Computed tomography study of snuff trays from San Pedro de Atacama (Northern Chile)

Wooden snuff trays from San Pedro de Atacama (SPA) in northern Chile are objects of particular museological value. Computed tomography (CT), a non-destructive analytical technique useful in the analysis of archaeological objects in which physical tampering is not desirable, was used to study provenience of wood, quality of craftmanship, taphonomic processes and nature of gemstone inlays in a group of snuff trays. While wood used in the manufacture of trays was mostly exogenous to SPA, gemstones used in inlays were likely of local origin. These findings support the active exchange of goods proposed for the south-central Andes region. Several features revealed in the trays support the view that craftsmen producing them were skillful artisans.     

Violence in the Atacama Desert during the Tiwanaku period: social tension?

Tiwanaku influence significantly affected the lifestyle of the prehistoric peoples of the Atacama Desert as it represented an important period of social and economic change. Such intense changes as social stratification and new religious and ideological influences have always been characterized as peaceful ones. Palaeopathological studies based on the violence‐induced traumatic lesions of 64 well‐preserved human skeletons from an excavated funerary site named Solcor‐3 have facilitated a comparison between Pre‐Tiwanaku and Tiwanaku periods. Results show an increase in violence between males represented by low‐intensity skull traumas, arrow wounds and a high mortality rate between 20 and 30 years of age during the Tiwanaku period. The interpretation of this data is contrary to the model of peaceful acceptance of the changes that followed the Tiwanaku influence into the Atacama. At least for Solcor‐3, economic and political factors should be re‐considered in order to explain the emergence of social tension during the Tiwanaku period. In the future, more detailed studies will probably help to clarify if conflicts had also extended to other sites in San Pedro de Atacama under Tiwanaku influence.

The origin of the Juch'uypampa Cave mummies: strontium isotope analysis of archaeological human remains from Bolivia

Previous analyses of strontium isotopes from human bone and teeth have identified diverse patterns of residential mobility in the South Central Andes during the Middle Horizon (AD 500–1100). During this time, the large polity of Tiwanaku exerted great influence over what are now southern Peru, northern Chile, northwestern Argentina and Bolivia. Recently, five naturally-mummified individuals were discovered in the cave of Juch'uypampa in the Pulacayo region of southern Bolivia. Although these individuals were buried with a number of fine Tiwanaku-style grave goods as well as non-Tiwanaku items, the burial site is isolated and does not conform to the pattern of large Tiwanaku-affiliated cemeteries and residential sites outside of the Lake Titicaca Basin. Strontium isotope analysis was performed on enamel from two adult men and bone from a third adult male in order to test the hypotheses that one or more of the males was from either the Tiwanaku heartland in the Lake Titicaca Basin, the Chilean oasis of San Pedro de Atacama, which contains a series of cemeteries with Tiwanaku-style grave goods, or the local area in which they were buried. Results show that two individuals likely spent their childhood in the local area where they were interred, while the third man probably spent at least the last twenty years of his life in that region before being buried there. This raises interesting questions regarding the nature of Tiwanaku influence in southern Bolivia and the relationship between the Juch'uypampa mummies and the Tiwanaku polity.     

Nicotine in the hair of mummies from San Pedro de Atacama (Northern Chile)

The consumption of plant-derived hallucinogenic substances through smoking and snuffing is a long-standing tradition in the south-central Andes. Chemical and archaeobotanical evidence point to the consumption of nicotine and tryptamine alkaloids in Northwestern Argentina and of tryptamine alkaloids in San Pedro de Atacama (SPA), in prehispanic times. In this paper, results are reported of gas chromatography–mass spectrometry (GC/MS) analyses aimed at identifying nicotine and tryptamine alkaloids in the hair of mummies from different cultural periods of SPA. Fifty-six samples were examined. While tryptamines were not found in any of the samples, nicotine was found in 35 samples, assigned to the Late Formative (1 of 1 sample from this period), Late Formative or Middle (1 of 2 samples from either of these periods), Middle (4 of 6 samples from this period) and Late Intermediate periods (8 of 12 samples from this period), or without assignment to period due to lack of contextual information (21 of 35 samples unassigned to a period). These results show a continuous consumption of nicotine from the Late Formative to the Late Intermediate periods of SPA (ca. 100 B.C.–1450 A.D.). No associations were found between presence of nicotine in the hair of mummies and presence of snuffing trays or of other snuffing paraphernalia in the corresponding tomb; furthermore, neither the diversity of the funerary context, measured in terms of the number of types of objects, nor the presence of gemstone necklaces differed between tombs with mummies with or without nicotine in their hair. Overall, these results suggest that consumption of nicotine was performed by members of the society at large, irrespective of their social and wealth status.     

Biomechanical insights into activity and long distance trade in the south-central Andes (AD 500–1450)

Long distance trade has been attributed important social and economic roles in the pre-colonial south-central Andes, but how these trade networks were operated and organised, and the roles played by different populations and social groups (e.g. elites), remain uncertain. This study aims to offer new perspective on these questions through biomechanical analyses of human skeletal remains from a probable key site in these networks, San Pedro de Atacama (SPdA). Groups that were more intensively involved in long distance trade are expected to have been more habitually mobile, and thus to show greater robusticity and less circular lower limb bone cross-sections. Lower limb biomechanical properties of elite and non-elite Middle Horizon groups (MH, AD 500–1000) were compared with subsequent transitional MH-Late Intermediate Period (LIP, AD 1000–1450) and LIP groups from SPdA, and with LIP groups from Pica-8 and the Azapa Valley. The results indicate that MH populations from SPdA had less robust lower limbs and were by inference less mobile than their successors, with no differences between elite and non-elite, while robusticity was elevated in the MH-LIP transition group. Alternative explanations for the results, such as changes in herding activities, cannot be entirely discounted based on current evidence, but the results are consistent with hypotheses that SPdA may have served as a hub on long distance trade networks during the MH, before residents became more actively involved in long distance trade following the collapse of key links with the Tiwanaku polity. The results also indicate similar levels of robusticity among LIP populations at SPdA, Pica-8 and in the Azapa Valley, implying they may have been involved in trading activities to a similar extent, and perhaps to a greater extent than SPdA MH groups, as regional intergroup relationships changed.     

Andean Ores,Bronze Artifacts,and Lead Isotopes: Constraints on Metal Sources in Their Geological Context

With a focus on bronze production in the south-central Andes during the Middle Horizon, this study reports the first archaeological use of lead isotope analysis to investigate metallic ores and metal artifacts in the Andean zone of South America. Because the vast majority of metal deposits in the Andean cordillera formed in a convergent plate boundary setting, lead isotope compositions of most Andean ore sources are not unique. Lead isotope ratios of central and south-central Andean ores define four geographically distinct ore lead isotope provinces, oriented and elongated parallel or sub-parallel to the trend of the Andean cordilleras. Consequently, ore lead isotope ratios vary strongly from west to east along transects through the coast, highlands, and altiplano, but they exhibit much less variation from north to south. The strong west-to-east variation in ore lead isotope signatures allows discrimination between ore bodies, and ultimately between metal artifacts, as a function of macro-ecozone location: coast, junga-qiswa, puna, and altiplano. We present the most up-to-date database of ore lead isotope signatures for the south-central Andes including those determined for ores we sampled over an approximate 250,000-km² region within Bolivia, northern Chile, and northwest Argentina. Lead isotope signatures of Cu-As-Ni bronze artifacts from Tiwanaku (altiplano capital) and San Pedro de Atacama (desert oasis entrepôt) establish that altiplano and high sierra ore bodies provided the metal for both assemblages. Conchopata (Wari) arsenic bronze artifacts exhibit lead isotope ratios compatible with the Julcani (Huancavelica) copper sulfarsenide deposit.     

Coastal Maya Obsidian Tool Use and Socio-Economy in the Late Postclassic-Early Spanish Colonial Period at San Pedro,Ambergris Caye,Belize

Microscopic use-wear analysis of the obsidian artifacts recovered from Late Postclassic-Early Spanish Colonial occupations at the site of San Pedro yields useful information for interpreting Maya socio-economic activities. Obsidian traded into the community was used for a variety of tasks with emphasis placed on subsistence and domestic manufacture associated with marine resources, including intermittent and contingent crafting. Trade in obsidian and marine resources likely provided San Pedro community members access to inland economic networks and enabled the acquisition of resources not found on the caye. Microwear on chert and obsidian tools indicates relative stability in the traditional lives of the San Pedro Maya in the 15th–17th centuries a.d. Although the San Pedranos likely suffered to some degree from coastal raiding and the introduction of epidemic diseases by the Spaniards, their off-shore location provided them some protection from the upheaval experienced by the Maya in mainland communities.     

The Use of Strontium Isotope Analysis to Investigate Tiwanaku Migration and Mortuary Ritual in Bolivia and Peru

Strontium isotope analysis is applied in South America for the first time in order to investigate residential mobility and mortuary ritual from ad 500 to 1000. While Tiwanaku‐style artefacts are spread throughout Bolivia, southern Peru and northern Chile during this time, the nature of Tiwanaku influence in the region is much debated. Human skeletal remains from the site of Tiwanaku and the proposed Tiwanaku colony of Chen Chen have been analysed to test the hypothesis that Tiwanaku colonies, populated with inhabitants from Tiwanaku, existed in Peru. Strontium isotope analysis supports this hypothesis by demonstrating that non‐local individuals are present at both sites.     

New and past geochemical data on fresh to brine waters of the Salar de Atacama and Andean Altiplano,northern Chile

The paper deals with the major chemistry and stable isotopes (hydrogen, oxygen, carbon, sulfur, strontium) of waters and solutes from the Salar de Atacama basin (Rio Pedro, Honar Creek and Laguna Chaxa) and Andean Altiplano (Laguna Miñique and Laguna Miscanti). The water inflows of the Salar are chemically quite different, the Rio San Pedro being of Na‐Cl type and the Honar Creek of Na‐HCO₃ type, in keeping with the sedimentary‐evaporitic and volcanic nature of the catchment rocks respectively. The δ³⁴S and δ¹⁸O values of sulfate and the ⁸⁷Sr/⁸⁶Sr ratio of strontium in the streams match those of drained rocks, whereas the δ¹³C values of dissolved carbonate are largely controlled by vegetation. The lagoons are evaporated meteoric water bodies, and the relative air humidity estimated from the slope of the isotopic evaporation line is in accordance with historical data on air humidity in the area. The Laguna Chaxa is Na‐Cl rich, and its isotopic composition are consistent with a mixed sedimentary‐volcanic provenance of sulfur and strontium solutes. The Laguna Miñique is Na‐SO₄ rich, and its sulfate δ³⁴S is nearly identical to that of Laguna Chaxa. The δ¹³C(HCO₃) values are quite different in the Laguna Chaxa and Laguna Miñique, with the former being notably enriched in ¹³C probably because of preferential uptake of ¹²C by the high biological productivity occurring in the lagoon. The limited set of new data is interpreted in the context of a much larger literature database. In particular, previous chemical data on inflows and brines in the Salar de Atacama were revisited, and compared with evaporation path models and mineral stability diagrams (boron, lithium and Mg‐minerals) computed using updated software and thermodynamic databases. The modeling shows that the removal of boron and lithium from sulfate‐rich brines possibly occurs, respectively, as ulexite and sulfate salts, and carnallite should be the final magnesium phase of the brine evolution.     

Identification of psychoactive alkaloids in ancient Andean human hair by gas chromatography/mass spectrometry

Various ethnographic sources have demonstrated the symbolic and ritualistic importance of psychoactive plants in Native American societies. The social milieu of these mind- altering plants appears to be ancient. Archaeological evidence during the Tiwanaku empire expansion along the Atacama Desert of Chile, circa 500–1000 A.D., shows the presence of highly decorated snuffing tablets and tubes as grave goods. The preservation of mummified human bodies in the Azapa Valley, northern Chile, provided an opportunity to test the exact nature of the psychoactive plants used in this region. Using gas chromatography/mass spectrometry (GC–MS), here we show that ancient Andean populations from northern Chile consumed Banisteriopsis, a vine that contains harmine. This is the first direct archaeological evidence of hallucinogenic and medicinal ethnographic practices. Interestingly enough, this rainforest plant does not grow along the Atacama coast, thus our findings suggest extensive plant trade networks in antiquity as far as the Amazon.     

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.     

¿Qué sabemos del Cantar de Fernán González?

The Poem or Book of Fernán González was probably written c. 1250 by a monk of San Pedro de Arlanza (Burgos, Castile) to strengthen the legendary foundation of his monastery by the tenth-century Castilian Count, Fernán González, and to promote his tomb cult there. The Arlanza poet was competing with the benefits that Santiago and San Millán de la Cogolla were trying to get on legendary accounts of the champion of the independence of the County of Castile from the Kingdom of León. It is clear that this is a work of monastic propaganda, designed to attract pilgrims and donations; therefore perhaps a better title for it would be Poem of the Foundation of San Pedro de Arlanza. The Arlanza poet was fond of the popular and orally transmitted Romance epics (Hispanic and Carolingian songs). He knew Siete infantes de Salas, the tradition of the Youthful Deeds of Rodrigo (Gesta de las Mocedades de Rodrigo), the anti-Carolingian song(s) of Bernardo del Carpio, and the Roncesvals Matière. We also suspect that the poet was recasting a now-lost epic cantar de gesta of Fernán González. This cantar was probably also known by Gonzalo de Berceo, who was actively working in San Millán de la Cogolla, a few years earlier, trying to attract pilgrims and donations. In this article, I try to analyze how much we know of the lost Cantar de Fernán González and if the Monastery of Sahagún (León) also reappropriated it for its own propaganda.     

Colouring special needs: Locating whiteness in NIMBY conflicts

In this paper I examine the importance of 'race' and racialization in conflicts over the siting of human service facilities. Little consideration has been given to the way in which racialization shapes community reactions to client groups, and the idea that NIMBY reactions facilitate the reproduction of white privilege. I explore these issues using a case study of community opposition to 'special needs' housing in San Pedro, California. Analysis demonstrates that some facility opponents racialized client groups in an attempt to defend the socio-spatial privileges of whiteness. Opponents also used a romanticized and 'whitened' construction of community to mark 'special needs' clients out of place. However, other community members used European ethnic identities to mark the whiteness of middle-class opponents. The case study provides insight into the racialization of need, and the way in which whiteness is struggled over within specific social contexts. It also contributes to an understanding of how claims to European ethnicity may be used to veil and/or challenge white privilege. Dans cet article, j'examine l'importance de la 'race' dans les conflits reliés à l'emplacement de bâtiments affectés à la distribution de services sociaux. Même si les concepts de race contribuent à determiner les réactions des communautés face aux bénéficiaires de services sociaux, leur rôle à cet égard a été peu étudié, de même que la façon dont ces réactions facilitent le maintien des privileges réservés aux blancs. J'explore ces questions par le biais d'une étude de cas à San Pedro, Californie, où une communauté locale s'est opposée à l'établissement d'une maison de traitement. L'analyse démontre comment certains opposants ont attribué des stéréotypes raciaux aux bénéficiaires afin de défendre des privilèges socio-géographiques blancs. Les opposants ont aussi fait appel à une conception romantique de communauté blanche dans le but de marginaliser les bénéficiaires de services sociaux. Toutefois, d'autres membres de la communauté ont pour leur part invoqué des concepts d'identité ethnique pour souligner les antécédents raciaux blancs des opposants, ceux-ci faisant également partie de la classe moyenne. Cette étude pose un regard utile sur les processus par lesquels des idées de race sont imputés à des concepts de besoin, et sur la façon dont ces idées sont contestées dans certains contextes sociaux. De plus, l'étude met en lumière comments des concepts Européens d'ethnicité peuvent servir à dissimuler et/ou maintenir le privilège racial blanc. En este papel examino la importancia de la 'raza' y racialización en conflictos sobre la ubicación de facilidades de servicio humano. Ha sido muy poco considerado el modo en que la racialización moldea la reacción de una comunidad a los grupos de clientes y la idea de que reacciones NIMBY facilitan la reproducción del privilegio para gente de raza blanca. Yo analizo estos temas haciendo uso de un estudio que trata la resistencia de una comunidad a la provisión de viviendas para personas de 'necesidades especiales' en San Pedro, California. El análisis demuestra que algunos de los adversarios 'racializaron' los grupos de clientes en un intento de defender los privilegios socio-espaciales de la comunidad blanca. Los adversarios también emplearon una romantizada y 'blanqueada' construcción de lo que es comunidad, así marcando los clientes de necesidades especiales fuera de su sitio. Sin embargo, otros miembros de la comunidad utilizaron identidades étnicas europeas para marcar la 'blancura' de adversarios de la clase media. Por este estudio se adquiere una nueva percepción de la racialización de necesidad, y la manera en que se sigue resistiendo el concepto de blancura dentro de contextos sociales específicos. También contribuye a nuestra comprensión de cómo las reclamaciones a raíces étnicas europeas pueden ser aplicados para velar y/o desafiar el privilegio blanco.     

The use of forest resources in central Iberia during the Late Iron Age. Insights from the wood charcoal analysis of Pintia,a Vaccaean oppidum

Charred woods may be used to effectively reconstruct past wood acquisition strategies. We used anthracological data from the pre-Roman settlement of Pintia (Padilla de Duero, Valladolid) to examine the use of forest resources at the local scale. Palaeoecological data revealed heterogeneous landscapes in the inland northern meseta with environments that offered diverse sources of wood for the inhabitants of Pintia, one of the first cities of inland Iberia. Pines (Pinus pinea/pinaster and Pinus sylvestris/nigra) and both evergreen and deciduous Quercus L. and Juniperus L. were the main taxa identified as both fuelwood and construction elements, but the assemblages and frequencies of these taxa differed depending on their use. We also examined the potential of models from human ecology by considering the frequency, handling time and the relative technological value of each taxon to model how people gathered wood resources. The results suggest that although local availability affected the forest resources that were used by the Vaccaei people, specific taxa were positively selected for specific uses.     

Lithium extractivism and water injustices in the Salar de Atacama,Chile: The colonial shadow of green electromobility

This paper analyzes the linkages and feedback between green electromobility, lithium extractivism, and water injustices affecting the Atacameño's indigenous communities in the Salar de Atacama basin (Atacama Salt Flats). Currently, lithium is in high demand in the international markets as a strategic resource for the green electromobility industry, which represents part of the Global North policies established by the Paris Agreement to mitigate climate change's effects. Using both documentary and ethnographic methods based mainly on semi-structured interviews conducted with Atacameño people, public officials, and lithium companies' representatives and workers, we propose a decolonial interpretation of lithium extractivism in brine mining through the lens of Latin American political ecology combined with a decolonial and water justice approach. The results demonstrate how the linkages and feedback between global and local dynamics of lithium mining in the Salar de Atacama constitute a form of green extractivism that further replicates the historical inequalities between the Northern and Southern hemispheres and especially affects the indigenous Andean territories and the water ecosystems in the Global South. We call this phenomenon the colonial shadow of green electromobility. We conclude by exposing the need to rethink global proposals addressing climate change by reducing the commodity demand and aiming for water justice at global and local levels.     

The diffusion of the Cid cult: a survey and a little-known document

Tomb-cults (with which are to be associated family traditions, genealogical matters, and a variety of other aspects) of epic heroes are important for a number of reasons, among these being the fact they may tell us something about the origin and nature of the poems themselves. These questions have been well investigated for France but are still little studied in and for Spain. Both historical and pseudo-historical or legendary traditions are involved, the latter predominating both in quantity and interest. After an introductory discussion, a survey is undertaken of the cult of the Cid, protagonist of the Poema de mio Cid (1207?) and national hero of Spain. The aim is not to give a full account of all aspects, but to cover the less well-known of these in detail and to provide bibliographical indications about aspects that are already adequately explored. Genealogical matters are examined first, then the monasteries, churches and towns in which the cult was present. The ‘little-known document’ is the forged will of a Navarrese prince, which was a key text in the cult at the monastery of Santa Maria la Real de Nájera and at San Pedro de Cardeña.     

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 dendrochronological investigation of stringed instruments from the collection of the Cherubini Conservatory in Florence,Italy

A total of forty-nine stringed instruments of the Conservatory Cherubini collection, at the Musical Instruments Department of the Accademia Gallery in Florence, were submitted to a dendrochronological investigation in order to date them, check the validity of their attribution and to find out more about their construction characteristics. Thirty-seven instruments were successfully dated, thereby determining the terminus post quem date of manufacture. The correlation values of the statistical cross-dating tests were generally very high. The dendrochronological analyses determined which instruments had been made from wood of the same provenance and, in some cases, from the same tree trunk. The mean chronology built from the musical instrument series, named “Accademia Master Chronology”, is 558 years long and dates from 1396 to 1953AD. The interval between the youngest ring dated dendrochronologically and the given date of manufacture increased constantly in the course of the centuries, from a mean value of just over eleven years for instruments built in the eighteenth century, to nearly 74 years in the twentieth century, when the use of old wood from other artefacts became more frequent. Furthermore, in the Cherubini Collection, the average tree rings on violins are smaller than those of other stringed instruments; in fact, they increase in proportion to instrument size and are widest in cello and double bass.     

Incipient urbanism at the Early Andean center of Khonkho Wankane,Bolivia

Abstract

For decades archaeologists have recognized that Khonkho Wankane was an important monumental site in the Bolivian Andes, and most have interpreted it as a Tiwanaku regional center. A decade of research indicates that Khonkho Wankane was an important Late Formative center that engendered Tiwanaku’s Middle Horizon urbanism and ritual-political centrality. It was neither a Tiwanaku regional center nor Tiwanaku’s second city. Furthermore, recent research at Khonkho suggests a critique of the “one center, one polity” model of political complexity. Rather than being the singular center of a spatially bounded multi-community polity, Khonkho was one of multiple interacting Late Formative centers in an emergent macro-community that gave rise to Tiwanaku urban centrality.     

Fishing in the Northern Isles: a Case Study Based on Fish Bone Assemblages from Two Multi-period Sites on Sanday,Orkney

Abstract

We describe six cervid bones — a distal humerus, three distal tibiae, and two astragali — from two Roman sites, São Pedro Fronteira and Torre de Palma, in the Alentejo of Portugal. They are identified on morphological and osteometric grounds as fallow deer, Dama dama. They represent the earliest Holocene evidence for this species in Portugal, and it is suggested that, like the camel, the Romans were responsible for its spread within their Empire. While remains of this animal have not so far been reported in any Moslem period assemblages, there is documentary evidence for the existence of fallow deer in Portugal in the 12th and 13th centuries AD, although the possibility that fallow deer disappeared with the end of Roman rule should be considered.
