METALWORKING AT MAYAPAN, YUCATAN, MEXICO: DISCOVERIES FROM THE R-183 GROUP

This article presents a compositional analysis of metal artifacts from the Postclassic period (a.d. 1100–1450) city of Mayapan, Yucatan, Mexico. We document metallurgical production at R-183, an elite residential group and one of the most significant archaeological contexts associated with metalworking at Mayapan. Salvage excavations in 1998 recovered a small cache containing 282 copper bells, two miniature ceramic vessels filled with metal, and production debris including loose casting sprues and miscast bells. Metallographic analysis of a small copper bell and wire fragments from the cache reveals lost-wax casting production techniques. X-ray fluorescence spectrometry (XRF) of metal artifacts provides insight into the range of metals used by the R-183 metalworkers, which included copper- lead, copper-tin, and copper-arsenic alloys, and how these alloys compare to assemblages recovered from other contexts at the city. Our findings strongly suggest the use of remelting and casting techniques, likely utilizing remelted metals of both West and central Mexican origin, together with the use of imported goods made from a range of copper alloys

Past fire dynamics inferred from polycyclic aromatic hydrocarbons and monosaccharide anhydrides in a stalagmite from the archaeological site of Mayapan, Mexico

Speleothems (cave stalagmites) contain inorganic and organic substances that can be used to infer past changes in local and regional paleoenvironmental conditions. Specific biomarkers can be employed to elucidate the history of past fires, caused by interactions among climate, regional hydrology, vegetation, humans, and fire activity. We conducted a simple solid–liquid extraction on pulverised carbonate samples to prepare them for analysis of 16 polycyclic aromatic hydrocarbons (PAHs) and three monosaccharide anhydrides (MAs). The preparation method requires only small samples (0.5–1.0 g); PAHs and MAs were measured by GC–MS and LC–HILIC–MS, respectively. Detection limits range from 0.05–2.1 ng for PAHs and 0.01–0.1 ng for MAs. We applied the method to 10 samples from a ∼ 400-year-old stalagmite from Cenote Ch'en Mul, at Mayapan (Mexico), the largest Postclassic Maya capital of the Yucatán Peninsula. We found a strong correlation (r = 0.75, p < 0.05) between the major MA (levoglucosan) and non-alkylated PAHs (Σ15). We investigated multiple diagnostic PAH and MA ratios and found that although not all were applicable as paleo-fire proxies, ratios that combine PAHs with MAs are promising tools for identifying different fire regimes and inferring the type of fuel burned. In the 1950s and 1960s, levoglucosan and Σ15 concentrations roughly doubled compared to other times in the last 400 years, suggesting greater fire activity at Mayapan during these two decades. The higher concentrations of fire markers may have been a consequence of land clearance at the site and exploration of the cave by Carnegie Institution archaeologists

Kukulcan's realm: urban life at ancient Mayapán

Includes bibliographical references and index.With contributions by Timothy S. Hare, Kukulcan's Realm chronicles the fabric of socioeconomic relationships and religious practice that bound the Postclassic Maya city of Mayapán's urban residents together for nearly three centuries. Presenting results of ten years of household archaeology at the city, including field research and laboratory analysis, the book discusses the social, political, economic, and ideological makeup of this complex urban center. Masson and Peraza Lope's detailed overview provides evidence of a vibrant market economy that played a critical role in the city's political and economic success. They offer new perspectives from the homes of governing elites, secondary administrators, affluent artisans, and poorer members of the service industries. Household occupational specialists depended on regional trade for basic provisions that were essential to crafting industries, sustenance, and quality of life. Settlement patterns reveal intricate relationships of households with neighbors, garden plots, cultivable fields, thoroughfares, and resources. Urban planning endeavored to unite the cityscape and to integrate a pluralistic populace that derived from hometowns across the Yucatan peninsula.--Provided by publisher.Chapter 1.

Metallurgical Ceramics from Mayapan, Yucatan, Mexico

Recent excavations at the Postclassic (AD 1050-1440) Maya site of Mayapan, Mexico, have uncovered a variety of metal objects, metal production debris, and ceramic objects that appear to be linked to metallurgical activities at the site. Our present study investigates a corpus of small ceramic objects to determine if these objects was used in metallurgical processes such as lost-wax casting. A variety of analytical techniques was utilized, including x-ray fluorescence, electron probe, petrography, and reflected light microscopy. Metal residues were detected on the surfaces of several objects, and copper prills were identified within the ceramic fabric, suggesting that the ceramics were exposed to liquid metal during remelting and/or casting events. A comparison of the microstructures of these metallurgical ceramics to typical ceramics from Mayapan demonstrates that the fabrics are very different, and suggests that the metallurgical ceramics were specifically engineered to function in the high temperature environment required for metallurgy. The distribution of metal and metallurgical ceramics across the site of Mayapan suggests that metal production activities may have been more widely distributed and practiced than earlier thought.

Blowpipes and their metalworking applications: New evidence from Mayapán, Yucatán, Mexico

© 2020 Meanwell et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. This study presents evidence of two tuyères, or blowpipe tips, used in metalworking at the Postclassic period city of Mayapán. Blowpipe technology has long been hypothesized to be the production technique for introducing oxygen to furnaces during the metal casting process on the basis of ethnohistorical depictions of the process in ancient Mesoamerica. To our knowledge, the tuyères recovered at Mayapán are the first archaeologically documented tuyères for pre-Hispanic Mesoamerica. The dimensions, internal perforation, vitrification, and presence of copper prills within the ceramic fabric, suggest that they were used in pyrotechnological production, likely metalworking, and is consistent with previous evidence for small-scale metalworking at Mayapán. Blowpipe use in metallurgical production is a logical extension of a much longer tradition of blowgun use in hunting, which was likely already present in Mesoamerica by the time metal was introduced to West Mexico from South America. Furthermore, the dimensions of the Mayapán tuyères are consistent with the internal diameter of ethnohistorically-documented blowguns from Jacaltenango in the southwest Maya region. We conducted replication experiments that suggest that when combined with wooden blowpipes, the Mayapán tuyères would have been ideal for small-scale, furnace-based metallurgy, of the type identified at Mayapán from Postclassic period contexts
