Early Maya Ritual Practices and Craft Production: Late Middle Preclassic Ritual Deposits Containing Obsidian Artifacts at Ceibal,Guatemala

This article examines Preclassic Maya ritual practices and craft production by means of a study of ritual deposits containing obsidian artifacts dated mostly to the late Middle Preclassic period (700–350 b.c.) at Ceibal, Guatemala. New ritual practices developed at Ceibal during this period, possibly through political interactions and negotiation involving emerging elites and other diverse community members. Common objects in ritual deposits in the public plaza shifted from greenstone celt caches to other artifacts, including those made of obsidian. The inhabitants of Ceibal engaged in various kinds of craft production, including the manufacture of obsidian prismatic blades. They also conducted public rituals in the Central Plaza, depositing exhausted polyhedral obsidian cores and other artifacts with symbolic significance in caches and as offerings in incipient elite burials and interments of sacrificed individuals. These cores clearly demonstrate the use of a sophisticated blade technology. Like greenstone objects, exhausted polyhedral obsidian cores deposited in cruciform arrangements along the east–west axis of the central E-Group plaza were used as symbols and markers of the center and four cardinal directions within the Maya cosmos. Public rituals were important for creating collective identities and for processes of political negotiation within the community. Emerging elites likely came to play an increasingly important role in public rituals as principal performers and organizers, setting the stage for later public events centered on rulers.     

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.     

Stable Isotopic Evidence of Ancient Maya Diet at Caledonia,Cayo District,Belize

The skeletal remains of 18 individuals interred at the ancient Maya site of Caledonia (100 to 1000 C.E.), located in the Cayo District of Belize, w ere sampled for stable carbon and nitrogen isotope analysis in order to reconstruct their diet. Stable carbon and nitrogen isotope ratios in 18 bone collagen samples and stable carbon isotope ratios in bioapatite from 15 bone and 6 tooth enamel samples were assessed. Small sample sizes precluded the assessment of dietary variation with respect to age, sex, social status or time period among the Caledonia Maya. However, the sampled individuals consumed a varied diet consisting of maize, supplemented with some C₃ plants, terrestrial herbivores and/or lower order freshwater resources such as snails and molluscs and possibly maize‐fed animals. This dietary variability with an emphasis on maize is unsurprising given the biological diversity surrounding the site and the known importance of this crop to the ancient Maya. As expected, the isotopic values from Caledonia are similar to those from nearby sites from similar time periods. However, four individuals exhibit a marine dietary signature, possibly indicating inland trade of marine resources from coastal sites, or the migration of coastal people to Caledonia. This study demonstrates the validity of sampling small, fragmented collections from minor Maya centres in order to gain valuable insight into ancient Maya dietary practices.

On the provenience of wood used in the manufacture of snuff trays from San Pedro de Atacama (Northern Chile)

The consumption of hallucinogenic substances is a long-standing tradition in the Americas. San Pedro de Atacama (SPA) in Northern Chile is the archaeological zone with the highest incidence of snuffing implements in the world. Snuff trays from SPA have been studied under a variety of prisms but their provenience, in particular that of the wood used in their manufacture, has not yet been addressed. The delicate nature of trays and their excellent state of preservation call for the use of non-invasive analytical methods. Wood density was used to demarcate a possible range of species and hence as a broad provenience marker, and its value determined for 169 trays from the museum at San Pedro de Atacama. The results showed that although some of the SPA snuff trays studied may have been manufactured with local wood, most of them used exogenous wood as raw material. At this point, it is not possible to ascertain the precise origin of such wood, but Bolivia and NWA appear as likely candidates. Three distinct styles have been defined for SPA trays: Tiwanaku, San Pedro, and Circumpuneño (encompassing the area around the Puna de Atacama and including SPA). The effect of style on density points to different sources of wood in Tiwanaku style trays and trays in San Pedro and Circumpuneño styles. As expected from geographically and temporally dynamic patterns of interaction of SPA with neighboring regions, diachronic differences in wood density distributions were found. Tray manufacturing technique was not dependent on wood density, suggesting that the skill of artisans and the quality of their tools allowed them to use any type of wood for their art work, independent of its complexity.     

The Archaeology of the Battle of Vuelta de Obligado,Buenos Aires Province,Argentina

Abstract

This paper presents the results of research carried out for more than a decade at Vuelta de Obligado, San Pedro, north-east of Buenos Aires province. The objectives were to understand the dynamics of the strategy followed on the 1845 battlefield by the two groups who fought (Anglo-French and Argentine), and to assess the impact of formation processes on the results produced. This has been achieved through the use of several sources of information: the archaeological record, written documents, Argentine and European plans and sketches, as well as data provided by the current population.     

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.     

Temporal frequency distributions of alluvium in the American Southwest: taphonomic,paleohydraulic, and demographic implications

The use of radiocarbon frequency distributions to reconstruct prehistoric human and animal populations must account for taphonomic loss and other factors that affect the archaeological and paleontological records. Surovell et al. (JAS, 36, 1715–1724) have recently proposed a correction for “taphonomic bias” that is based on the radiocarbon frequency of a global sample of volcanic deposits. Analysis of 717 radiocarbon dates sampled from the alluvium of the San Pedro and Santa Cruz rivers and their tributaries in southeastern Arizona shows that discovery and scientific biases also play an important role in the creation of radiocarbon frequency distributions, and that the rate of “taphonomic bias” in prehistory is not predicted by the radiocarbon frequency of volcanic deposits. The latter principle is further argued using a sample of 123 Pliocene to Clovis-age proboscideans from the San Pedro Valley. We propose an alternative model that is based on the nature of the stratigraphic record, with discovery bias, scientific bias, taphonomic loss, and the shape of the calibration curve all operating to influence the temporal frequency distribution of radiocarbon-dated prehistoric phenomena.     

A double dog burial from San Nicolas Island, California, USA: osteology, context, and significance

Recent archaeological excavations on San Nicolas Island, located off the coast of southern California, revealed the remains of a double dog burial interred sometime during the 13th and 14th centuries. Two carefully laid to rest and possibly sacrificed juvenile, female domestic dogs (Canis familiaris) between the ages of 1 and 6 months were found within a Native American village. Digestive tract residues include burned and unburned fish and marine mammal bone that suggest scavenging behavior or direct feeding by humans. Breed classifications place it between the Short-Nosed Indian dog and the Plains-Indian dog, likely representing a cross between those and other varieties of North American dogs. Comparisons with other dog burials from archaeological sites across southern California suggest commonalities and possible cultural linkages.     

Traditional Burnt-Lime Production at Mayapán,Mexico

Abstract

Lime was widely utilized throughout ancient Mesoamerica. Drawing on the expertise of traditional Maya lime producers from a small local community, we address the energetics, material inputs, and archaeological signature of burnt-lime production in the Northern Yucatan Peninsula of Mexico. When compared with the estimated lime usage at the Maya site of Mayapan, the data collected from experimental lime burning suggest that traditional lime production was reasonably labor intensive and used large, albeit sustainable, quantities of raw materials, especially wood. Lime manufacture was an important component of ancient Mesoamerican economic life, especially in urban settings where it may have been a full time occupation for some, at least during certain parts of the year. This analysis allows us to predict what the remains of lime burning sites should look like and where they are most likely to be encountered archaeologically.     

From Crafting to Caching: Technological and Iconographic Analyses of Blue Creek Cache 37

This paper presents technological and iconographic analyses of a Late Classic (a.d. 600–830) lithics cache recovered from the ancient Maya site of Blue Creek, Belize. The cache consisted of 21 obsidian prismatic blades and a number of chert artifacts, including 21 stemmed bifaces, a large laurel leaf biface, and a tridentate eccentric. The technological analysis of the stemmed bifaces identified three distinct stem production techniques that may be attributable to a combination of idiosyncratic knapping gestures and laterality, or handedness. A survey of Maya iconography demonstrated that large laurel-leaf bifaces and tridentate eccentrics occur in scenes depicting sacrifice and the burning of human remains, often by ritual specialists titled ch’ajoom, or “person of incense.” It is suggested that the presence of a large laurel-leaf biface and tridentate eccentric in the cache may indicate that Blue Creek was the residence of ch’ajoom at some point during the Late Classic period.     

Increasing data (INAA) on Ecuadorian obsidian artifacts: preliminary provenance and a clue for pre-Columbian eastward trade

In this work we carried out INAA major (Na, K, Ca and Fe %) and trace (ppm) elements (plus Mn by FAAS analysis) of 15 obsidian samples (waste flakes) coming from an unknown archaeological site (¹⁴C-AMS age of 1425 AD) located on the south-eastern flank of the back-arc Sumaco volcano (to the east of the Cordillera Real) and from two already known pre-Columbian archaeological localities: La Florida (Quito) and Milan (Cayambe). Literature compositional data of the Ecuadorian obsidian outcrops provide some constraints on the provenance of the analyzed waste flakes, even though different methods of analyses make comparisons a difficult task. Concerning the obsidian artifacts of La Florida and Milan, they come from the well known Sierra de Guamanì obsidian sources (Cordillera Real). By contrast, the obsidian fragments of the Sumaco settlement show some compositional characters compatible with obsidian erratic pebbles recently discovered in some river banks of the Amazonian foothills draining the easternmost flanks of the Antisana volcano in the Cordillera Real as well. In this way, the obsidian artifacts found at the Sumaco site reinforce the opinion that Ecuadorian source inventory is not yet exhaustive. Although the Antisana volcano seems to be the best candidate to find out additional primary outcrops of obsidian sources, it cannot be also excluded that sub-Andean and Amazonian people directly took advantage from obsidian secondary sources (e.g. river banks), rather than procurements from primary outcrops in the Cordillera Real. The new archaeological findings at the Sumaco volcano are really of paramount importance in tracing the ancient routes of a possible obsidian eastward trade toward the Amazonian region.     

The Hungarian and Slovak sources of archaeological obsidian: an interim report on further fieldwork,with a note on tektites

This report describes the results of fieldwork carried out in the Zemplén Mountain area of north-eastern Hungary in 1975. The aim of this work was to locate and sample geological sources of obsidian which may have been used by prehistoric man. These sources are of increased importance since the work of Nandris (1975) showed that the Romanian “sources” do not produce workable obsidian. During the fieldwork three sources in Hungary were visited and sampled; one of these was the previously unlocated source of Csepegö Forräs. A number of other possible localities for geological obsidian are mentioned in 19th and 20th century geological and archaeological literature, and the present state of knowledge with regard to these is summarized. Further sources exist in central and in south-eastern Slovakia. These sources were not visited but material has been obtained from both areas. The central Slovak sources do not produce workable obsidian and are not therefore relevant to archaeological studies. Obsidian from three localities in south-eastern Slovakia is of good glassy quality and further fieldwork is now needed to check the validity of these localities as geological sources. Reference is made to obsidian sources in the western U.S.S.R., and the problem of the use of tektites in archaeological sites is discussed.The obsidian samples obtained during this work are currently being analyzed using neutron activation, in order to characterize the sources on the basis of their trace element analysis and thus to relate them to archaeological obsidian from central and eastern Europe.     

Assessing the applicability of portable X-ray fluorescence spectrometry for obsidian provenance research in the Maya lowlands

Recent innovations in portable energy-dispersive X-ray fluorescence (PXRF) spectrometry have increased its utility for the geochemical characterization of obsidian artifacts for archaeological provenance research. However, concerns over the utility of PXRF instrumental analyses have been raised, focused on the validity and reliability of the geochemical data produced. Here we adopt the framework of Richard Hughes (On Reliability, Validity, and Scale in Obsidian Sourcing Research, 1998), whereby reliability addresses instrument stability and issues of measurement while validity pertains to an instrument’s ability to discern geochemical source provenance. This is done in order to test the utility of PXRF instruments for archaeological provenance research. k-Means cluster analysis was used to test the accuracy of PXRF through statistical comparison of data acquired via laboratory and portable energy-dispersive XRF instruments. Multivariate analysis was employed to demonstrate obsidian source representation at two Classic Maya archaeological sites in southern Belize – Uxbenká and Ek Xux – and to test the validity of data obtained from a PXRF instrument in answering archaeological research questions pertaining to regional interactions between lowland Maya polities. Results suggest that portable XRF instruments produce internally consistent results. However, data acquired from a PXRF instrument are not statistically equivalent to other XRF instruments. This is to say that while PXRF is not a reliable technique, it is valid for questions pertaining to geochemical source representation.     

‘Marineness’, the Underwater Seascape and Variability in Maritime Adaptations in the Late Ceramic Age Northern Lesser Antilles

ABSTRACT

To investigate potential variation between the fishing practices of contemporaneous Late Ceramic Age villages in the northern Lesser Antilles, we model expectations for each site based on local marine habitat and bathymetry and compare them to observed differences in zooarchaeological assemblages. The predictive model approximates which taxa were the most likely to have been targeted by fishers from each site, assuming that the majority of fishing likely occurred within short distances from each settlement. A comparison of expectations and archaeological observations is used to expose potential differences between sites in preferred fishing areas and techniques, preferred foods, or social distinctions. This variability is argued to reflect a fishing community’s ‘marineness’, or the interrelationship members have with the unique composition of marine resources and underwater seascape adjacent to their villages.     

Dietary Stress and Animal Resource Use at the Postclassic Maya city,Mayapán (Mexico)

ABSTRACT

Environmental changes resulting in drought and reductions in the availability of animal resources during the Late Classic Maya have been linked with the Maya ‘collapse’. Decreases in availability of dietary staples such as artiodactyls, and particularly white-tailed deer, during the Late Classic period would have placed food stress on populations during later periods. To test this hypothesis, here bone breakage patterns are examined at the Postclassic Maya city, Mayapán, to assess whether artiodactyl bones were being intensively processed for bone fats (marrow and grease). Fragmentation morphology, size and surface markings, along with skeletal part representation and distribution of large mammal bones were recorded for bone assemblages from several houselots. Evidence suggests the Maya were likely utilising bone marrow from artiodactyls but not intensively and they were not extracting bone grease. These results indicate that decreased accessibility to artiodactyls during the Postclassic was not causing high levels of dietary stress for the Maya at Mayapán, which is consistent with recent evidence demonstrating dietary consistency during the Postclassic in northern Yucatan.     

Measuring prehistoric mobility strategies based on obsidian geochemical and technological signatures in the Owens Valley,California

We compare the organization of obsidian flaked stone technologies in two different time periods at CA-INY-30, a village site in southern Owens Valley, eastern California. Previous archaeological studies suggest a reorganization in settlement patterns between the Newberry (ca. 3500–1500 BP) and Marana (ca. 650-contact) periods, from a highly mobile to a more residentially sedentary one. New geochemical data, based on laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analyses of obsidian artifacts associated with discrete house floors, support this basic settlement model, but reveal new detail in how people moved across the landscape and accessed, extracted, reduced and used obsidian resources. In the earlier Newberry period, there is no relationship between flake size and distance-to-source, and the falloff curve relating frequency of obsidian against distance is more gradual, as expected, but contrary to our expectations, source diversity is not higher. These factors suggest extremely high mobility, but also selective extraction of particular sources. Newberry obsidian may have been acquired by groups of hunters who embedded quarrying within long-distance trips to distant hunting grounds, and subsequently transported bifacial cores to base camps. By contrast, Marana patterns show strong relationships between flake size and distance from source and steeper fall-off curves, suggesting groups acquired their obsidian primarily from closer sources, likely via exchange networks. At the same time, geochemical diversity, especially among smaller resharpening flakes, is higher in the Marana period, highlighting the wide-ranging conveyance systems through which obsidian moved.     

Classic Lowland Maya Political Organization: A Review

This paper reviews recent archaeological research concerning Classic Maya lowland political systems (ca. A.D. 250–1000). It focuses specifically on (1) subsistence practices revealed through the analysis of prehistoric climate, available resources, agricultural technologies, and diet; (2) population distribution, density, and size revealed through the analysis of settlement practices and architectural function; (3) social differentiation and interaction revealed through the analysis of burial practices, diet and health, architecture, and production, consumption, and exchange patterns; and (4) ancient Maya political economy (how it was funded) revealed through the analysis of community organization, ritual activities, the Classic Maya collapse, and warfare. It finally ends with a brief discussion of the future of Maya archaeology. A key factor that recurs throughout this review is the noticeable amount of variability that existed—varied resources, subsistence strategies, settlement practices, and social and political systems. An understanding of this variability is the key to appreciate fully the Classic Maya.     

POST-COLONIZATION INTERACTION BETWEEN VANUATU AND FIJI RECONSIDERED: THE RE-ANALYSIS OF OBSIDIAN FROM LAKEBA ISLAND, FIJI*

PIXE–PIGME analysis of 19 obsidian artefacts from Lakeba Island in east Fiji identified contact with northern Vanuatu in the post-colonization period ( c. 2500–1000 bp ) of Fiji. The Lakeba obsidian is the only physical evidence for interaction across the 850 km water gap separating the archipelagos of Vanuatu and Fiji in the first millennium ad . New research on the Vanuatu obsidian sources with laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) casts serious doubt on the validity of a long-distance inter-archipelago connection in the post-Lapita era. This paper presents the re-analysis of 18 obsidian artefacts from Lakeba using LA–ICP–MS and radiogenic isotope results that demonstrate that the Lakeba obsidian is not from Vanuatu, and it most likely derives from the Fiji–Tonga region. Geochemical evidence for long-distance interaction and migration between the West and Central Pacific in the post-Lapita era has yet to be identified.     

Evaluating the use of IKONOS satellite imagery in lowland Maya settlement archaeology

This article presents an extensive evaluation, in several contiguous or near-contiguous areas, of the viability of IKONOS satellite imagery in detecting sub-canopy Maya settlement in Peten, Guatemala. Initial research in and around San Bartolo, Guatemala, led to the conclusion that IKONOS imagery could be highly effective in detecting and predicting Maya settlement of the Preclassic and Classic periods, in zones of dense occupation near swampy lowlands known as bajos. The pioneering methods at San Bartolo are applied here to other regions in the Maya lowlands, but with mixed or unpromising results. Preliminary evaluation indicates that local climate, geology, hydrology, topography, pedology, and vegetation differ dramatically in these other regions, with consequences for wider application of the settlement signature discerned at San Bartolo. Possible reasons for these difficulties are offered in this paper, along with ways to strengthen the use of multispectral imagery in archaeological survey of tropical forests.     

Obsidian sources in highland Yemen and their relevance to archaeological research in the Red Sea region

The Red Sea and surrounding area formed through dynamic uplift and rifting of Afro-Arabia, and associated volcanism (both oceanic and continental in character). As a result, volcanic landforms and products are widespread and play a vital role in the natural and cultural landscapes of humans occupying the highlands and lowlands on both sides of the Red Sea. Archaeologists have suggested for some time that Afro-Arabian trade in obsidian had its roots in the prehistoric period and that the region was very likely the source of an abundance of obsidian artefacts found as far afield as Egypt, the Persian Gulf and Mesopotamia, and which do not match the well-known Anatolian, Transcaucasian or Mediterranean sources. Nonetheless, the southern Red Sea is one of the few obsidian-rich regions exploited in antiquity that has been barely investigated. In this paper, we highlight new geochemical analyses (carried out by LA-ICP-MS) of obsidian sources in Southern Arabia and beyond, that enhance our knowledge of obsidian exploitation from as early as the Neolithic period, and which enable us to evaluate the role that highland Yemen obsidian sources played in prehistoric long-distance trade. In addition, we present new evidence for explosive volcanic eruptions that likely affected the highland populations of Yemen in the 4th millennium BC.
