The production technology of Egyptian blue and green frits from second millennium BC Egypt and Mesopotamia

The microstructures and chemical compositions of some 55 Egyptian blue and green frit samples from New Kingdom Egypt and 15th century BC Mesopotamia are determined using analytical scanning electron microscopy, the main focus being on frit cakes, powder residues, and frit vessel and bead fragments from one of the “factory areas” at Amarna in Middle Egypt. Replicate Egyptian blue frits produced in the laboratory are similarly investigated. Comparison of the microstructures of the ancient and replicate samples suggest that frit cakes are the primary product, and that these were ground to produce the powder, and then moulded to shape and refired to produce the vessels and beads. Egyptian blue and green frits are shown to be distinct pigments, the pigment produced depending on the relative proportions of copper oxide and lime in the mixtures. The bulk and glass phase compositions are used to try to infer the different sources of the quartz, lime, copper and alkali flux used in the production of frits from Egypt and Mesopotamia. An estimate is made of the scale of production of Egyptian blue frit in New Kingdom Egypt.     

Soil fertility and slope processes in the Western Cumberland Escarpment of Kentucky: influences on the development of horticulture in the Eastern Woodlands

The archaeological record of dry rockshelters in the Red River Valley of eastern Kentucky contains botanical remains of several weedy annual seed-bearing plants that point to the independent development of agriculture during the Late Archaic and Early Woodland Period. The objective of this study is to gather quantitative data through the chemical and physical analysis of soils collected within a valley transect to gain insights into landscape processes and soil fertility that may have played a role in the early development of plant domestication and the location of garden plots in relation to rock shelter sites in the upper Cumberland Plateau region of eastern Kentucky. Soils on upland benches formed in limestones have soil fertility values that are comparable to fertile floodplain soils. Upslope outcrops of calcareous bedrock are contributing basic cations to these bench soils. Additionally, in comparison to other landscape positions these upland soils have high levels of organic carbon, available P and greater C:N ratios. Soil morphology, radiocarbon dates, and archaeological evidence indicate that many of the numerous earthflows and debris flows within the region are Early to Middle Holocene in age. These slides were likely generated by Mid-Holocene climatic shifts in which the frequency and intensity of summer precipitation increased across the southeastern United States. These slope failures may have contributed to the development of plant domestication by creating forest canopy gaps and disturbed soils in which weedy plants thrived.     

Archaeology and the Forensic Investigation of Recent Mass Graves: Ethical Issues for a New Practice of Archaeology

The close of World War II marked the advent of international human rights legislation and the prosecution of individuals for human rights crimes, by both nation states and international tribunals. The prosecution at such trials often presents evidence from forensically excavated mass graves. Forensic archaeology is a new and expanding field and as such has yet to establish a uniform code of ethics, standard operating procedures, and transparency. In addition, there are complex and conflicting agendas of mass grave excavation. Mass grave investigation in Iraq since the 2003 American-led invasion is presented as a case in point.

Résumé  La fin de la seconde guerre mondiale a marqué l’avènement international de la poursuite judiciaire des individus ayant commis des crimes de guerre et d’une législation des droits de l’homme à la fois de la part des nations et des tribunaux internationaux. La poursuite judiciaire engagée à souvent fourni la preuve de la présence, par excavation, de tombes de masse. L’archéologie des expertises médico-légales est devenue un champ nouveau en pleine expansion, et, en tant que tel, a établi un code éthique généralisé, ainsi que des procédures standard et de transparence. De plus, il existe des agendas complexes et conflictuels de tombes de masse découvertes par excavation. Ceci s’applique à l’Irak depuis 2003 où l’invasion menée par les. américains est sujette à enquête.

Resumen  El fin de la Segunda Guerra Mundial marcó la aparición de una legislación internacional de derechos humanos y los juicios contra los acusados de crímenes contra los derechos humanos, tanto por parte de los estados nacionales como los tribunales internacionales. En los procesos de estos juicios a menudo se presentaban pruebas de la existencia de fosas comunes excavadas por forenses. La arqueología forense es una nueva disciplina en crecimiento y por ello, aún no ha establecido un código ético uniforme, procesos de funcionamiento estándar ni transparencia. Asimismo, hay programas complejos y conflictivos de excavación en fosa comunes. La investigación de fosas comunes en Irak desde la invasión del 2003 encabezada por EE.UU. se presenta como un caso paradigmático.

     

应用热裂解气相色谱质谱技术对六种蛋白质类胶结材料的分析与鉴别

利用在线甲基化水解-裂解气相色谱质谱(THM-Py-GC/MS)技术对古代壁画、彩绘等文物中常用的骨胶、皮胶、鱼鳔胶、蛋清、蛋黄和猪血等六种蛋白质类胶结材料进行分析,采用盖蒂保护研究所开发的RAdICAL系统对谱图进行解析,总结了每类材料的特征裂解产物。研究表明,吡咯类化合物,特别是吡咯、二吡咯二酮和哌嗪二酮类化合物可以作为骨胶和皮胶的识别组分,鱼鳔胶的识别组分除了上述吡咯类化合物之外,还包括胆固醇类化合物。吲哚类、血/蛋清标记物、磷酸三甲酯、脯氨酸类化合物是蛋清的识别组分。除了含有蛋清的4种识别成分之外,猪血的识别成分还包括胆固醇类化合物。蛋黄的识别组分是磷酸三甲酯、蛋黄标记物和胆固醇类化合物。最后利用主成分分析法(PCA)对福建省泉州市安海县龙山寺千手观音佛像上脱落的膜状残片的数据和六种蛋白质类胶结材料的数据进行解读,确定了膜状残片的蛋白质类有机材料为动物胶(骨胶或皮胶)和蛋清,证明PCA是一种有效的降维和可视化方法。本研究利用PCA技术对THM-Py-GC/MS数据进行分析解读,且结果可信,为之后该技术的发展提供新的契机。

Silver production at al‐Radrad: archaeometallurgical analysis of ore,slag and technical ceramics from early medieval Yemen

The zinc‐lead‐silver deposit of al‐Jabali, about 65 km north‐east of Sana'a in Yemen, has been identified as the location of the late antique/Islamic period silver mine al‐Radrad. Exploitation of the mine is known from the account of al‐Hamdani, an Arab geographer of the tenth century AD. The al‐Jabali area has been the focus of geological and archaeometallurgical surveys, and extensive metallurgical remains have been discovered. Samples of ore, slag and technical ceramics were collected for archaeometallurgical analysis. The technology of silver production is discussed in relation to the historical record, and elemental and lead isotope characterisation of ore and slag provides a basis for future provenance studies.     

The Social and Economic Complexity of Ancient Jerusalem as Seen Through Choices in Lighting Oils

This paper presents and discusses the results of residue analysis conducted on 78 ceramic lamps found in archaeological excavations in ancient Jerusalem, in an attempt to identify the types of oils used and the reasons for their preferential choice. The oil lamps chosen for the study were taken from a variety of contexts, which represent the different periods during which Jerusalem was settled and the different sectors of the city. The results of the study show that even the most mundane activity of lighting using oil held within it social and economic choices, as mirrored in the different excavation areas.     

Anarchy,Geography and Drift

Abstract: The consumerist economies of the late modern city, in combination with contemporary models of urban policing, operate to close down the public spaces of social life. In response, social groups dedicated to democratic urbanism utilize anarchic tactics of “dis‐organization” and direct action to reopen public space and to revitalize it with unregulated activity. Complicating and animating these spatial conflicts is the issue of drift. On the one hand, consumerist economies and contemporary policing strategies exacerbate urban drift, spawning the very sorts of spatial transgression they seek to control. On the other hand, many of the progressive movements that battle for open space and alternative economic arrangements themselves embrace a culture of drift, and explore drift for its anarchic and progressive potential. In this context drift can usefully be investigated as an emergent form of epistemology, community, and spatial politics.     

Microstructural,chemical and isotopic evidence for the origin of late neolithic leather recovered from an ice field in the Swiss Alps

Archaeological leather samples recovered from the ice field at the Schnidejoch Pass (altitude 2756 m amsl) in the western Swiss Alps were studied using optical, chemical molecular and isotopic (δ¹³C and δ¹⁵N of the bulk leather, and compound-specific δ¹³C analyses of the organic-solvent extracted fatty acids) methods to obtain insight into the origin of the leather and ancient tanning procedures. For comparison, leathers from modern native animals in alpine environment (red deer, goat, sheep, chamois, and calf/cow) were analyzed using the same approach. Optical and electron microscopically comparisons of Schnidejoch and modern leathers showed that the gross structure (pattern of collagen fibrils and intra-fibrils material) of archaeological leather had survived essentially intact for five millennia. The SEM studies of the hairs from the most important archaeological find, a Neolithic leather legging, show a wave structure of the hair cuticle, which is a diagnostic feature for goatskins. The variations of the bulk δ¹³C and δ¹⁵N values, and δ¹³C values of the main fatty acids are within the range expected for pre-industrial temperate C₃ environment. The archaeological leather samples contain a mixture of indigenous (from the animal) and exogenous plant/animal lipids. An important amount of waxy n-alkanes, n-alkan-1-ols and phytosterols (β-sitosterol, sitostanol) in all samples, and abundant biomarker of conifers (nonacosan-10-ol) in the legging leathers clearly indicate that the Neolithic people were active in a subalpine coniferous forest, and that they used an aqueous extract of diverse plant material for tanning leather.
