Elevated lead exposure in Roman occupants of Londinium: New evidence from the archaeological record

The evolution of metallurgical practices over several millennia has resulted in human exposures to a diverse variety of toxic elements. These exposures were not just confined to the metalworkers, but in many cases broadly impacted the larger community and society. The role of lead in Roman civilization is particularly fascinating, where the available evidence of lead use in a myriad of applications by Roman civilization suggests the potential for elevated exposures. The present paper addresses the hypothesis that because of these practices, Roman occupants of ancient Londinium (43–410 ad ) were exposed to levels of lead that far exceeded exposures in the preceding populations of Iron Age Britain (700 bc –43 ad ). The elemental content and stable lead and strontium isotopic signatures of 30 femora from three Londinium cemeteries and radiocarbon-dated representative burials were examined and the results then compared with 70 femora dating to the pre-Roman Iron Age from the well-known Iron Age hillfort of Danebury, Hampshire, and from three cemeteries in East Yorkshire. Extensive efforts were directed at the minimization of sediment and soil contamination, the assessment of contamination from burial artefacts and a careful review of the burial context of specimens. Data for lead and 20 additional trace and major elements were obtained by magnetic sector inductively coupled plasma mass spectrometry (ICPMS), after acid dissolution of pre-cleaned bone cores. Lead isotope ratios in the bone core digests (and burial soils) were measured by multi-collector ICPMS. It was found that concentrations of lead in the Roman/Londinium-era femora were > 70-fold greater than those from pre-Roman populations. This was confirmed by femoral data obtained from the analysis of a pre-Roman burial from the early first century bc found adjacent to the Southern Cemetery. Several major and trace element metrics for diagenesis demonstrate that levels of lead in the bone are robust indicators of human exposure during life. Lead isotope data for the Roman population are consistent with previously identified widespread lead pollution. The pre-Roman populations contain lead isotopic compositions consistent with highly localized, minor sources of lead. Together, these data provide unequivocal confirmation that the Romans in Londinium were exposed to elevated lead levels. Elevated blood lead levels would have resulted, negatively affecting their health and possibly contributing to declining birth rates.     

Storage in traditional farming communities of the western Mediterranean: Ethnographic,historical and archaeological data

Abstract

This paper presents ethnographic, historic and archaeological data from the western Mediterranean in order to explore the variability of storage methods and the various strategies that may have existed in the past in this region. The paper includes ethnographic information on traditional storage methods collected in farming communities in northern Morocco (Rif area). We record the use of plant fibres such as canes (Arundo donax), dwarf palm (Chamaerops humilis), esparto grass (Stipa tenacissima) and dis (Ampelodesmos mauritanica) to make containers. Recipients made of cow dung and unfired clay, as well as underground silos, have been also used in this region to store food. In addition, we explore historical and ethnohistorical data on the use of large storage structures, including the study of communal granaries, a particular type of granary located at inaccessible places, such as cliff faces or mountain tops, or within fortified buildings, from which harvests can be easily protected and defended. We also examine the archaeological evidence of storage strategies in the Iberian Peninsula during prehistoric times. The paper informs of the large variety of systems and materials used, the functioning of storage structures, and more generally, provides a framework for reflecting on the enormous diversity of solutions that could have existed in the past and that may have left little or none archeological traces.     

Late Holocene climatic fluctuations and soil genesis in southern Patagonia: effects on the archaeological record

Geoarchaeological research conducted at five localities in southern Patagonia and Tierra del Fuego identified a mollisol within late Holocene aeolian and colluvial deposits associated with archaeological material. The mollisol's origin and development are related to an increase in humidity (c. 1000 BP) following an episode of severe drought during the Medieval Warm Period. Corroborating data is supplied from dendroclimatic and pollen studies. A drastic reduction in frequency of artefact distribution recorded at the sites studied corresponds to this pedologic event, suggesting a greater human presence at these sites during earlier, regional-scale arid conditions. However, the paucity of archaeological remains may also be the result of the low resolution of cultural evidence following the pedologic development due to superimposition over previous archaeological deposits.     

Climate deterioration and land-use change in the first millennium BC: perspectives from the British palynological record

Climate deterioration at around the time of the Bronze Age/Iron Age transition has for long been argued to have resulted in upland abandonment in northern and western Britain, and recent research has provided evidence that a major climate downturn from 850 cal BC caused settlement abandonment in western Europe and potentially worldwide. It is, however, unclear to what extent only ‘marginal’ sites were affected, due to the lack of any systematic attempt to view the evidence for settlement and land-use change across a range of landscape types with differing sensitivities to environmental change. This paper addresses this issue by an evaluation of 75 pollen sequences spanning the late Bronze Age and early Iron Age in Britain to assess whether climatic deterioration was sufficient to cause widespread land abandonment. The results provide no evidence for wholesale land-use change at this time; the overall picture is one of continuity of land use or even increased agricultural activity. There are, however, hints of regional variability, with a greater tendency to abandonment of upland areas in Wales, and signs of woodland regeneration in agriculturally productive areas of lowland central southern England. The latter pattern may reflect a combination of rising ground-water levels affecting local land-use in the immediate vicinity of the mires which provide the source of the pollen data, against a backdrop of regional-scale social and economic changes at the Bronze Age-Iron Age transition.     

Life on the Edge of the Arctic: The Bioarchaeology of the Keldudalur Cemetery in Skagafjörður,Iceland

Burials were examined from the late Viking Age early medieval Christian cemetery at the farm of Keldudalur in the Skagafjörður region, Northern Iceland. The cemetery likely served a single household for about 100–120 years, from the beginning of the 11th century AD to the turn of the 12th century. Cemetery inhabitants represent a population that lived through the transitional period when Christianity was established in Iceland. The changes are visible in the mortuary record with the changeover from outlying pagan graves to enclosed Christian cemeteries situated on the farmsteads. Keldudalur is one of the numerous early Christian family cemeteries that littered the 11th century Skagafjörður landscape. The burials included 53 well‐preserved skeletons of 27 adults and 26 subadults. Various factors such as fluctuating climate and environmental conditions, and seasonal or periodical availability of resources have the potential for impacting human diet and health over time. To assess the health status of the burials, data were collected for a number of health status indicators such as stature estimation, developmental enamel defects, porotic hyperostosis, infectious disease, trauma, degenerative joint diseases, dental caries, calculus and tooth loss. Results suggest that inhabitants of Keldudalur experienced periodic stress and rigorous living conditions. Infant mortality was great, although if individuals survived childhood, the age expectancy was fairly high. There was no obvious evidence for interpersonal violence or endemic infectious disease. However, the common occurrence of growth disturbances, generalised periostitis, trauma and degenerative joint disease all point to a number of stressors in the lives of the people at Keldudalur, which is suggestive of a resilient people living and adapting to a harsh and periodically resource scarce subarctic environment.

Borders,planning and policy transfer: historical transformation of development discourses in the Finnish Torne Valley

European Union spatial policies have become a key institutional context in which to study policy transfer processes in European border areas. These policies are, however, only the most recent part of these transformation processes which raises a need for more historically sensitive approaches. An historical perspective is important, since border regions are historical processes with particular path-dependent development trajectories and power structures. This paper aims to contribute to the discussion concerning the transformation of European border regions by looking at the policy transfer of regional development discourses in the Finnish Torne Valley. The study material consists of strategic development documents produced by the Finnish border municipalities and the municipal-based co-operation organizations from the 1930s to 2013. The examination, based on critical discourse analysis, shows that the transformation process is driven by national trends and the dominant planning discourse. Nevertheless, the particular border setting and local discourse on ‘united Torne Valley’ have also intertwined with political and economic processes during different time periods.     

The southern dispersal hypothesis and the South Asian archaeological record: Examination of dispersal routes through GIS analysis

This research advances a model for coastal-based dispersals into South Asia during oxygen isotope stage (OIS) 4. A series of GIS-based analyses are included that assess the potential for expansions into the interior of South Asia, and these results are compared with known archaeological signatures from that time period. The results suggest that modern Homo sapiens could have traversed both the interior and coastlines using a number of routes, and colonized South Asia relatively rapidly. Use of these routes also implies a scenario in which modern H. sapiens, by either increased population growth or competitive ability, may have replaced indigenous South Asian hominin populations.     

Identity and state formation in multi‐sectarian societies: Between nationalism and sectarianism in Syria

The relation between state formation and identity in MENA multi‐sectarian societies is examined, taking Syria as a case study. The paper looks at the impact of the mix of sectarianism and nationalism on the formation of state institutions and the impact of the latter on this mix. The flawed export of the Westphalian state system to MENA established the structural context—multiple identities, hybrid states—wherein the two identities compete, overlap, and coexist. Next, the factors that explain varying identity patterns in MENA are surveyed and their likely consequences for state formation; then, reversing the analysis, the impact of state formation and state institutions on the nationalism–sectarianism balance is examined. The Syrian case is briefly discussed in order to illustrate the argument, looking at three periods when the identity balance interacted differently with state formation: pre‐Ba'thist Syria when nationalism eclipsed sectarianism; Ba'thist Syria (1970‐2000) when patrimonial instrumentalization of sectarianism was compensated for by inclusive bureaucratic institutions, populist policies, and nationalist ideology; neo‐liberal Syria under Bashar al‐Asad (2000‐2010) when inclusion shrank, reanimating sectarianism; and civil war Syria (2010‐) when partial state failure fostered exclusionary militant sectarianism at the expense of nationalism.     

The historical origins of the vegetative state: Received wisdom and the utility of the text

The persistent vegetative state (PVS) is one of the most iconic and misunderstood phrases in clinical neuroscience. Coined as a diagnostic category by Scottish neurosurgeon Bryan Jennett and American neurologist Fred Plum in 1972, the phrase “vegetative” first appeared in Aristotle’s treatise On the Soul (circa mid-fourth century BCE). Aristotle influenced neuroscientists of the nineteenth and early-twentieth centuries, Xavier Bichat and Walter Timme, and informed their conceptions of the vegetative nervous system. Plum credits Bichat and Timme in his use of the phrase, thus putting the ancient and modern in dialogue. In addition to exploring Aristotle’s definition of the “vegetative” in the original Greek, we put Aristotle in conversation with his contemporaries—Plato and the Hippocratics—to better apprehend theories of mind and consciousness in antiquity. Utilizing the discipline of reception studies in classics scholarship, we demonstrate the importance of etymology and historical origin when considering modern medical nosology.     

Late Holocene human impact on the vegetation around Mizorogaike Pond in northern Kyoto Basin,Japan: a comparison of pollen and charcoal records with archaeological and historical data

Pollen and macroscopic charcoal analyses of AMS radiocarbon-dated sediment from Mizorogaike Pond, located near Japan’s ancient capital established in AD 794, were used along with archaeological and historical data to reconstruct vegetation change in the northern Kyoto Basin since 7300 cal yr B.P. Between ca. 7300 and 3400 cal yr B.P. (Early to Late Jomon period), the site was surrounded by warm-temperate forest composed of Quercus subgenus Lepidobalanus and Q. subgenus Cyclobalanopsis with Celtis/Aphananthe trees. With the occurrence of fire disturbance, Q. subgenus Lepidobalanus increased from ca. 3400 to 1400 cal yr B.P. (Late Jomon to Kofun periods). In the early seventh century (Asuka period), Pinus started to increase, coinciding with a significant charcoal peak, probably related to the operation of roof tile kilns near the site. Pinus continued to increase and Q. subgenus Cyclobalanopsis decreased through the seventh to tenth centuries (Asuka to Heian periods). Further increase of Pinus occurred in the eleventh century, possibly reflecting the establishment of the manor of Kamigamo Shrine. From the eleventh to seventeenth centuries (Heian to medieval periods), no significant vegetational change or fire disturbance took place. In the eighteenth century, the landscape became totally open, with poor vegetation and sparse Pinus woodland. The medieval and early modern landscapes reconstructed from the palaeoecological record are rather similar to those described from studies of ancient artwork and historical documents. This study demonstrates that late Holocene vegetation change in the northern Kyoto Basin was closely tied to anthropogenic activities, such as the pottery industry and fuel wood collection.     

Job polarization in the new economy in Danish cities: location,size, and the role of the public sector

ABSTRACT

In this paper we examine the geographic patterns of employment growth and employment polarization in small and medium-sized cities (SMCs) in Denmark during the rise of the new economy. The geography of employment polarization in Danish cities is examined using register-based employment data on occupations and wages divided into the public and private sectors in the period 1993–2006; it therefore covers a long period of transformation and growth in the Danish economy. We conclude that employment growth is characterized by employment polarization combined with growth in low- and high-wage employment and a decline in medium-wage employment. However, these patterns of polarization differ across the public and private sectors, as well as by geography. While local labour market (LLM) size, city position and city specialization influence the geography of private-sector employment growth and polarization, municipal population and composition influence the geography of public-sector growth patterns across wage levels. Finally, public and private employment are positively associated within SMCs, predominantly driven by the positive association between public employment and private-sector low-wage employment. However, public employment is not associated with an increase in private low-wage employment in more remote areas.     

Organic residue analysis of Iron Age ceramics from the archaeological site of Kani-zirin,western Iran

Organic residue analysis of potshards excavated from the Iron Age archaeological site of Kani-zirin, western Iran, was achieved with acidified methanol extraction and gas chromatography-mass spectrometry (GC-MS). The GC-MS data showed plant and animal commodities incorporated in the shards. Also, the investigations confirmed the presence of plant resin together with a tartrate ion within a group of the shards, suggesting a probable use of grape-related products. Evidence of resins from the Pinaceae family, as an exotic species in Iran, was evinced in several of the shards.     

To binarize or not to binarize: relational data and the construction of archaeological networks

Over the last several years, network methods and models from the social and physical sciences have gained considerable popularity in archaeology. Many of the most common network methods begin with the creation of binary networks where links among some set of actors are defined as either present or absent. In most archaeological cases, however, the presence or absence of a specific kind of relationship between actors is not straightforward as we must rely on material proxies for assessing connections. A common approach in recent studies has been to define some threshold for the presence of a tie by partitioning continuous relational data among sites (e.g., artifact frequency or similarity data). In this article, using an example from the U.S. Southwest, we present a sensitivity analysis focused on the potential effects of defining binary networks from continuous relational data. We show that many key network properties that are often afforded social interpretations are fundamentally influenced by the assumptions used to define connections. We suggest that, although network graphs provide powerful visualizations of network data, methods for creating and analyzing weighted (non-binarized) networks often provide a better characterization of specific network properties.     

Phytolith-rich layers from the Late Bronze and Iron Ages at Tel Dor (Israel): mode of formation and archaeological significance

The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods.     

Tracking changes in bone fracture morphology over time: environment, taphonomy, and the archaeological record

Zooarchaeologists have often employed studies of bone fracture morphology as a means of understanding past human cultural activity, and various methodological approaches have been developed for analyzing archaeological broken bone assemblages. It is widely understood that bones degrade over time, however, few studies have attempted to define and quantify the rate at which bones degrade and fracture morphologies change. This study examines degradation in frozen bones (−20 °C) and bones exposed to hot (40 °C) dry conditions. These two simulated environmental conditions represent extreme real-world climates, and allow for an actualistic understanding of the rates of degradation that bones experience in nature. When frozen, bones degrade slowly but significantly, and demonstrate measurable differences in samples frozen for 1, 10, 20, 40, and 60 weeks. In hot, dry conditions, bones degrade very quickly, and demonstrate measurable differences after 1, 3, 7, 14, and 21 days. These data allow for a more detailed understanding of the relationship between the cultural and natural processes that result in bone fracture, and the time period during which bones can be expected to maintain fresh fracture characteristics. This research also has implications for understanding human subsistence and survival strategies and for interpreting the archaeological record.     

Ethics of heritage: locating the punitive state in the historical penal landscape of Taipei

Research into prison tourism and prison heritage has not taken enough time to understand how historical change has left impacts in urban contexts, which sometimes continues even after the prisons are decommissioned. This paper discusses the punitive state in the context of the historical penal landscape of Taipei through an exploration of how an historical prison was designed, built, partially demolished, preserved and redeveloped under three political regimes. It draws attention to the neglected relationships between punishment, colonial modernity and heritage. Drawing on the literature of dissonant heritage and dark tourism it argues that the way in which the government erased the heritage and evicted squatters without regard for colonial histories and large-scale, post-war migration is yet another way of writing imprisonment into the landscape and ‘othering’ the punished. Furthermore, in tracing the place memories, both within and outside of the high prison walls, it demonstrates the possibilities offered by ethics of heritage, with which we may counter the culture of punishment in the remaking of cities.     

Imaging skeletal remains with ground-penetrating radar: comparative results over two graves from Viking Age and Medieval churchyards on the Stóra-Seyla farm,northern Iceland

Detailed ground-penetrating radar surveys were conducted at separate Viking Age and Medieval churchyards on the Stóra-Seyla farm in Skagafjörður, northern Iceland. Surveying over a previously unknown site (ca. AD 1000) that is located just a few meters above the Skagafjörður valley bottom delineated the remnants of a buried circular turf wall that encloses a church structure and several graves. The radar profiles over the graves contain strong hyperbolic reflections that emanated from the skeletal remains. Over one of the graves, an air-filled void within the chest cavity had been detected as noted by reflections with normal polarity which indicated a boundary towards increasing microwave velocity. During excavation, the soil surrounding an intact rib cage collapsed thus confirming the presence of the void. In general, the skeletal remains were very well preserved and yielded strong reflections which permitted the orientation of the body to be determined. Conversely, the radar profiles over a grave from a more recent churchyard (ca. AD 1200) show ground disturbance but lack hyperbolic reflections. Upon excavation, only teeth were recovered. The poor preservation of the skeletal remains is attributed to increase contact with infiltrating groundwater from an overlying gravel layer. Interpretations were aided by time-slice overlay imaging, forward modeling and analysis of the reflection coefficient.     

Kin state non‐interventionism: Albania and regional stability in the Western Balkans

This article provides a comprehensive analysis of Albanian regional policy from 1992 to 2013. Situated in a conflict‐ridden region and surrounded by co‐ethnics living in Kosovo, Macedonia, Montenegro and Serbia, Albania has successfully resisted pressure to undertake interventionist regional policies. However, there are no structured accounts as to how Albania fashioned its non‐interventionist regional policy. This article fills this gap and retraces the development of Albanian regional policy as a function of its inter‐mingled domestic politics and regional and international dynamics. The article concludes that the Albanian regional approach has been shaped by its legacy of communist isolation, pro‐Western predisposition and recognition that accommodation of Western interests would overcome its constraints and advance the rights of Albanians living in the Western Balkans. The analysis is important not just for understanding Albania's actions but also for disentangling the relationship between regional policy, nationalism and a kin state's domestic and international constraints.
