High-precision radiocarbon dating and historical biblical archaeology in southern Jordan

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 Edoms 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.

A New Chronological Framework for Iron Age Copper Production at Timna (Israel)

This paper presents the results of the 2009 excavations at Site 30 in the Timna Valley, Israel. The results, coupled with a suite of 11 new radiocarbon dates, fix the chronology of the site between the 11th and 9th centuries B.C.E. and challenge the previous chronological framework of the copper production activities in the southern Arabah Valley. The paper also presents a striking correlation between Site 30 and the recently reported archaeological record of Iron Age Faynan, indicating technological and social unity between the two regions. In light of the new results and reexamination of previously published materials, we suggest that the peak in copper production in the southern Arabah occurred after the Egyptians had left their small outpost at Timna; this activity was an offshoot of the more elaborate enterprise at Faynan. The well-organized Iron Age copper production in the Arabah Valley was based on local initiatives and conducted by local seminomadic tribes, probably belonging to the Edomite polity.

Decadal-scale variations in geomagnetic field intensity from ancient Cypriot slag mounds

Geomagnetic models based on direct observations since the 1830s show that the averaged relative change in field intensity on Earths surface over the past 170 years is less than 4.8% per decade. It is unknown if these rates represent the typical behavior of secular variations due to insufficient temporal resolution of archaeomagnetic records from earlier periods. To address this question, we investigate two ancient slag mounds in Cyprus—Skouriotissa Vouppes (SU1, fourth to fifth centuries CE, 21 m in height), and Mitsero Kokkinoyia (MK1, seventh to fifth centuries BCE, 8 m in height). The mounds are multilayered sequences of slag and charcoals that accumulated near ancient copper production sites. We modeled the age-height relation of the mounds using radiocarbon dates, and estimated paleointensities using Thellier-type IZZI experiments with additional anisotropy, cooling rate, and nonlinear TRM assessments. To screen out ambiguous paleointensity interpretations, we applied strict selection criteria at the specimen/sample levels. To ensure objectivity, consistency, and robust error estimation, we employed an automatic interpretation technique and put the data available in the MagIC database. The analyses yielded two independent subcentury-scale paleointensity time series. The MK1 data indicate relatively stable field at the time the mound accumulated. In contrast, the SU1 data demonstrate changes that are comparable in magnitude to the fastest changes inferred from geomagnetic models. We suggest that fast changes observed in the published archaeomagnetic data from the Levant are driven by two longitudinally paired regions, the Middle East and South Africa, that show unusual activity in geomagnetic models.

The Introduction of Domestic Camels to the Southern Levant: Evidence from the Aravah Valley

Abstract It was recently suggested that the introduction of the camel to the southern Levant occurred in the early Iron Age (late 2nd-early 1st millennia BCE). Our study of faunal remains from Iron Age sites at Timna, together with previous studies of Late Bronze and Iron Age sites at Timna and Wadi Faynan, enable us to pinpoint this event more precisely. The new evidence indicates that the first significant appearance of camels in the Aravah Valley was not earlier than the last third of the 10th century BCE. This date accords with data from the Negev and the settled lands further to the north when the low chronology is applied to the early Iron IIA.

Six centuries of geomagnetic intensity variations recorded by royal Judean stamped jar handles

Significance Understanding the geomagnetic field behavior in the past, and, in particular, its intensity component, has implications for various (and disparate) fields of research, including the physics of Earth’s interior, atmospheric and cosmologic sciences, biology, and archaeology. This study provides substantial data on variations in geomagnetic field intensity during the eighth to second centuries BCE Levant, thus significantly improving the existing record for this region. In addition, the study provides further evidence of extremely strong field in the late eighth century BCE (“geomagnetic spike”), and of rapid rates of change (>20% over three decades). The improved Levantine record is an important basis for geophysical models (core−mantle interactions, cosmogenic processes, and more) as well as a reference for archaeomagnetic dating. Earth’s magnetic field, one of the most enigmatic physical phenomena of the planet, is constantly changing on various time scales, from decades to millennia and longer. The reconstruction of geomagnetic field behavior in periods predating direct observations with modern instrumentation is based on geological and archaeological materials and has the twin challenges of (i) the accuracy of ancient paleomagnetic estimates and (ii) the dating of the archaeological material. Here we address the latter by using a set of storage jar handles (fired clay) stamped by royal seals as part of the ancient administrative system in Judah (Jerusalem and its vicinity). The typology of the stamp impressions, which corresponds to changes in the political entities ruling this area, provides excellent age constraints for the firing event of these artifacts. Together with rigorous paleomagnetic experimental procedures, this study yielded an unparalleled record of the geomagnetic field intensity during the eighth to second centuries BCE. The new record constitutes a substantial advance in our knowledge of past geomagnetic field variations in the southern Levant. Although it demonstrates a relatively stable and gradually declining field during the sixth to second centuries BCE, the new record provides further support for a short interval of extreme high values during the late eighth century BCE. The rate of change during this “geomagnetic spike” [defined as virtual axial dipole moment > 160 ZAm2 (1021 Am2)] is further constrained by the new data, which indicate an extremely rapid weakening of the field (losing ∼27% of its strength over ca. 30 y).

The socioeconomic status of Iron Age metalworkers: animal economy in the "Slaves Hill", Timna, Israel

The popular image of metalworking sites in desert settings envisages armies of slaves engaged in back-breaking labour. This is in conflict with ethnographic evidence indicating that skilled specialist metalworkers are often accorded high social status. This study approaches that contradiction directly by studying the remains of domesticated food animals from domestic and industrial contexts at Timna in southern Israel. The authors demonstrate that the higher-value meat cuts come from industrial contexts, where they were associated with the specialist metalworkers, rather than the ‘domestic’ contexts occupied by lower status workers engaged in support roles. It is suggested that the pattern documented here could also have been a feature of early metalworking sites in other times and places.

Late Bronze Age copper production in Timna: new evidence from Site 3

This paper presents for the first time results of two excavation seasons conducted in 1979 and 1984 by the Arabah Expedition at one of the major smelting camps in the copper ore district of Timna. The results, together with new radiocarbon dates of short-lived samples from the site, demonstrate that copper production during the Late Bronze Age (13th to the first half of 12th centuries BC) was undertaken on a relatively small scale in demilitarized camps, systematically organized in a distinct area at the northern part of the Timna Valley. This production system should be associated with the Egyptian presence in the region, represented by the nearby Hathor Shrine. The new data from Site 3 also shed light on the transition to the Iron Age, a period when production peaked in the entire Arabah Valley as new copper production systems were established, replacing their predecessors entirely.

A Rejoinder on the Value of Archaeomagnetic Dating: Integrative Methodology Is the Key to Addressing Levantine Iron Age Chronology

Archaeomagnetic dating is a firmly established dating technique applicable to a wide variety of heat-treated anthropological materials and is advantageous for sites that lack materials suitable for radiocarbon dating. To correct recent misinterpretations of the method, we provide examples of how archaeomagnetic dating curves are calibrated and show how, in some instances, the technique can provide superior results. We emphasize that no single dating technique is capable of resolving the challenging chronology controversies in the Levant, and instead argue that multiple dating methods must be integrated in order to achieve the highest possible temporal resolution.

A ‘SMALL TOWN’ DISCOVERED TWICE: A FORGOTTEN REPORT OF MAJOR H. H. KITCHENER

Abstract This paper revisits the contribution of the Palestine Exploration Fund (PEF) to the study of the ancient copper mines of Faynan, Jordan. It reveals that it was a PEF expedition that first reported smelting remains in the northern part of the Faynan region, and demonstrates that the reported remains are the Iron Age site of Khirbat al-Jariya.

Early evidence (late 2nd millennium BCE) of plant-based dyeing of textiles from Timna, Israel

Abstract In this article, we focus on the analysis of dyed textile fragments uncovered at an early Iron Age (11th-10th centuries BCE) copper smelting site during new excavations in the Timna Valley conducted by the Central Timna Valley (CTV) Project, as well as those found by the Arabah Expedition at the Hathor Temple (Site 200), dated to the Late Bronze/early Iron Ages (13th-11th centuries BCE). Analysis by HPLC-DAD identified two organic dyestuffs, Rubia tinctorum L. and indigotin, from a plant source (probably Isatis tinctoria L.). They are among the earliest plants known in the dyeing craft and cultivated primarily for this purpose. This study provides the earliest evidence of textiles dyed utilizing a chemical dyeing process based on an industrial dyeing plant from the Levant. Moreover, our results shed new light on the society operating the copper mines at the time, suggesting the existence of an elite that was interested in these high quality textiles and invested efforts in procuring them by long-distance trade.
