A compositional perspective on the origins of the “Nasca cult” at Cahuachi

We provide a compositional perspective on the origins of the Cahuachi cult in Nasca, south coast of Peru. Instrumental Neutron Activation Analysis of ceramics from the Formative site of La Puntilla demonstrate that a small group of pottery known as Nasca 1 blackwares are compositionally consistent with Early Nasca polychromes originating at Cahuachi. These data suggest that the patterns of pilgrimage and group ceremonies exhibited at Cahuachi during Early Nasca began at least in the proto-Nasca phase of Nasca 1 during the Formative. We use these data to further document the Paracas to Nasca transition, a complex and dynamic period in south coastal prehistory.     

Elemental analysis of pottery in the study of its provenance: A review

Elemental analysis of pottery is a valuable scientific approach to investigation of its provenance. Increasing use is being made of the approach, and this paper presents a critical review of the basic methodology and experimental procedures. Genenal problems and limitations of the technique are discussed, and the procedures involved in each of the four main stages of such studies are described. These stages are: (1) selecting specimens of pottery for analysis, (2) obtaining samples from the specimens, (3) analysing the samples, and (4) interpreting the results. For each stage, suggestions are made for generally useful procedures and experimental precautions, and for aspects on which further study seems desirable. Much of the discussion is also relevant to the analysis and typing of artifacts of other materials, e.g., metal and stone objects.     

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.     

Regional integration and the built environment in middle-range societies: Paracas and early Nasca houses and communities

We use the built environment of residential sites (house form and community layout) to investigate the effects of increasing regional integration at the level of the community in middle-range societies. We consider spatial data on house form, arrangement of residences within settlements, site location, and organization of non-residential spaces to reveal specific social phenomena linked with pan-regional political organization and ethnic identity formation, and evaluate how macro-scale processes affect micro-scale phenomena. Specifically, we argue that architecture reflects different community patterns of ritual, integration, and inequality. As a case study, we employ a diachronic perspective for two periods in Peruvian south coastal prehistory to assess the magnitude of changes implied by the genesis of Nasca society out of the preceding Paracas. Survey and excavation data from residential sites in the southern Nasca region indicate that important modifications in local community organization accompanied the regional, wide-ranging effects of Nasca society and its innovative form of regional integration. Comparison of the residential built environment from both periods suggests important changes in ritual and patterns of status acquisition and maintenance. In addition, house form indicates that a greater level of household autonomy accompanied increasing regional integration and a decrease in conflict.     

Investigating the production and distribution of plain ware pottery in the Samoan archipelago with laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

This paper presents a provenance study of 170 ceramic artifacts and 21 ceramic tiles from three islands in the Samoan archipelago using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Our analyses confirm that LA-ICP-MS can be used to differentiate between clay formations on a single island. We identify different distribution patterns for pottery recovered from lowland and highland sites on Tutuila Island. We also examine evidence for movement of pottery between islands, and find only limited evidence for such movement. Our findings suggest dynamic patterns of prehistoric interaction and site use that need to be evaluated with further data from across the archipelago.     

A volcanic inclusions based approach for provenance studies of archaeological ceramics: application to pottery from southern Italy

This work focuses on petro-chemical characterisation of the volcanic inclusions often found within the fabric of many ceramic remains from various archaeological sites in eastern Sicily. Petrographic observations and EMP analyses revealed that volcanic glass is strongly influenced by chemical modifications during the firing process, whereas clinopyroxenes keep their original composition unaltered thus constituting an effective tool for provenance attributions. Multivariate statistical analysis of the latter can in fact unambiguously discriminate between different productive areas by comparisons with pyroxenes from volcanics belonging to distinct magmatic provinces. The method proposed here was tested on ceramic remains of different ages and typologies found in southern Italy.     

Petrographic analysis and INAA geochemistry of prehistoric ceramics from Robinson Pueblo, New Mexico

The examination of thin sections is a successful method for discovering provenance groupings of archaeological ceramics if non-clay inclusions in pottery paste can be identified with petrographically distinctive geologic sources. When this is not the case, geochemical analysis must be employed to search for more subtle evidence of such groupings. This situation is likely to arise in studies, such as the present one, where the objective is to discern local or subregional patterns of pottery manufacture and exchange. Ninety potsherds from site LA46326 in New Mexico were subjected to both INAA and petrographic analysis. The results of this conjoint approach are assessed in relation to geochemical theory and are analysed graphically and statistically.     

Ceramic production,consumption and exchange in the Banda area,Ghana: Insights from compositional analyses

Ceramic production, exchange and consumption in the Banda area, west central Ghana has been affected by historical developments ranging from recent competition with alternative vessels (made of metal and plastic) to political economic upheavals that altered community relationships within and outside the region. In this study, we explore spatial and temporal patterning in pottery production, exchange and consumption using a combination of analytical techniques. Instrumental neutron activation analysis (INAA) of a large sample (491 specimens) of archaeological and ethnographic pottery, clay and temper samples from sites across the Banda area has led to the identification of seven compositional groups whose differential distribution implies shifts in resource selection through the last thousand years. Laser ablation-ICP-MS analysis was used to explore the effects of distinctive tempering agents (crushed slag) on the bulk chemical signature of a subset of Banda ceramics, while petrographic analysis provides insight into the preparation of ceramic fabrics. We integrate insights from these diverse physical studies to investigate the dynamics of pottery production, exchange and consumption over the course of the last millennium in the Banda area and explore potential linkages with broader political economic transformations.     

Earthenware production and distribution in the prehispanic Philippine polity of Tanjay: results from laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

This paper presents the results of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis of low-fired earthenware from the prehispanic trading polity of Tanjay (c. A.D. 500–1600) in the central Philippines. The goal of this project was to determine whether or not the compositional analysis of ceramics could be used to examine the organization of pottery production and exchange relationships in the Bais-Tanjay region of Negros Island. Results indicate that at least five distinct groups of ceramics can be differentiated based on elemental compositions and that pottery production was both a part-time, dispersed endeavor and a full-time, likely centralized, craft. In addition, a number of compositional outliers in the ceramic dataset suggest that interregional trade took place, with pottery made outside the Bais-Tanjay region being imported, especially by upland swidden farmers.     

Dietary shifting in the Nasca Region as inferred from the carbon- and nitrogen-isotope compositions of archaeological hair and bone

The topography of the Andean Region results in short travelling distances among ecologically distinct production zones. As such, it is possible to infer relative changes in residence based on the spatial variability in the isotopic composition of food resources. Here, we determine long-term diet through carbon- and nitrogen-isotope analysis of bone collagen for twenty-nine individuals from Cahuachi, an important ceremonial centre in the Nasca Region. We also reconstruct the temporal sequence of change in dietary isotopic compositions along hair samples for seventeen individuals buried at Cahuachi and the neighbouring site of Huaca del Loro.     

Craft Production, Exchange, and Political Power in the Pre-Incaic Andes

This article explores the relationship between craft production, exchange, and power in the pre-Incaic Andes, with a focus on recent archaeological evidence from Chavín, Nasca, Tiwanaku, Wari, and Moche. I argue that craft production and exchange in concert with materialized ideologies played vital roles in the development of political power in the Andes. In later state societies, craft production, exchange, and materialization were critical in maintaining and legitimizing established political power.     

Provenance research by INAA on ancient Chinese white porcelain excavated from the Maojiawan site of Beijing

More than one million shards of ancient Chinese porcelain were excavated at the Maojiawan pit in Beijing in September 2005. Among these shards, four types of ancient Chinese white porcelain were identified. The ages and provenances of three of these types of porcelain were accurately determined by archaeologists based on typology. However, different archaeologists interpreted the other/fourth type differently. According to the colour of the porcelain body, it was easily identified as the product of the Jingdezhen kilns of the Ming dynasty (1368–1644 AD). However, based on the vessel shape, this fourth type of porcelain was also identified as the product of the Cizhou kilns of the Yuan dynasty (1271–1368 AD). In order to determine the provenance of this type of ancient Chinese white porcelain, 131 shards comprising the four types of white porcelain identified at the site were selected as experimental specimens and analysed by Instrumental Neutron Activation Analysis (INAA). After the processing of experimental data by principal component analysis and geochemical analysis, the results show that the provenance of this type of ancient Chinese white porcelain is the Jingdezhen, not the Cizhou kiln.     

Provenance study of early and middle bronze age pottery from Kaman-Kalehöyük,Turkey, by heavy mineral analysis and geochemical analysis of individual hornblende grains

The provenance of Early Bronze Age and early Middle Bronze Age pottery produced between 2100 and 1970 B.C. and excavated from Kaman-Kalehöyük, Turkey was studied using mineralogical methods, including heavy mineral analysis and geochemical study of individual hornblende grains. The relative abundances of heavy minerals in the fabrics of 20 Early Bronze Age (EBA) and early Middle Bronze Age (MBA) pottery sherds, together with 27 local sediments collected within a radius of 25 km of the site were studied. The heavy mineral distributions in the Kaman region were statistically analyzed for consistencies in their occurrence. Amphibole was found to be the most abundant heavy mineral in most of the analyzed samples, followed by titanite and epidote. The amounts of other minerals such as garnet, clinopyroxene, and zircon are subordinate. Different proportions of heavy minerals in the fabrics allow categorization of the EBA and early MBA potteries into 5 groups. Comparative study of heavy mineral assemblages of local sediments and pottery suggests that half of the EBA and most of the MBA potteries were produced from sediment near the excavation site, whereas the other half of the EBA potteries were produced from sediment occurring at 25 km east or more east of the site. The geochemistry of individual amphibole grains was studied by electron-microprobe analysis. Most of the studied amphibole grains are calcic and aluminous, corresponding to hornblende. They can be further characterized into four types based on their chemical composition. The combination of heavy mineral identity and hornblende geochemistry provides diagnostic evidence for the origins of Kaman-Kalehöyük pottery. These and analogous heavy mineral techniques are effective archaeometric tools for determining pottery provenance.     

Pottery production and distribution in prehistoric Bronze Age Cyprus. An application of pXRF analysis

Portable X-ray Fluorescence (pXRF) analysis of over 400 samples of Early and Middle Bronze Age Cypriot pottery from four widely separated sites identifies both local and non-local products at each. A series of analyses of sub-sets of the data highlights differences in the clays used at each site and for some distinctive types and wares. When assessed in the context of general typological, technological and stylistic factors these variations provide the basis for considering patterns of local production and inter-regional relationships across the island. Although the great majority of pots were locally made, particular wares and shapes were brought in from elsewhere. For some sites finer, more highly decorated vessels are mostly imports, but at others both simpler and more complex vessels were made of the same local clays. While small juglets or flasks may have been containers for transporting small quantities of rare substances, larger vessels are likely to have held less precious material. Open vessels, especially small bowls – some of which are plain, utilitarian items – represent another aspect of social behaviour and inter-regional relationships.     

Differentiation of ceramic chemical element composition and vessel morphology at a pottery production center in Roman Galilee

Cooking pots and bowls from two production locations ca. 200 m from each other at the rural settlement of Kefar Hananya in Roman Galilee were compared employing chemical element composition and vessel-shape analyses. Splits of each pulverized sample, all of which were taken from ceramic wasters, were analyzed by both instrumental neutron activation and high-precision X-ray fluorescence analyses, and computerized vessel-shape analysis was employed for morphological analysis of the same vessel forms from each location. Several statistical techniques (bivariate plots, principal component analysis, cluster analysis and discriminant analysis) were used for analyzing the resultant data. It was found that both the cooking pots and bowls made at each location could be distinguished by employing either chemical composition or morphological analysis. The implications of this work, with regard to investigating both production and consumption sites, and for pottery provenance studies, are discussed. The findings suggest that these analytical techniques can be useful as an aid for chronological differentiations of archaeological pottery.     

Petrographic and geochemical analysis on the provenance of the Middle Bronze and Late Bronze/Early Iron Age ceramics from Didi Gora and Udabno I, Eastern Georgia

We report thin section petrographic and geochemical analysis of a total of 20 Middle Bronze, Late Bronze/Early Iron Age ceramics excavated from Didi Gora and Udabno I located in the Eastern part of the Republic of Georgia and 31 clay samples from eight different regions in the surrounding areas of the sites. The major and trace element compositions of the ceramics and clays were determined using a wavelength dispersive X-ray fluorescence technique. The results indicate that the ceramics were manufactured from local clays in Eastern Georgia, mainly from two local clays without any preference of one of the sources during the Middle Bronze, Late Bronze/Early Iron Age.     

Roman lead mining in Germany: its origin and development through time deduced from lead isotope provenance studies

High precision lead isotope analysis by Multi Collector Inductively Coupled Plasma Mass Spectrometry was applied to the investigation of more than 240 Roman lead objects from several archaeological sites in Germany, in order to obtain information on the pattern of Roman mining activity and ore processing in the area. Measurements of ore samples from German deposits east (Siegerland, Lahn-Dill, Ems) and west of the Rhine (Eifel, Hunsrueck) were made and supplemented with data from literature to create a data bank of lead isotope ratios of European lead occurrences. Comparing the isotope ratios of lead objects with those from German ore deposits shows that the source of over 85% of the objects is Eifel ore deposits, but that, in the early years, the Romans also imported lead from the Southern Massif Central and later from Britain.     

On the provenance and manufacture of red-slipped fine ware from ancient Cassope (NW Greece): evidence by X-ray analytical methods

Energy-dispersive X-ray fluorescence spectroscopy was used to characterize red-slipped pottery (2nd–1st century BC) from ancient Cassope, north-western Greece. The compositional data were statistically treated by principal component analysis and chemical groups were established, representing locally produced and imported items. Mineralogical investigation by X-ray diffraction indicated firing temperatures in the range from 850 to 1000 °C for most of the sherds, while one group consisted of over-fired items, possibly in excess of 1050 °C. The morphology and elemental composition of the ceramic bodies and surface slips were examined through scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy. The analyses revealed that different pottery groups exhibit surface slips of different nature, in terms of thickness, degree of vitrification and elemental composition. Overall, the diversity in technological characteristics of the examined sherds is indicative of the socio-economic conditions prevailing in Cassopaea during the late Hellenistic period.     

Explaining the monopoly in shell-bead production on the Channel Islands: drilling experiments with four lithic raw materials

Significant political and economic developments among the Chumash of southern California were catalyzed in part by the emergence of an intensive, specialist-driven shell-bead industry during the second millennium CE on the Santa Barbara Channel Islands. The production of millions of beads depended in turn on the availability of lithic microdrills of standardized form and materials. Channel Islanders quarried a particular stone type, a blocky Monterey Formation chert, from multiple outcrops situated close to the eastern shores of Santa Cruz Island. Rich archaeological assemblages document the lithic and shell byproducts of these intertwined production systems, each of which endured for several centuries (CE 1150–1819). Islanders invariably chose Island chert for making microdrills: hundreds of thousands of specimens recorded to date are of this material. Furthermore, nearly every microlith in all of Chumash territory (post CE 1150) was produced on the islands; the large populations on the mainland did not participate in microlith making or bead making after CE 1150–1200. We argue that this pattern had its roots not only in the patchiness of key resources and shifting regional social relationships, but also in the physical properties of available raw materials. Here we experimentally assess the properties of Santa Cruz Island chert alongside three important mainland raw materials—Grimes Canyon fused shale, Coso obsidian, and Vandenberg chert—that potentially could have been tapped to make microliths. We test the proposition that Island chert outperforms other lithic materials in drilling efficiency and drill use life. Our experimental results from 108 drilling trials reveal sharp distinctions in performance characteristics across the four materials. We infer that the process by which Islanders became the more-or-less exclusive manufacturers of shell-bead currency in southern California was facilitated by both the efficacy and physical properties of the Island cherts and the propitious locations of the outcrops.
