This dissertation is an archaeological study of the ancient settlement of Labna, a Lowland Maya community in the Puuc Region of Yucatan, Mexico. The form, layout, and architecture of Labna are representative of a large number of Maya centers. The architectural core is considered a model for studying ancient Maya social organization and reflects the debate among Mayanists about the mechanisms and principles that held together Maya communities and states. Analysis of form and layout, as well as of function and meaning of built spaces in Labna, indicates a stratified type of community, with an internal composition based on social units integrated by different organizational principles. This conclusion is based on comparisons of archaeological feature clusters on basal platforms, the remains of several types of roofed spaces on top of such platforms, and the presence/absence and location/distribution of underground cisterns for storing rain water (chultuns), and grinding stones for corn (metates). In the site center, architectural style, form, layout, and iconography were important sources for inferring chronological and functional information. Excavations that exposed the building sequence of structures forming the architectural core of the ancient community revealed several stages of development. Continuous growth and reorganization of the public buildings resulted in changes in form and function of built spaces. A diachronic approach for understanding core composition of the ancient community showed the dynamic nature in the layout of public architecture. The final layout of the urban core of Labna was the result of architectural programs conducted by several generations of rulers. The notion of sequential architectural programs and the identification of a particular form of built space as throne rooms provided a way to define temporal periods. The notion that throne rooms were manufactured in a sequential order in palace complexes, when combined with analysis of architectural styles, suggest three major building episodes, each probably related to a ruler. This dynamic perception of the social organization reflected in the layout of the site center is the result of a long term conjunctive study that included archaeological excavations, site and intersite settlement patterns, iconographic, geographical, and architectural approaches. / acase@tulane.edu
