THE STUDY OF ACTIVITIES IN CLASSIC HOUSEHOLDS Two case studies from Coba and Teotihuacan

Mesoamerican household sites were often deserted gradually, leaving very little de facto refuse for analysis. Starting with archaeological and paleobiological distribution patterns, this study adds a new dimension to the spatial study of two Classic households by plotting chemical concentrations in probable activity areas. The study of activity areas and domestic structures has become a fertile field of archaeological research. Yet, in some cases, this boom has also led to careless analyses of data. Though drawn from examinations of household structure, conclusions about surface distributions of artifacts and domestic mounds do not often rest on firm functional, contextual, social, or chronological evidence. Suppositions about elite versus common items, residential versus storage or cult architecture, have yet to be tested rigorously. Worse still, the archaeological literature consistently confuses refuse areas with workshops, common domestic structures with high status residences, and administrative sectors with residential areas. The result: small-scale excavations of floors have provided a voluminous number of untested and debatable hypotheses concerning household size, the degree of cooperation between families, and the developmental cycle of the unit, without, however, benefiting from a full understanding of the activity repertoire, its spatial distribution, the functions of particular structures, and the spatial limits of domestic
