Although the topic has received recent attention, relatively little is knownabout how pre-Hispanic Mesoamerican communities were internally organized andinterconnected. In this paper, we examine that question from the perspective ofthe Classic-period settlement of El Palmillo, in the Valley of Oaxaca, Mexico.Previous studies of the valley have postulated that communities often were (andstill are) subdivided into barrios, although the modes of integration for thosesegments are less fully defined. Along these lines, we have previouslyidentified commoner and higher-status houses at El Palmillo (along withassociated artifactual and architectural inventories). We also have noted thatdifferent commoner houses were involved in distinct suites of craft activity,thereby indicating a degree of economic interdependence among these units. Herewe expand our analysis to domestic offerings, which we found to vary across theexcavated houses. Adapting a perspective from Durkheim's distinctionbetween mechanical and organic solidarity, we find an expected organic(hierarchical) relationship between the offering assemblages of thehigher-status residences and the offerings in commoner house lots. At the sametime, we see another axis of variation in domestic offerings that appears moreorganic (nonhierarchical) in nature. The latter axis of variation at El Palmillohas a clear spatial component, in support of previous hypotheses that barrios orspatially defined social segments were important in Valley of Oaxacapre-Hispanic communities. At El Palmillo, the definitional features of thesesocial segments appear to have been ideological as well as economic.
