Attribute-Based Seriation of Postclassic and Early Colonial Sherd Collections from the Basin of Mexico

Abstract Seriation of ceramic collections based on diachronic changes in formal and surface treatment attributes offers advantages over type-based approaches when dealing with small collections. Individual attributes may be recordable where types (constellations of attributes) are not, increasing the quantity of chronological information that can be inferred. In addition, different classes of attributes (e.g., decorative, formal, surface treatment) highlight distinct processes and changes related to pottery production, consumption, and use, and provide a basis for finer-resolution seriation results. This paper outlines a procedure for attribute-based seriation analysis by detecting time-sensitive attributes and assigning sherd collections to temporal phases using clustering and ordination techniques, crosschecked with discriminant analysis. The results indicate a five-phase sequence for Middle-Late Postclassic and Early Colonial period collections from the Basin of Mexico (ca. A.D. 1200–1625).
