We have determined the composition of rock art pigments from two megalithic barrows located in the north of Portugal. The use of XRD, SEM–EDS and FT–IR spectroscopy confirmed the presence of hematite and kaolinite in the red pigments from the Eireira barrow, and kaolinite in the white pigment from the Leira das Mamas barrow. The organic composition of the pigments was studied by GC–MS, suggesting that the red sinuous lines and dots from the Eireira barrow were prepared with cooked or heated algae and/or aquatic plants, with egg as binder, while the white pigment from the Leira das Mamas barrow revealed a mixture of vegetable oils for kaolinite moulding, which could be stabilized by temporary exposure to high temperatures. The multi‐analytical approach used on this study of megalithic pigments allowed the recovery of important data about north‐western prehistoric communities, namely the way in which they exploited existing resources and their ability to transform them.  相似文献

Fifty‐seven glass samples from Carthage dating to the fourth to sixth century ad were analysed using the electron microprobe. The results show that these samples are all soda–lime–silica glass. Their MgO and K2O values, which are below 1.5%, suggest that they were made from natron, a flux that was widely used during the Roman period. The major and minor elements show that these samples can be divided into four groups, three of which correspond to the late Roman period glass groups that were found throughout the Roman Empire: Levantine I, and ‘weak’ and ‘strong’ HIMT. Of particular interest is our Group 2, which is technologically and compositionally similar to HIMT glass and the CaO and Al2O3 values of which are similar to those of Levantine I. Glass of similar composition has been reported by several authors and is predominantly found dating from the late fifth to seventh century. This could represent a ‘new’ glass group; therefore further study is needed to determine its origin. Also, this study suggests that the Vandal invasion in North Africa did not disrupt the glass trade between Carthage and the Levantine coast.  相似文献

In September 2014, the University of New England (UNE), Australia, began a three‐year programme of archaeological fieldwork and post‐excavation analyses focused on the site of Saruq al‐Hadid. In this paper, we present the initial results of our current field and laboratory research particularly related to site stratigraphy and formation processes, relative and absolute chronology, and the preliminary results of various programmes of post‐excavation analyses including archaeobotanical, zooarchaeological, ceramic and archaeometallurgical studies. These studies provide new data to build into the archaeological understanding of Saruq al‐Hadid that has, to date, focused largely on intensive excavation.  相似文献

Urban and Rural Definitions in Regional Context: A Case Study on Turkey   总被引:2,自引:0,他引:2  
Transformations in the urban and rural areas under the effects of global economic, social and political circumstances have rendered their boundaries more blurring. It has become increasingly difficult to make a clear distinction between urban and rural. This paper intends to bring definitions of urban–rural into discussion in the context of Turkey. It reveals the results of a research project (conducted by Hürriyet G. Ö?dül with Serkan Öngel and Habip Uluçay from Mimar Sinan Fine Arts University, Istanbul, Turkey, in 2007 and financed by the Scientific and Technical Research Council of Turkey and Mimar Sinan Fine Arts University Research Fund), aiming at revealing the degrees of the urbanity and rurality throughout the country, with an emphasis on the diversification of regions in the urban–rural context. The study is conducted at the NUTS 4 level. Districts are classified as “dominantly rural, dominantly urban and transitional” through the factor analysis based on six structures: agricultural production, non-agricultural production, employment, demography, education and flows of money, goods and people. The urban–rural profile of the country is found as rural and transitional. It is possible to observe some areas displaying deep rural characters in well-developed western regions and some “prosperity spots” dispersed throughout the less-developed eastern regions. Then, regional classifications ranging from “concentrated urban regions” to “rural regions” are made at the NUTS 1 level. Finally, the results are evaluated in perspectives of spatial planning of Turkey and entering process to the EU.  相似文献

More than fifty years after the discovery of the first remains from Pozo Moro, new research has begun to question the arrangement, until now agreed upon, of the tower-shaped monument. The recent paper by García Cardiel and Olmos (2021) employs iconography to sketch the possibility that the reliefs and sculptures encountered in said necropolis do not belong to a single monument, but two or more. In this paper we delve into this possibility by studying a fragment of architectural moulding from Pozo Moro, which allows us to conclude the possible existence of a pillar-stele datable between 425–300 BC, when the necropolis was at its floruit. To reach this conclusion special attention is paid to Iberian architectural ornaments, a subject seldom yet studied.  相似文献

In the early 1960s the grave of a probable donor was discovered in the St Veit church in Unterregenbach, Stadt Langenburg, Kreis Crailsheim, southwestern Germany. After a re-examination, the skeleton may be regarded as clearly corresponding to the typical clinical picture of a multiple myeloma/plasma cell myeloma. The 45–55-year-old female individual shows all the characteristics of a malignant plasma cell tumour, with specific osteolytic lesions of the skull, vertebrae, ribs, pelvis, scapulae and long bones, and even-sized single defects without reactive zones on the edges. Several pathological fractures of the ribs and a vertebral compression fracture can be observed. The gnawing-mark-like features on the inner surface of the compact bone and the ‘punched-out’ lesions on the outer are distinguishing marks of a multiple myeloma.  相似文献
