This paper uses plane pattern symmetries to describe the structural arrangement of motifs in Sikyatki-style patterns on textiles depicted in fourteenth and fifteenth century AD kiva murals from Awat'ovi and Kawaika'a in Arizona and Pottery Mound in New Mexico. The analysis reveals that these textiles have pattern structures in common with designs on textiles, ceramic artifacts, and architectural decorations in the Postclassic Mixteca-Puebla style. These shared patterns and pattern structures were introduced into the American Southwest woven on fabric structures of textiles brought north from Mesoamerica via trade and migration routes along the Mexican West Coast and through the Sierra Madre.
