History and context

San Lorenzo occupied an elevation surrounded by rivers and floodable plains. Its inhabitants cut terraces, filled depressions and raised platforms: a social topography made with countless baskets of earth, long before Mesoamerican stone pyramids.

The effort reveals large-scale coordination, but not the organigram that directed it. Houses, maize crops, river routes and meeting spaces coexisted in a landscape where fertile water and dangerous floods were the same force.

The elevation of San Lorenzo was not simply a hill occupied: its inhabitants trimmed edges, levelled spaces and added fills to convert it into a habitable and ceremonial surface over the floodable plain. Each stage had to coordinate extraction, transport in baskets, compaction and drainage before receiving new constructions.

The rivers offered fertile soils and mobility, but also floods capable of isolating paths and eroding slopes. The monumental work was therefore a continual negotiation with water; its conservation depended less on a founding gesture than on many seasons of communal repair.

Evidence and interpretation

Documented fact: San Lorenzo was a major Early Formative centre, with platforms, terraces and earthworks in a fluvial environment. Interpretation and caution: the scale of the works indicates cooperation and hierarchy, but does not allow reconstruction of a State, an enslaved population or a unique authority. Documented expansion: San Lorenzo was a major centre of the Early Formative, with terraces, platforms and artificial modifications of the relief in a fluvial environment. Expanded interpretation and caution: The volume of earth proves coordinated labour, but does not identify who ordered it, whether it was compulsory or how tasks were distributed among households.

Tools and workshops near the capital

The productive landscape of San Lorenzo included Malpica U, on Zapote Hill. There, excavations in 2012 and 2013 identified tools and waste from an obsidian blade workshop beside an ancient river. Ann Cyphers' team studied these remains to reconstruct the manufacturing stages. San Lorenzo received obsidian from at least eleven distant sources, according to the research. This evidence adds specialists, cutting materials, and river connections to the monumental plateau, without assuming that every tool was produced in the rulers' precinct.
