San Lorenzo

1400 BCE – 900 BCE (approx.) · capital San Lorenzo

The earliest great Olmec centre, on the Coatzacoalcos river, where colossal stone heads and the first large-scale planned settlement in Mesoamerica appeared.

Origins

Farming villages on a raised plateau above the Coatzacoalcos river floodplain in southern Veracruz grew into a major centre from about 1400 BCE. Control of fertile levee land and river trade routes allowed an elite to emerge, and by 1200 BCE San Lorenzo was the largest settlement in Mesoamerica.

Rule and society

Its rulers are known only through sculpture: ten colossal basalt heads, thought to be portraits of chiefs, and large table-thrones. Basalt was hauled from the Tuxtla Mountains some 60 kilometres away, showing great command of labour. The plateau was artificially levelled and fitted with stone drains. Obsidian, magnetite and fine pottery moved through wide exchange networks.

Decline and legacy

Around 900 BCE San Lorenzo declined, possibly through river shifts or political change, and many monuments were deliberately defaced and buried. Leadership of the Olmec world passed to La Venta. Its sculptural style shaped later Mesoamerican art and kingship.
