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.     

Beyond cereals: crop processing and Vitis vinifera L. Ethnography,experiment and charred grape remains from Hellenistic Greece

Archaeobotany, ethnographic observation, and laboratory experimentation are brought together to build model sequences of grape processing parallel to the better studied and reported sequences in existence for cereal processing. A set of such model sequences is developed and presented, and explored in the context of rich archaeobotanical assemblages from the Hellenistic farmstead at Komboloi in Southern Macedonia. We conclude that the remains of pressed grapes are reasonably distinctive, whereas whole grapes and raisins can leave similar material in charred state, requiring close scrutiny for secure separation. Our model sequences are further considered in the light of other sites in which Vitis remains have been variously interpreted, and our own reinterpretations offered.     

Quantitative micromorphological analyses of cut marks produced by ancient and modern handaxes

In this study, we analyse the three-dimensional micromorphology of cut marks on fossil mammal remains from a ∼0.5 million year old Acheulean butchery site at Boxgrove (West Sussex, southern England), and make comparisons with cut marks inflicted during the experimental butchery of a roe deer (Capreolus caproelus) using a replica handaxe. Morphological attributes of the cut marks were measured using an Alicona imaging microscope, a novel optical technique that generates three-dimensional virtual reconstructions of surface features. The study shows that high-resolution measurements of cut marks can shed light on aspects of butchery techniques, tool use and the behavioural repertoire of Lower Palaeolithic hominins. Differences between the experimental cut marks and those on the Boxgrove large mammal bones suggest variation in the angle of the cuts and greater forces used in the butchery of the larger (rhinoceros-sized) carcasses at Boxgrove. Tool-edge characteristics may account for some of these differences, but the greater robusticity of the Boxgrove hominins (attributed to Homo heidelbergensis) may be a factor in the greater forces indicated by some of the cut marks on the Boxgrove specimens.     

Remote sensing applications and archaeological research in the Northern Lagoon of Venice: the case of the lost settlement of Constanciacus

“Vicus Constanciacus” is a project for the recovery, protection and evaluation of the historical and archaeological heritage of Constanciacus, an ancient small group of islands in the Northern Lagoon of Venice, of which currently just two emerged strips survive, namely: the abandoned islands of Sant’Ariano and La Cura. Exploring the area lying between the mainland and the lagoon represents an important opportunity for reconstructing the history of Venice before the well known medieval city and market arose. Through survey and excavations of the Constanciacus area, the project aims to shed new light on early patterns of occupation in the Northern Venetian Lagoon; to explore the communication network between the mainland and the sea; and to examine the evolution of settlements along the commercial routes of the Lagoon through time.     

Flights into the past: full-waveform airborne laser scanning data for archaeological investigation

Airborne Light Detection and Ranging (LiDAR) is a quite recent (mid-1990s) remote sensing technique used to measure terrain elevation. Recent studies have examined the possibility of using LiDAR in archaeological investigations to map and characterize earthworks, to capture features that may be indistinguishable on the ground and to aid the planning of archaeological excavation campaigns.     

Discrimination of Ceramic Types Using Digital Image Processing by Means of Morphological Filters

Digital processing of images can be used to analyse ceramic pastes, contributing in this way to the discrimination of ceramic types. The method involves several stages of analysis: digitization of images of ceramic pastes, pre‐processing of the images, particle segmentation, calculation, quantification and classification of the particle sizes. This procedure uses interactive algorithms of segmentation of images and grain size analysis derived from mathematical morphology theory. To prove the efficiency of the method, we processed digital images of polished thin sections of ceramic samples of Cypriot wares from the Late Bronze Age (1550–1450 bc ) and their Egyptian reproductions. Such groups have been previously analysed by optical microscopy, XRD, XRF, ICP–MS and EPMA. The results of the analysis were able to discriminate between these two different wares.     

Early ironworking in Iron Age South India: New evidence for the social organization of production from northern Karnataka

Abstract

Iron production was integral to political and ritual practices during the South Indian Iron Age (ca. 1200–300 b.c.), yet the investigation of the social relations of metals production during this period has been overshadowed by studies of iron consumption, particularly of iron objects in megalithic mortuary contexts. Recent archaeological research in the Tungabhadra River Corridor, Karnataka, has revealed iron production debris within and between settlements in more ephemeral occupational contexts, such as rockshelters. One notable discovery is the earliest ironworking facility in South India at Bukkasagara. The regional pattern suggests that iron production involved at least two classes of specialist producers—smelters and smiths—who exercised varying degrees of control over the practice and products of their craft. It also suggests that iron production was an important component in the construction and negotiation of Iron Age social differences, affiliations, and inequalities.     

Iron IIA slag-tempered pottery in the Negev Highlands,Israel

The article presents results of a petrographic investigation of pottery from Iron IIA settlements in the Negev Highlands in southern Israel. It focuses on a group of almost exclusively handmade wares that are tempered with crushed slag. The polarizing and electron microscopes explicitly identify these inclusions as copper smelting slag. Based on the slag as well as certain rock inclusions, the slag-tempered wares can be sourced to the copper districts in the Wadi Arabah, and hence for the first time provide a link between the Negev Highlands and the Arabah copper production centers in the period under review. More specifically, they demonstrate direct involvement of at least part of the pastoral-nomadic Negev Highlands population in the copper extraction system.     

Regional inequality in China during its rise as a giant exporter: A value chain analysis

China's exports success has implications for regional income inequality, because most of its export products are manufactured in the coastal zone. We propose a value chain-based accounting framework to quantify the contributions of exports to regional income inequality. We employ newly developed interregional input–output tables for China, which distinguish between processing export activities and ordinary export activities. We analyze the period 2002–2012, the decade during which China became the “Factory of the World.” We find that an RMB of processing exports contributed much more to regional inequality than an RMB of ordinary exports or domestic final demand. Still, changes in regional inequality (increasing in 2002–2007 and decreasing between 2007 and 2012) are much more due to rising ordinary exports in the first subperiod and the growth of domestic final demand coupled with changes in the configuration of value chains in the second.
