence of all lines, dots, and figures not essential to the presentation of the conception. In describing these gorgets I have arranged them in groups distinguished by the designs engraved upon them.[135] They are presented in the following order: The Cross, The Scalloped Disk, The Bird, The Spider, The Serpent, The Human Face,
