Invited by José García Payón of the Instituto Nacional de Antropología e Historia to map the central part of El Tajin and to excavate stratigraphic pits for a ceramic sequence, the authors were able also to make considerable progress toward understanding the settlement pattern of this large site. Based on surface survey, intimate knowledge of the mapped area, and the excavations, it is proposed that El Tajin was a city as well as a religious center, with a large stratified population that included skilled artisans, merchants, priests, and administrators. Judging by sherd cover and stratigraphy, the city occupied at least 5 km2 during its maximum period, probably between A.D. 600-900.
