Strict solar alignment of Bronze Age rock carvings in SE Sweden? – Critical remarks on an archaeoastronomical case study

A recently published paper proposing a “strict solar alignment” of figurative rock carvings in southern Sweden requires some critical and cautionary remarks. Using the paper “Strict solar alignment of Bronze Age rock carvings in SE Sweden” by N.-A. Mörner as a case study, various pitfalls and challenges in archaeoastronomical investigations are highlighted. Substantiating the idea of a relationship between the orientation of archaeological features such as rock carvings and astronomical events such as sunrise at winter solstice requires accurate and precise determination of (i) the orientation of the archaeological features and (ii) the azimuth of the astronomical event at the time of creation of the rock carvings, taking into account all influencing factors such as changes in Earth orbit parameters, surrounding topography and vegetation. Furthermore, possible motivations or intentions of Bronze Age rock carvers have to be considered. When trying to support a causal link between the orientation of archaeological features and astronomical events, it is indispensable to discuss and exclude possible alternative explanations, related to, for example, rock carving practice and visibility. Taking into account the above issues, there is no evidence for a solar alignment of the Järrestad rock carvings. The issues discussed using the Järrestad rock carvings as a case study are relevant to archaeoastronomical investigations in general.     

Tropical behavior of mesospheric ozone as observed by SMM

The seasonal behavior of low latitude mesospheric ozone, as observed by the SMM satellite solar occultation experiment, is detailed for the 1985–1989 period. Annual as well as semi-annual waves are observed in the 50–70 km altitude region. In the latitude range of ±30 the ozone phase and amplitude are functions of temperature and seasonal changes in solar flux. Temperature is the controlling factor for the equatorial region and seasonal changes in solar flux become more dominant at latitudes outside the equatorial zone (greater than ±15). There is a hemispheric asymmetry in the ozone annual wave in the 20 30 region, with northern hemispheric ozone having a larger amplitude than southern hemispheric ozone. In this region temperature is nearly in phase with ozone in both hemispheres and is reduced in amplitude in the northern hemisphere. The equatorial region is characterized by a strong semi-annual wave in addition to the annual variation, and temperature is nearly out of phase with ozone. At all latitudes there is a larger ozone concentration at sunrise than at sunset. The sunrise sunset difference increases with increasing altitude     

Topside and intelhemispheric ion flows in the mid-latitude plasmasphere

A modelling study has been carried out of field-aligned ion flows in the topside ionospheres of conjugate hemispheres under solstice conditions at mid to low latitudes. In the model calculations coupled time-dependent O⁺, H⁺ and electron continuity, momentum and heat balance equations are solved along dipole magnetic field lines at L = 1.5 and 3.0 Sunspot medium and sunspot minimum atmospheric conditions are considered.It has been found that thermal coupling between conjugate hemispheres gives rise to strong flows of O⁺ in the topside ionosphere of the summer hemisphere that are directed upwards at conjugate sunrise and directed downwards at conjugate sunset. At conjugate sunrise in the winter hemisphere there is a small upward-directed signature in the O⁺ field-aligned flux; there is no observable signature in the O⁺ field-aligned flux in the winter hemisphere at conjugate sunset. There are strong upward and downward flows of O⁺ at local sunrise and local sunset, respectively, in both the summer and winter hemispheres.At both L = 1.5 and 3.0 the 24 h time-integrated interhemispheric H⁺ flux is in the direction summer hemisphere to winter hemisphere. At L = 1.5 its magnitude is in good agreement with the magnitude of the 24 h time-integrated plasma (O⁺ + H⁺) field-aligned flux at 1000 km altitude; there are no such agreements at L = 3.0.A study of the roles played by the individual terms of the O⁺ momentum equation has demonstrated the complex structure of momentum balance. Certain of the terms may be orders of magnitude greater than the combined total of the individual terms, i.e. the O⁺ field-aligned flux.     

Changing growing conditions for crops during the Near Eastern Bronze Age (3000–1200 BC): the stable carbon isotope evidence

The analysis of carbon isotope discrimination (Δ¹³C) in crop plant remains from seven Bronze Age sites in northern Mesopotamia and the Levant shows clear differences in water availability between the different geographic areas and throughout the different periods (3000–1200 BC). Amongst the different moisture variables modelled precipitation minus evaporation (P-E—using a macrophysical climate model (MCM)) results in very high correlation (0.74) with Δ¹³C values in barley, supporting the significance of climate parameters (effective moisture) in carbon fixation in this species. The comparison of Δ¹³C values of different crops in different periods confirms increased aridity during the Middle Bronze Age (2000–1600 BC), compared to the later Early Bronze Age (2700–2000 BC) particularly in the north-eastern Syrian territory with generally lower Δ¹³C values during the Middle Bronze Age, as has been documented in palaeoclimate proxies, and in agreement with the MCM. Standard deviation in Δ¹³C values from grains or seeds of one species originating from different samples of an individual site may be understood as variability in moisture conditions during the grain-filling period around the considered location. Large standard deviations occur preferably in sites with low mean annual precipitation (e.g. at Emar) and suggest that in these sites, at least some of the crops were irrigated.     

Dietary Variability During Bronze Age in Central Italy: First Results

This research aims at delineating the dietary practices in Central Italy during the Bronze Age. The study of food choices is a mean for investigating palaeoenvironmental agricultural and economic activities and social relationships, which have been little explored until now in Italy from this specific perspective. Recent researches have showed that the Middle Bronze Age is a crucial period of dietary changes in Italy. Following these first observations, we studied three Bronze Age sites in Tuscany and Latium: Grotta dello Scoglietto, Grotta Misa and Felcetone. Analyses of stable carbon, nitrogen and sulphur isotopes on 38 human and 22 animal collagen samples were performed. The results show three different dietary patterns. Data from Grotta dello Scoglietto (Early Bronze Age) indicate a high‐protein intake, with a probable consumption of fish. Additionally, sulphur results let us infer the presence of some non‐local people. Individuals from Felcetone (Initial phase of the Middle Bronze Age) show a terrestrial diet dominated by plant proteins, which suggests a low δ¹⁵N food intake, namely legumes, as well as C₄ plant, such as millet. Finally, values from Grotta Misa (Middle Bronze Age) highlight a mixed terrestrial diet and the consumption of millet. Given the variety of the obtained results, we are able to conclude that the transition from the Early to the Middle Bronze Age represents a moment of change, which is reflected by the presence of different dietary patterns.

When the Giant Falls: Endurance and Adaptation at Çadır Höyük in the Context of the Hittite Empire and Its Collapse

At the end of the Late Bronze Age, around 1200 b.c., the Hittite Empire of Anatolia collapsed. While that collapse has been well studied, the effects on Hittite-held lands are less so, with many archaeologists positing an abandonment in Hittite territories for a period of time early in the Iron Age. Recent excavations at Çad?r Höyük, 70 kilometers from the Hittite capital, have revealed both typical Hittite material culture belonging to the Late Bronze Age, including mass-produced ceramics and massive fortifications, as well as evidence suggesting that the site’s residents faced challenges, and adapted accordingly, in the wake of Hittite withdrawal and collapse, during the Early Iron Age. The architecture, ceramics, and zooarchaeological evidence from this rural settlement suggest ways in which residential continuity, cultural resilience, and technological and economic adjustments allowed inhabitants to survive and rebound in the face of political instability.     

Adult fracture patterns in prehistoric Thailand: a biocultural interpretation

The prevalence and distribution patterns of trauma in samples of human skeletal remains can reflect the risks to which the community was exposed in daily activities or as a result of interpersonal violence. This paper describes the patterns of non‐vertebral fractures in skeletal samples from four prehistoric Thai sites in terms of long bone fracture rates and individual prevalence rates. The sites range in date from c. 2000 BC (Neolithic) to 400 BC (late Bronze Age), and in environment from coastal estuarine to seasonally dry upland plains. These differences in the natural and cultural environment provided a basis for comparison among the samples representing nearly 300 adult individuals. The types of fractures ranged from simple to severe, but most had healed successfully with few limiting complications. The small bones of the hands and feet as well as clavicle and forearm bones were most frequently fractured among all samples. Overall there was an increase in the major long bone fracture rates from the Neolithic (0.3%) to the Bronze Age (3.0%) that may reflect a change in subsistence activities such as land clearance for the intensification of rice agriculture. The prevalence of ulnar fractures is particularly high in the Bronze Age, and the analysis of their possible cause, combined with evidence for craniofacial fractures, is suggestive of the presence of interpersonal violence in a small number of individuals.

Original DocumentsCharter of Cuthwulf,Bishop of Hereford

The investigation of a Late Bronze Age occupation layer on the banks of the Thames below Wallingford, on a number of occasions since 1949, has yielded an assemblage of Late Bronze Age pottery, flints, small finds including metalwork, and animal bones. The environment of the site, and the sequence of alluviation, have been elucidated by molluscan analysis.

The precise character of the settlement is unknown, but it can be compared with other British later Bronze Age settlements in respect of both its riverside location and the presence of a ‘midden’ deposit. The site bears directly on the question of riverine finds of Bronze Age metalwork; it is concluded that settlement erosion does not account for much of this material. The site is one of the few Late Bronze Age settlements to have been indentified in the Upper Thames Valley, and represents an early phase in the Iron Age settlement sequence of this area.     

Environmental Archaeology of Prehistoric NW Crete

Abstract

The occurrence of Central European tree-types no longer growing on Crete indicates that Neolithic and Bronze Age climates were moister than at present. Of equal significance is the appearance of large quantities of olive pollen in Late Neolithic levels, suggesting the practice of olive cultivation. Early Bronze Age levels show a disappearance of some Central European tree pollen and an increase in Mediterranean tree types, suggesting that the climate became somewhat drier. The pollen findings are used along with other environmental and archaeological data to reconstruct landscapes for the Neolithic and Bronze Age of NW Crete.     

Mobility in Central European Late Eneolithic and Early Bronze Age: tibial cross-sectional geometry

An absence of settlement features during the Central European Corded Ware period (Late Eneolithic, 2900–2300 BC) has been interpreted as a reflection of mobile pastoral subsistence. Recent analyses of the Late Eneolithic archeological context reveal that the Late Eneolithic exhibit evidence of sedentary agricultural activities similar to the Early Bronze Age. Since the archeological analyses are not clear cut, we tested mobility pattern differences between the Late Eneolithic and Early Bronze Age using biomechanical analysis of the tibial midshaft cross-sections. The total sample of the 130 tibiae representing five archaeological cultures was used. The results of the tibial midshaft geometry do not support the hypothesis about different mobility in the Late Eneolithic and Early Bronze Age. This conclusion is supported by nonsignificant differences between the Corded Ware females and the Early Bronze Age females. Higher absolute values for the Corded Ware males should be explained either by stochastic variation or by differing amounts of physical demands despite a generally similar pattern of subsistence of the Late Eneolithic and Early Bronze Age. One of the Early Bronze Age samples, the Wieselburger group, is an exception because the individuals show both reduced overall size and bending resistance of the tibial parameters not only in comparison with the Late Eneolithic but also to the rest of the Early Bronze Age. The results suggest that the behavioral processes which affected the tibial midshaft biology operated during the Late Eneolithic and Early Bronze Age as a mosaic across time and between/within cultures.     

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.     

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.     

Archaeobotanical inference of Bronze Age land use and land cover in the eastern Mediterranean

Charcoal and charred seeds at five Bronze Age archaeological sites discern ancient land use in the eastern Mediterranean. Seed frequencies of orchard crops, annual cereals and pulses, and wild or weedy plants are used to characterize plant utilization at different archaeological sites on the island of Cyprus, in the Rift Valley of Jordan, and in the Jabbul Plain and along the upper Euphrates River valley in Syria. Seed to charcoal ratios provide proxies to determine the relative usage of dung versus wood for fuel across the ancient Mediterranean landscape. Greater charcoal and lower charred seed values are interpreted to represent a wooded environment, while higher amounts of charred seeds and minimal wood charcoal suggest a much great use of dung as a fuel source. Interestingly, Politiko-Troullia (Cyprus, Cypriot archaeological sites are, by convention, named for the nearest modern village (Politiko), followed by an italicized toponym (Troullia) referring to the plot of land that incorporates the site) has the lowest seed to charcoal ratio, suggesting its residents primarily burned wood and that the landscape surrounding Troullia remained relatively wooded during the Bronze Age. In contrast, villagers at Tell el-Hayyat (Jordan) utilized a mixture of wood and dung, in contrast to Tell Abu en-Ni’aj (Jordan), and especially Umm el-Marra and Tell es-Sweyhat (Syria), where inhabitants relied solely on dung fuel. Comparative analysis and interpretation of seed and charcoal evidence thus illustrates the variety of fuel use strategies necessitated by the dynamic and diverse Bronze Age landscapes of the Eastern Mediterranean.     

‘The Chicken or the Egg?’ Interregional Contacts Viewed Through a Technological Lens at Late Bronze Age Tiryns,Greece

This paper reviews the environmental circumstances of the ostrich and its eggs, in order to provide a geographical overview of past human usage and modification of ostrich eggshells in the Aegean and, more specifically, at Tiryns, while placing this craft in its contemporary context in the Late Bronze Age Mediterranean basin. This ostrich shell evidence from Tiryns is contextualized and analysed through the approach of the chaîne opératoire in order to understand the material in the framework of Tiryns' Late Bronze Age craft activities, and within the Late Bronze Age Aegean network of contacts that brought this material to Tiryns in the first place.     

Response to late Bronze Age climate change of farming communities in north east Scotland

Pollen analyses are presented spanning the Bronze and Iron Ages at two sites within one river catchment in north east Scotland, one upland and one lowland site, to test the hypothesis that subsistence agricultural communities relocated their activities in response to major climatic deterioration at the end of the Bronze Age. Such responses were identified, involving the probable cessation of arable farming around the upland site and increases in the intensity of anthropogenic impacts around the lowland site. These changes are consistent with a model that posits a restructuring of agricultural activities, but are not considered indicative of settlement abandonment in the face of climatic stress.     

News and Short Contributions

Abstract

Temporal and spatial patterns of faunal, floral, and ceramic deposition reveal several aspects of household and village economy at Tell el-Hayyat, Jordan. Hayyat was a modest farming hamlet (0.5 ha) with 100–150 inhabitants, which was occupied in six major phases between ca. 2100 and 1500 B.C. This timespan covers the entire Middle Bronze Age, commonly considered the heyday of early urbanism in the southern Levant. Ethnographic and ancient historical exa1nples of agrarian villages in SW Asia include settlements administered by crown or temple estates, held as private property by elite families or absentee landlords, or owned collectively by resident villagers. Data drawn from Tell el-Hayyat Phases 5,4, and 3 (dating to Middle Bronze IIA and IIB) suggest some changes toward a commercially-oriented rural economy, as might be anticipated for villages held by institutional or private estates. Most of the Hayyat data, however, suggest trends toward enhanced economic autonomy, as expected for a collectively owned community. Tell el-Hayyat exemplifies the economic resilience of Levantine villages in the face of developing Middle Bronze Age town and city life.     

Paleoclimate,Geology, Geomorphology,and Middle Holocene Settlement Systems in the Delice Valley of North-Central Anatolia

The Delice Valley in north-central Anatolia is one of the regions where Hatti societies lived during the Early Bronze Age. This region has rarely been explored in terms of its geology, geomorphology, and human-environment interactions throughout the Bronze Age. The focus of the Delice Valley Survey is to build a holistic approach to assess complex socio-ecological dynamics in the region from the perspective of the longue durée. This paper examines the paleoclimatic conditions, the settlement systems, the production capacity of agropastoral systems, and the changes in the political economy in the Delice Valley during the Early Bronze Age and the Iron Age. The results of the first season of fieldwork suggest that the Delice Valley was settled intensively only during certain periods. Although paleoclimatically suitable for denser settlement, the area showed significantly lighter settlement patterns during the Middle and Late Bronze ages.     

On the Book of Devotions,Deposited by Cardinal Howard in the Library of the Dominican Convent at Bornheim in 1659

This paper reports the results of the excavation of an Early Bronze Age cist cemetery on the mid-Northumberland coast at Howick. The Bronze Age site was discovered during the investigation of a Mesolithic hut site, the latter having been published separately as a monograph. A total of five cists were found with only one being adult-sized, the rest presumably for infants. Due to the acidic conditions on the site, only a few fragments of a small skull were found in Cist 2. Other small finds included a small sherd of Food Vessel urn in an area of disturbance next to Cist 5, smoothed limestone cobbles and some nodules of yellow ochre. Flints were found in most of the feature fills, but these are considered to be residual as they are directly comparable to the narrow blade material found within the Mesolithic hut and its environs. The siting of Early Bronze Age cist burials in coastal locations is thought to reflect contemporary settlement on the coastal margin and its hinterland. With no Bronze Age dwelling sites known from this area, these cemeteries have an added significance as they provide indirect evidence for Bronze Age settlement on the North-East coastal plain.     

Metalworking and Recycling in Late Bronze Age Cyprus – the Evidence from Kition

Excavations at the sacred precinct of the Late Bronze Age city of Kition uncovered the remains of metalworking workshops which were clearly associated with the temples. The results of the excavation as well as a number of specialist reports of the archaeometallurgical finds have already been published. Since their publication, however, archaeological research has progressed and new evidence has come to light regarding the Late Bronze Age in general and metalworking in particular. The object of this paper is to present the finds from these workshops and reconsider some of the issues that their discovery has raised. The results of the previous studies of the archaeometallurgical studies are critically assessed and the evidence reinterpreted based on what is available today. One of the issues addressed is that of metal recycling during the Late Bronze Age. This communication was presented at a research workshop organized by the Israel Science Foundation and the University of Haifa on 'Recycling, Hoarding and Trade in Bronze, 13th–11th centuries BCE' (Haifa 26–28 April, 1998). The first part of the paper was written by Karageorghis, the second part by Kassianidou.
