Long-distance provenance for obsidian artifacts of Mesoamerica Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park (Honduras)

Los Naranjos is one of the most important pre-Columbian human settlements of Honduras related to the south-easternmost border of the Mayan civilization. Although the archaeological site mostly spans from 850 BC to 1250 AD, the present obsidian study was only focused on the Preclassic and Early Classic periods (Jaral, 800–400 BC and Edén, 400 BC–550 AD) where undamaged blades and/or retouched obsidian flakes are rare. In this way, the INAA analyses of 17 obsidian samples, compared with major-trace elements data of Honduran and Guatemalan obsidian sources, are mostly representative of waste flakes. Lithic artifacts of Los Naranjos such as sandstones, basalts, and quartzites come from local geological outcrops; whereas, obsidian provenance has to be searched from sources which are located within a radius up to 300 km far away. San Luis, La Esperanza, and Güinope obsidian sources are located in Honduras while the three most exploited Highland Guatemalan obsidian outcrops, which have been dominating long-distance trade in the Maya area mostly for the Classic-Postclassic periods, are San Martin de Jilotepeque, El Chayal, and Ixtepeque. An Ixtepeque provenance, for all the investigated obsidian samples of Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park, was established, thus emphasizing a long-distance source (180 km). This also confirms that Ixtepeque represents the most important provenance of the obsidian artifacts found in archaeological sites of Western and Central-Western Honduras. The possible role played by some of the most important rivers of Guatemala and Honduras as waterway networks of transport was finally pointed out. New INAA chemical data from the Honduran obsidian source of La Esperanza (“Los Hoyos”, 4 samples) are also reported in this paper.     

Trade,tribute, and neutron activation: The colonial political economy of Xaltocan,Mexico

In Trade, Tribute, and Transportation, Ross Hassig argues that indigenous towns in the northern Basin of Mexico during the colonial period were largely self-sufficient. They traded with Mexico City mostly in elite goods, but for the most part they produced for their own subsistence or traded with nearby towns. Chemical characterization by instrumental neutron activation analysis (INAA) and portable X-ray fluorescence (pXRF) of ceramics and obsidian from post-conquest contexts in Xaltocan, a site in the northern Basin of Mexico, reveals that Hassig’s model is partly correct for describing Xaltocan. The town focused on trade with nearby towns and it produced some ceramics for local consumption. However, Xaltocan was hardly isolated and self-sufficient in the post-conquest period. Instead, the data suggest that the people of Xaltocan also obtained ceramics and obsidian from a greater variety of sources than under Aztec domination. Rather than being an isolated rural site, Xaltocan either increased its external connections and number of trading partners after the Spanish conquest, or it managed to obtain a greater variety of products than before through a bustling market system.     

Early Olmec obsidian trade and economic organization at San Lorenzo

The Olmec were the first complex society to develop in Mesoamerica between 1800 and 600 cal B.C. The earliest large Olmec center during this period was the archaeological site of San Lorenzo which emerged as Mesoamerica's first large ritual and political center between 1400 and 1000 cal B.C. San Lorenzo's growth as a prominent center included the development of long distance trade relationships with adjacent areas of Guatemala and highland Mexico. High precision chemical analysis of obsidian imported for use in the fabrication of cutting tools is used to reconstruct the growth, size and extent of San Lorenzo's interregional exchange networks with areas of Mexico and Guatemala where obsidian occurs as raw material. A total of 852 obsidian artifacts were analyzed to reconstruct changes in obsidian procurement between 1800 and 800 cal B.C. This represents one of the largest samples of sourced obsidian from a Mesoamerican site and it provides a comprehensive picture for the development of interregional trade networks for Mesoamerica's first large Olmec center.     

Iron Age Transformations at Mmadipudi Hill,Botswana: Identifying Spatial Organization Through Electromagnetic Induction Survey

Mmadipudi Hill (CE 550–1200) is an Iron Age site in east-central Botswana approximately 3 km west of Bosutswe, a major Iron Age trade center at the eastern edge of the Kalahari Desert. A 5,000-m² electromagnetic induction (EMI) survey conducted in 2011 revealed a cattle post arranged in the Central Cattle Pattern, including a central animal kraal with at least three clusters of houses flanking the eastern edge. A test trench confirmed the presence of a Taukome daga structure, possibly a house, 100–150 cm in depth. The EMI survey is one of, if not the first, archaeogeophysical surveys conducted in Botswana. It has proven invaluable as a means to understand the settlement organization and to pinpoint excavations to gain a more detailed understanding of the material culture. The perspective it offered on thorn brush fencing would not have been possible through excavation alone. Although small in scope, the test excavation yielded Taukome and Toutswe artifacts related to the larger sets of issues the Bosutswe region faced as Indian Ocean trade transformed the local political economy. The nature of the relationships between Bosutswe and its surrounding communities likely evolved due to the rise of a prestige goods economy, growing inequality, and environmental degradation around CE 1200. The occupation at Mmadipudi Hill would have immediately preceded these changes. By determining the spatial organization of Mmadipudi Hill, this article begins a crucial first step towards exploring what the local settlement pattern looked like prior to CE 1200 and understanding what the relationships among sites may have been.     

Special Studies: The Obsidian Trade at Isla Cerritos,Yucatán,Mexico

Abstract

Provenience analysis of a small sample of obsidian artifacts from Isla Cerritos, a Terminal Classic/Early Postclassic Itzá trading port on the north coast of Yucatán, indicates a wide range of raw material sources from Central Mexico to the Guatemalan Highlands. The overwhelming predominance of Central Mexican obsidian reinforces the notion that Isla Cerritos was the main trading port of Chichén Itzá. The analysis also provides an indirect approximation of the Itzá obsidian trade networks, which were heavily reliant on sources that may have been under the control of the Toltec capital at Tula.     

Cultural interactions during the Ubaid and Halaf periods: Tell Kurdu (Amuq Valley,Turkey) obsidian sourcing

In order to decipher cultural influences, the inter-regional contacts of the Tell Kurdu settlement have been investigated through obsidian sourcing for the Halaf and Ubaid phases (c. 5700–4300 cal. BC). The chemical composition of nine artifacts from three archaeological levels of the site have been determined and compared to source data obtained in our laboratory or available in the literature. Trace and major element analyses were performed respectively by inductively coupled plasma - mass spectrometry (ICP-MS) and atomic emission spectrometry (ICP-AES). The results assignments point out five distinct sources which highlight northwestward and eastward connections. Besides the “traditional” procurement areas (Göllü Dag and Nemrut Dag massifs; Bingöl region), the development of new exploitation centers (northeast Anatolia and northeast Van lake) is noteworthy. These results of obsidian provenances are compared to those of other raw materials and production originating from distant areas, in order to outline Tell Kurdu trade networks during the Halaf and Ubaid periods.     

Building Bundles,Building Memories: Processes of Remembering in Adena-Hopewell Societies of Eastern North America

Over the past 20 years, archaeologists have grown increasingly interested in exploring the relationships between humans and things. In part, this focus on materiality has been fueled by the integration of modern philosophical perspectives and considerations of non-Western ontologies and the New Materialisms. In North America, much emphasis has been placed on exploring the relational aspects of American Indian ontologies in the past and present. In this article, I build upon these perspectives by integrating memory as an important infrastructure through which these relationships are cast and maintained. I refer to these memory-based practices as processes of remembering. I argue that identifying these discursive memory processes provides an opportunity to refine how we understand objects like bundles and the social process of bundling—one way archaeologists have framed complex human/thing relationships. I use an Adena-Hopewell burial mound from the Middle Woodland period in Eastern North America (ca. 200 BCE–CE 500) as a case study to illustrate how societies during this era were, at least in part, organized and sustained through the rituals involved in revising bundles of ancestors, objects, and memories of human action. I argue that bundling assemblages of the past managed social dissonance by stabilizing or transforming perceptions of kinship in social coalitions.     

Towards a Multi-Agent-Based Modelling of Obsidian Exchange in the Neolithic Near East

This paper examines an alternative approach to previously proposed models of prehistoric exchange such as the law of monotonic decrement or the down-the-line exchange model developed by Renfrew (Proceedings of the Prehistoric Society 34: 319–331, 1968, Renfrew 1977) to explain the distribution of obsidian across the Near East during the Neolithic period. Renfrew’s down-the-line model, which results in a very regular and clustered network, does not permit the circulation of obsidian to regions of the Near East that are further than 300 km from the source zones, as is shown in the archaeological data available. Obsidian exchange is a complex system where multiple factors interact and evolve in time and space. We therefore explore Agent-Based Modelling (ABM) so as to get a better understanding of complex networks. ABM simulations of an exchange network where some agents (villages) are allowed to attain long-distance exchange partners through correlated random walks are carried out. These simulations show what variables (population density, degree of collaboration between villages…) are relevant for the transfer of obsidian over long distances. Moreover, they show that a type of small-world exchange network could explain the breadth of obsidian distribution (up to 800 km from source) during the Near Eastern Neolithic.     

The Lake Krasnoe obsidian source in Chukotka (Northeastern Siberia): geological and geochemical frameworks for provenance studies in Beringia

Basic data on the geology and geochemistry of obsidian from the Lake Krasnoe source in Chukotka (Northeastern Siberia) are reported for the first time. The data are based on 2009 fieldwork and analytical studies of igneous rock samples. The lake shore and surrounding parts of the Rarytkin Range were thoroughly examined. Two geochemical types of rhyolitic obsidian were recognized for the first time: (1) metaluminous obsidian related to the fine-grained crystalline rocks and (2) peralkaline obsidian corresponding to ignimbrite ash-flows or lapilli-tuffs composition. Both types are related to the final phase of acidic volcanism in the Western Kamchatkan-Koryak Volcanic Belt. Based on the results obtained, we conclude that accumulation of obsidian pebbles in the lake’s modern beach deposits is related to silicic melts that erupted during the late Eocene-early Oligocene in the form of extrusive domes or pyroclastic flows, which are now either covered by Quaternary sediments or located below the water level. The Lake Krasnoe obsidian was intensively used by the ancient populations of Chukotka as a raw material for making stone tools. It was also occasionally transported to Alaska across the Bering Strait in later prehistory. The distances between source and utilization sites are up to 700–1100 km. Geochemical data for Lake Krasnoe obsidian, based on neutron activation analysis and X-ray fluorescence that are presented here, can now be used for provenance studies in the Northeastern Siberia and adjacent regions of northern North America.     

Obsidian procurement,least cost path analysis,and social interaction in the Mimbres area of southwestern New Mexico

For over 15 years chemical compositional analyses of obsidian artifacts recovered from archaeological sites in the southwestern United States have been increasingly used to address many research agendas. Despite this increasing interest in obsidian studies, few have attempted to synthesize the ever-growing amount of data generated from the numerous projects being conducted in the southwest. Here, we synthesize and present data for 923 sourced obsidian samples recovered from over 80 archaeological sites in the Mimbres area of southwestern New Mexico. We then use least cost path analysis as a means of investigating procurement patterns as well as networks of social interaction within the region.     

Geochemical Variability in the Paredón Obsidian Source,Puebla and Hidalgo,Mexico: A Preliminary Assessment and Inter‐Laboratory Comparison

Chemical characterization reveals intra‐source variation in obsidian from the Paredón source area in Puebla and Hidalgo, Mexico. Two chemical sub‐sources of obsidian from Paredón are spatially discrete and cannot be distinguished by visual characteristics. To facilitate future investigations of the prehistoric exploitation of these sub‐sources, an inter‐laboratory comparison of elemental concentrations is presented based on neutron activation analysis and several XRF instruments.     

PARTICLE‐INDUCED X‐RAY EMISSION (PIXE) ANALYSIS OF OBSIDIAN FROM TEOTIHUACAN

A collection of 50 archaeological obsidian samples studied in the framework of the Preciudadela Project (Teotihuacan, Mexico) has been analysed using particle‐induced X‐ray emission (PIXE) with the external beam line of the Accélérateur Grand Louvre d'Analyse Elémentaire facility (C2RMF, Paris) and of the Instituto de Física (UNAM, Mexico). This work addresses the provenance of these obsidian samples, with the purpose of determining if they come from the obsidian sources exploited by Teotihuacans (mainly Otumba and Sierra de Pachuca), from other sources, or arrived via commercial exchanges with other regions. For that, the elemental compositions derived from the PIXE spectra have been compared with data published in the literature on the basis of instrumental neutron activation analysis. From the concentrations of selected key elements (Na, K, Mn, Fe, Zn, Rb, Sr, Zr), it was possible to unambiguously assign the provenance of most samples. Many originate from two major sources, namely Sierra de Pachuca (Hidalgo) and Otumba (Mexico), which were the main obsidian deposits used by the Teotihuacans. However, some samples exhibit a compositional fingerprint matching other provenances, i.e., Paredón (Puebla) and Zacualtipan (Hidalgo).     

Characterisation of obsidian subsource variability at El Paredón,Mexico

Portable X-ray fluorescence (pXRF) geochemical analysis on obsidian from five Formative period (1200 BCE to AC 100) sites from Tlaxcala, Mexico, has revealed that most of the material had similar values to those found in the closest obsidian source, named El Paredón, Puebla. Nevertheless, initial analyses did not resolve whether these materials came from the same caldera or from a specific obsidian deposit. Here we present a methodology that allows the identification of obsidian subsources. The results reveal that Tlaxcalan populations took advantage of a specific obsidian deposit called Tres Cabezas, Puebla, providing valuable new data to identify associated regional exchange networks.     

Provenance of prehistoric obsidian artefacts from Kul Tepe,northwestern Iran using X-ray fluorescence (XRF) analysis

Analysis by X-ray fluorescence of 53 obsidian artifacts the main source of obsidian for the workshops in Kul Tepe was Syunik but obsidian sources as far as west as the Lake Van region (Nemrut Da? and Meydan Da?) and as far north as Gutansar were also utilized. These new results indicate a broad network of trade and exchange.     

New investigations of the Göllüdağ obsidian lava flows system: a multi-disciplinary approach

The Göllüda? obsidian lava flow system is relatively complex. More than ten different obsidian outcrops and knapping workshops have been identified around this volcano. Their importance for long and short distances obsidian supply has already been demonstrated.One of the main problem encountered when studying the Göllüda? obsidian flows, is the great chemical similarity of some of them. The use of the geochemical approach to solve the problems of obsidian trade around the Göllüda? is therefore insufficient. A multi-disciplinary program joining archaeology, geochemistry and geomorphology, was thus started to understand the relationships between the different obsidian flows and to draw the pattern of the Göllüda? obsidian trade.Our archaeological and geomorphologic approach will help us to understand which obsidian outcrops were available during the Palaeolithic and Neolithic periods.Also our geomorphologic approach, linked to intensive geochemical analyses, will help us to understand the spatial variability of the geochemistry of the obsidian outcrops. Lithic technology will also give information about the different knapping methods used at the workshops.     

Age and exploitation of obsidian from the Medicine Lake Highland,California

The relationship between major and minor elements, trace element composition, and age of obsidian sources within a volcanic field, is of considerable interest for obsidian source and artifact research in the New and Old World. The present study investigates this relationship in the Medicine Lake Highland of western North America. Geological evidence had indicated a very young age for all obsidian sources in the Highland, yet archaeological evidence suggested that obsidian was utilized for several thousand years. X-ray fluorescence analysis distinguished the latest flow (Glass Mountain) from the Cougar Butte, Grasshopper Flat, and Lost Iron Wells sources. Data obtained from two nearby archaeological sites showed that obsidian from the latter two sources was used by c. 7500 bc, while Glass Mountain material was not used (or available) until after 1360± 240 bp. These findings indicate that inferences of an extremely recent age for all obsidian sources in the volcanic field were unwarranted. Further analysis of major and minor elements indicated different hydration rates for these sources. The results argue that significant geochemical variability, as well as age differences, can exist between obsidian sources within the same volcanic field.     

Domestic Faunal Assemblages from the Classic Period Valley of Oaxaca,Mexico: A Perspective on the Subsistence and Craft Economies

During the Classic period (ad 200–800), urban Monte Albán in the Valley of Oaxaca was one of the most monumental cities in Mesoamerica. Yet relatively little is known about the Classic-period economy that sustained this prehispanic centre. In this paper, we compare the faunal assemblages at two outlying Classic-period sites located in the central valleys of Oaxaca—Ejutla and El Palmillo. This analytical comparison provides a new empirical perspective on two important aspects of the ancient Oaxacan economy, subsistence strategies and household craft manufacture. Although Ejutla and El Palmillo have rather distinct environmental settings, the faunal component of the diet at the sites is found to be similar with some subtle differences. More marked distinctions between the sites are noted in the use of bone as a raw material for tools and ornaments. When the findings from the faunal comparison are situated within the context of other domestic remains from Classic-period Ejutla and El Palmillo, intraregional variation in household strategies of production and exchange is evidenced, providing a preliminary vantage on the complex economy that underlay this prehispanic polity.     

Prehispanic Dugout Canoes in Mexico: A Typology Based on a Multidisciplinary Approach

Navigation implies a deep knowledge of the environment in which it is practised as well as the development of correlated technologies and techniques. In fact, sailing in lakes, rivers, along coasts or in high seas requires specific skills. This is why watercraft reflect the specific expertise of cultures in relation to the available resources and materials. Navigation as a means of movement and boats as modes of transportation is a well-documented topic in Europe, Asia and the Pacific Ocean, whether focusing on antiquity or the present. Nonetheless, in the New World, especially in Mesoamerica where the Aztec, Tarascan and Mayan Empires flourished, indigenous maritime history has been thoroughly under-investigated. This article explores the first prehispanic dugout canoes of the region, based on a multidisciplinary approach for the Mexico and Pátzcuaro Basins, in the Late Postclassic period (AD 1325-1521). For the first time, a typology of these dugout types is proposed, with a discussion of the importance of dugout canoes as a means of transportation in Mesoamerican civilizations, where wheels and draught animals did not exist.     

De la caída de Tenochtitlán al decaimiento del Make Sicko Seedy de Carlos Fuentes: Ciudades en crisis,mundos por nacer

Carlos Fuentes's 1987 carnivalesque novel, Cristóbal nonato, criticizes Mexico's prehispanic past through a satire of Tenochtitlán-Mexico City in the neoliberal, postnational era. This study consequently juxtaposes criticism, theory, and analysis from both imperial Aztec Mexico and nationalist modern Mexico. While the bulk of this 600-page novel confronts readers with a highly negative (although often risible) view of both Mexicos, it ultimately leads to a happy ending with a didactic twist: If Mexicans will stop abandoning Mexico for the North or other green pastures, and instead stay in Mexico despite its many problems, they can turn things around by their altruism and their activist determination.     

Lifestyle,occupation, and whole bone morphology of the pre‐Hispanic Maya coastal population from Xcambó, Yucatan,Mexico

The present bioarchaeological study examines the external diaphyseal geometric properties of humeri, radii, femora and tibiae of the Classic period skeletal population of Xcambó, Yucatan, Mexico. The diaphysial proportions are evaluated using a biomechanical approach together with data from the material context and other osteological information. Our intent is to provide new answers to questions concerning lifestyle, domestic labour division and subsistence strategies of this coastal Maya settlement that was inhabited from the Late and Terminal Preclassic (300 BC–350 AD) to the Postclassic Period (900–1500 AD). Our results provide evidence for a marked sexual division of labour when compared with values from contemporaneous inland populations. The overall male and female loading patterns differ remarkably in terms of form and in bilateral comparison. A high directional asymmetry in the upper limbs is evident among males, a condition related to maritime transportation and trading activities. On the other hand, female upper limbs are characterized by very low side differences. Forces on the arms of women were probably dominated by food processing, in particular the grinding of grains or seeds. In the lower limbs, males show significantly higher anteroposterior bending strengths, which can be explained by greater engagement in transportation tasks and carrying heavy loads. In the course of the Classic period (350–900 AD), diachronic changes affect the male sample only, which suggests a shift of occupational pattern and physical demands. This shift, in turn, reflects Xcambó's changing role as the centre of a densifying settlement area and its place in the trading activities of northern Yucatan. Other topics of discussion relate to general regional trends and local prehispanic subsistence strategies. Our conclusions emphasize the value of geometric long bone analysis in the reconstruction of activity patterns and lifestyles in ancient coastal settlements. Copyright © 2007 John Wiley & Sons, Ltd.
