Archaeological research on ironworking in the Horn of Africa is meager and patchy. This paper offers hypotheses for the origins of ironworking in the region. Two conventional schools of thought are analyzed. The first school favors an external origin and the second advocates local invention. The two viewpoints are critically examined and their weaknesses exposed. A third alternative, which, in principle, combines the two, is provided in their place. This looks at the history of the Horn in a broad spatial and integrating perspective. It attempts to show that the current physical barriers such as the Red Sea, the Nile Valley, and the cataracts of the Nile River have not always been as impenetrable as we tend to think. There is evidence that sometimes in the past, people from the opposite sides of these “barriers” shared language, commerce, religion, and politics. The paper also discusses the impact of ironworking in the region and the technological influence of the Horn on sub-Saharan Africa. Finally, the paper offers some suggestions for future directions toward a more comprehensive understanding of Iron Age culture and the socioeconomic history of the region.  相似文献

Due to the persistent socio-economic problems that have beset African countries since the late 1970s, many of them have been forced to accept IMF and World Bank sponsored Structural Adjustment Programs (SAPs). Ghana came under one such program in 1983. While proponents of the program point to growth in GDP and other measures as evidence of successful adjustment in Ghana, critics have pointed to the negative impacts on the labor market, women, farmers and the like. This paper seeks to add to the debate by examining the impacts of SAPs on housing production, delivery and affordability from 1983–1998. It argues that since shelter is a very important basic need, what happens to its production, affordability and access under the SAPs should be considered among the criteria for judging their success or failure. The paper examines housing affordability in Accra, Ghana, using standard measurement criteria applied by lending institutions to determine affordability. It uses market data to compare and contrast housing prices and income ratios in Ghana from 1980 to 1998. The analysis is based on a combination of primary and secondary data from market surveys, the Ministry of Housing, the Ghana Statistical Services and a variety of other sources. It concludes that not all the dramatic increases in the price of both developed and undeveloped land over the past 16 years can be wholly attributed to the ongoing Structural Adjustment Programs (SAPs) per se. Nonetheless, SAP inspired policies such as currency devaluation and hikes in interest rates have contributed greatly to these changes. The end result is that real estate prices have been pushed beyond the affordability of a significant proportion of Ghana's population.  相似文献

Archaeological data available for reconstructing the Irish Iron Age have expanded rapidly due to the large number of excavations conducted in recent decades as part of large infrastructure projects. This article interprets iron‐production sites dating to the first millennium BC, many of which were discovered as part of those projects, as representing discrete but overlapping communities of ironworking practice. Through a synthesis of recent excavation data, I outline the evidence for different modes of iron production that range from very small scale to ironworking specialists attached to high‐status persons. Developing a socially‐driven reconstruction of this technology provides insight into various aspects of Iron Age society as embedded in local, regional, and pan‐regional communities.  相似文献

Pre-colonial African ironworking was much more than just a technology; it encompassed economic, social, political, symbolic, and even healing components. It is only unfortunate that archaeometallurgical research has not availed equal weight to each aspect, hence the apparent obscurity of some of them. Revealing the multiple facets of healing as manifested in ironworking technology, this paper attempts to rectify this imbalance. Essentially, the paper examines pros and cons of combining ironworking with healing of humans, a phenomenon common among ironworking communities in pre-colonial Africa. It is revealed that by combining the two, iron smelters ensured themselves of gains beyond technology and economy; they also became socially and politically influential. In addition, the paper notes that there existed a very close connection between healing and ritualism not only among smelter–healers but also conventional healers. After a thorough examination, it is found that the connection between the two was also pragmatic and deliberately instituted by the practitioners in order to enhance monopoly of their trade and protect their inventions against interlopers.  相似文献

An experimental approach has been used to establish whether medieval ironworking activity could be identified in peat bogs using mineral magnetic measurements. The research project comprised three elements. First, magnetic susceptibility and remanence properties were obtained for materials from an experimental iron smelt, in a furnace of medieval design, and from material collected during the excavation of the medieval bloomery at Llwyn Du in Coed y Brenin, Snowdonia. Materials sampled and measured included charcoal, aerial dust, roasted bog ore and furnace dust. A second experiment determined whether small amounts of aerial dust released from the furnace could be detected in accumulating peat samples. This was achieved by sprinkling small quantities of dust on to a constructed ’peat core’ that had no detectable magnetic signature prior to the addition of the dust. The application rates used were within the range expected to fall on a peat bog located close to a medieval furnace. Thirdly, mineral magnetic measurements were made on a peat core collected close to the Llwyn Du bloomery. The results confirm that roasted bog ore, aerial dust released from and dust accumulating in the furnace after a smelt, are magnetically detectable. The aerial dust and roasted bog ore produced enhanced susceptibility and remanence signatures in the constructed ’peat core’ experiments. Peaks in IRM(0.88T) and HIRM were measured in the Llwyn Du peat monolith and appear to correlate with a time when the medieval bloomery was operational. The results presented here suggest that it is possible to identify evidence of past ironworking in peat bogs using mineral magnetic measurements and that the signatures remain well preserved in the peat record even after burial for several hundred years.  相似文献

Summary.   This article explores the social significance of metalworking in the British Iron Age, drawing ethnographic analogies with small-scale, pre-industrial communities. It focuses on iron, from the collection of ore to smelting and smithing, challenging the assumption that specialized ironworking was necessarily associated with hierarchical chiefdoms, supported by full-time craft specialists. Instead, it explores more complex ways in which social and political authority might have been associated with craftwork, through metaphorical associations with fertility, skill and exchange. Challenging traditional interpretations of objects such as tools and weapons, it argues that the importance of this craft lay in its dual association with transformative power, both creative and destructive. It suggests that this technology literally made new kinds of metaphorical relationships thinkable , and it explores the implications through a series of case studies ranging from the production and use of iron objects to their destruction and deposition.  相似文献

Aberdulais Falls     
Abstract

Aberdulais Falls is a multi-period site, important because it participated in the early development of three of the major metals industries of Wales – copper smelting, ironworking and tinplate manufacture. For three centuries the River Dulais provided a natural head for water powered plant, the earliest of these being a copper works thought to have been established here in 1584. It was the site of a corn and grist mill c1765-1819, during which time it was a popular subject for travelling artists, Turner among them. This article is an interim report based on the archaeological work undertaken from 1982-5, and represents the author's term as Site Archaeologist at Aberdulais Falls. It argues that the extant remains belong, almost exclusively, to the two final periods of industrial activity – ironworking (c1819-40) and tinplate manufacture (c1840-90).  相似文献

Over the past 20 years, the earliest prehistory of Cyprus has been completely rewritten as a result of new excavations, survey work and high-resolution radiocarbon dating. This study attempts to summarise the earliest chapter in the prehistory of Cyprus, focusing on published and unpublished results from several new sites and surveys. I attempt to place these results in an interpretative context that focuses on early seafarers, fisher-foragers, and the people who were instrumental in establishing the earliest agricultural communities on the island of Cyprus. The pace of change in the study of both the Late Epipalaeolithic and earliest Neolithic is such that all current interpretations must remain open-ended. Nonetheless, these new streams of evidence demand an interim assessment, not least in order to integrate Cyprus into current interpretations of interaction amongst seafarers, fisher-foragers and early agriculturalists in the wider Mediterranean world.  相似文献

Utah is one of the top producers of oil and natural gas in the United States. Over the past 18 years, more than 4.2 billion gallons of wastewater from the petroleum industry has been injected into the Navajo Sandstone, Kayenta Formation, and Wingate Sandstone in Carbon and Emery Counties, central Utah, where seismicity has increased during the same period. Previous studies have attributed this seismicity to coal mining. Here, we present evidence for wastewater injection being a major cause of the increased seismicity. We show that, in the coal mining area, seismicity rate increased significantly 1–5 years following the wastewater injection, and the earthquakes, mostly with magnitudes <3.0, are concentrated in areas seismically active prior to the injection. Using simple analytical and numerical models, we show that the injection in central Utah can sufficiently raise pore pressure to trigger seismicity within 10–20 km of the injection wells, and the time needed for the diffusion of pore pressure may explain the observed lag of seismicity increase behind the commencement of injection. The b‐value of these earthquakes increased following the wastewater injection, which is consistent with these events being injection‐induced. We conclude that the marked increase in seismicity rate in central Utah is induced by both mining activity and wastewater injection, which raised pore pressure along preexisting faults.  相似文献

Ghana's past is being destroyed at a rapid rate. Although the Ghana Museums and Monuments Board has in some instances successfully intervened to stop the illicit trading of antiquities, the destruction of archaeological sites as a consequence of development over the past two decades has been staggering and the pace is accelerating. The potential of the legislation that established the Ghana Museums and Monuments Board and empowered it to manage and preserve the country's archaeological past has not been realized. The lack of political action, limited relevant public education, insufficient funding, and the poverty of the majority of the Ghanaian populace have allowed for the widespread destruction of both sites and historic buildings. Conspicuously, both the absence of integrated development planning by the Ghanaian government and the inability of development partners (both foreign and domestic) to recognize the potential value of cultural resources have contributed significantly to the continued loss of the archaeological record. While the antiquities trade is a continuing threat to Ghana's cultural resources, it is, in fact, tourism and economic development that pose the major menace to the country's archaeological past. This article reviews the history of cultural resource management in Ghana, including both traditional attitudes toward preservation and current legislation. Case studies are used to illustrate the problems faced. Actuellement le passé matériel du Ghana disparaît très rapidement. Le Conseil des musées et des monuments du Ghana a réussi à intervenir dans certains cas pour arrêter la traite illicite en antiquités. Toutefois, la croissance rapide du développement urbain au fil des derniers vingt ans a entraîné une énorme destruction de sites archéologiques qui ne fait qu'accroître. Les lois établissant le Conseil des musées et des monuments du Ghana lui ont en même temps accordé les pleins pouvoirs en mesure de la gestion et la préservation du passé archéologique du pays, malheureusement les possibilités de cette législation n'ont jamais été réalisées. Plusieurs éléments contribuent à la destruction très répandue de sites et de bâtiments historiques, dont le manque de prises de mesures politiques, d'éducation publique pertinente, de fonds, et la misère dans laquelle vivent la plus grande partie de la population ghanéenne. Il est évident que l'absence d'une planification intégrée pour le développement de la part du gouvernement ghanéen et l'incapacité des partenaires en développement (nationaux ainsi qu'internationaux) de reconnaître la valeur potentielle de ressources culturelles sont deux éléments supplémentaires clés qui contribuent de façon importante en la perte continue de vestiges archéologiques. La traite en objets antiques présente toujours une menace pour les ressources culturelles du Ghana. En fait le tourisme et le développement économique représentent une menace encore plus importante à la préservation du passé archéologique du pays. Cet article revoit l'histoire de la gestion des ressources culturelles au Ghana, comprenant à la fois les positions traditionnelles envers la préservation ainsi que la legislation actuelle. Des études de cas éclairent les problèmes actuels.  相似文献

Recent studies of elevated carbonate boulder deposits on several rock islands near Bangkok have indicated that Thailand's capital city may not be as protected from typhoon strikes as previously thought. Here, new evidence is presented for past high‐energy wave (HEW) events in the form of statistically significant patterns of boulder alignment on exposed rocky shorelines of Ko Larn island. The long‐axis orientations of 193 coastal sandstone boulders were analysed across four study sites. Several scenarios for the unimodal, bimodal, and polymodal patterns found can be envisaged. Either the most recent HEW event was the strongest—in which case most clasts were rearranged unimodally (one observation site), or the strongest HEW event was earlier and subsequent weaker ones realigned only smaller boulders to produce bimodal or polymodal patterns (three observation sites). Inferred northeastward or eastward onshore flow directions are consistent with palaeo‐typhoons penetrating into the Bay of Bangkok on northwestward curving tracks. The calculated minimum flow velocities required to transport all sampled boulders are 5.5–7.8 m s?1, similar to other findings throughout the Asia‐Pacific region. It was observed that the absence of a fitted boulder geomorphology lends credence to the earlier proposed time frame of 150–200 years between typhoon phases in the upper Gulf of Thailand. The current work has provided additional insights into the characteristics of past HEW events that have a possibility of reoccurring again at some time in the future. Our findings continue to raise awareness for a reassessment of the risks of coastal hazards for the Chao Phraya River delta and densely populated Bangkok, for which storm surge modelling should be an urgent priority, so as to give better perceptions on how typhoon‐driven marine incursion would impact the city.  相似文献

The information which can be extracted from studying craft and production in past societies is by no means limited to technology and exchange. Analysing the chaîne opératoire of iron production in medieval society provides a new perspective and knowledge of its role for urban development. Seen as a complex network of economic, social and material relations, craft and production are embedded in society and have the power to influence it. This article presents and discusses the remains of blacksmithing found at the site of Rådhuspladsen ('City Hall Square') in Copenhagen. The analysis focuses on the scale, types and organisation of the ironworking, as well as identifying the people who may have been involved, including their social and geographical networks. This study aims to better understand the role of iron production for the development of medieval Copenhagen and in general, its role in medieval Danish towns.  相似文献

It is essential to combine genealogical and collective biographical approaches with network analysis if one wants to take full advantage of the evidence provided by (hereditary) personal names in historical and linguistic onomastic research. The naming practices of rural families and clans from the 18th to the 20th century can bring us much fresh information about their enduring attitudes and values, as well as about other mentalities of everyday life. Personal names were cultural symbols that contained socially shared meanings. With the help of genealogical method it is possible to obtain a more nuanced understanding of these past naming practices, for example by comparing the conventions of different communities. A long-term and systematic empirical research also enables us to dispute certain earlier assumptions that have been taken for granted in historical onomastics. Therefore, the genealogical method is crucial in studying the criteria for the choices of personal names in the past.  相似文献

Archaeological and ethnological evidence from the site of Efutu in Ghana is used to indicate the African cultural background of people imported into the Caribbean for enslavement in historical times. Historical, oral and ethnographic data are cited as bases for identifying the characteristics that enabled the enslaved people in the Caribbean successfully to establish independent communities and to put up a prolonged resistance against colonial powers. The heritage of Maroon communities in Jamaica is then discussed in order to identify continuities and discontinuities in African traditions among Caribbean societies.
Résumé Les témoignages archéologiques et ethnologiques du site d'Efutu au Ghana servent à donner des indications sur le passé culturel africain des gens importés aux Antilles comme esclaves aux temps historiques. Des données historiques, orales et ethnographiques sont citées comme bases pour l'identification des caractéristiques ayant permis aux esclaves des Antilles de parvenir à établir des communautés indépendantes et d'opposer une résistance prolongée aux puissances coloniales. L'héritage des communautés d'esclaves marrons en Jamaïque est ensuite discuté afin d'identifier les continuités et discontinuités des traditions africaines parmi les sociétés caraïbes.

Abstract

Throughout their recent history suburbs and suburban society have been characterised by a number of writers — including historians — as being dull, detached, monotonous, lacking in community spirit and devoid of cultural activity. The aim of this article is to challenge these negative stereotypes by examining the reality of community life in the classic suburban town of Surbiton before 1914. It sets out a framework within which communities can be defined and analysed and argues that the criteria used to identify working class communities in the past are not necessarily applicable to more middle class suburban communities. The historical evidence for community life and identity in Surbiton before 1914 is provided by the existence of clubs and societies; sporting and leisure activities; participation in cultural events; support networks when necessary; multi-class activities; and enlightened middle class leadership.  相似文献

This study examines perceptions of the environment in farming communities in the forest ecotone of Ghana. It places local knowledge within a socio-economic and historical context and argues that knowledge is continually evolving, attempting to solve existing problems and discovering new ones. It maintains that favourable conditions exist in farming communities for environmental actions and development approaches based on sustainable development, since these areas have suffered from the negative effects of degradation. However, major constraints exist within the wider political economy and policy framework, which is still locked into environmentally-hostile export-oriented production, and political models which marginalize rural people.  相似文献

Leprosy is a chronic infection of the skin and peripheral nerves caused by the pathogen Mycobacterium leprae. Its impact on human populations and societies of the past as well as its phylogeographic patterns around the world – at least in modern times – has been well documented. This slow growing bacterium has been shown to exist in distinct ‘SNP types’ that occur in relatively defined parts of the globe. The routes that the disease followed in the past are, however, still uncertain. This study of ancient-DNA typing of archaeological human remains from Sweden dated to early Medieval times provides genetic evidence that a transmission of M. leprae ‘SNP subtype’ 2G – found mainly in Asia – took or had already taken place at that time from the Middle East to Scandinavia. This finding is unique in the history of leprosy in Europe. All human specimens from this continent – both modern and ancient – that have been tested to date showed that the one responsible for the infection strains of M. leprae belong to ‘SNP type’ 3, whereas our results show that there were some European populations that were hosts to bacteria representing ‘SNP type’ 2 of the species as well.  相似文献

Imported Mediterranean pottery recovered from 5th–7th century settlement sites along the south Wales coast indicates that trade and contact between Wales and Byzantium continued following the collapse of the Roman Empire in the early-5th century. It is hypothesised that people as well as pottery continued to travel to Wales from Byzantium, some of whom subsequently settled amongst the local communities. Strontium and oxygen isotope analysis was undertaken on human remains (n = 33 individuals) from four early medieval cemeteries from south Wales. The study identified individuals who may not have been local to the British Isles, thus demonstrating that the isotopic analysis of human remains from Wales can further our understanding of migration to Britain during the early medieval period.  相似文献

Isotopic analyses of tooth enamel from early Neolithic skeletons in southern Germany adds diversity to the picture of the Neolithic transition in central Europe, which has often been described as a wholesale shift in diet and technology. Over the past decade, these isotopic studies have suggested some degree of immigration from nearby indigenous groups, as well as social differences within early Neolithic communities that correlate with immigration patterns. In general, there emerges pattern a pattern of patrilocal kinship that is consistent with independent genetic evidence, and anthropologically consistent with the potential identification of Neolithic ‘nuclear families’; and finally, specialisation of subsistence activities, such as livestock herding and cultivating, probably along hereditary lines.  相似文献

This paper discusses the results of a detailed functional study of 16 microlithic backed tools made on quartz, and newly excavated at Sibudu Cave, KwaZulu-Natal, South Africa. The layers associated with the artefacts have OSL ages of 61.7 ± 1.5 ka, 63.8 ± 2.5 ka and 64.7 ± 1.9 ka and represent the Howiesons Poort Industry at the site. I show that more than 50% of the pieces could hardly have been used in any way other than to tip arrows in a transverse position. This outcome supports previous inferences that some of these small stone tools, and perhaps a bone point from the same context, signify the use of bow and arrow technology during the Middle Stone Age. In addition to transversely hafted arrow tips, there is also evidence that some of the tools could have been hafted diagonally. Such tools could have been used equally successfully as arrow tips or barbs, or as barbs for hand-delivered spears. The variation in hafting configuration for these geometric shapes signifies hunting technologies that were flexible and most likely adapted according to need, preference, season and/or prey type.  相似文献
