A number of cartonnage fragments from the collections of the Petrie Museum, UCL, were examined to identify pigments, media and grounds. The different types of cartonnage made in ancient Egypt are reviewed. Special attention was paid to green pigments, which were shown to be of green earth, or a mixture of Egyptian blue and a yellow, usually goethite or orpiment. Green earth was found in one artefact, dated to the 9th century BC: all other examples were from the Graeco-Roman period. No copper-organometallic greens were present in the examples studied, or Egyptian green, or malachite. Binding media was identified both by ELISA and by GC/MS. A pink colourant was identified as madder, while lead white was used as a white in one example, showing the influence of Roman and Greek pigments on Egyptian art in these later periods. Plant gum, egg, and animal glue were found in different fragments, with mixed media in a few cases. Moganite was found associated with quartz in some preparatory layers by X-ray diffraction, which has not been reported previously as a constituent of ground layers in Egyptian artefacts.  相似文献

Within the globalization process which creaks new common imperatives for cities, it is felt that cities are developing similar promotional approaches. Drawing on two case studies of the promotional strategies and institutions of Paris and London, this paper investigates the balance between economic and purely non‐economic factors in shaping these capitals’ responses to global pressure. The cities’ responses are found to be shaped by national and local factors (institutional, political, cultural) rather than economic ones. Two types of strategies and actors can be outlined, London bang more aggressive and flexible than Paris. Lastly, the report highlights the emergence of new types of institutions within the capitals.  相似文献

The possible existence of a Roman signal station at Whitby has a significant impact upon the study of the Roman defensive system of the North Yorkshire coast and our understanding of the Anglo-Saxon ecclesiastical topography of the area. Whitby lies at the mouth of the River Esk and its associated harbour on the North Yorkshire coast, amidst an intervisible chain of five known signal stations, but is perhaps best known for its Anglo-Saxon monastery founded by the Northumbrian king Oswy in A.D. 657. No absolute archaeological evidence of a signal station at Whitby exists, but the toponym suggests that the site had an association with a signal station or watchtower. It is clear that the existing stations were designed to function as a cohesive system, given their similar form and contemporary dates: communication and intervisibility were therefore essential aspects of this defensive network. Despite this, the stations to the north and south of Whitby—those at Goldsborough and Ravenscar respectively—are not intervisible. A station positioned at Whitby would effectively close this gap in the system.

Attempting to reconcile the near complete absence of archaeological remains with the place-name and geographical evidence, this paper uses geologically determined erosion rates to examine the possibility that such a station existed on the more than three hundred metres of coastal land that has eroded since the Roman period. In doing so it addresses the extent to which archaeologists can reconstruct and work with an ancient coastline on a local scale. Having established the probability of a ‘lost’ station, the paper discusses the results of a GIS viewshed application which address the feasibility of such a station's intervisibility from its neighbouring station to the south. The concluding sections investigate the stations' possible form.  相似文献

The prevalence of osteoarthritis, osteophytosis, intervertebral disc disease and diffuse idiopathic skeletal hyperostosis (DISH) was determined in a group of skeletons excavated from the crypt of Christ Church, Spitalfields. Age-specific prevalence rates were calculated from the group of skeletons for which age at death was known from intact coffin plates. Osteoarthritis of the facet joints occurred most frequently in the cervical and upper thoracic regions and was also common in the lower lumbar spine. The disease was more frequently bilateral in the lumbar spine than in upper regions. Osteophytes were common in the thoracic and lumbar spines, whereas intervertebral disc disease was confined almost completely to the cervical region. Diffuse idiopathic skeletal hyperostosis seemed to be underrepresented in this group, but was more common in males than in females. Age correlated significantly with all the conditions except DISH. Multiple regression analysis was carried out using each of the conditions as the dependent variable in turn. Age accounted for more of the variance than any of the other conditions added as independent variables.  相似文献

By the late fifteenth century the migration field of apprentices to the London companies was very widespread, but from then until the eighteenth century there was a marked contraction. First, the proportion of apprentices coming from London itself increased considerably. Secondly, there were significant changes in the geographical origins of provincial recruits. An attempt has been made to measure this contraction, and it is shown that the average distance travelled by each provincial recruit fell during the period 1486–1750 from 212 km to 111 km. This contraction was due in part to changes in gild and corporation control, but was also affected by major demographic and economic trends. It is suggested that these produced a contraction of London's general migration field which continued until at least 1775.  相似文献

Abstract

After more than 300 years of continuous existence in London, the Royal Society and its 840 Fellows have achieved a worldwide reputation for scientific excellence. This arises not only from their individual prestige and eminence, but also from the superb manner in which the affairs of the Society itself are administered. Here the author is able to reveal some of the reasons for this success, proceeding in an analytical, rather than a critical, approach, describing the Fellowship, the Council, the scientific activities, the publications and the Society's role in international scientific affairs amongst other aspects.  相似文献
