This paper presents a detailed elemental analysis of 64 glass beads and pendants dated to the Meroitic period (first–third centuries ad ) and the Nobadian period (fourth–sixth centuries) from burial sites in the Lower Nubian Nile Valley region. Laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) was used to determine the chemical composition of the glass and to gain knowledge about its origin. Four main glass types were identified: low‐alumina soda‐lime glass, high‐alumina glass, plant‐ash soda‐lime glass, and mixed‐alkali glass. Mineral soda‐lime glass (m‐Na‐Ca) of East Mediterranean/Egyptian provenance is dominant within the low‐alumina glass group from Meroitic and Nobadian periods. Mineral soda high‐alumina glass (m‐Na‐Al) appeared in the Nobadian bead assemblages, and the m‐Na‐Al 1 subtype was produced in Sri Lanka/South India. An initial insight into the origin of the glass beads in Nubia from the first to sixth centuries is described, indicating the first evidence for the presence of Asian objects in Nubia. The data obtained for the bead trade in North‐east Africa in this study has allowed a new light to be shed on the westward flow of Asian glass during a time of intensive maritime trade contacts with the wider Indian Ocean world. 相似文献

Tree‐ring dating involves matching sequences of ring widths from undated timbers to dated sequences known as ‘master’ chronologies. Conventionally, the undated timbers (from a building or woodland) are sequentially matched against one another, using t‐tests to identify the relative offsets with the ‘best’ match, thus producing a ’site’ chronology. A date estimate is obtained when this is matched to a local master chronology of known calendar age. Many tree‐ring sequences in the UK produce rather low t‐values and are thus declared not to have a ‘best’ match to a master chronology. Motivated by this and the routine use of Bayesian statistical methods to provide a probabilistic approach to radiocarbon dating, this paper investigates the practicality of Bayesian dendrochronology. We explore a previously published model for the relationship between ring widths and the underlying climatic signal, implementing it within the Bayesian framework via a simulation‐based approach. Probabilities for a match at each offset are produced, removing the need to identify a single ‘best’ match. The Bayesian model proves successful at matching in both simulated and real examples. 相似文献

Tinning copper and copper alloy objects by putting them into (electrical) contact with metallic tin in a boiling aqueous solution of potassium hydrogen tartar is a very old technique, but is nowadays almost forgotten. It was possibly invented by the Gauls and used intensively until the 20th century. This paper first briefly recounts the history of this galvanic process. To understand better the parameters influencing the thickness of the coat and thus to reconstruct this ancient technique, laboratory tests were undertaken by varying a series of parameters. The results are then presented with a short interpretation. 相似文献

Xuxiebian is an iron‐smelting site located in Pujiang county of Sichuan province, China. Two excavations were carried out in 2007 and 2011, and four bowl‐shaped furnaces were excavated. Ten slag samples from the site were prepared and analysed. The present paper reports the results of metallographic and elemental examination of the specimens. It is concluded that both pig‐iron‐smelting and refining process were applied at the Xuxiebian site, and the bowl‐shaped furnaces are possibly refining furnaces. The function of the site was probably to produce pig iron and refine the pig iron into wrought iron. 相似文献

During the Late Holocene, important changes can be identified in the social dynamics of hunter‐gatherer populations in different regions of the Southern Andes. These transformations are associated with processes of demographic growth, territoriality, increased social complexity, technological innovations, and intensified exploitation of the environment. One of the technological transformations associated with these processes is the popularization of bone instruments. In this study, we discuss the functions of bone tools made by Late Holocene coastal hunters‐gatherers of North‐Central Chile, by carrying out a morphological characterization and identifying use‐wear patterns on their surfaces. Our results show that bone technology was used for hunting, fishing, and gathering activities, from flint working to processing vegetal fibres and hide. A reduce number of artefacts had an ornamental use as well. These results suggest a varied and intensive exploitation of the surrounding space by coastal groups, where bones of land animals constituted an important part of the raw materials used in bone industry. Also, we argue that some bone artefacts were elements structuring social relations, as they participated in flows of information and social networks. We conclude by arguing that the popularization of bone industry reflects the dynamics of social complexity, as well as how bone was integrated as a productive, economic, and social resource in the process of coastal hunters and gatherers who inhabited the area. 相似文献

The main aim of this study is to present a novel method of nonadult (ca. 1–19 years) age‐at‐death estimation using the dental wear of deciduous, mixed deciduous‐permanent, and permanent dentitions, including the incisors, canines, premolars, and first and second molars. The stage‐based method is derived from degrees of dental wear in known‐age (n = 39) and estimated‐age (n = 11) nonadults containing 951 teeth from the predominately 19th century cemetery of Middenbeemster, The Netherlands. The need for such a method is warranted in cases where dental development and/or eruption cannot be assessed for age‐at‐death estimation. As well, by establishing a baseline for normal age‐related nonadult tooth wear, users may better document wear that could be due to extramasticatory behaviours. The regression analysis reveals a strong quadratic correlation—F(2, 47) = 555.1, p < .001, R2 = .95, standard error of the estimate = 1.14, residual sum of squares (RSS) = 68.89, predicted residual error sum of squares (PRESS) = 77.67—between age and wear and multivariate adaptive regression splines (R2 = .95, generalised cross validation = 1.67, RSS = 67.68, PRESS = 89.34), which are used to develop an R‐package that users may employ to estimate age‐at‐death from dental wear. The accuracy of this method (78–98%) is evaluated using leave‐one‐out cross‐validation. Analyses of males versus females, deciduous versus permanent, upper versus lower, and anterior versus posterior teeth revealed no apparent reason to warrant separate methods for these groups of separated dentitions. This method fills a disciplinary gap in the understudied area of deciduous and nonadult dental wear and hopes to stimulate much future research. With the R‐package, we also provide the foundation and framework for the development of additional reference populations across different spatiotemporal contexts, to make the method more widely applicable. 相似文献

Shahr‐i Sokhta (Iran) was an important urban settlement in the Near East between the end of the fourth millennium and the beginning of the second millennium BC. It entertained trade and cultural relations with ancient sites and cultures on the Indus Plain, southern shores of the Persian Gulf and of the Oman Sea, Southwest Iran, and Central Asia. The recent discovery of a rhesus macaque (Macaca mulatta) burial in the cemetery of site shed new light on the exploitation of monkeys in antiquity. A young rhesus macaque—around 5 years old at death—was buried in the necropolis according to the same funerary practices used for human infants. The monkey was buried in a simple pit, together with an unpainted pear‐shaped beaker. Both its femurs were pathological, due to a sort of dystrophic calcification of the tendon or muscle insertion, that may suggest the macaque was kept in captivity and died due to physical stress. No non‐human primate species is native of Iran; rhesus macaques inhabit parts of southern and south‐eastern regions of Central Asia. A possible provenance from the Indus valley of the macaque found at Shahr‐i Sokhta can be hypothesized. Although findings of monkey remains are rare, iconographic and written sources widely testify that non‐human primates were imported to the Near East in the fourth‐to‐second millennium BC as luxury animals and symbols of power, often as gifts for the elite. This discovery represents one of the earliest examples of monkeys being kept as pets. 相似文献

Multiple myeloma (MM) is of special interest in anthropology, in particular in the differential diagnosis with metastatic carcinoma. In this paper, we present two cases of known MM and discuss the criteria for diagnosis in comparison with the literature. Two skeletons from the identified CAL Milano Cemetery Skeletal Collection were selected for the antemortem clinical diagnosis of MM in their associated medical data. Each lesion observed during the anthropological analysis was reported and considered. Lesions were observed in both cases in the pelvis, sacrum, ribs, vertebrae, scapulae, proximal ends of femora and humeri as well as in the skull. Moreover, they presented similar morphological traits. Consequently, lesions in MM are multifocal, round, lytic, sharply demarcated, relatively uniformly small, and specifically located in highly vascularized areas of the skeleton. These results are consistent with data from the literature and strengthen the criteria for diagnosis of the condition. 相似文献

This study explores the age at death structure, skeletal lesions, and artificial cranial modification (ACM) on 35 nonadults until their 38 months of life recovered from the Tarapacá 40 cemetery, Northern Chile. Age estimations were based primarily on long bones dimensions, whereas skeletal lesions and ACM were recognized on dry bones and in mummified and bundled bodies. Measurements and observations in these later were performed by radiographies. Results show a distribution of ages at death clustered in three groups: around birth and second month of life, between 9 and 12 months of life, and between 18 and 26 months of life. The presence of physiological disruption indicators such as porotic hyperostosis, cribra orbitalia, criba femoris, periostitis and Harris lines, and ACM is described. Then, we discussed the observed age at death structure and the skeletal lesions as reflecting weaning process, and the links between the nature and timing of this practice with social organization of care labour, control over female sexuality, and socio‐economic transformations occurring during the Formative Period in Northern Chile. 相似文献

The African continent is known by various metaphors and geographies, but for many there are also unknowns about the continent. Geopolitically, Africa is a continent that is considered remote—an economically emerging continent seen as entangled in persistent challenges of wars, political dictatorship, poverty, disease, and more recently migration. Given these predispositions it is typical to stereotype events, practice, and behaviour as “African.” There is, however, now recognition of the continent as emerging economic power house. But unpacking the diversity of Africa reveals a huge potential with respect to resource endowments, diversity of ecology, socio‐cultural economic advancement, politics, language, and demographics. Colonial history coupled with traditional Africa shaped the geopolitical boundaries that have added to the confusion about this massive and diverse continent. Intellectual discourses either amplify the differences due to specificities of geographical focus or generalizations such as the contested notion of “African.” However, using socio‐ecological lenses, Africa is unified by these very differences in addition to being a massive landmass with several big and small island states. Appreciating these differences is useful to understanding the observed patterns of social, economic, and political systems that unify the continent. This paper illustrates the notion of “African” to describe the heterogeneous nature of a “unified” continent. Some illustrative examples between Africa and other continents are used. 相似文献
