Palaeolimnological impacts of early prehistoric farming at Lough Dargan,County Sligo,Ireland

This study provides a unique method of inquiry for archaeological investigation with an aim to assess the intensity and effects of Neolithic and Bronze Age farming practices at Lough Dargan, northwest Ireland, through a multi-proxy analysis of a lake sediment core. Chironomid (non-biting midge fly) subfossils and lake sediment geochemistry (δ¹³C, δ¹⁵N and C:N ratios) were used to assess changes in limnological conditions through time. The limnological data were compared with macroscopic charcoal concentration and pollen data to examine the potential influence that early farmers had on a freshwater lake system within a prehistorically active catchment. Results from the chironomid analysis show that the first substantial period of agricultural activity in the early Neolithic (c. 3730–3190 BC) resulted in a temporary shift to more eutrophic lake conditions. There is evidence of animal husbandry with substantial levels of animal waste reaching the lake, leaving an imprint in the geochemical record of increased δ¹⁵N values and decreased δ¹³C values and C:N ratios during this time. The chironomid community reverted back to its pre-impacted state c. 3190 BC in response to a period of reduced farming (c. 3390–3000 BC) which eventually led to a distinct lull in activity, with possible cessation of farming from 3000 to 2700 BC. A return to eutrophic conditions coincided with the gradual return of agriculture, with more permanently altered lake conditions dominating from 2400 BC, even during a 250-year period of reduced human activity commencing at c. 1440 BC. Increased sedimentation rate, along with increases in δ¹³C, δ¹⁵N and C:N, the presence of chironomid taxa indicative of erosion, more eutrophic lake conditions and high concentrations of macroscopic charcoal all point to more intensive land use practices during the Bronze Age. Palaeolimnological data exhibited an immediate response to intensified farming during this time, and were especially responsive to pastoral farming due either to scale of activity or proximity to the lakeside. The success of this study demonstrates the effectiveness of palaeolimnological analysis in the investigation of prehistoric farming. This approach will help inform Neolithic and Bronze Age land-use practice and human–environment relations in the region, and highlights the potential for chironomid-based archaeological research.     

A multi-proxy palaeoenvironmental investigation of the findspot of an Iron Age bog body from Oldcroghan,Co. Offaly,Ireland

In 2003, the remains of an Early Iron Age bog body, known as ‘Oldcroghan Man’, were recovered during the cutting of a drainage ditch in a bog in the Irish Midlands. Only some fingernails and a withe fragment remained undisturbed in situ in the drain face, providing the sole evidence for the original position of the body. A detailed reconstruction of the depositional context of the body has been undertaken through multi-proxy analyses of a peat monolith collected at the findspot. The palynological record shows that the surrounding area was the focus of intensive human activity during the Later Bronze Age, but was largely abandoned during the Bronze Age–Iron transition in the mid-first millennium BC. In the mid-4th century BC, a bog pool developed at the site, evidenced in the stratigraphic, plant macrofossil, testate amoebae and coleopteran records. Plant macrofossil and pollen analysis of peat samples associated with the fingernails suggests that the body was deposited in this pool most likely during the 3rd century BC. The absence of carrion beetle fauna points to complete submergence of the body within the pool. Deposition occurred shortly before or around the time that the surrounding area again became the focus of woodland clearance, as seen in the extended pollen record from the peat monolith. This period corresponds to the Early Iron Age in Ireland, during which renewed cultural connections with Britain and continental Europe can be seen in the archaeological record and widespread forest clearance is recorded in pollen records from across Ireland. The palaeoenvironmental results indicate, therefore, that the demise of Oldcroghan Man took place at a pivotal time of socio-economic and perhaps political change.

Stone circles and the structure of Bronze Age society

Analyses of modern human societies have consistently demonstrated the presence of recurrent grouping levels forming a nested, hierarchical structure. That this structure exists in both hunter-gatherer and western industrialized societies suggests that it may be a fundamental organizing principle of considerable antiquity. Stone circles are perceived as being foci of aggregation for prehistoric groups and thus provide a proxy for the sizes of those aggregations. Combining an empirical analysis of a sample of 140 stone circles with a Monte Carlo simulation model that derives expectations for a continuous size distribution based on the nested hierarchy concept, the current paper suggests that similar organizing principles were already in place during the Bronze Age. Furthermore, it is suggested that findings traditionally attributed to the operation of the ‘rank-size rule’ may in fact reflect the basic underlying structure of human society.     

Household and community behavior at Bronze Age Politiko-Troullia,Cyprus

Abstract

We investigate intrasite patterns of artifacts and floral and faunal data to interpret household and community behavior at the Middle Cypriot (Bronze Age) village of Politiko-Troullia in the foothills of the Troodos Mountains, Cyprus. Floral evidence indicates cultivation of orchard crops (e.g., olive and grape), as well as the persistence of woodlands that provided wood for fuel. Animal management combined herding of domesticated sheep, goat, pig, and cattle with the hunting of Mesopotamian fallow deer. Metallurgical evidence points to the production of utilitarian copper tools in household workshops. Group activities are reflected by the deposition of anthropomorphic figurines, spinning and weaving equipment, and deer bones in an open courtyard setting. In sum, Politiko-Troullia exemplifies a diversified agrarian economy on a distinctly anthropogenic landscape that fostered the development of household and supra-household social differentiation in pre-urban Bronze Age Cyprus.     

Large scale smelting of speiss and arsenical copper at Early Bronze Age Arisman,Iran

We report analyses of different slag types found at the Early Bronze Age site of Arisman in North-West Iran. Here, an estimated 20 tons of slag provide evidence of sustained and large-scale production of metal, using both furnaces and crucibles. The results show that both speiss, an iron-arsenic alloy, and arsenical copper were produced, apparently side-by-side at the same site but using different ores and processes. We offer a tentative outline of the metallurgical processes involved in the production of these arsenic alloys and an explanation why speiss needed to be produced from arsenopyrite in a separate step, instead of using the mineral in its native form as a source for arsenic. We suggest that the speiss was then added either to secondary copper ore or to separately smelted copper metal, in order finally to produce arsenical copper in a regular and well-controlled process.     

Historical context and chronology of Bronze Age land enclosure on Dartmoor,UK

The upland of Dartmoor, southwest England, is one of the flagship prehistoric landscapes within Britain owing to the excellent survival of extensive prehistoric coaxial field systems. Archaeological surveys and rescue excavations during the 1970s and 1980s did much to further the understanding of this landscape; however, much remains to be explored, in particular the chronology of enclosure, the nature of the pre-enclosure landscape and the relationship between Bronze Age communities and their environment. Reconsideration of this landscape is important, given the place it holds in our understanding of subdivision of the landscape across northwest Europe during prehistory. This paper presents new palaeoecological data recovered as part of an integrated archaeological and palaeoecological project on northeast Dartmoor. The sequences detailed here include the first dated Neolithic period palaeoenvironmental data from within the prehistoric enclosed land on the moor, providing a longer-term context for enclosure. Neolithic groups are implicated in the first establishment of heathland in the study area at around 3630–3370 cal BC. During the early Bronze Age, reestablishment of hazel scrub in the study area implies reduced use of the upland, although it is not clear whether this is local or indicative of the wider landscape. A combination of pollen and fungal spore data indicates a substantial shift to species-rich grassland with grazing animals at c.1480 cal BC in a phase that lasted 400 years. The later Bronze Age and early Iron Age are characterised by low intensity use of the upland. These data provide new chronological data for land cover change on Dartmoor and whilst they broadly confirm existing models of upland land use in later prehistory, their proximity to the standing archaeology affords a more nuanced interpretation of local change.     

Ojakly: A Late Bronze Age mobile pastoralist site in the Murghab Region,Turkmenistan

Abstract

Excavations at Ojakly (site 1744) in the Murghab alluvial fan in Turkmenistan mark the first systematic collection of archaeological materials related to Bronze Age mobile pastoralists in the region, and the earliest evidence to date of their occupation patterns, subsistence practices, and ceramic production activities. Because the appearance of mobile pastoral groups in the Murghab during the Late Bronze Age (ca. 1950–1500 b.c.) is traditionally associated with significant changes in regional sociopolitical structures, these data are important for establishing local strategies of and the relationship between sedentary agricultural and mobile pastoral populations. Here, we present ceramic, faunal, archaeobotanical, and lithic data that force us to reconsider the traditional sedentary-mobile dichotomy. Specifically, we find that while the subsistence economies are distinct at urban and non-urban sites, the ceramic production and trade interactions are significantly intertwined and more complex than previously acknowledged for this time period. Additionally, the presence of a ceramic kiln at Ojakly (Turkmen for “place with kiln”) containing unfired ceramics of a type typically associated with sedentary farmers in the Bronze Age Murghab suggests the transfer of technical knowledge between groups who nevertheless maintained distinct material cultural identities. Ojakly provides important new data about coexisting economies in the Late Bronze Age Murghab that can productively unsettle traditional notions of dominance, control, and polarization in sedentary-mobile interactions.     

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.     

The Bronze Age landscape of the Bjäre peninsula,southern Sweden,and its relationship to burial mounds

Palaeoecological analyses from a small fen deposit, combined with pollen analysis from buried soil profiles under prehistoric burial mounds, have been used to investigate the timing and vegetation change associated with the Holocene development of a cultural landscape in southern Sweden. Traditional pollen analysis is complemented with plant macrofossil analysis and soil pollen analysis from within and in close proximity to the burial mounds in the coastal Bjäre peninsula, well known for its high density of well-preserved Bronze Age monuments. The vegetation development is linked to the construction of the burial mounds. A marked increase of cultural impact on the landscape is recorded during the Neolithic–Bronze Age transition and estimates of landscape openness suggest that by the onset of the Bronze Age, forest cover was only 20–40%, falling to 10% in the immediate vicinity of the burial mounds themselves. The coastal strip appears to have been affected by human activity to a greater extent and at an earlier date than sites from further inland in southern Sweden and the Bronze Age burial mounds were most likely designed to be visible in a largely deforested landscape.     

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.     

Sovereignty,mobility, and political cartographies in Late Bronze Age southern Caucasia

This article draws on archaeological data from Late Bronze Age (LBA, ca. 1550–1150 BC) fortress, shrine, cemetery, and residential sites in Armenia to challenge long-held assumptions about the potential for mobile-pastoral groups to develop and sustain complex polities. The past two decades of research by Project ArAGATS (the Armenian–American collaboration for the Archaeology and Geography of Ancient Transcaucasian Societies) has demonstrated that LBA sovereignty emerged not through the sociopolitical coalescence of settled farming villages, but through the actions of hierarchically organized, mobile pastoralists. Post-processual archaeology helped focus discussions of ancient political life on the contingent nature of authority and the processes through which competing factions and stakeholders achieve political association. However, centuries of interpretive marginalization of nomadic peoples combined with deterministic notions regarding subsistence and settlement practices of mobile pastoralists have, until recently, hindered a broader anthropological consideration of the potential pathways to sovereignty available to more mobile societies. Drawing on a range of datasets from LBA fortresses, shrines, cemeteries, and ephemeral residential complexes, our study examines the essential factors contributing to the emergence and maintenance of complex polities among mobile pastoralists in the southern Caucasus, societies that were intimately associated—politically, economically, and ritually—with hill-top fortresses. This study of political association in LBA Armenia sheds light on the internal politics of nomadic communities and offers a unique opportunity to bring the South Caucasus into the comparitive study of ancient complex polities.     

Modelling of hydrology and potential population levels at Bronze Age Jawa,Northern Jordan: a Monte Carlo approach to cope with uncertainty

An annual water balance model for Wadi Rajil, in Northern Jordan, is used to simulate the ancient water supply system for the Early Bronze Age site of Jawa. The model includes: water delivery from the catchment; local pond storage; and water demand for people, animals and irrigation. A Monte Carlo approach is used to incorporate the uncertainty associated with a range of factors including rainfall, evaporation, water losses and use. The stochastic simulation provides estimates of potential population levels sustainable by the water supply system. Historical precipitation estimates from a Global Circulation Model, with uncertainty bounds, are used to reconstruct the climate at Jawa in the Early Bronze Age (EBA). Model results indicate that the population levels in the predicted wetter conditions during parts of the EBA could have risen to ∼6000 and may have been higher in wet years. However, palaeoclimatic proxies also suggest prolonged droughts in the EBA; and during these periods the water management system was unable to provide adequate supply for a population of 6000. The utility of Monte Carlo based hydrological modelling as a tool within archaeological science is discussed.     

Subsistence and the isotopic signature of herding in the Bronze Age Hexi Corridor,NW Gansu,China

Dietary patterns at two Bronze Age sites in the Hexi Corridor are investigated by the analysis of stable carbon and nitrogen isotopes in faunal bone collagen. The findings are compared with archaeobotanical remains from one of the sites which include high proportions of millet (Panicum miliaceum and Setaria italica) as well as the western derived cereals wheat (Triticum aestivum), barley (Hordeum vulgare) and oat (Avena sativa). The isotopic data indicate domestic omnivores (Canis and Sus) had diets dominated by millet. Minimally offset δ¹⁵N values between herbivore and omnivore fauna suggest low consumption of animal protein by omnivores. Diets of herded animal (Bos and Caprinae) included only low proportions of C4 foods, suggesting that these animals were not regularly foddered with millet plants, and that their grazing areas were mostly beyond the agricultural zone. The wide range in δ¹⁵N values amongst herbivore fauna (4.1‰–11.8‰) suggests grazing occurred in a variety of ecological zones, and this would be consistent with the occurrence of long-distance transport of livestock in the region.     

Sediments exposed to high temperatures: reconstructing pyrotechnological processes in Late Bronze and Iron Age Strata at Tel Dor (Israel)

Many of the sediments analysed from Tel Dor (Israel) show structural alterations indicating that they were exposed to high temperatures. This observation is consistent with the abundant evidence for use of pyrotechnology from the earliest exposed Middle Bronze Age strata through the Roman period. Such structurally altered sediments may well represent one of the more widespread and durable records of pyrotechnology, and as such could be invaluable for reconstructing past human activities. The specific aims of this research are therefore to develop the means for identifying local sediments that were altered by different pyrotechnological activities and to elucidate the varying circumstances whereby sediments were exposed to high temperatures in a Late Bronze and Iron Age 1 section.     

Exchange patterns,boundary formation,and sociopolitical change in Late Bronze Age Southern Caucasia: preliminary results from a pottery provenance study in northwestern Armenia

In the South Caucasus—roughly the territory of today's Armenia, Georgia, and Azerbaijan—the transition from the Middle Bronze Age (MBA) to the Late Bronze Age (LBA) is equated with fundamental shifts in settlement patterns, subsistence economy, and political strategies. During the mid-2nd millennium BC, nomadic pastoral societies that had dominated the region began to settle down and construct stone fortresses along the foothills of the Lesser Caucasus; these fortifications largely replaced the expansive and often opulently adorned kurgan burials as the most prominent expression of political dominance on the landscape. After a decade of intensive archaeological study at various fortifications, very little remains known about the political and economic relationships among fortresses on a regional scale that might improve our understanding of the roots of these sociopolitical transformations. In this paper, we highlight the results of a recent neutron activation analysis (NAA) of ceramics from elite and non-elite contexts at a selection of LBA fortresses on the Tsaghkahovit Plain in northwestern Armenia, and offer some preliminary interpretations about political and economic organization and boundary formation. Most strikingly, the NAA data suggest that the fortresses on the Tsaghkahovit Plain appear to have isolated themselves economically from surrounding valleys, perhaps in an attempt to forge boundaries and legitimating ideologies attendant to new political formations that were quite distinct from their nomadic predecessors in the MBA.     

The Terramare and the surrounding hydraulic structures: a geophysical survey of the Santa Rosa site at Poviglio (Bronze Age,northern Italy)

The Terramara Santa Rosa is a Middle and Late Bronze Age archaeological site located in the Po alluvial plain, northern Italy. It is constituted of two moated villages delimited by earthen ramparts. The peripheral structures of the site are sealed by fine-textured flood plain deposits and they have not been fully explored through excavation due to their large extent. Because the shape of the villages and their relation to moats and the fluvial network are of paramount importance to understanding the landscape management and the use of water resources in the Terramare civilisation, a geophysical survey was planned to extend the results of the existing archaeological excavations to the site scale. A frequency-domain electro-magnetic sounding (FDEM) and electrical resistivity imaging (ERI) covered an area of approximately 26 ha; ERI was conducted for a total length >9000 m. Despite the predominance of electrically conductive fine-textured sediments, electrical resistivity anomalies were observed and they were attributed to subtle lithological differences in the sedimentary context of the alluvial plain. The geophysical interpretation, after the calibration with the excavation data, revealed the structures of the Terramara and of the surrounding hydraulic network, which are not visible at the surface due to flood plain deposits. The Santa Rosa site was founded in a favourable geomorphological position, on the top of a crevasse splay lobe of the adjoining Po palaeo-channel, rising above the surrounding alluvial plain. The Terramara and their surroundings were delineated through an artificial modification of this pre-existing crevasse splay lobe and a well-targeted urban design, with the objective of diverting water, most likely from a palaeo-channel of the Po River, through the digging of peripheral moats used to collect water around the site and to distribute it to the surrounding fields for irrigation. The water management documented by this study in the Terramara Santa Rosa can be considered as paradigmatic for the whole Terramare civilisation, which is therefore responsible of the introduction of the irrigated agriculture into western Europe for the first time.
