This volume focuses on Teotihuacan, the most singular site in Mesoamerican archaeology, effected in a mode not seen elsewhere. The only city in Mesoamerica that represents an entire culture, Teotihuacan set itself apart from other cities in the same time period, acting as part of the foundation for our understanding of Mesoamerican cultures. The papers in this collection seek to explain the particular features that set it apart from other Mesoamerican places and cultural manifestations. Drawing on fields ranging from art history to political analysis, these essays provide a synthesis and new appraisal of Teotihuacan’s unique cultural manifestations and reflect a new stage in Teotihuacan studies.
