Between Biblical ‘Ammon’ and Early Umayyad ‘Amman’ lie a thousand years of Graeco-Roman Philadelphia. During this period the population of the classical city and its hinterland reached a peak not seen again until the 20th century. During the Middle Ages, however, the population shrank dramatically, the city was abandoned, an island of crumbling grandeur, surrounded by an equally depopulated landscape—the skeleton of a once thriving network of roads, villages, farms, monasteries, and field-systems. Even after re-settlement began at Amman in the 1870s, population in city and hinterland was thin and scattered, the abundant ruins often well-preserved. Development throughout the Belqa—the extensive fertile hinterland of Amman, was evident but relatively slow for some 70 years. After 1948, the impact of successive waves of refugees on top of a region-wide population explosion, began to transform the landscape and devastate the archaeological record. The process is accelerating and spreading. Even in the city, many substantial buildings captured on 19th century photographs have been lost to development; in the hinterland, the vital rural context of a great Classical city has been extensively overwhelmed. Nevertheless, much can yet be salvaged. Beginning with Seetzen in 1806, westerners began to explore ‘east of Jordan’. Many recorded their observations and some mapped, painted, drew, and increasingly photographed—including from the air. Collectively, the corpus of evidence is considerable, ranging from the observations of scores of early western visitors to the more recent archaeological surveys of the 1970s. Appropriately for present purposes, outstanding amongst such visitors and explicitly scientific and systematic were the PEF surveys of Warren in 1867 and Conder in 1881.  相似文献

Neutron activation analysis has been used to characterize 60 metal objects from the Moche site, of which four are associated with the Chimú Period, two with the Early Chimú Period and the others with various Moche IV contexts. Different types of utilitarian and non‐utilitarian objects were analysed to identify the metals present, and to investigate their chemical composition and their eventual source. The results clearly indicate the distinction between Chimú and Moche artefacts and confirm the generalized opinion that arsenic bronze was popular after ad 900. They also indicate that gilding copper objects with gold was already a common practice during the Moche era.  相似文献

Mortoniceratid ammonites of the Eromanga Basin of Queensland, although uncommon, are reviewed and reassessed utilising all known collections. Representatives of this group are restricted to the Allaru Formation and almost all specimens are Goodhallites goodhalli, a well-known species from the English Gault. The Allaru Formation overlies the Toolebuc Formation, widely considered to be an essentially isochronous unit because of its unusual sedimentary and geochemical character. Using G. goodhalli, the middle and upper Allaru Formation can be directly correlated with the early late Albian orbignyi and auritus Subzones of the Mortoniceras inflatum Zone as recognized in the reference ammonite zonation embedded in the standard Cretaceous time scale. Overlapping ranges of G. goodhalli and Labeceras and Myloceras allow these common Austral heteromorph genera to be also confidently assigned a late Albian age in Australia, matching their biostratigraphic occurrence in South Africa.  相似文献

Traded down the Purari River by male youth through a network of friends, kuku dipi, as marijuana is known in the Purari Delta, is consumed locally, and traded for guns it is rumoured that the American Mafia bring in submarines. The movement of kuku dipi is part of a constellation of informal trade that has emerged alongside the large‐scale logging and oil projects in the Gulf Province. These networks involve the exchange of alcohol, pornography and radios by logging ship crews for live birds, crocodile skins and other local flora and fauna. Numerous sets of speculations have arisen about the seen and unseen transactions that these exchanges are felt to entail. Focusing on aspects of kuku dipi's use and movement in the Delta, I examine some of the explanations and anxieties around this illicit commodity. Doing so provides insight into kuku dipi's social impact and illuminates how the Purari's engagement in this trade is an attempt to transcend and cope with the economic and political disparities caused by the current resource extraction projects.  相似文献

This research addresses the strength of the homeland security policy regime that was constructed after the terrorist attacks of September 2001. We argue that homeland security provides a preeminent example of the challenges of developing policy regimes that focus policymaking on a common goal across diverse subsystems. All the ingredients for fashioning a powerful regime were in place after the terrorist attacks of September 2001—a common purpose, engaged stakeholders, and institutional redesign. But for a variety of reasons that we discuss, the results are far from cohesive. The lessons we draw are more general ones regarding factors that influence the strength of boundary‐spanning policy regimes.  相似文献
