The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes.  相似文献

Within the making of Portuguese liberal‐representative democracy, the Portuguese Communist Party became a major actor in local government in urban deprived peripheries, shaping Lisbon's Red Belt. In this article, we analyse the communist discourse on the Portuguese urban question, showing how it politicised the urban as a site of unevenness and deprivation, but simultaneously depoliticised it by refusing to acknowledge it as a proper space for conflict. This historical account leads us to a critical debate with proposals that discuss urban politicisation by ontologising “the urban” or “the political”—we argue that these approaches tend to be less helpful in understanding processes of contingent, partial and inter‐related forms of politicisation/depoliticisation of the urban in itself. In contrast, we argue for a more attentive theorisation on politicisation–depoliticisation of the urban condition as a most valuable path to grasp situated formulations of citizenship and, hence, configurations of political regimes.  相似文献

尉氏元代壁画墓札记   总被引:1,自引:0,他引:1  
尉氏县张氏镇壁画墓在最近的报道中被断为宋代。本文结合相关考古资料,从墓葬形制、壁画布局、仿木结构、人物服饰、墓门题记等几个方面进行对比分析,将该墓订正为元代。又依据文献记载和图像资料,对该墓壁画中“曾参行孝”和“焦花女哭麦”两组孝子图加以考证。并进一步梳理了考古所见二十四孝图像,发现其组合形式在宋金时期比较稳定,而元明时期则逐渐转向多元。  相似文献

顺治九年(1652),一艘赴日本贸易的苏州商船回国。史学界对该商船的赴日时间及贸易方式存在争议:一说是1644年赴日,在日本进行了八年的海外贸易;一说是1650年或1651年私自出海,交易完毕后即回国。本文根据明清档案及朝鲜史料对该事件的记载,以及当时中国、东南亚、日本之间的贸易状况进行综合考察,可以肯定该商船是于1644年前往日本,并在日本与交趾之间从事贸易活动。  相似文献

Metallurgical study of seven cast iron artifacts recovered from sites of the former Xiongnu (BC 3rd to AD 1st), Turk (AD 6th to 8th), Khitan (AD 10th to 12th), and Mongolian empires (AD 12th to 15th) shows that the earlier Xiongnu and Turk artifacts were made of cast iron alloys of near eutectic composition. The later Khitan and Mongol objects had greatly reduced carbon content in the range of ultrahigh carbon steel rather than cast iron, and contained more than 0.5 mass % silicon as an alloying element. Inclusions high in sulfur, phosphorus or silicon are also present. These differences suggest that Mongolia experienced a technical transition a few centuries before the establishment of the Mongolian empire, which is in agreement with some written accounts. The microstructures of the cast iron artifacts are compared with the related archaeological and documentary evidence. The results suggest that the use of fossil coal in smelting and the state policy of controlling iron production were the major factors responsible for the transition.  相似文献

Scanning electron microscopy/energy dispersive X-ray analysis has earlier shown that the white background layer (slip) on painted pottery sherds (Yangshao culture, Henan, China, 4200 BC) is composed of kaolinitic clay containing titanium in the assumed form of TiO2 at just 1 wt%. The same samples of white slip have now been studied by Raman microscopy, revealing bands characteristic of anatase, but none from the majority species, the matrix of kaolinitic clay. These results highlight the extraordinarily intense Raman scattering from even trace amounts of anatase and thus the need to recognise that, although the colours of archaeological artefacts are almost always determined by the nature of the matrix, the Raman spectrum may be determined by a highly scattering trace component such as anatase. The significance of anatase as a potential date-marker pigment on works of art and archaeological artefacts is discussed.  相似文献

In luminescence dating, the potassium concentration significantly contributes to the dose rate value in the age estimation. Within this study, fine-grain thermoluminescence dating has been applied on sherds of calcareous pottery of known age, excavated at a Roman site in Mallorca, Spain. For those of the samples that showed signs of severe potassium leaching, according to chemical and mineralogical examination, the thermoluminescence analysis provided overestimated dates. By using the known archaeological age of the samples, a corrected dose rate value can be estimated which provides the potassium concentration averaged for the burial period. Finally, a step-like model can then be used to estimate the fraction of the burial period after which most of the alteration effects took place.  相似文献

雷戈所著《秦汉之际的政治思想与皇权主义》一书,认为从秦朝到汉初的思想史发展阶段是中国思想史上皇权主义意识形态的生成和确立时期,并将其概括为"后战国时代";采用独特的"历史-思想"研究法,从政治制度、官场规则和官吏的政治生活中,挖掘特定时期的政治思想共识,为政治思想史研究开辟了新的路径,并扩大了思想史的资料范围;认为秦汉时期生成的皇权主义秩序,把"天高皇帝远"的制度现实变为"天高皇帝近"的观念实存,实现了对人们思想的可控性,从此,思想成为皇权可以控制和规范的领域,达到了有效的思想专制。这是秦汉以降中国思想史发展的基本特征。该书在研究方法的创新和思想深度的开掘上,都做出了独到的贡献。  相似文献

何塞.黎萨尔被认为是菲律宾"国家和个人生活的基石"。在有关黎萨尔的研究中,黎萨尔与菲律宾政治变革的途径,即经由"改革"还是"革命"来达致国家的独立、获取全民的"福利",是争论不休的一个关键问题。从黎萨尔的著作来看,黎萨尔倾向于经由菲律宾政治精英在殖民政府内部对现有不合理的旧制度进行一场彻底的、激进的"好改革"来实现菲律宾的独立和民主。如果这一条道路走不通,那么,"暴力革命"将是最后的手段。黎萨尔所强调的"精英化的好改革"的政治思想,经由美国殖民政府的渲染,最终构成为菲律宾现代政治变革的基本模式——旧框架内的和平革命。  相似文献
