On the origins of extractive metallurgy: new evidence from Europe

The beginnings of extractive metallurgy in Eurasia are contentious. The first cast copper objects in this region emerge c. 7000 years ago, and their production has been tentatively linked to centres in the Near East. This assumption, however, is not substantiated by evidence for copper smelting in those centres. Here, we present results from recent excavations from Belovode, a Vin?a culture site in Eastern Serbia, which has provided the earliest direct evidence for copper smelting to date. The earliest copper smelting activities there took place c. 7000 years ago, contemporary with the emergence of the first cast copper objects. Through optical, chemical and provenance analyses of copper slag, minerals, ores and artefacts, we demonstrate the presence of an established metallurgical technology during this period, exploiting multiple sources for raw materials. These results extend the known record of copper smelting by more than half a millennium, with substantial implications. Extractive metallurgy occurs at a location far away from the Near East, challenging the traditional model of a single origin of metallurgy and reviving the possibility of multiple, independent inventions.     

Pollen analysis of 15th century cesspits from the palace of the dukes of Burgundy in Bruges (Belgium): evidence for the use of honey from the western Mediterranean

Pollen analysis of two late medieval cesspits from the palace of the dukes of Burgundy in Bruges (Belgium) revealed the presence of pollen from several food plants and their associated weeds. Also a large amount of exotic taxa was found, most of which are not commonly used as food plants. This last group of taxa shows 4 common characteristics: (1) their distribution is restricted to the Mediterranean region, (2) no macrobotanical remains from these taxa have been found (3) they are insect-pollinated and (4) most of these taxa are important elements in pollen assemblages from modern honeys from SW-Spain and S-Portugal. The presence of these pollen types can therefore most probably be attributed to the use of honey originating from this region. The consequences for the palynological analysis and interpretation of pollen assemblages of medieval and post-medieval cesspits and other types of waste deposits are discussed.     

Western technical traditions of pottery making in Tang Dynasty China: chemical evidence from the Liquanfang Kiln site,Xi'an city

This study is based on the SEM-EDS and LA-ICP-AES analyses of a sample of twenty-nine Tang sancai sherds unearthed from the Liquanfang site, Xi'an city. The results indicate that ceramics with yellowish bodies are calcareous and those with red bodies were made of ferruginous clays. The use of calcareous clay in Tang sancai bodies is otherwise unknown in Chinese history, which suggests that the technique of Tang sancai making at this site might have been influenced by ceramic technology from the Near East or Central Asia. The paper therefore argues that the traditional approach of treating calcareous clay as the main characteristic of pottery made in the ancient Near East or Central Asia is not necessarily accurate. It is likely that some calcareous Tang sancai ceramics were made in the capital city of the Tang dynasty.     

Prepared core reduction at the site of Kudu Koppie in northern South Africa: temporal patterns across the Earlier and Middle Stone Age boundary

Kudu Koppie is a stratified late Earlier Stone Age and Middle Stone Age archaeological site located in the northern Limpopo Province of South Africa. The prepared core reduction strategies are described and temporal trends across the ESA–MSA boundary are presented. The prepared cores and endproducts of Kudu Koppie suggest that both the late ESA and MSA toolmakers employed the Levallois Volumetric Concept, but they often exploited a nodule's natural convexities and form. The MSA toolmakers used a greater variety of prepared core methods and more intensively exploited cryptocrystalline and microcrystalline nodules, the scarcity of which may have resulted in a more “formalized” application of the Levallois Volumetric Concept. These observations are considered within the context of human behavioural evolution.     

公共危机治理主体的多元化及结构分析

政府失败理论、治理理论、利益相关者理论和协同理论为公共危机治理主体多元化提供了强有力的理论支撑。在多元主体结构中,政府是公共危机治理的主导力量,也是核心主体;民间组织是公共危机治理的重要力量,也是联系政府与公民的纽带;企业和公民是公共危机治理的基础;媒体是公共危机治理的重要媒介,也是政府与其他主体合作互助信息平台的主要搭建者。

Nodes and edges: A network approach to hierarchisation and state formation in Japan

This paper argues that the centralised hierarchy that emerged at the beginning of the Kofun (mounded tomb) period in Japan can be explained by the locations that the polities to be hierarchised occupy and the differences in the topological potentials that these locations generate. Previous attempts of explaining the phenomenon by attributing its cause to factors such as differential access to resources and control over their distribution have been proven not to fit with the available body of evidence. The application of social network analysis-derived concepts and methods reveals that the topological locations that polities occupied generated different centralities, i.e. different degrees of connectedness to other polities and of mediating interactions between polities, which led to the hierarchisation and centralisation of their relationships. The paper concludes that the topological structure of a social network itself can be a significant cause of its own hierarchisation, and it compares the finding with the manner in which the concepts of agency and power are applied to the explanation of social hierarchisation and centralisation.     

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.     

Modelling spatial heterogeneity and nonstationarity in artifact-rich landscapes

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.     

Determining Olmec maize use through bulk stable carbon isotope analysis

Bulk stable carbon isotope analysis on absorbed organic residues in ceramics can be an effective method for discerning patterns of maize use when the ceramics come from relatively uniform archaeological contexts. The bulk stable carbon isotope method is faster and less costly than the more commonly used compound-specific stable carbon isotope analysis. Moreover, the bulk stable carbon isotope method can determine the presence of C4 plant carbon in samples in which organic compounds have degraded. Bulk stable carbon isotope analysis was used to discern patterns of maize (Zea mays mays) use among a sample of 24 ceramic sherds from an Early Franco Period feasting deposit (ca. cal 650 B.C.) at the Olmec site of San Andrés, La Venta, Tabasco, Mexico. A comparison of the δ 13C results of different categories of ceramics showed that proportionally more maize was used in luxury beverage service wares than in utilitarian vessels, suggesting that maize-based beverages were prominent in this probable elite feasting episode.
