Dating of 4th millennium BC pile-dwellings on Ljubljansko barje,Slovenia

We present absolute dates of seven late Neolithic pile-dwellings on Ljubljansko barje, Slovenia. They were settled from ca. 3600 to 3332 (±10) and from 3160 to 3071 (±14) cal BC, as shown by investigations of wood using dendrochronology and radiocarbon wiggle-matching. We defined eleven periods of intensive tree felling (and building activities) and one major settlement gap (when no trees were felled) from 3332 to 3160 cal BC. A major settlement gap presumably also followed after 3071 cal BC (i.e., after the end date of the investigated sites). Our investigations included over 2500 pieces of wood, mainly from the piles on which the dwellings were built. Among important wooden artefacts were a wheel with axle (one of the oldest preserved wheels in the world) and two dugout canoes, all from the settlement phase from 3160 to 3100 cal BC. As shown by parallel studies, the economy in the sites was characterized by copper metallurgy, skilful wood processing and use, cultivation of domestic plants, gathering of wild plants, animal husbandry, hunting and fishing. The settlements were contemporaneous with a number of sites in the north of the Alps, the younger ones coincided with the lifetime of the Neolithic Iceman (Ötzi). Since Ljubljansko barje has a strategic position at the crossroads between western central and (south) eastern Europe the presented absolute dates provide a basis for their comparison with other dated contemporaneous sites (in the west), to revise the chronology of similar sites in the (south) east (which are not yet exactly dated), and to evaluate their interconnection and roles in cultural development in prehistory.

最新地球化学研究发现,自然界不同地质条件和成矿环境中的铜同位素组成存在显著差异。根据铜矿中铜同位素变化规律,考古学家已将铜同位素作为一种新的示踪剂应用于考古探源研究之中。文章介绍了铜同位素地球化学的最新发展、考古应用原理、实验方法及相关的考古应用实例。认为尽管自然界铜同位素的变化较为复杂且铜同位素地球化学还处于形成发展阶段,但铜同位素分析法在含铜器物的产地研究中已显示出了较好的应用前景。随着铜同位素地球化学研究的深入及分析技术的进一步提高,铜同位素分析法将会在考古研究中发挥更大的作用。     

Ochre resources from the Middle Stone Age sequence of Diepkloof Rock Shelter,Western Cape,South Africa

Although no paintings are associated with archaeological contexts before the end of the Middle Stone Age, hundreds of ochre pieces were discovered on numerous southern African sites suggesting a lasting tradition of ochre use. The variability and the significance of ochre exploitation remain however poorly documented. The MSA site of Diepkloof Rock Shelter (Western Cape Province, South Africa) offers an ideal opportunity to discuss questions of ochre procurement, processing, and use over a long sequence. This study develops an original methodology based on observations on one hand, and SEM-EDS, XRD and Raman spectrometry analyses on the other hand. By comparing raw materials with our geological database, we show that some iron-rich raw materials were collected more than 20 km from the site. Such long-distance procurement combined with other elements of the overall context suggests a planning of procurement. One main chaîne opératoire based on grinding was identified at Diepkloof. In comparison with other South African sites, we observed no evidence for use as loading agent in adhesives. We conclude that ochre use may follow regional cultural patterns.     

Fortifications and Enclosures in European Prehistory: A Cross-Cultural Perspective

This article reviews recent research into the archaeological interpretation and investigation of fortifications and enclosures during the Neolithic and Bronze Age in Europe. Recent methodological, technological, and cultural developments have expanded our understanding of the temporal, spatial, and formal variability of these features on the landscape. Interpretations of this variability also have varied with different theoretical trends in the discipline. We advocate a cross-cultural approach that focuses on the occurrence of enclosures and fortifications over the long term at the continental scale. Such a macroscalar approach complements interpretive frameworks at the regional and microregional scales. The geographic and temporal distribution of these features indicates that social institutions associated with principles of segmentation and substitutability became formalized and tethered to the landscape during the Neolithic.     

Non-destructive pXRF of mafic stone tools

Archaeological use of non-destructive pXRF has been most systematically applied to the classification and provenancing of volcanic glass (obsidian) artefacts. Comparable work has yet to be developed for non-vitreous artefacts. We report results of pXRF analysis for a sample of grey to black (mafic) aboriginal hatchets from Sydney and adjacent coastal regions to the north and south. The study shows both broad and detailed classification is achievable depending on rock type and degree of elemental depletion or enrichment of the samples. PXRF analysis reveals not only distinct patterns of resource use between the three regions of this study but also enables a high degree of geographic resolution in the case of the basalt artefacts of our sample. We conclude that non-destructive pXRF is effective for reliable characterisation of non-vitreous stone artefacts that have a sufficiently complex and enriched compositional signature (i.e., unaltered basalts); with ∼50% of the basalt hatchets in our sample matched with spatially and geologically specific sources.     

A 6000‐Year‐Old Hand Amputation from Bulgaria—The Oldest Case from South‐East Europe?

A skeleton from Tell Yunatsite in Bulgarian Thrace shows evidence of amputation of the right hand. The individual dates back to the end of the fifth millennium, connecting it to the Late Copper Age of that region. The Chalcolithic settlement on the tell ended immediately after a bellicose assault. Therefore, the question arose if the loss of the hand may be connected with this incidence. Anthropological studies in close collaboration with the archaeologists on site made clear that the abscission took place at an earlier time. This result led to a series of complex questions. These are described in this work. We will show that a congenital origin for the loss of the hand can be excluded, and that the individual survived this severe injury for a certain time span. Several possible explanations for an amputation are discussed. It turns out that a surgical intervention seems to be the most likely reason. It becomes clear that there must have been an excellent medical knowledge in the Copper Age concerning surgery and wound treatment. Furthermore, the survival of the handicapped individual documents a certain social cohesion. Copyright © 2011 John Wiley & Sons, Ltd.     

Trace element discriminants between Egyptian and Mesopotamian Late Bronze Age glasses

The origins of Late Bronze Age glass artefacts found throughout the Mediterranean and Near and Middle East remain controversial. Previous analyses of major and minor elements in both Egyptian and Mesopotamian glasses have proven equivocal, revealing no significant compositional differences between glasses from these two regions. Here we present new Laser ablation-ICPMS analyses of 32 trace elements in 54 samples of both Egyptian and Mesopotamian blue and colourless glasses. Our results show that there are consistent differences between these two suites, which are not related to the colorant and clearly indicate the use of different raw materials and/or manufacturing processes. Compositional variations are related to geological controls, hence this method holds promise for the development of a minimally destructive technique for discriminating between archaeological glasses of different provenance, which will be essential in the interpretation of ancient trade patterns and contacts.     

The Huldremose Iron Age textiles,Denmark: an attempt to define their provenance applying the strontium isotope system

Archaeological textiles recovered on two occasions from the Huldremose bog, Denmark, represent some of the best preserved and complete garments from the Danish Iron Age (500 BC–AD 800). In order to address the question regarding the provenance of the textile's raw material, we applied a recently developed method based on strontium isotopes to wool and plant fibres from these ancient garments. Textile plant fibres from Huldremose I find are of non-local provenance, whereas the wool from which the garment was made stemmed from sheep grazing on glaciomoraine soils developed on Cretaceous–Tertiary carbonate platform sediments widely found in Denmark. The Huldremose II find consists of an unusually large and well preserved garment, which is composed of wool from at least three different provenances. One source is again local, whereas the other two sources, characterized by elevated ⁸⁷Sr/⁸⁶Sr ratios, are compatible with geologically older (Precambrian) terrains which are typical for Northern Scandinavia, e.g. Norway or Sweden. Our study suggests that wool and plant fibres were either traded or brought as raw materials for textiles more commonly and over longer distances than previously assumed.     

The Tripolye culture: Centenary of research

The Tripolye culture of the sixth and fifth millennia B.P., which spread over the territory of what is today Ukraine and Moldova, holds a special place in the prehistoric archaeology of southeastern Europe. This major European culture of the Copper Age existed for about 1500 years and survived as a rudiment of painted pottery cultures until the beginning of the Bronze Age. Its archaeological embodiment is highly diverse, expressive, and distinctive. Forming the eastern fringe of the Balkan-Danube early farming cultures, the Tripofye culture came into close contact with the world of the nomadic steppe herders, and both influenced their culture and was, in turn, influenced by them. This article attempts to synthesize the Tripofye culture archaeology on the occasion of the recent centenary of its investigation.     

The metal compositions of a series of Geistingen-type socketed axes

The bulk metal compositions of twelve socketed axes of the Geistingen type are determined in a fully non-destructive manner by neutron resonance-capture analysis (NRCA). These axes named after a hoard found in Geistingen, a Belgian village along the Dutch-Belgium part of the river Meuse, are considered in the literature to be votive or prestigious objects from the Late Bronze Age. They contain considerable amounts of antimony, arsenic, silver and nickel, adding up to 6–16 wt%. Seven axes have no detectable, or little tin; the other five objects contain 6–12 wt% tin. The compositions of the Geistingen axes are evidence for a further example of the return to the Early Bronze Age practice of smelting fahlore related minerals.     

Strontium isotope analysis and human mobility during the Neolithic and Copper Age: a case study from the Great Hungarian Plain

From the Late Neolithic to the Early Copper Age on the Great Hungarian Plain (4500 BC, calibrated) a transformation in many aspects of life has been inferred from the archaeological record. This transition is characterized by changes in settlements, subsistence, cultural assemblages, mortuary customs, and trade networks. Some researchers suggest that changes in material culture, particularly the replacement of long-occupied tells with smaller, more dispersed hamlets, indicates a shift from sedentary farming villages to a more mobile, agropastoral society that emphasized animal husbandry and perhaps secondary products of domestication. In a previous study (Giblin, 2009), preliminary radiogenic strontium (⁸⁷Sr/⁸⁶Sr) isotope data from human dental enamel showed that Copper Age individuals expressed more variable isotope values than their Neolithic predecessors. These data provided support for the idea that Copper Age inhabitants of the Plain were acquiring resources from a greater geographic area, findings that seemed consistent with a more mobile lifestyle. In this article a larger sample from human and animal skeletal material is used to re-evaluate earlier work and shed new light on the transition from the Neolithic to the Copper Age in eastern Hungary. The expanded sample of strontium isotopes from human dental enamel shows that ⁸⁷Sr/⁸⁶Sr values are more variable during the Copper Age, but the change is more pronounced in the Middle Copper Age than in the Early Copper Age. These results, along with recently published complementary research, indicate that the transition from the Late Neolithic tell cultures of the Plain to the more dispersed Copper Age hamlets was more gradual than previously thought, and that the emergence of an agropastoral economy does not explain changes in settlement and material culture.     

Copper production at Baratti (Populonia,southern Tuscany) in the early Etruscan period (9th–8th centuries BC)

Populonia is commonly regarded as one of the most important iron working centres in Europe in the 1st millennium BC. However, multiple layers of copper slags have been recently discovered at the bottom of the slag deposit occurring along the shoreline of the underlying Baratti Gulf. Copper slag layers have been radiocarbon dated to the 9th–8th centuries BC, i.e. to an early metallurgical stage predating the later large-scale iron production. The overall features of copper slags indicate a single-step smelting process of copper-rich ores containing variable amounts of Zn and Pb. Chemical and textural features of copper slags indicate an optimised, high-efficiency metallurgical process.     

Metallurgical investigations at Godin Tepe,Iran, Part I: the metal finds

Godin Tepe, a large tell situated in western Iran along the Silk Road (High Road) and excavated from 1965 to 1973 by T. Cuyler Young, Jr. (56, 57, 58, 59 and 60), yielded over 200 metal artifacts dating to the Early Bronze through Iron Ages. Sixty-nine of these were investigated for this project using traditional metallography and electron probe microanalysis. It was found that the metal objects at Godin Tepe reflect a range of manufacturing techniques and represent multiple producers. In addition, a high degree of variability in production methods is seen for typologically similar aesthetic items like bracelets and pins, but there is uniformity in production of utilitarian items like chisels. The metals from Godin Tepe have provided great insight into the diverse manufacturing methods present on the Iranian Plateau in antiquity, especially during the Bronze Age.     

Natural preservation mechanisms at play in a Bronze Age wooden shovel found in the copper mines of Alderley Edge

A wooden shovel, dating from the Early Bronze Age, has survived in a remarkable state of preservation in the copper mines of Alderley Edge, Cheshire UK. Other historic timbers recovered from the mines, whilst still intact, have fared less well. An X-ray investigation into the distribution of minerals through the shovel using portable X-ray Fluorescence (PXRF) along with the use of synchrotron-based X-ray Absorption Spectroscopy (XAS) measurements of the copper and arsenic chemical speciations has provided clues to the methods by which metals from the mining environment have entered the wood of the shovel and ensured its survival. The distribution and nature of the minerals so determined suggest that the copper and arsenic, along with a significant lead content, entered the shovel during its original use in working mineral-rich deposits, rather than through the burial environment. The insights gained are expected to be applicable to other wooden artefacts recovered from ancient copper mines in other places.
