This paper aims to bring together hitherto neglected archaeological data about the early medieval landscapes of Galicia (north‐west Spain), in order to understand the social transformations this ‘peripheral’ region underwent between the fifth and the ninth centuries and to frame them in the context of wider European debates. Despite its many limitations, the archaeology reveals that until the middle of the seventh century, the late antique society of Gallaecia experienced a previously unsuspected vitality. At this point a socio‐political fragmentation occurred, which was characterized by the strengthening of local power, until a further change took place with the progressive incorporation of Galicia into the Asturian kingdom in the ninth century.  相似文献

The analysis of environmental archives from across the world has demonstrated that human perturbation of the geochemical cycles of trace metals and the resultant atmospheric metal contamination date back, at least, several millennia. However, an understanding of the local processes and timing of changes in trace metal deposition is also essential for a proper global interpretation. The Iberian Peninsula was a major mining area since prehistoric times and the analysis of environmental archives provides a good opportunity to improve our understanding of the history of mining and metallurgy in Europe. We present the results from three 14C dated peat cores from the Xistral Mountains (NW Iberia). These records are used to reconstruct past atmospheric deposition of Ni, Zn, As, and Cd. The chronology of the changes in concentrations and metal accumulation rates was found to be concordant in the three bogs, and showed great similarity to total Pb, Hg, and Pb isotope ratios as determined in previous investigations. They present a consistent view of changes in atmospheric pollution and the importance of metals in the development of human societies, especially: i) the first evidence of atmospheric metal pollution 3400 years ago, which is simultaneous with the expansion of the Atlantic Bronze Koine; ii) a pollution event between 2350 and 2150 years ago, associated to the development of so-called Celtic culture (local Late Iron Age); iii) a dramatic increase of metal fluxes in Roman times; iv) a severe and rapid increase in the last 250 years corresponding to the beginning of the industrial revolution in Europe, reflecting the emergence of the new dominant sources of pollution, and v) the increase of long range atmospheric transport of pollutants. Our data suggest that all detected ancient (until ca. 1450 cal BP) periods of enhanced Ni, Zn, As, and Cd accumulation may have had an anthropogenic origin, related to the onset and development of mining and metallurgy.  相似文献

Making history—in the sense of writing it—is often set against talking about it, with most historians considering writing history to be better than talking about it. My aim in this article is to analyze the topic of making history versus talking about history in order to understand most historians' evident decision to ignore talking about history. Ultimately my goal is to determine whether it is possible to talk about history with any sense.
To this end, I will establish a typology of the different forms of talking practiced by historians, using a chronological approach, from the Greek andRoman emphasis on the visual witness to present-day narrativism and textual analysis. Having recognized the peculiar textual character of the historiographical work, I will then discuss whether one can speak of a method for analyzing historiographical works. After considering two possible approaches—the philosophy of science and literary criticism—I offer my own proposal. This involves breaking the dichotomy between making and talking about history, adopting a fuzzy method that overcomes the isolation of self-named scientific communities, and that destroys the barriers among disciplines that work with the same texts but often from mutually excluding perspectives. Talking about history is only possible if one knows about history and about its sources and methods, but also about the foundations of the other social sciences and about the continuing importance of traditional philosophical problems of Western thought in the fields of history and the human sciences.  相似文献

The Second European Congress on Commerce and City was held in Lille between 15 and 17 November 2000. It was organized by the French Ministry of Economy, Finance and Industry under the umbrella of the French Presidency of the European Union. Its major aim was to discuss how, and under what conditions, the evolution of commerce in Europe can contribute to the renaissance of European cities. The congress included plenary sessions, the presentation of two major studies on commerce and urban regeneration in Europe, three guided study tours, and the discussion of 25 European best practices aggregated into four thematic workshops: city strategies, enterprise strategies, public-private cooperation, and urban planning tools and programmes. This paper identifies those best practices, highlights some of the discussed issues, and presents a synthesis of the congress's declaration.  相似文献

Alzira is situated in a cut-off meander loop of the Rio Júcar. Geo-archaeological study shows that the Islamic city wall was built during the second quarter of the 11th century AD, at a time when the river had a low-amplitude and low-energy flood regime. After mid-century, overbank silts began to invade the city as peak flood discharge increased, with a spate of destructive floods reflected by high-energy deposits during the late 11th century. Urban expansion within the city wall is dated to the later 11th or early 12th century, interrupted by local abandonment and moderate-energy flood silts. Major construction during the mid-12th century was followed by protracted abandonment (after a siege in AD 1171?) and further, moderate-energy flood silts that redistributed occupation and collapse debris. Reoccupation, during the late 14th century, was terminated by catastrophic floods in 1517 and 1571, after which much of the western end of Alzira was not rebuilt. Following further flood catastrophes during the 17th century, parts of the central walled city remained abandoned until the 19th century. with new occupation atop flood sands of yet another disaster in 1864. The change in flood regime after 1150 was a result of deforestation of the watershed, but progradation of a downstream tributary fan after 1517 created an unstable, aggrading floodplain increasingly prone to severe flooding. Climatic anomalies were responsible for periods of recurrent severe floods, archaeologically verified during the 11th and 12th centuries, and historically documented, beginning in 1318. The geo-archaeological methodology illuminates the constructional and settlement history of Alzira, allows distinction of fluvial and cultural components, and provides the necessary microstratigraphic detail and dating control to document the true complexity of alluvial processes during the last 1000 years.  相似文献
