Archaeometric evidence for the earliest exploitation of lignite from the bronze age Eastern Mediterranean.

This paper presents the earliest evidence for the exploitation of lignite (brown coal) in Europe and sheds new light on the use of combustion fuel sources in the 2nd millennium BCE Eastern Mediterranean. We applied Thermal Desorption/Pyrolysis-Gas Chromatography-Mass Spectrometry and Polarizing Microscopy to the dental calculus of 67 individuals and we identified clear evidence for combustion markers embedded within this calculus. In contrast to the scant evidence for combustion markers within the calculus samples from Egypt, all other individuals show the inhalation of smoke from fires burning wood identified as Pinaceae, in addition to hardwood, such as oak and olive, and/or dung. Importantly, individuals from the Palatial Period at the Mycenaean citadel of Tiryns and the Cretan harbour site of Chania also show the inhalation of fire-smoke from lignite, consistent with the chemical signature of sources in the northwestern Peloponnese and Western Crete respectively. This first evidence for lignite exploitation was likely connected to and at the same time enabled Late Bronze Age Aegean metal and pottery production, significantly by both male and female individuals.

Exotic foods reveal contact between South Asia and the Near East during the second millennium BCE.

Although the key role of long-distance trade in the transformation of cuisines worldwide has been well-documented since at least the Roman era, the prehistory of the Eurasian food trade is less visible. In order to shed light on the transformation of Eastern Mediterranean cuisines during the Bronze Age and Early Iron Age, we analyzed microremains and proteins preserved in the dental calculus of individuals who lived during the second millennium BCE in the Southern Levant. Our results provide clear evidence for the consumption of expected staple foods, such as cereals (Triticeae), sesame (Sesamum), and dates (Phoenix). We additionally report evidence for the consumption of soybean (Glycine), probable banana (Musa), and turmeric (Curcuma), which pushes back the earliest evidence of these foods in the Mediterranean by centuries (turmeric) or even millennia (soybean). We find that, from the early second millennium onwards, at least some people in the Eastern Mediterranean had access to food from distant locations, including South Asia, and such goods were likely consumed as oils, dried fruits, and spices. These insights force us to rethink the complexity and intensity of Indo-Mediterranean trade during the Bronze Age as well as the degree of globalization in early Eastern Mediterranean cuisine.

A 3000 year old case of an unusual dental lesion: Pre-eruptive intracoronal resorption.

OBJECTIVE: To determine the cause of a large dental lesion, tentatively identified as a case of pre-eruptive intra-coronal resorption (PEIR), in the permanent second mandibular molar of a young individual from an Iron Age cemetery at Tel Erani (Israel), dated to ca. 3000 years B.P. The provisional diagnosis was based on the massive size of the lesion in a young individual in whom the adjacent teeth were caries-free and showed no visible enamel defects. DESIGN: The lower molars of Tel Erani on the affected side were radiographed and compared to radiographs of a modern clinical case of PEIR treated by one of us (U.Z) and the internal structure and mineral content of the lesion examined in detail using energy-dispersive X-ray spectroscopy (EDS). RESULTS: The Tel Erani specimen closely resembled the modern clinical case of PEIR. Moreover, both cases occurred in young individuals in whom the adjacent teeth were caries-free. Examination with SEM revealed absence of dentine in the affected tooth from Tel Erani, together with changes in structure and mineral content characteristic of resorption. CONCLUSIONS: Our study shows that the changes found in the lower second molar of the 3000 year old mandible from Tel Erani are characteristic of PEIR and demonstrate the antiquity of this condition.

The onset of faba bean farming in the Southern Levant.

Even though the faba bean (Vicia faba L.) is among the most ubiquitously cultivated crops, very little is known about its origins. Here, we report discoveries of charred faba beans from three adjacent Neolithic sites in the lower Galilee region, in the southern Levant, that offer new insights into the early history of this species. Biometric measurements, radiocarbon dating and stable carbon isotope analyses of the archaeological remains, supported by experiments on modern material, date the earliest farming of this crop to ~10,200 cal BP. The large quantity of faba beans found in these adjacent sites indicates intensive production of faba beans in the region that can only have been achieved by planting non-dormant seeds. Selection of mutant-non-dormant stock suggests that the domestication of the crop occurred as early as the 11(th) millennium cal BP.

The plastered skulls from the Pre-Pottery Neolithic B site of Yiftahel (Israel)--a computed tomography-based analysis.

Three plastered skulls, dating to the Pre-Pottery Neolithic B, were found at the site of Yiftahel, in the Lower Galilee (Israel). The skulls underwent refitting and restoration processes, details of which are described herein. All three belong to adults, of which two appear to be males and one appears to be a female. Virtual cross-sections were studied and a density analysis of the plaster was performed using computed tomography scans. These were utilized to yield information regarding the modeling process. Similarities and differences between the Yiftahel and other plastered skulls from the Levant are examined. The possible role of skull plastering within a society undergoing a shift from a hunting-gathering way of life to a food producing strategy is discussed.
