Iron Age animal husbandry in the wetlands of the western Netherlands

During the Iron Age a subsistence economy based on mixed farming existed in the Dutch wetlands. A model based on subsistence is put forward and tested against the archaeozoological data of 27 sites in order to gain insight into the role of animal husbandry. The model confirms that cattle husbandry was the dominant form of animal husbandry but pigs and sheep were also important at some sites. Although a high number of pig bones were expected, their role is mostly insignificant. An explanation is sought in their lack of secondary products and their competition with humans for the scarce cereals in the wetlands. The mortality profiles for cattle are largely in accordance with the subsistence model. Older cattle are used for traction, milk and herd security and sheep were mainly kept for their meat but also for their milk and wool. Differences in animal husbandry between sites also exist. At two sites more cattle were killed for their meat and at three sites the proportion of older cattle was larger than expected. Although this first test renders the subsistence model viable, it needs to be tested against more sites with larger bone samples.     

Early Neolithic diet and animal husbandry: stable isotope evidence from three Linearbandkeramik (LBK) sites in Central Germany

The first appearance of the Neolithic Linearbandkeramik (LBK) in Central Germany occurred during the 6th millennium BC. However, though LBK sites are abundant in the German loess areas, there are only a few studies that reconstruct the diet of these first farmers using biochemical methods. Here we present the largest study undertaken to date on LBK material using stable isotope analysis of carbon and nitrogen to reconstruct human diet and animal husbandry strategies. We analyzed the bone collagen of 97 human individuals and 45 associated animals from the sites of Derenburg, Halberstadt and Karsdorf in the Middle Elbe–Saale region of Central Germany. Mean adult human values are ?19.9 ± 0.4‰ for δ¹³C and 8.7 ± 0.8‰ for δ¹⁵N. The δ¹³C values are typical for terrestrial, temperate European regions, whereas the δ¹⁵N values fall within an expected range for farming societies with a mixed diet consisting of products from domestic animals and plants. The consumption of unfermented dairy products is unlikely as there is direct palaeogenetic evidence of lactose intolerance available for one of the sites. There are no clear indications for dietary differences in sex. Young children under three years of age are enriched in δ¹⁵N due to breastfeeding indicating that weaning likely occurred around the age of three years. The fauna exhibit mean δ¹³C values of ?20.9 ± 0.8‰ and mean δ¹⁵N values of 7.0 ± 0.9‰ respectively. Variation in the δ¹³C and δ¹⁵N in the domestic animals is probably caused by different livestock managements.     

Temporal changes in diet: a stable isotope analysis of late Iron Age and Roman Dorset,Britain

This study investigates the relationship between diet and cultural change in late Iron Age and Romano-British populations from Dorset, England (1st century BC to the early 5th century AD). Dorset was the only region in Britain to exhibit continuity in inhumation burial rites through these periods and a wide array of environmental, archaeological and material culture evidence is available there. A sample of N = 77 human adult and N = 17 faunal rib samples were utilized for carbon and nitrogen stable isotope analysis to test the hypothesis that Romanization of the diet would result in greater dietary variation.     

Diet in the Iron Age cemetery population at Wetwang Slack,East Yorkshire,UK: carbon and nitrogen stable isotope evidence

This paper reports δ¹³C and δ¹⁵N values for human and animal bone collagen from the middle Iron Age site at Wetwang Slack, East Yorkshire, UK. The data indicate a human diet which was high in animal protein, with no evidence for any significant marine food input. No differences were found between high-status vehicle (or ‘chariot’) burials and the rest of the population and no other status differentiations are visible according to burial rite, age or sex groupings, although the data obtained for the older males display an unusual trend. No dietary variation is seen between two site phases and no evidence for an early immigrant group is present. The range of isotope values for the adult human group as a whole is small, indicating that the diet is likely to have been consistent over time and across the population, although two individuals stand out as unusual amongst the 62 analysed.     

The development of animal husbandry from the Late Iron Age to the end of the Roman period: a case study from South-East Britain

In this paper zooarchaeological evidence from Iron Age and Roman sites in South-East Britain is presented and the results are applied to the continuing debate over culture contact and change following the Roman invasion. Evidence from Heybridge in Essex indicates that there were two stages of livestock development. These may reflect the import of new breeding stock into Britain. Differences between the rate of livestock development at this rural site and the nearby urban centre of Colchester indicate differing mechanisms of animal supply between the two sites. The appearance of very large cattle in Late Roman contexts at Boreham in Essex suggests that improvement of animals continued throughout the Roman occupation and was not merely an initial response to new economic and administrative demands. The biometrical evidence from these three sites is compared with evidence from elsewhere in Europe and the development of livestock during the Roman Period is shown to be complex and varied. The impetus and ideology behind the changes in animal husbandry following the Roman invasion in Britain are explored.     

Investigating Dietary Variation With Burial Ritual in Iron Age Hampshire: An Isotopic Comparison of Suddern Farm Cemetery and Danebury Hillfort Pit Burials

The formal Iron Age cemetery at Suddern Farm, located near Danebury hillfort, provides a unique opportunity to investigate whether differences in burial tradition and ritual behaviour seen at the two sites are linked to access to food resources during life. We measured the carbon and nitrogen isotopic ratios of 40 humans from Suddern Farm and compared this information to previously published faunal data from the site and human isotopic data from Danebury. Despite substantial variation in the faunal isotope signatures, the adult humans have notably homogeneous isotopic results, which are very similar to those at Danebury. This indicates that they had similar access to dietary resources, and supports other evidence for the interdependence of sites with regard to their farming practices. Any social practices that define groups within Hampshire Iron Age society at these sites do not seem to have had any detectable influence on diet.     

Considerations for the identification of ritual deposits of animal bones in Iron Age pits

Although ritual practices amongst human groups are well documented, there are often great difficulties in deducing that ritual behaviour was one of the processes leading to the deposition of prehistoric animal bones. This paper examines developments in recent British literature, particularly those related to the interpretation of certain bones found in Iron Age pits and notably at Danebury hillfort. It discusses a set of arguments or criteria on which the growing literature on ritual is based. In most instances the criteria cannot be restricted to a solely ritual interpretation and a wider range of taphonomic explanations are possible. More rigorous excavation records and discussion of evidence are required to identify ritual satisfactorily.     

Stable isotope evidence for palaeodiets in southern Turkmenistan during Historical period and Iron Age

The subsistence patterns of Iron Age and Historical period humans from south-western Turkmenistan have been reconstructed using the carbon and nitrogen isotopic compositions of archaeological faunal and human bones. A qualitative comparison of the isotopic signatures points to a small proportion of ruminant meat and dairy in human diet for both periods. The ranges of proportions of dietary items yielded by a quantitative approach based on concentration dependent mixing models confirm the high proportions of plant food in the average diet, and show little change in the reconstructed diet for both periods. A comparison of results from zooarchaeological and isotopic approaches illustrates their complementarity in subsistence patterns reconstruction.     

Human and animal diet at Conchopata, Peru: stable isotope evidence for maize agriculture and animal management practices during the Middle Horizon

This paper reports δ¹³C and δ¹⁵N values for human and animal skeletal remains from the Middle Horizon (AD 550–1000) site of Conchopata in the Peruvian highlands. The data indicate that maize was the dietary staple for both humans and the majority of animals at this urban site. Camelids at the site segregated into two groups according to δ¹³C values, reflecting two distinct animal management strategies. Human infants were found to have elevated δ¹⁵N values, reflecting the trophic level effect of breastfeeding. No sex based differences in diet were observed.     

Stable isotope investigations of charred barley (Hordeum vulgare) and wheat (Triticum spelta) grains from Danebury Hillfort: implications for palaeodietary reconstructions

Palaeodietary studies typically focus on the analysis of bone collagen due to the limited availability of plant remains. Isotopic analysis of plant remains, however, allow for a more extensive consideration of the contribution of plants to the human diet and can potentially provide information about the environment in which the crops were grown. This paper reports the results of carbon and nitrogen isotope analyses performed on charred barley and wheat grains recovered from pits within Danebury Iron Age hillfort. To the best of our knowledge, this is the first Iron Age site in Britain from which charred grains have been isotopically analysed. Our results suggest that cereals found at the hillfort were grown in several different environmental contexts. The isotope data demonstrate that the herbivores were not consuming a diet primarily based on grains as the δ¹⁵N values of the grains are very similar to those of the herbivores. Palaeodietary investigations typically assume that humans eating plant protein only would have the same δ¹⁵N value as the local herbivores. This assumption is clearly invalid at Danebury, where the humans and animals appear to have consumed either different parts of the same plants or different plants. Researchers typically interpret high differences between human and animal δ¹⁵N values as indicative of diets high in animal protein, however where major plant resources have δ¹⁵N values similar to those of the herbivores our ability to distinguish between plant and animal sources of protein in the diet is limited. Our research has demonstrated that whenever possible it is desirable to measure the isotopic signatures of potential major plant resources in order to understand past subsistence strategies.     

Investigation of palaeodiet in the North Caucasus (South Russia) Bronze Age using stable isotope analysis and AMS dating of human and animal bones

This paper addresses the question of human palaeodietary adaptation in the Eneolithic and Early Bronze Age periods of the North Caucasus (South Russia) using stable isotope analysis. One of the key questions is the presence of fish in the diet. AMS radiocarbon dating of archaeological bone collagen has also been carried out to investigate potential radiocarbon reservoir effects in human skeletal material as a result of an aquatic diet. A fish component has previously been suggested in the diet of Iron Age and Bronze Age humans across Eurasia by isotopic research and radiocarbon dating of contemporaneous human and animal bones. In the North Caucasus however, isotopic data is scant. This study presents a new set of stable isotopic data from several Early Bronze Age sites, mainly belonging to the Maikop culture of the North Caucasus. The results show that the diversity in climate and environment across the northern Caucasus may be a causal factor for the patterns observed in the stable isotope values of terrestrial herbivores. This affects the isotopic values of the humans consuming them. The differences in δ¹⁵N and δ¹³C ranges of both humans and fauna were found to correlate strongly with geography and climate; the most enriched isotopic values are found in the dry steppe areas to the north. Overall, a relatively high enrichment in δ¹⁵N values of humans compared to local terrestrial herbivores and carnivores was observed. This indicates that aquatic resources were probably part of the Bronze Age diet in the region although the extent of this needs further investigation. The dramatic effect of environmental factors on isotopic values in the Early Bronze Age of the North Caucasus illustrates how confident conclusions cannot be drawn on the basis of a small number of samples from widely differing regions and time periods. Radiocarbon dating can provide a useful tool for identifying dietary derived reservoir ages in humans, potentially caused by a fish diet. With two possible exceptions, the nine human–animal bone pair dated as part of this study showed no consistent indication for a consistent reservoir effect.     

Prehistoric animal use on the Great Hungarian Plain: A synthesis of isotope and residue analyses from the Neolithic and Copper Age

The archaeological record of Eastern Hungary indicates that settlement patterns, subsistence strategies, ceramic style, trade patterns and mortuary customs changed from the Late Neolithic to the Copper Age (5000–2700 cal BC). Despite a rich archaeological tradition, questions remain regarding the management and use of domesticated animals and the role animal husbandry played in social change during this transition. Some researchers have hypothesized that these changes reflect a shift towards an economy that intensified its focus on primary and perhaps secondary animal products. Here we synthesize isotope data from human and animal remains and residue analysis from pottery sherds from Neolithic and Copper Age assemblages. Results indicate that the consumption and use of animal protein and fat was relatively high for both periods, with an increase in animal fats in ceramic vessels during the Middle Copper Age; however, milk products do not appear to have played an important dietary role. We conclude that livestock management remained small-scale during the Neolithic and Copper Age and that dairy use was minimal. It is proposed that the cultural changes that occurred at this time were associated with the emergence of smaller, independent farmsteads and perhaps the innovative use of secondary products like manure.     

Iron Age pastoral nomadism and agriculture in the eastern Eurasian steppe: implications from dental palaeopathology and stable carbon and nitrogen isotopes

Iron Age societies of the eastern Eurasian steppe are traditionally viewed as nomadic pastoralists. However, recent archaeological and anthropological research in Kazakhstan has reminded us that pastoralist economies can be highly complex and involve agriculture. This paper explores the nature of the pastoralist economies in two Early Iron Age populations from the burial grounds of Ai-Dai and Aymyrlyg in Southern Siberia. These populations represent two cultural groups of the Scythian World – the Tagar Culture of the Minusinsk Basin and the Uyuk Culture of Tuva. Analysis of dental palaeopathology and carbon and nitrogen stable isotopes suggests that domesticated cereals, particularly millet, and fish formed a major component of the diet of both groups. The findings contribute to the emerging picture of the nuances of Early Iron Age subsistence strategies on the eastern steppe.     

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.     

Fish bone chemistry and ultrastructure: implications for taphonomy and stable isotope analysis

This paper reviews the ultrastructure and chemistry of fish bone, with an emphasis on zooarchaeology and stable isotope analysis. On the basis of the chemical composition of the collagen and the relationships between the collagen and mineral phases, fish bone is more susceptible to biotic and abiotic degradation than mammalian bone and is therefore less likely to be recovered in archaeological deposits. The amino acid composition of fish bone differs from that of mammals, most notably with respect to hydroxyproline content. The C:N ratio of fish collagen is, however, very similar and slightly lower than mammalian collagen, and thus the traditional range of acceptable C:N ratios for archaeological bone collagen (2.9–3.6) should not be shifted or extended for fish on the basis of the amino acid composition of collagen. An extensive survey of published archaeological bone collagen C:N ratios demonstrates that fish collagen from archaeological contexts tends to have significantly higher C:N ratios than mammalian collagen. The elevated C:N ratios in fish bone collagen may be the result of abiotic degradation processes that occur within the bone after death, the presence of exogenous humic contaminants, or endogenous lipid contaminants.     

Alkaline cooking and stable isotope tissue-diet spacing in swine: archaeological implications

In this study we examine the effects of alkaline cooking on carbon and oxygen stable isotopic ratios of mineralized tissues from nine pigs raised on monotonous mixed C3/C4 vegetarian diets. Two sources of collagen (humerus and mandible) and two sources of apatite (humerus and enamel) were analyzed. Within each diet group, humerus and mandible collagens were found to record equivalent δ¹³C and δ¹⁸O ratios; however, enamel apatite was found to be enriched over bone apatite by 2.3‰ in carbon and 1.7‰ in oxygen. Alkaline cooking was found to slightly, but significantly increase the Δ¹³C_{collagen-diet} and Δ¹⁸O_{collagen-diet} of bone collagen. A similar trend towards enrichment was observed in bone and enamel Δ¹³C_apatite-diet and Δ¹⁸O _apatite-diet, but the differences were not significant. Observed isotopic shifts were consistent with increased nutrient utilization of the alkaline-cooked maize as compared to raw maize. In addition, a reexamination of the relationship between diet and tissue carbon isotopic values suggests that species and alimentary type should be considered when interpreting ancient diets.     

Skeletal evidence for health and disease in the Iron Age of northeastern Hungary

As part of a project to examine health trends in northeastern Hungary, 171 individuals originating from two Iron Age sites were examined. The analysis produced data comparable with those previously published from the Bronze Age in the same area. Comparison suggests slight temporal increases in most indicators of morbidity. © 1998 John Wiley & Sons, Ltd.     

Iron smelting and smithing in major urban centers in Israel during the Iron Age

By-products of iron production, mainly slag and bloom fragments, unearthed at three Iron Age urban centres in Israel (Hazor, Tel Beer sheba and Rehov), were analysed in order to better understand the organization of iron production during the Iron Age. The production remains studied are all dated not earlier than the Iron Age IIA, and thus shed light on a period of transition from bronze to iron production. Chemical composition and microstructural analyses enable us to determine that both the smelting of iron ores and the refining of the bloom took place within the urban centres of Hazor and Beer-Sheba. We show that slag cakes are the products of smelting, possibly carried out in pit-furnaces. Hammerscales, products of primary and secondary smithing, were attached to slags. From these observations we infer that all stages of iron production were practiced in these urban centres.     

Iron Age Burial in Wales: Patterns,Practices and Problems

Until the latter part of the twentieth century, Iron Age burial in Britain was thought to be largely archaeologically invisible. However, over the last 40 years the recovery of large assemblages of human remains, often from pits and ditches rather than beneath monumental structures, has changed our understanding of Iron Age funerary practices. The problem, though, is that the majority of this material derives from core areas of study, particularly southern England and Yorkshire. Our knowledge of burial in the more peripheral areas of Britain, such as Wales, is much more poorly understood. The perceived paucity of burials from such regions is often still interpreted as resulting from the practice of archaeologically invisible disposal methods such as excarnation or the scattering of cremated remains. This paper presents a comprehensive review and analysis of Iron Age human remains in Wales. Although the resource for study is relatively small, a variety of practices, disposal methods and treatments of bodies can be recognized which challenge our current narratives. The scarcity of burials when compared to other parts of Britain, such as Wessex, is suggested to be a result of both poor preservation and bias in archaeological research strategies, rather than the dominance of an ‘invisible’ burial rite.
