Next, I provide 1\7 an updated interpretation of site chronology and apply it to a reconstruction of the occu pational history of Tres Zapotcs. This recon struction provides the basis for the subsequent discussion of continuity from Olmec to Epi Olmcc culture and the evolution of political organization at Tres Zapotes. I conclude with a model of political evolution that takes into account the ecological setting of Tres Zapotes, the history of regional political and economic systems, and the development of new forms of political expression. History of Research Tres Zapotes first attracted scholarly attention in 1869 when Jose Melgar reported the dis covery of a colosscll head by a compesino on the Hacienda Hucyapan (fig. i). Seventy years later, in 1939, Matthew Stirling initiated the first modern exploration of an Olmec site at Tres Zapotes. His discovery of Stela C, and Marion Stirling's reconstruction of a Cycle 7 baktun coefficient for its inscribed Long Count date, provided early support for a Formative placement of Olmec culture [fig. 2) (Stirling 1940). Working with Stirling, Philip Drucker [19431 conducted the first stratigraphic exca vations in an Olmec center and worked out a general ceramic chronology, later revised by Michael Coe in 1965 and refined by Ponciano Ortiz in 1975. The stone monuments of Tres Zapotes, which now numher more than forty, have been the subiect of several studies (Porter 1989), including Howell Williams' and Robert Heizer's (196 sllandmark petrographic c1l1alysis, and the obsidian assemhlage of the site was one of the first in Mesoamerica to he characterized hy physicochemical means [Hester et al.

As a result, scholars have underapprcci cally diverse setting provided the people of Tres period, ~tooe ated the significance of variation in the regional Zapotes with most of the resources they settings of heartland Olmec sites. required for their basic livelihood. The lclkes and swamps of the Papaloapan basin teemed 138 POOL with aquatic resources, and the alluvial plain argued that the distribution of major Olmec provided vast expanses of fertile agricultural centers and their association with specific sets land.
