SHIFTING ALLIANCES: EPICLASSIC AND EARLY POSTCLASSIC INTERACTIONS AT CERRO PORTEZUELO

Abstract

Abstract This analysis takes a diachronic view of Epiclassic and Early Postclassic period production and consumption patterns of diagnostic pottery complexes at Cerro Portezuelo. Stylistic and chemical characterization studies indicate a dramatic shift in the directionality and participation in pottery complexes through time throughout the Basin of Mexico. In the Epiclassic period, Cerro Portezuelo was a participant in a southern basin cultural complex. Early Postclassic pottery at Cerro Portezuelo indicates full participation in the Mazapan/Tollan pottery complex extending from Tula, through Teotihuacan, and into the southern Texcoco region. This study expands upon a previous compositional study of Cerro Portezuelo materials that indicate that Epiclassic and Early Postclassic pottery consumption was predominantly from local sources in the southeastern basin. The current study further identifies stylistic affiliations in decorated pottery types with neighboring areas within the basin and significantly increases the sample size for Epiclassic and Early Postclassic compositional data at Cerro Portezuelo.
