[1] Paleointensity and archaeointensity studies since the 1950s have produced numerous geomagnetic intensity data for the last seven millennia. As a consequence of different experiments and materials, there is a complex and internally inconsistent picture of the geomagnetic field behavior. In this study we present data using a recently developed experimental design on a heretofore unexploited recording medium: copper slag deposits. Our results, based on hundreds of specimens from various archaeometallurgical sites of the Southern Levant, demonstrate the applicability of copper slag material for archaeointensity studies. In addition to frequently exhibiting good experimental behavior, slag has further advantages such as dense multilayer deposits and in cases embedded charcoals, which open the door to data sets with excellent age control and resolution. The data presented here augment the high quality database from the Middle East and support previously observed periods of rapid change of the intensity of the geomagnetic field.

An international team of researchers show how high-precision radiocarbon dating is liberating us from chronological assumptions based on Biblical research. Surface and topographic mapping at the large copper-working site of Khirbat en-Nahas was followed by stratigraphic excavations at an ancient fortress and two metal processing facilities located on the site surface. The results were spectacular. Occupation begins here in the eleventh century BC and the monumental fortress is built in the tenth. If this site can be equated with the rise of the Biblical kingdom of Edom it can now be seen to: have its roots in local Iron Age societies; is considerably earlier than previous scholars assumed; and proves that complex societies existed in Edom long before the influence of Assyrian imperialism was felt in the region from the eighth – sixth centuries BC.

Recent excavations and high-precision radiocarbon dating from the largest Iron Age (IA, ca. 1200 -500 BCE) copper production center in the southern Levant demonstrate major smelting activities in the region of biblical Edom (southern Jordan) during the 10th and 9th centuries BCE. Stratified radiocarbon samples and artifacts were recorded with precise digital surveying tools linked to a geographic information system developed to control on-site spatial analyses of archaeological finds and model data with innovative visualization tools. The new radiocarbon dates push back by 2 centuries the accepted IA chronology of Edom. Data from Khirbat en-Nahas, and the nearby site of Rujm Hamra Ifdan, demonstrate the centrality of industrial-scale metal production during those centuries traditionally linked closely to political events in Edom's 10th century BCE neighbor ancient Israel. Consequently, the rise of IA Edom is linked to the power vacuum created by the collapse of Late Bronze Age (LB, ca. 1300 BCE) civilizations and the disintegration of the LB Cypriot copper monopoly that dominated the eastern Mediterranean. The methodologies applied to the historical IA archaeology of the Levant have implications for other parts of the world where sacred and historical texts interface with the material record.archaeometallurgy ͉ social evolution ͉ Iron Age ͉ Levant ͉ StarCAVE

Recent excavations at Pre-Pottery Neolithic A (PPNA) WF16 in southern Jordan have revealed remarkable evidence of architectural developments in the early Neolithic. This sheds light on both special purpose structures and "domestic" settlement, allowing fresh insights into the development of increasingly sedentary communities and the social systems they supported. The development of sedentary communities is a central part of the Neolithic process in Southwest Asia. Architecture and ideas of homes and households have been important to the debate, although there has also been considerable discussion on the role of communal buildings and the organization of early sedentarizing communities since the discovery of the tower at Jericho. Recently, the focus has been on either northern Levantine PPNA sites, such as Jerf el Ahmar, or the emergence of ritual buildings in the Pre-Pottery Neolithic B of the southern Levant. Much of the debate revolves around a division between what is interpreted as domestic space, contrasted with "special purpose" buildings. Our recent evidence allows a fresh examination of the nature of early Neolithic communities.forager-farmer transition | Near East T he Pre-Pottery Neolithic A (PPNA) is the earliest Neolithic in Southwest Asia (circa 11,600 to 10,200 y ago) situated between hunting and gathering and sedentary farming societies. It is generally considered as the key period in the shift to management and production of resources, wherein increasingly sedentary communities start to produce food to extend the period of occupation at a site, with one of the main economic developments in the PPNA being the cultivation of wild cereals. Social changes are as significant as economic ones, enabling communities to both increase in size and live together for longer periods, and, arguably, it is these social changes that drive the economic developments. Architecture is an important facet of the early Neolithic, providing evidence for an increasingly sedentary lifestyle; changing social structures; and, in the growth of communities, a motive for the development of food production.Three basic assumptions tend to be made regarding PPNA settlements: (i) that the presence of stone or mud architecture indicates sedentism; (ii) that most buildings are domestic and can be described as houses forming small permanent villages; and (iii) that any buildings not fitting this pattern are "special," with some communal function, frequently assumed to be ritual as opposed to a domestic norm, including the tower at Jericho (1), monumental stone-pillared structures at Göbekli Tepe (2), and communal buildings at Jerf el Ahmar and Mureybet (3). On the basis of our recent discoveries at WF16, we argue that these normative assumptions must be questioned. Can we really identify basic domestic structures in these early settlements, and do they exist in opposition to the nondomestic? This has profound implications for how we understand PPNA social organization.Strong arguments have been made that the PPNA is part of a long, sl...
