Palace lanterns were important and highly visible decorations in the imperial palace in Beijing, China, during the Qing dynasty (1636–1912). Most lanterns had colourful tassels made of fibres. The study performed a comprehensive investigation of the materials and dyes used for palace lantern tassels preserved in The Palace Museum, Beijing. Eight samples with different colours, including yellow, green and red, from five palace lanterns were analysed. By using ultra-performance liquid chromatography combined with time-of-flight mass spectrometry, the compositions of the dyes were identified quickly, and thus the dyes' origins were explored. A X-ray fluorescence spectrometer assisted in the detection of whether a mordant was used during the dyeing process. As a result, the tassels were all made of silk, discovered through the use of microscopic observation and micro-Fourier transform infrared spectrometry analysis. Different dyeing techniques were found in these tassels: yellow tassels were dyed by cork tree or turmeric by a direct dyeing method; greens were dyed by pagoda bud with an iron mordant, or by the combination of cork tree and indigo using multi-dyeing method; and red tassels were coloured with different acid red industrial dyes. These results provide valuable data for the conservation of ancient textile tassels and contribute to the investigation of other hanging tags.  相似文献

汉魏时期的侍中是皇帝的近幸之臣,其设置、地位、权限几经变化,最终演化成门下省的长官,成为实际执掌国家枢机的"宰相"。曹魏时期是侍中职权转变的关键阶段,特别是它以特殊的方式介入尚书、中书的权力范围,这是非常值得注意的历史现象。本文根据曹魏侍中的设置特点和权力变化,考察其与尚书、中书的密切关系,着重突出曹魏侍中在当时权力格局中的特殊地位。  相似文献

This paper examines the comparatively patchy evidence for the pastoral provision and personal faith of late medieval Scottish combatants below the rank of knight. By examining such sources as papal supplications, royal financial accounts, parliamentary rolls, chronicles, poetry and the cartularies of Scottish monastic houses and burgh collegiate churches, it is possible to identify elite and parish provision of churchmen serving the needs of Scottish troops as they mustered, trained and prepared for battle. In addition, this evidence also highlights a number of cults and relics popular with the social ranks of the ordinary Scottish soldiery, including those of SS Ninian, Leonard, Thomas Becket, Columba, the Blessed Virgin Mary and — often cast as the nemesis of Scottish troops — Cuthbert. However, this survey also points to some tensions between the spiritual interests of Scottish servicemen and their ruling elites.  相似文献
