Metallurgy in pre-Columbian Mesoamerica


The emergence of metallurgy in pre-Columbian Mesoamerica occurred relatively late in the region's history, with distinctive works of metal apparent in West Mexico by roughly AD 800, and perhaps as early as AD 600. Metallurgical techniques likely diffused northward from regions in Central or South America via maritime trade routes; recipients of these metallurgical technologies apparently exploited a wide range of material, including alloys of copper-silver, copper-arsenic, copper-tin and copper-arsenic-tin.

Metal items crafted throughout Mesoamerica may be broken into three classes: utilitarian objects, objects used for individual ornamentation, and ceremonial/ritual objects. The latter two categories comprise the bulk of distinctly Mesoamerican artifacts, with metals playing a particularly important role in the sacred and symbolic cultural realms.

Owing largely to its proximity to southern centers of metallurgy (specifically southern Central America and South America), the Southern Maya area appears to have been an early locus of metal working in Mesoamerica.

As with the Southern Maya area, the number and diversity of metal artifacts recovered from West Mexico indicates that this region was a regional nucleus of metallurgy, from which elements of technique, form and style could have diffused throughout Mesoamerica.

West Mexican smiths worked primarily in copper during the initial period, with some low-arsenic alloys, as well as occasional employment of silver and gold. Lost-wax cast bells were introduced from lower Central America and Colombia during this phase, along with several classes of cold-worked ornaments and hand tools, such as needles and tweezers. The prototypes for these small, often utilitarian items appear rooted in southern Ecuador and northern Peru. Small copper rings, generally found in burial contexts, are also common to Ecuador and Western Mexico and are abundant during this phase.
