This article explores the various problems associated with dating brickwork. It does so by combining information gathered from measuring surviving buildings with a survey of recent literature on the subject. Focusing on the seventeenth century, it seeks to show how the various techniques used in making and laying bricks might have changed in the period and to what extent these can be used to provide a tentative dating of surviving fabric. It also outlines the limitations of any such analysis, calling into question various existing recording methods.  相似文献

Introduction     
The settlement on Nor'nour, a small island in the eastern group of the Isles of Scilly, presents a most unusual complex of at least three structural phases, accompanied by a rich and varied assortment of artifacts in bronze, enamel and pottery. Roman jewellery was made on the site, which was excavated from 1962 to 1966.

The presence of a Bronze Age population was clearly indicated. A room built in the form of a Scillonian Passage Grave, with sherds similar to those of the primary urns at Knackyboy Carn, suggest a date of c. 1200 B.C. for this group. In the early Iron Age, c. 600 B.C., immigrants from western Europe, particularly perhaps from Brittany, reached the island. Room I was altered to the form of a wheelhouse, which still clearly shows the features of its type. At the same time a D-shaped room was added to the eastern side of the wheelhouse and seems to have been used as a kitchen. An extensive kitchen-midden lay east of this additional room and to the north-east a workshop was made containing three well-made pits and an enclosed hearth or furnace area.

The latest phase showed a complete change; the wheelhouse became the finishing-room in the manufacture of Roman jewellery and, probably, a store for the import and sale of objects from western Europe. Roman coins found here date from A.D. 74 to A.D. 383. There is also some evidence for the early and gradual subsidence of the Scillonian archipelago.  相似文献

The excavation of four hundred complete and partial in situ burials from the Hospital of St. John the Evangelist, Cambridge, represented one of the largest medieval hospital osteoarchaeological assemblages from the British Isles. The significance of the group is enhanced by the detailed investigation of a carefully maintained network of pathways associated with the cemetery, the archaeological sequence that pre- and post-dated its use and a number of contemporary properties that were situated immediately outside its bounds. This evidence allows the cemetery to be placed within its urban context in a way that is rarely possible. The overwhelming majority of the burials were extended west-east aligned supine inhumations without grave-goods. Atypical burials included examples aligned east-west and south-north, a double burial, a prone burial and individuals buried with a jet crucifix and a brooch. Other significant finds included a nearby pit with four bodies in it, an anthropomorphic bone handle and a reused cruciform horse harness pendant. The proportion of males and females in the burial population is similar, whilst individuals who died under the age of sixteen are relatively uncommon and individuals aged under five are completely absent.  相似文献

Pollen from intestinal contents of mummies, backed by macrofloral analysis, provides important clues to diet, medicines, and season of death. Intestinal contents were recovered from the Piraino 1 mummy from the “Sepulcher of the Priests”, Piraino Mother Church, in the province of Messina, Sicily. Using standard palynological methods and pollen concentration technique, we quantified the numbers of pollen grains per gram of coprolite. The pollen spectrum was dominated by Polygalaceae, the Milkwort Family. Polygalaceae pollen is rarely found in archaeological sites. Based on comparison to published keys, we determined that the pollen came from a species of Polygala. Polygala contains species with medicinal value. We found nine other pollen types. Traces of Potamogeton (pondweed) was observed in preliminary scans. Multiple grains of Brassicaceae (mustard family), cereal (cultivated grains), Typha (cattail) and Cheno-am were found. Single grains of Castanea (chestnut), Fabaceae (bean family), Salix (willow), and Solanaceae (tomato family) were found. The preservation of the pollen was poor except for Polygala and the cereal pollen. Brassicaceae and Cheno-am have been part of the natural pollen spectrum in Sicily since ancient times. Cereal grains were consumed with prepared food. Importantly, background arboreal pollen was nearly absent. This indicates that Piraino 1 died during months of low pollination. The absence of olive pollen is important since this plant in Sicily reaches its maximum pollination in May and June and tapers off rapidly by mid-June. Therefore, absence of the key warm season airborne pollen type suggests a post-June death. Macrofossils, especially residue from grape pulp, indicates a death in September to November. His cause of death was likely a result of multiple myeloma. The methodological differences between archaeopalynology and forensic palynology are summarized. We suggest that the palynological methods presented here should be adopted for human remains analysis in forensic palynology.  相似文献

The earliest known iron artefacts are nine small beads securely dated to circa 3200 BC, from two burials in Gerzeh, northern Egypt. We show that these beads were made from meteoritic iron, and shaped by careful hammering the metal into thin sheets before rolling them into tubes. The study demonstrates the ability of neutron and X-ray methods to determine the nature of the material even after complete corrosion of the iron metal. The iron beads were strung into a necklace together with other exotic minerals such as lapis lazuli, gold and carnelian, revealing the status of meteoritic iron as a special material on a par with precious metal and gem stones. The results confirm that already in the fourth millennium BC metalworkers had mastered the smithing of meteoritic iron, an iron–nickel alloy much harder and more brittle than the more commonly worked copper. This is of wider significance as it demonstrates that metalworkers had already nearly two millennia of experience to hot-work meteoritic iron when iron smelting was introduced. This knowledge was essential for the development of iron smelting, which produced metal in a solid state process and hence depended on this ability in order to replace copper and bronze as the main utilitarian metals.  相似文献

Modern urban economic theory and policymakers are coming to see the provision of consumer‐leisure amenities as a way to attract population, especially the highly skilled and their employers. However, past studies have arguably only provided indirect evidence of the importance of leisure amenities for urban development. In this paper, we propose and validate the number of tourist trips and the number of crowdsourced picturesque locations as measures of consumer revealed preferences for local lifestyle amenities. Urban population growth in the 1990–2010 period was about 10% points (about one standard deviation) higher in a metro area that was perceived as twice more picturesque. This measure ties with low taxes as the most important predictor of urban population growth. “Beautiful cities” disproportionally attracted highly educated individuals and experienced faster housing price appreciation, especially in supply‐inelastic markets. In contrast to the generally declining trend of the American central city, neighborhoods that were close to central recreational districts have experienced economic growth, although at the cost of minority displacement.  相似文献
