Archaeometric analysis of ceramic production in Tiwanaku state (c.500–1000 ce): An exploratory study
J. P. Ogalde A. Korpisaari C. Riera‐Soto B. Arriaza C. Paipa P. Leyton M. Campos‐Vallette N. Lara J. Chacama 《Archaeometry》2021,63(1):53-67
The chemical and mineralogical characterization of seven ceramic fragments produced within Tiwanaku state (c.500–1000 ce ) is reported. The instrumental techniques used included X‐ray elemental and mineralogical chemical analysis, Raman spectroscopy, and scanning and light microscopy. The results indicate there are several clay types, although they show similarities, such as the use of a plant‐based temper. The red colour of the decoration is hematite, and manganese oxides such as jacobsite are present in the black. The white colour is a mixture of gypsum and clay, and the orange is a mixture of hematite and clay. The use of colours, the quality of the clays and the temperatures reached during pottery firing point to expertise in ceramic production and to complex decision‐making processes. The multi‐elemental archaeometric approach documented here could become an important tool to shed a light on ancient ceramic technology and the internal variance of Tiwanaku pottery. 相似文献

The reasons why the Western Mediterranean, especially Carthage and Rome, resisted monetization relative to the Eastern Mediterranean are still unclear. We address this question by combining lead (Pb) and silver (Ag) isotope abundances in silver coinage from the Aegean, Magna Graecia, Carthage and Roman Republic. The clear relationships observed between 109Ag/107Ag and 208Pb/206Pb reflect the mixing of silver ores or silver objects with Pb metal used for cupellation. The combined analysis of Ag and Pb isotopes reveals important information about the technology of smelting. The Greek world extracted Ag and Pb from associated ores, whereas, on the Iberian Peninsula, Carthaginians and Republican‐era Romans applied Phoenician cupellation techniques and added exotic Pb to Pb‐poor Ag ores. Massive Ag recupellation is observed in Rome during the Second Punic War. After defeating the Carthaginians and the Macedonians in the late second century bce , the Romans brought together the efficient, millennium‐old techniques of silver extraction of the Phoenicians, who considered this metal a simple commodity, with the monetization of the economy introduced by the Greeks. 相似文献

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce . 相似文献

1908至1910年,王国维曾先后抄录、批校过三种版本的《录鬼簿》,所涉底本有明抄本、清尤贞起钞本和清《楝亭十二种》刻本。而自上世纪四十年代以后,由于前两种抄本在大陆已不可获见,故关于王国维抄校《录鬼簿》及《录鬼簿》版本相关的研究均未能细论其详。本文结合前人对王国维校勘《楝亭十二种》本《录鬼簿》的研究成果,另将台湾傅斯年图书馆所藏的明抄本、尤抄本及国家图书馆藏影抄尤本、日本东洋文库藏王国维据明抄本所作的过录本四种纳入综合考察,在对王国维抄校《录鬼簿》的始末进行细致梳理过程中,发现王氏起初措意于抄校的目的乃是为其正在编纂的戏曲著作《曲录》作参考。但王氏在得到影抄尤本后虽收齐了三种版本《录鬼簿》,却最终放弃当初的刊刻打算,乃是因为刘世珩主持的《暖红室汇刻传奇》计划中早已纳入《录鬼簿》。藉此不仅可明晰王国维早年戏曲研究脉路,而且对《录鬼簿》的版本研究亦可提供新的参考。 相似文献
