Storm flooding,coastal defence and land use around the Thames estuary and tidal river c.1250–1450

Climatic deterioration in the later middle ages was associated with an increasing frequency of marine storm surges affecting the coasts of the southern North Sea. This paper investigates the impact of storm surges upon the lands bordering the Thames estuary and tidal river between the mid-thirteenth and mid-fifteenth centuries. Land use in the coastal and riverine marshes is reviewed, and the means and costs of defence against marine flooding explored. The impact of flooding upon human use of the marshlands, upon the suburbs of medieval London and upon the Thames fisheries are all investigated. Stress is placed upon the complex interaction of economic and environmental factors in determining the response to the threat of marine flooding.     

Full‐Vector Archaeomagnetic Dating of a Medieval Limekiln at Pinilla Del Valle Site (Madrid,Spain)

Archaeomagnetic dating based on the full geomagnetic field vector was carried out on a limekiln excavated at Pinilla del Valle archaeological site (Madrid, Spain). The limekiln tradition in this area is largely documented by historical sources for recent centuries but the date of the studied kiln's last use was unknown. The combination of mean archaeomagnetic directional and absolute archaeointensity results shows that the kiln was last used between ad 1296 and 1413, in good agreement with two independent radiocarbon dates. This study provides the first archaeomagnetic evidence that the local limekiln tradition dates back to at least late medieval times. Furthermore, the inclusion of these data in the Iberian secular variation curve and geomagnetic field models will help to improve the archaeomagnetic dating technique.     

Analyses of Early Medieval Stained Window Glass From the Monastery of Baume‐Les‐Messieurs (Jura,France)

The collection of early medieval window glass found in the abbey of Baume‐les‐Messieurs (Jura, France) is exceptional because it dates to the end of the eighth century, and due to the number of fragments as well as their state of conservation. Different colours and forms have been identified. These pieces are a rare opportunity to address the glass craft, its recipes and techniques for a phase of its history that has remained little known. Analyses in PIXE–PIGE prove that, in addition to fragments from two soda glass items, the pieces are made from wood‐ash glass. Most of them probably came from the same production and the raw material is present in the region. At this early stage of wood‐ash glass production, the glassmakers had mastered the glass as well as the colour processes.     

New radiometric ages for the Fauresmith industry from Kathu Pan,southern Africa: Implications for the Earlier to Middle Stone Age transition

The Fauresmith lithic industry of South Africa has been described as transitional between the Earlier and Middle Stone Age. However, radiometric ages for this industry are inadequate. Here we present a minimum OSL age of 464 ± 47 kyr and a combined U-series–ESR age of 542₋₁₀₇⁺¹⁴⁰ kyr for an in situ Fauresmith assemblage, and three OSL ages for overlying Middle and Later Stone Age strata, from the site of Kathu Pan 1 (Northern Cape Province, South Africa). These ages are discussed in relation to the available lithostratigraphy, faunal and lithic assemblages from this site. The results indicate that the Kathu Pan 1 Fauresmith assemblage predates transitional industries from other parts of Africa e.g. Sangoan, as well as the end of the Acheulean in southern Africa. The presence of blades, in the dated Fauresmith assemblages from Kathu Pan 1 generally considered a feature of modern human behaviour ( McBrearty and Brooks, 2000, The revolution that wasn't: a new interpretation of the origin of modern human behavior, J. Human Evolution 39, 453–563),-provides evidence supporting the position that blade production in southern Africa predated the Middle Stone Age and the advent of modern Homo sapiens.

New Bioarchaeological Evidence and Radiocarbon Dates from the Lambayeque/Sicán Culture Camelids from the El Brujo Complex (Northern Coast of Peru): Implications for Funerary and Herd Management Practices

ABSTRACT

Pastoralism and camelid management have been essential to all aspects of pre-Hispanic Andean societies. Here, we present zooarchaeological and isotopic data on domestic camelid remains from Huaca Cao Viejo (El Brujo archaeological complex) on the northern coast of Peru, and dated to the Lambayeque/Sicán period—to characterise their biological age, diet, life history, possible geographic origin and ritual use. Domestic camelids, representing a wide range of biological ages and a high rate of polydactyly, were found as burial offerings in direct association with human funerary bundles (fardos). Direct AMS dates indicated that camelids were buried over a short period of time (AD 1022–1176) confirming the Lambayeque presence in the Chicama Valley during the first half of the Late Intermediate Period. Stable isotopic analyses were carried out on both bone collagen and hair keratin, including incremental analysis. A considerable variability in δ¹³C values at both the intra-individual and the intra-group level and a large contribution of C₄ resources to diet are shown. This clearly supports local management and camelids originating from various herds. Zooarchaeological and isotopic evidences suggest diversity in herding practices and suggest the importance of the herds in fulfilling the transportation demands for trade in goods.     

Identifying integrative built environments in the archaeological record: An application of New Urban Design Theory to ancient urban spaces

Ancient Maya settlement patterns have long been described as dispersed. Instances of low-density or dispersed urbanism among agrarian-based societies are common in tropical civilizations, and are of particular interest due to their expressed problem of social integration. Traditionally, archaeologists have focused on classic hallmarks of state integration, including force, infrastructural control, large-scale ritual, and kinship; thus, reflecting the polar extremes of integration. Current models accord a more multi-scalar and dynamic nature to state and urban organization, and the need to pursue diachronic perspectives that consider more subtle and varied degrees of integration. With regard to settlement, examining the total patch of occupation on a landscape, how it developed, how it was divided up, and in turn brought together, is of interest. In this study I apply criteria developed in New Urban Design Theory, a body of thought and practice concerned with modern-day issues of dispersed and low density settlement, to evaluate an architectural complex at the Classic Maya centre of Buenavista del Cayo, Belize, believed to have functioned as an integrative space within the civic entity.
