Seven fragments of atypical proto-majolica from the archaeological site of Siponto (Manfredonia, Foggia) were analysed by chemical and physical methods. All fragments have blue, brown and yellow painted decorations. Raman microscopy and Scanning Electron Microscopy–Energy Dispersed Spectroscopy (SEM–EDS) investigations identified the blue pigment to lapis lazuli. We previously identified this mineral in the blue coloration of the tin–lead glaze of proto-majolica finds at other Medieval sites in Apulia (Castel Fiorentino and Lucera). The discovery of the fragments from Siponto, in spite of their peculiar technological-decorative features, proves that the use of lapis lazuli as a ceramic pigment was not an isolated occurrence, but was quite common in the Middle Ages in the production of typologically heterogeneous ceramics in Southern Italy.  相似文献

为了解青海民和回族土族自治县(以下简称民和县)阳山墓地(半山类型)和马牌墓地(马厂类型)出土的马家窑文化彩陶颜料成分及制作工艺,采用偏光显微技术、显微拉曼光谱、X射线衍射及扫描电镜-能谱对其进行综合分析。结果表明:民和县马家窑文化彩陶黑彩的呈色物相为磁铁矿和黑锰矿;红彩的呈色物相为赤铁矿;白彩的呈色物相为石英;黑彩的Fe/Mn比值,从半山时期的0.31增长到马厂时期的2.45左右,Fe/Mn比值呈现上升趋势。民和县铁矿颜料的应用是继化隆县纳卡遗址发现的又一实例,为研究矿物颜料在甘青地区史前时期彩陶中的使用历史提供重要的线索。结合地质文献资料,推测青海民和县所使用的矿物颜料为就近取材。陶胎岩相主要由石英、长石、角闪石及碳酸钙组成;以强烈铁染为特征;孔隙较多,大多拉长定向分布;在900℃左右焙烧成器。在此基础上将对甘肃和青海地区史前彩陶岩相组成进行对比研究,深入探析彩陶贸易及陶器产地信息,进而为陶器的研究与保护提供依据。  相似文献

The 67-ha site of Sincu Bara was discovered and extensively excavated in the 1970s. Three primary aspects of its archaeological interest were its vast size, its location in the Middle Senegal Valley, where some of the earliest regional polities in West Africa arose, and the extensive and diverse assortment of copper-based metal artifacts it produced. Deposits with brass appeared to be associated with radiocarbon dates as early as the fifth century AD. It appeared that most of the deposits related to a single, long-lasting occupation by people who arrived with sophisticated copper-based metallurgy in the fifth century and remained at least until the eleventh century, without discernible modification in their material culture. Results of new excavations in 1991–1992 indicate that this interpretation must be substantially modified, since considerable change in material culture, including the introduction of copper-based metals between AD 800 and AD 900, has now been documented. This article summarizes the data from these new excavations and suggests that earlier interpretations were based largely on material from disturbed, severely mixed deposits, which gave a false picture of homogeneity through time.Les soixante sept héctares constituant le gisement du Sincu Bara étaient découverts et fouillés dans les années soixante dix. Son intérêt archéologique est lié aux trois aspects: sa grande superficie, sa location dans la vallée moyenne du Sénégal où les premières unités politiques de l'Afrique de l'Ouest existaient, et finalement, la diversité des objets métalliques en cuivre que le site a livrée. Il apparaît que la plupart des dépôts appartient à une seule occupation de longue durée par un peuple qui est arrivé pendant la cinquième siécle AD, en possession de la connaissance de métallurgie à base de cuivre et qui montrait au moins jusqu'au onzième siécle peu de modification dans leur culture materielle. Les résultats des fouilles de 1991–1992 montrent que cette interpretation doit être modifiée, car il y a eu du changement considérable dans le matèriel, comme l'introduction des métaux à base de cuivre entre AD 800–900. Dans cet article, nous avons résumé les résultats des nouvelles fouilles et nous suggérons que les anciennes interpretations ont été largement fondées sur du matériel perturbé, des dépôts mixtes qui donnaient une image fausse de l'homogenité pendant cette période.  相似文献

唐代“投匦奏事”制度初探   总被引:1,自引:0,他引:1  
“投匦奏事”制度是唐代监察制度的重要补充形式之一。“投匦奏事”始于唐武则天垂拱年间,从此,作为一种制度一直沿用到唐末。考察唐匦的沿革、匦使院知匦使、理匦使的设置及其职责、对投匦人及其奏事方式的规定和要求,无疑将有助于我们对唐代监察制度的进一步了解和认识。  相似文献

The recent literature on ceramic analysis, which has grown dramatically over the last 8 years, is reviewed in two articles. In this first article attention focuses on studies of function and use, stylistic analyses, and pottery origins. Functional analysis has been the most rapidly expanding segment of the field, particularly experimental, ethnoarchaeological, and residue analysis approaches. Stylistic analyses seem to be in a lull, following increasing dissatisfaction with information theory approaches. Questions of pottery origins are enjoying renewed interest and are briefly surveyed here. The second of the two articles will survey compositional investigations, pottery production, and approaches to ceramic theory. Both reviews close with observations on current directions in ceramic studies.  相似文献

The East African Neolithic has been attributed to the migration of food- producing populations from the Sudan and Ethiopia. The migrants are thought to have entered the region via northern Kenya. Attempts have been made not only to reconstruct the routes taken by those migrants, but also to establish their linguistic and/or ethnic identity. These attempts have treated Neolithic pottery wares as discrete cultural entities and correlated them with specific linguistic and/or ethnic groups. The main problem with this approach is that it minimizes the contribution that contact and exchange or trade may have made to culture change. It also denies the groups concerned the dynamism that appears to have characterized their relationships with each other and with their environment. The present paper offers an alternative interpretation of the Neolithic phenomenon. The similarities and differences in material culture, like the ones that have been used to define the pottery wares in question, are reflections of the dynamic relationships that existed between the people responsible for its production and consumption. Production and consumption of the wares could have taken place among individuals living in a given area or among different villages or communities living as far apart as the Central Rift and the Lake Victoria basin.
Résumé Le néolithique de l'Est de l'Afrique a été attribué à des migrations de populations productrices de nourriture en provenance du Soudan et d'Ethiopie. On pense que ces migrations ont pénétré dans la région via le Nord du Kenya. Des tentatives ont été faites, non seulement pour reconstruire les routes empruntées par ces migrants, mais aussi pour établier leur identité linguistique et/ou ethnique. Ces tentatives ont utilisé les différents groupes de poterie néolithiques comme autant d'entités culturelles discrètes et les ont mises en relation avec des groupes linguistiques ou ethniques spécifiques. Le problème principal avec cette approche est qu'elle minimise la contribution que les contacts, les échanges ou le commerce ont pu avoid sur le changement culturel. Elle ne prend pas non plus en compte le dynamisme qui semble avoir caractérisé leurs relations entre elles et avec leur environnement. Le présent article tente d'offrir une interprétation alternative au phénomène néolithique. Ceci est réalisé en utilisant un modèle interprétatif que reconnaît que les humains ont des capacitiés intellectuelles et technologiques multiples et que les décisions et actions individuelles sont reflétées par les restes matériels des sociétés auxquels appartiennent les individus. Par conséquent, les similarités et les différences dans la culture matérielle comme celles qui ont été utilisées pour définir les groupes de poterie dont il est question sont le reflect de relations dynamiques qui existaient entre les peuples responsables de sa production et de sa consommation. La production et la consommation de ces groupes peuvent s'êtres produites parmi des individus vivant dans une région donnée ou parmi différents villages ou communautés vivant aussi éloignées l'une de l'autre que le Rift Central et le bassin du Lac Victoria.

This paper reports the results of excavation at Mugharat al-Kahf (WTN01) in Wādī Tanūf, North-central Oman. It also provides information on the nonmortuary and nonsedentary activities in central Oman during the Wādī Sūq period (2000–1600 BCE), as the subsistence and social arrangements of this period are the subject of much debate. Previous surveys had discovered a substantial amount of Wādī Sūq pottery at the site. This project took forward the excavation for further exploration. The excavation at Test Pit 1 identified Layers Ia and Ib, wherein pottery sherds, charred date stones and other samples for radiocarbon dating were discovered. These prove the cave's occupation during the early third millennium BCE, early second millennium BCE and the Islamic period. The analysis of artefacts and floral remains provided insights into the sojourn, storage and consumption of dates in the cave, and the mobile lifestyle in central Oman.  相似文献

For the first time, the mineralogical–geochemical compositions of the white paste inlay found on vessels from sites (10th–8th centuries bce ) in the northern Pontic region are investigated. Samples of the white paste on vessels from settlements, burials of sedentary groups and graves of early nomads were analysed by means of scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDX) and X-ray diffraction (XRD) methods. Between the 10th and eighth centuries bce , various innovations occurred in the working area. Iron processing technology and the manufacture of iron products also appeared. Other innovations were changes in the manufacturing technology of ceramics. A high-quality, polished/burnished surface and ornaments with white paste inlay are characteristic of this pottery. When collating white paste mixtures of different European sites, similarities in the preparation of white paste recipes for vessels from the Balkan and northern Pontic regions are evident. During the Early Iron Age, further changes in the manufacture of the white paste were discovered in the northern Pontic region, namely the application of high-temperature firing to obtain more resistant synthesized material such as calcium alumosilicates and silicates (wollastonite). The development of iron metallurgy in this period could provide a basis for the elaboration of new techniques in ceramic manufacture.  相似文献

The paper focuses on ceramic vessels unearthed from Copper Age necropolises located in the area of the modern city of Rome and commonly attributed to the Rinaldone culture. The peculiar vessels' shapes, mainly associated with the consumption of beverages, their accuracy of manufacture and the very low impact of these ceramic morphologies in the coeval household assemblages lead to the study of such an apparently selected production through a multidisciplinary research. Petrographic analysis, X-ray fluorescence (XRF) and X-ray diffraction (XRD) integrated with the analysis of manufacturing traces and X-ray investigation suggest the transmission of technological choices, which remained unchanged over almost two millennia.  相似文献

The following study sheds new light on the quality control procedures of ancient potters by comparing cooking vessels exported from the medieval kiln‐site of Cabrera d'Anoia (Barcelona) with ‘wasters' that were discarded at source. The firing temperature of examined sherds indicates that only pots subjected to a maximum temperature of 800–850°C were offered for sale. The potters at Cabrera d'Anoia appear to have been fully aware of the optimal balance between thermal and physical shock resistance of vessels fired within this range and strived to control firing in order to achieve better products than that of competing workshops.  相似文献
