Marketplaces

Marketplaces are difficult to identify archaeologically. However, the Spanish reported a thriving market economy when they arrived in the region. At some Classic period cities, archaeologists have tentatively identified formal arcade-style masonry architecture and parallel alignments of scattered stones as the permanent foundations of market stalls. A 2007 study compared soils from a modern Guatemalan market to a proposed ancient market at Chunchucmil; unusually high levels of zinc and phosphorus at both sites indicated similar food production and vegetable sales activity. The calculated density of market stalls at Chunchucmil strongly suggests that a thriving market economy already existed in the Early Classic. Archaeologists have tentatively identified marketplaces at an increasing number of Maya cities by means of a combination of archaeology and soil analysis. When the Spanish arrived, Postclassic cities in the highlands had markets in permanent plazas, with officials on hand to settle disputes, enforce rules, and collect taxes.
