AbstractOne hundred and twenty years ago, the first obsidian implements were reported from Hopewellian mounds by Squier and Davis (1848). Since that time, a number of regions have been suggested as the source area: Alaska, the Pacific Coast, Yellowstone National Park, New Mexico, and central Mexico. Neutron activation analysis of the elemental composition of Hopewellian obsidian indicates two separate element groups. One of these, the 150 Group, has its source at Obsidian Cliff in Yellowstone. The second, the 90 Group, is also located in Yellowstone, but the exact flow has not yet been discovered.

Compositional Study

The question of spatial and temporal origins for Plumbate ware is addressed with archaeological evidence from the eastern Soconusco region of the Pacific slope, and evidence from a recent stylistic and compositional study (the latter by neutron-activation analysis). This evidence confirms the Pacific coastal-origins hypothesis proposed by Shepard (1948), suggesting specifically that the first Plumbate, designated "Guayabal Plumbate," was produced in or near the littoral zone of southwest Guatemala. The development of Early Postclassic Tohil Plumbate out of Late Classic San Juan Plumbate is found not to involve a hypothesized intermediate stage (designated "Robles" in previous literature). The fancy abstract-incised and effigy style associated with Tohil Plumbate is argued to represent a stylistic departure of a small group of ceramic artisans who previously had worked in a long-lived "background" tradition.

Exchange Relationships

Neutron activation analysis (NAA) of Coarse Orange jars demonstrates economic exchange among the Classic period political capitals of Totocapan, Matacapan, and Teotepec in the Tuxtla Mountains of southern Veracruz, Mexico. Matacapan, in particular, displays evidence of intensive pottery production at large workshops at the southern margin of the site. Comoapan (Area 411) and Area 199 present configurations of kilns, ceramic densities, and assemblage characteristics that suggest production for exchange beyond the site's boundaries. Both of these production facilities specialized in the production of Coarse Orange jars, a well-made and decorated utilitarian ceramic ware. While these products were traded to sites in the Tepango Valley, different paste recipes of the Coarse Orange type were also produced locally. Of broader concern, I examine the articulation of these regional exchange relationships with the interregional interactions previously documented among Tuxtlas groups and others in central Mexico and the Gulf Coast.
