The Emerald site, also known as the Emerald Acropolis, was an early Mississippian pilgrimage center key to Cahokia’s development. This paper presents the hitherto unpublished results of two archaeological projects conducted at the site, one led by Howard Winters and Stuart Struever in 1961 and the other by Robert Hall in 1964. These investigations produced the most comprehensive information on Emerald’s Moorehead phase (1200–1300 CE) occupation, during which two of its mounds were capped, a secondary mound was constructed on the central mound, and a mound-top structure was erected on this secondary mound. Similar activities took place throughout the region during the thirteenth century, a time marked by dramatic social, political, and religious change in Greater Cahokia. Based on these data, we argue that people returned to Emerald to memorialize or draw on the powers inherent there and thus reincorporate this place into the newly imagined thirteenth century Cahokian world.  相似文献

ABSTRACT

Instead of the framework of influence–acceptance commonly used in previous studies, the author uses new sources to reexamine John Dewey’s visit to China from the perspective of interactive experience. This study presents Dewey’s lectures in China as the result of interrelationships among a variety of elements – Columbia University, different hosts and audiences, the media, all levels of the Chinese government, the domestic situation in the United States, the international situation, and Dewey’s expectations and work – against the general background of China’s New Culture Movement and new educational reforms. Dewey’s speeches on democracy, science, and new education were remarkably successful in the first year of his visit to China, but began to meet with resistance from some students beginning in June 1920. Because of the Red Scare in the United States, Dewey had to stay in China. In the second year of his visit, he gave warmly welcomed lectures on the same topics in Jiangxi, Fujian, and Guangdong Provinces. With a deeper understanding of China, Dewey not only identified himself with reform plans but also began to pay more attention to China’s economic problems. His inquiry into the problems confronting China is a good example of what he advocated in his lectures: seeing democracy, science, and new education as a way of thinking and carrying out actions and making intellectual choices while moving forward.  相似文献

The original ceramics typology developed for Younge/Western Basin Tradition Springwells phase (ca. AD 1160–1420) assemblages included three variants known as Macomb Linear, Macomb Interrupted Linear, and Springwells Net Impressed ceramics. This discussion considers how subregional variation in Springwells decorative styles reflects participation in a larger regional social network.  相似文献

Granitoid (pegmatite and aplite) veins in metamorphic rocks and intrusive syenites of central Dronning Maud Land, Antarctica, are flanked by conspicuous light‐coloured alteration halos, which represent the damage zone of fracture propagation. The damage zone is characterized by a high density of sealed or healed microcracks, about 1 order of magnitude above background. Fluid inclusions along healed microcracks in quartz of both pegmatite and alteration halos are inspected by optical and scanning electron microscopy, and their composition is analysed by microthermometry and quadrupole mass spectrometry. The similar inclusion record in the granitoid vein and in the damaged host rock indicates the derivation of the fluids from the hydrous melt phase. The aqueous inclusions bear abundant daughter crystals, mainly silicates, and may represent a hydrous melt. The volatile composition is variable in the system H2O–CO2, with mostly subordinate amounts of N2. Phase separation with partitioning of CO2 into the fluid phase coexisting with the hydrous melt, and possibly immiscibility in the subsolidus range, govern fluid evolution during cooling. The variable CO2/N2 ratio suggests mixing with fluids from an external source in the host rock and vigorous circulation at an early stage of high transient permeability. Experiments have shown that healing of microcracks at high temperatures is a matter of hours to weeks, hence similar in time scale to the cooling of the cm‐ to dm‐thick granitoid veins. In this case, rapid cooling and concomitant crack healing in a system undergoing phase separation causes a broad compositional variability of the inclusions due to necking down, and the underpressure developing in closed compartments precludes a meaningful thermobarometric interpretation.  相似文献

追求生命的永恒是人类共通的理想,各民族神话中都有体现人类追求永生的传说。《山海经》被称为"神话之渊府",在保存了大量神话资料的同时,也通过对增寿、长寿、长生乃至成仙的描述来否定死亡现象。  相似文献

五千年前陶质建材的测试研究   总被引:1,自引:0,他引:1  
迄今为止的考古发掘表明,我国最早的陶质建材,应该是距今5500年左右的凌家滩“红陶块”。考古学家推测其原料为粘土矿物,烧成温度约800~1000℃,且其物理性能与砖质建材较为接近,应为“砖的雏形”,为此,本工作测试分析了凌家滩“红陶块”的物相组成、烧成温度、吸水率与抗压强度,同时对比分析了明砖、汉砖、现代砖的物理性能,发现“红陶块”系粘土原料在950℃以上温度烧制而成,其吸水率和抗压强度由外向内呈梯度变化,内层的抗压强度、吸水率接近于现代砖和汉砖,业已超过明砖样品,所有这些分析结果,皆支持考古学家关于凌家滩“红陶块”为砖的雏型的推测。  相似文献

年画是中国特有的民间艺术形式。本研究介绍了传统年画印制所用红蓝色料的发展历史,选取15种中国古代与近现代常用红蓝色料进行红外光谱分析,并归纳总结了标准样品的化学结构与红外谱图特征。在此基础上,利用衰减全反射傅里叶变换红外光谱仪对三幅清末民初时期的传统年画开展无损检测。结果显示三幅年画的红蓝色料均为合成颜料或染料,包括酸性大红G、酸性墨水蓝G、普鲁士蓝等。本研究扩展了红外光谱在书画文物分析检测中的应用范围,为传统年画色料的无损鉴定提供科学依据。  相似文献
