Commoner-Shaped Patterns of Production and Exchange Under Aztec Domination: Chemical Characterization of Pottery from Xaltocan

Abstract Studies of pottery production and exchange under the Mexica (Aztec) empire have emphasized the role of elites, the constraints created by the market system, or the effects of persistent regionalism in shaping economic patterns. We build on those studies by emphasizing the role of commoners and how their decisions and strategies shaped pottery production and exchange after the formation of the Mexica empire. We present a neutron activation analysis of 111 pottery samples from Xaltocan, including a variety of decorated and undecorated serving vessels and utilitarian pottery from contexts that date to the Mexica empire. The chemical composition of the pottery indicates production of different types at Xaltocan, Cuauhtitlan, Tenochtitlan, Texcoco, Otumba, Chalco, and the southern basin of Mexico. While some types were produced at a variety of locales, a few of the types sampled were produced only or mostly at Xaltocan, including Red Ware, Aztec Polychrome, and Fabric Marked pottery. The findings suggest that commoners were actively copying or producing different types without elite or Mexica control, and that perhaps they preferred to use some locally produced types instead of pottery made elsewhere. The findings show the power of commoners in shaping their economic lives even under imperial control.
