Tawantinsuyu Integration of the Chillon Valley,Peru: A Case of Inca Geo-Political Mastery

Abstract

Archeological and ethno-historical data from the coastal, transitional, and lower sierra variants of the Chillon Valley, Central Coast of Peru, have led to a new understanding of the nature of Inca political and economic control of one subjugated region. The data reveal that the region was settled unevenly by the Cuzqueños; a more intensive state occupation of the lower sierra is indicated. It is suggested that control of the valley was managed by choice from a geographical-political locus in the highland zone because of certain cultural and environmental circumstances in each valley variant that posed advantages and disadvantages for state operations. Major sites yielding evidence of integration into the Inca state are discussed within the context of such a settlement pattern.     

Deciphering the inorganic chemical record of ancient human activity using ICP-MS: a reconnaissance study of late Classic soil floors at Cancuén,Guatemala

Inorganic chemical analysis of soil floors using inductively coupled plasma-mass spectrometry (ICP-MS) was undertaken to provide information on the nature and location of past human activity in the ancient Maya city of Cancuén, Guatemala. The use of ICP-MS to detect trace and ultra-trace elemental enrichment of two excavated soil floors from the late Classic period is the first study of its kind in Mesoamerican archaeology. Geochemical background of the site was established by the analysis of palaeosols and nearby undisturbed ‘off-site’ soil profiles. Robust statistical methods used in the study clearly distinguished the level of anthropogenic enrichment across the former floors. Many elements measured showed only minor departures (10–20%) from the site's background soil chemistry. The greatest levels of elemental enrichment were detected in the rare earth elements, mercury, and gold. The latter is of particular interest considering the consensus that gold was absent from the world of the Classic-period Maya. Comparisons of the spatial pattern of mercury enrichment with lithic and archaeological data show strong linkages to past industrial and ritual activities. Elevated rare earth element concentrations were recorded broadly across both soil floors and are considered to be related to concentrated human occupation in antiquity.     

Feasting landscapes and political economy at the Early Horizon center of Huambacho, Nepeña Valley, Peru

The present contribution examines feasting practices at Huambacho (800–200 cal. B.C.), an Early Horizon elite center of the Nepeña Valley, Department of Ancash, Peru. Feasts are approached as long-term strategies essential to the political economy of human societies. Drawing upon data from public architecture, material culture and food remains, the study closely considers feasts as political actions and investigates the organization and social meaning of these special events. At Huambacho, I contend that the diacritical aspects of feasting practices, such as the use of exclusive spaces and special paraphernalia, contributed to the dual celebration of communal identity and prosperity, and the creation and reproduction of social inequalities. The research highlights the dual centripetal and centrifugal dynamics of Early Horizon feasts and demonstrates the role of the Huambacho center in advertising the success of the local community based on new forms of production and innovative rules of commensal hospitality.     

Identifying foreigners versus locals in a burial population from Nasca, Peru: an investigation using strontium isotope analysis

During the several thousand years of human occupation in the Nasca drainage on the south coast of Peru, population movement into and out of the region impacted the formation and organization of society, as well as contributed to major cultural transformations. This study identifies foreign versus local individuals through the investigation of burial practices and strontium isotope analysis of human remains from the sites of La Tiza and Pajonal Alto dating from the Early Intermediate Period through the Late Intermediate Period (A.D. 1–1476). Of the ten samples analyzed, two individuals dating to the Middle Horizon were identified as foreigners. One of these individuals was buried in a new elite tomb type providing additional evidence that the Wari state incorporated Nasca into its realm. Two headless individuals, one dating to Middle Nasca with clear evidence of decapitation, and another dating to the Late Intermediate Period who was likely decapitated, were both locals. This suggests the practice of decapitation took place among local groups, and that the practice of decapitation and the use of heads as ritual items or trophies may have continued later in time than previously thought.     

Urban political ecology in late prehistory: New evidence from El Purgatorio,Peru

One of archaeology's greatest strengths is its reliance on interdisciplinary collaboration and the utilization of multiple lines of evidence to inform archaeological interpretation. For example, through an examination of faunal and floral remains, production and storage facilities, and the isotopic analysis of human skeletal remains one can develop a model for urban political ecology in ancient cultures. In this case study, the political ecology of the Casma capital city, El Purgatorio, Peru, is investigated in order to inform our interpretations and conclusions regarding Casma political, economic and social organization. The results indicate that Casma political ecology was firmly based in coastal resources and oriented towards supporting state-sponsored feasting and ritual activities, suggestive of a largely elite-controlled redistributive economy. In contrast to previous models characterizing this time period as one of factionalism and environmental stress, the data suggest that coastal cultural adaptations produced an era of widespread political and economic stability.     

Nari (calcrete) outcrop contribution to ancient agricultural terraces in the Southern Shephelah,Israel: insights from digital terrain analysis and a geoarchaeological field survey

A field survey revealed that Byzantine and Early Arab (ca. 5th to 8th century C.E.) agricultural systems in the semi-arid region of the Shephelah (central Israel) were similar to runoff agricultural systems in the arid region of the Negev (southern Israel). This similarity led to the hypothesis that systems in the Shephelah also function as runoff farms. This hypothesis is not trivial since runoff values in semi-arid regions are generally low due to intensive but short rainfall events, and due to the presence of sink patches that absorb runoff on slope surface. The aim of the current research is to examine whether runoff potential in a representative agricultural system in the Shephelah is sufficient for sustaining runoff farming. A geoarchaeological field survey and digital terrain analysis show that large Nari (calcrete) outcrops on the footslopes generate high runoff values that improve water potential. Hydrological simulations and calculations show that 230 mm of direct rainfall generates a water potential equivalent to 300 mm of direct rainfall. In view of these results, it is reasonable to conclude that the presence of Nari enabled runoff agricultural farming in the Shephelah region, even in drought years.     

The devolution of mudbrick: ethnoarchaeology of abandoned earthen dwellings in the Bolivian Andes

This ethno-geoarchaeological study considers the formation of archaeological deposits through a study of abandoned contemporary mudbrick structures on the Taraco Peninsula, Bolivia. The study site was a domestic compound with rooms for different functions that had been abandoned for over 50 years. Structures were in variable states of decay in terms of roof cover, walling integrity and abandonment fills. Geoarchaeological samples were collected from intact and weathered adobes, earthen hearths, mud plaster, and flooring. Adobes and mud plaster were locally derived from topsoil containing archaeological sediments with added gravel and plant temper. This study found a relatively light anthropogenic signature for decayed earthen houses.Rising damp exfoliated mud plaster despite un-mortared cobble wall foundations. Organic matter from roof fall attracted thriving soil faunal populations, which furthered site destruction through bioturbation, particularly packed earth floors. Sediments derived from weathered mudbrick retained little evidence of prior use as construction materials unless exposed to heat. Sediments exposed to high-temperatures produced the most distinctive rubified features but were structurally compromised. Isolated thermal features from decomposed adobe would not be distinguishable from other hearth types. Adobes exposed to low or moderate heat had few distinctive features in thin section. Intact adobes and floors that were not exposed to heat have fewer pores than natural sediments and distinctive grass inclusions. These adobes disarticulated into loose sediments when exposed to weathering. Adobe fall outside the crumbling structures blended into topsoil.This study sheds light on functional attributes of pre-Columbian construction practices. Thick, fine-textured sterile flooring is commonly encountered in the study region. This would control bioturbation from roof fall in a previous occupation enabling reconstruction in abandoned dwellings. In contrast to the contemporary dwelling, prehistoric mortared cobble foundations would resist rising damp. Cobbles without mortar may relate more to design and construction than durability. These contrasts between contemporary and prehistory construction practices reflect differences in the design, construction costs and functional use-life of adobe structures.     

Identifying locals, migrants, and captives in the Wari Heartland: A bioarchaeological and biogeochemical study of human remains from Conchopata, Peru

The site of Conchopata in the central Peruvian Andes was the secondary center in the heartland of the Wari Empire (AD 600–1000), and in this study we examine whether this urban locale was populated by locals, voluntary migrants from distant regions, and/or captives who were forcibly brought to Conchopata. We examine radiogenic strontium isotope ratios from 72 dental enamel and bone samples representing 31 formal burials and 18 human trophy heads to distinguish between locals and non-locals, and we examine skeletal and archaeological data to establish whether non-local persons were voluntary migrants or captives. We also describe a new, straightforward technique in the evaluation of radiogenic strontium isotope ratios to assist in detecting non-locals when large datasets are available.Results show that natal Conchopata inhabitants should exhibit radiogenic strontium isotope ratios that range from ⁸⁷Sr/⁸⁶Sr = 0.70548 to ⁸⁷Sr/⁸⁶Sr = 0.70610. Thus, among the 31 burials, 29 exhibit local values, suggesting that Conchopata was not a cosmopolitan center to which numerous foreigners migrated; rather, it was populated by local peoples, likely the descendants of the preceding Huarpa culture. The two individuals with non-local radiogenic strontium isotope ratios are an infant and a 17–22 years old female. The archaeological context suggests that the female may have been taken captive for subsequent sacrifice, as she was interred in front of the ritual D-shaped structure in which decapitated human heads (trophy heads) and sacrificed camelids were deposited. Among the 18 trophy heads sampled, 14 have non-local values, confirming previous studies of smaller samples that suggested that Wari warriors travelled to other locales and took captives—both adults and children—for subsequent transformation into trophy heads. Additional analyses of bone-tooth pairs from a subsample (12 burials and six trophy heads) shows that the burial group was much more sedentary (homogenous radiogenic strontium isotope ratios in bones and teeth) and the trophy head individuals were much more mobile (heterogenous radiogenic strontium isotope ratios in bones and teeth). Overall, the multiple lines of evidence support the notion that the Wari Empire occasionally used militaristic means, combined with elaborate ritualism, to subjugate other populations, a tactic that may have helped Wari establish and maintain control in particular regions in the Andes.     

Iron Age Landscapes of the Benue River Valley,Cameroon

The Iron Age settlements of northern Cameroon were dispersed across the landscape, taking advantage of different eco-climatic zones to exploit a variety of natural resources. Situated at the interface of the upper and lower terraces of the Benue River, mound sites in the area around Garoua have occupation histories spanning multiple centuries. The site of Langui-Tchéboua displays evidence for rapid accumulation of sediments approximately 700 years ago, which may have been a deliberate construction strategy that would have allowed the site’s inhabitants to exploit resources in both floodplain and dryland contexts. The combined use of multiple dating methods and micromorphology provide novel insights into both the mechanisms of anthropogenic landscape change and possible motivations governing those choices.     

Radiocarbon Chronometry of Site QJ-280, Quebrada Jaguay,a Terminal Pleistocene to Early Holocene Fishing Site in Southern Peru

Excavations in 1970, 1996, and 1999 at Site QJ-280, Quebrada Jaguay, in southern Peru, yielded enough dateable terrestrial plant material to establish an extensive radiocarbon chronology for the site. QJ-280 is one of oldest well-dated fishing sites in the Americas: it was occupied from the terminal Pleistocene to the mid-Holocene (about 13,000–8,300 calibrated years BP) based on 42 terrestrial radiocarbon dates, encompassing the Jaguay and Machas Phases of the local archaeological sequence. In addition to the terrestrial dates, radiocarbon measurements on valves of two marine surf clam (Mesodesma donacium) individuals from a single, well-dated mid-Holocene Manos Phase archaeological context have provided insight into marine upwelling conditions during the occupation of Quebrada Jaguay. The marine reservoir age varied between 130 and 730 ¹⁴C years during the brief lives of the two clams (up to 5 years each), and varied by up to 530 ¹⁴C years within an individual valve, suggesting strong and variable deep marine upwelling; conditions broadly similar to those that exist in coastal Peru today. These rapid variations in marine radiocarbon age suggest that marine radiocarbon dates from environments with variable upwelling could be skewed by up to hundreds of years.     

Capturing the multiplicities of resilience through popular geopolitics: Aesthetics and homo resilio in Breaking Bad

In this article, Grove and Adey's (2015) call to capture the multiplicities of resilience through aesthetics is advanced by engaging with the first two seasons of the television series Breaking Bad. This engagement demonstrates that the relationality of geopolitics and mobility is important for resilience. To capture dynamics generated by the interplay of geopolitical contexts and resilient subjectivities through popular geopolitics, Jacques Rancière's aesthetics and the concept of the aesthetic subject are deployed. The emergence of homo resilio as a political subject within an imagined American heartland is presented to contextualise the aesthetic reading of Breaking Bad that follows. The character Walter White is presented as a paradigmatic example of homo resilio to map the geopolitics of this subject position. The paper concludes that race and gender feature at the intersections of homo resilio, geopolitics, and cultural criticism, reiterating the importance of popular geopolitics for capturing the multiplicities of resilience.     

Developing a Landscape History as Part of a Survey Strategy: A Critique of Current Settlement System Approaches based on Case Studies from Western New South Wales,Australia

In Australia, geomorphological change since the late nineteenth century ensures surface artifact visibility but the contribution of full coverage regional survey to an understanding of past landscape use is limited by the lack of easily datable artifacts. Here, we describe a multi-stage survey strategy based around intensive archaeological, geomorphological and chronological studies as an alternative to traditional site-based approaches. We view the formation of the archaeological record as a sedimentary process and use a geomorphological approach to understand the history of landscape use from surface artifact scatters. We pay particular attention to recording datasets with reference to the timescales over which they have accumulated, and we discuss the types of behavioral inferences that can be drawn from the results of intensive survey, illustrated using the results from our western New South Wales research.     

The Temple of the Fishermen: Early Ceremonial Architecture at Gramalote,a Residential Settlement of the Second Millennium B.C., North Coast of Peru

The archaeology of the Late Preceramic (3500–1800 b.c.) and Initial Periods (1800–800 b.c.) on the north coast of Peru is focused on monumental ceremonial buildings and little attention has been paid to small residential settlements. Here, I introduce the excavations carried out at Gramalote, a fishing settlement that was interpreted as a specialized producer of seafood with a narrow range of non-subsistence activities. Current data support a broader view of fishing communities during the second millennium b.c. in northern Peru. In this view, the discovery of a ceremonial facility at the Gramalote site opens a discussion about the role of community-level ceremonies and how these local practices are related to those at religious monumental centers of the same period.     

Integrated geoarchaeological methods for the determination of site activity areas: a study of a Viking Age house in Reykjavik,Iceland

For over a decade, geoarchaeological methods such as multi-element analysis and soil micromorphology have been used to identify and interpret activity areas on archaeological sites. However, these techniques, along with others such as magnetic susceptibility, loss on ignition, and microrefuse, artefact and bone distribution analyses are rarely integrated in the study of a single site, even though they provide very different and potentially complementary data. This paper presents a comparative study of a wide range of geoarchaeological methods that were applied to the floors sediments of a Viking Age house at the site of Aðalstræti 16, in central Reykjavík, Iceland, along with more traditional artefact and bone distribution analyses, and a spatial study of floor layer boundaries and features in the building. In this study, the spatial distributions of artefacts and bones could only be understood in the light of the pH distributions, and on their own they provided limited insight into the use of space in the building. Each of the sediment analyses provided unique and valuable information about possible activity areas, with soil micromorphology proving to have the greatest interpretive power on its own. However, the interpretation potential of the geochemical methods was dramatically enhanced if they were integrated into a multi-method dataset.     

Residential mobility and resource use in the Chiribaya polity of southern Peru: strontium isotope analysis of archaeological tooth enamel and bone

The Chiribaya were a complex polity during the Andean Late Intermediate Period (c. AD 1000–1300) in the Ilo and Moquegua Valleys of southern Peru. Recent research has demonstrated that the Chiribaya polity was a señorío, a confederacy of economically specialised parcialidades. Here we test hypotheses regarding the movement of individuals and resources among the Chiribaya‐affiliated sites of Chiribaya Alta, Chiribaya Baja, San Gerónimo and El Yaral, as well as from outside of the Ilo and Moquegua Valleys. Although archaeological human enamel and bone strontium isotope ratios from Chiribaya Baja and San Gerónimo cluster closely, there is a wider variety of strontium isotope ratios observed at Chiribaya Alta and El Yaral. This indicates that individuals buried in cemeteries at these sites had access to a wider variety of resources, and probably moved between different geological zones throughout their lifetimes.

3400 years of agricultural engineering in Mesoamerica: lama-bordos of the Mixteca Alta,Oaxaca, Mexico

The origins of early Mesoamerican agricultural techniques are not well established. Our charcoal-derived radiocarbon chronology dates cross-valley check dams, or lama-bordos, buried by up to 11.5 m of sediment in arroyos near Coixtlahuaca, Oaxaca, Mexico. Now it is clear that people in highland Mexico built lama-bordos at least 3400–3500 years ago, several hundred years earlier than previously dated engineering systems in Mesoamerica. Lama-bordo systems evolved as intensively and extensively managed landscapes coeval with climate shifting to more arid conditions. They provide clear examples of human-produced stratigraphy and artificial landscapes (stair-stepped valleys). More importantly, these lama-bordo systems signal a major cultural tipping point toward sedentary agricultural life and solidify our understanding of the Neolithic transition in Mesoamerica.     

Identification of pastoral sites using stable nitrogen and carbon isotopes from bulk sediment samples: a case study in modern and archaeological pastoral settlements in Kenya

The identification of pastoral sites in the East African archaeological record is problematic. Recently, a method for the identification of degraded livestock enclosure sediments had been developed that takes into account the geoarchaeological indicators of micromorphology, phytolith concentrations and the mineral assemblages. This suite of indicators may not always be present in degraded livestock enclosure sediments. This study presents an additional indicator by which degraded livestock enclosure sediments may be identified, namely the isotopic composition of organic nitrogen measured on bulk sediment samples. We studied a highly controlled ethnoarchaeological sequence of abandoned Maasai livestock enclosure sediments sampled in Rombo area, southern Kenya. The results were compared to archaeological sediments from the Elmenteitan Pastoral Neolithic site of Sugenya, southwestern Kenya, radiocarbon dated to ca. 2000 BP (uncalibrated). The sediments from both sites were studied using all four types of analyses, i.e., micromorphology, mineralogy, phytolith concentrations, and stable carbon and nitrogen isotopic compositions on bulk sediment samples. The results show that in abandoned livestock enclosure sediments of known ages a significant enrichment in the heavy nitrogen isotope (¹⁵N) occurs, and that carbon isotopic compositions may be useful for differentiating cattle from caprine enclosures following their dietary preferences (i.e., grazers vs. browsers). A similar pattern of ¹⁵N enrichment is observed in sediments sampled within the site of Sugenya while sediments sampled outside the site's perimeter are generally depleted in ¹⁵N. The micromorphological, mineralogical and phytolith analyses support the conclusion that the sediments from within the site of Sugenya represent degraded livestock enclosure sediments. The carbon isotopic composition from the degraded dung deposits strongly suggests that livestock kept at Sugenya were cattle. Overall, this study presents new empirical data that can be used for the identification of livestock enclosures, and shows that the isotopic signatures and geoarchaeological indicators can preserve for at least two millennia.     

Assessing the resilience of irrigation agriculture: applying a social-ecological model for understanding the mitigation of salinization

This paper creates and applies a computational model of irrigation agriculture in order to study the effects of salinization in Mesopotamia, with the model developed applicable to cases beyond that studied here. Scholars have long suspected that central and southern Mesopotamia present environments which limited agricultural production over the long-term. In regions such as central Mesopotamia, where salinization likely affected settlement and agriculture in different periods but was more manageable than in more southern regions, fallowing regimes, natural and engineered leaching, and decisions made on when to crop were strategies applied in order to limit the effects of salinization. In this paper, we assess the effectiveness of these coping strategies by incorporating projected climate, soil, and landscape conditions with agricultural practices. The simulation results not only demonstrate the effectiveness and limitations of inhibiting progressive salinization, but they can be compared with the archaeological record in order to determine if the results could reasonably be matched with past events and help to interpret settlement history.     

Three-dimensional (3D) visualisation: the application of terrestrial laser scanning in the investigation of historical Scottish farming townships

Recent developments in digital technologies are heralding significant changes in the way we acquire, visualise and analyse archaeological data. Terrestrial laser scanners can be used to create photo-realistic virtual copies of landscapes, and archaeological features, and offer the potential to improve our understanding of three-dimensional (3D) spatial relationships at study sites. Here we present a methodology for the integration of a high-resolution 3D site model with soil chemical data obtained from an abandoned settlement site located in the Central Highlands of Scotland. At this site, the multi-element concentration in soil, co-visualised within a topographic setting, has an important role to play in elucidating settlement layout and activity. The methods described here are also of significance in archiving sites of archaeological/historical importance where development activities and/or environmental processes may destroy remains, or where access to field sites is restricted.
