ABSTRACT This study seeks to provide new interpretations for the abstract and geometric Avery Engraved vessel motifs created by the prehistoric Caddo. I argue that certain motifs represent wings, feathers, and the Upper World, while other motifs act as locatives and are representative of the Lower World in the Caddo’s conception of a tiered universe. Given the nature of archaeological research, it is not possible to ascertain all of the implications, nuances, and complexities of the motifs that appear on Avery Engraved vessels. However, this study and others like it, which work to extrapolate the meaning of motifs through comparative analysis with representational engraved shell imagery and through the use of ethnographic and ethnohistoric data, can enrich our knowledge about how the Caddo rendered and communicated core beliefs in nonrepresentational ways.
