Abstract

The Andalusi hydraulic systems of the Iberian Peninsula, constructed by Arabs and Berbers between a.d. 711 and the feudal conquest of Al-Andalus (11–15th centuries a.d.), are today among the most productive agricultural areas in Europe. Their current extension is the result of several enlargements made to the original Andalusi design, irrigating lands initially rejected by the first builders. Understanding the reasons that led Arabs and Berbers to select or reject lands for irrigation is essential for documenting the formation processes of these agricultural areas. Here the topic is approached using the hydraulic system of Ricote (Murcia, Spain) as a case study. Through hydraulic archaeology, excavations, and GIS, it is shown that deep, flat, well-insolated (i.e., exposed to sunlight), slightly saline, colluvial soils were preferred for irrigation while slopes, shady areas, floodplains, and highly saline soils were rejected. Optimizing the water supply for irrigation was not a top priority. The results highlight the need to consider topographical features when studying how past agrarian societies introduced irrigated agriculture to new environments.  相似文献

In the archaeological literature regional centers often receive far less attention than capital regions and the medieval Khmer Empire (ca. 9th to 15th centuries a.d.) is a classic case in point. At its height, the Khmer Empire stretched across much of mainland Southeast Asia, and it remains the most extensive dominion in the history of the region. To date, however, relatively little archaeological work has been completed outside of the capital of Angkor, and we have a limited understanding of the broader dynamics of the Empire. In this paper we begin to address this lacuna at the remote monumental complex of Preah Khan of Kompong Svay, the largest of all the Angkor-period regional centers. We describe the use of remote sensing and ground survey methods to produce the first comprehensive archaeological map of the site. The map data are used to evaluate conventional interpretations of the site as a major industrial complex, urban center and military outpost. The findings have implications for our understanding of early urbanism, industrial production and imperial expansion in the region.  相似文献

This paper reports on the results of archaeological field excavations at the site of Kara-tepe, in the semi-autonomous region of Karakalpakstan in northwestern Uzbekistan. Investigations at the site in 2008–2009 turned up an unusually rich assemblage of remains from a household context. Combined analysis of the household botanical and faunal remains has allowed us to reconstruct the agropastoral practices of local inhabitants in this oasis region during a critical period of social and environmental change in the Early Medieval transition (4th–5th centuries a.d.). The results of the study raise important new questions about agropastoralism in the oases of Central Eurasia, highlighting continuities of practice between oasis and steppe populations, and revealing dynamic changes in these systems over time.  相似文献

Water clock is a vital instrument to tell the time in ancient societies. The Indian water clock stayed in a stereotype since the 5th century A.D., till the entering of British, both in literature and people's life.  相似文献

An archaeometric study was carried out on 40 gold leaf tesserae from mosaics in Italy dated 1st to the 9th century AD. Glass layers and gold leaf were both analysed by X-ray microanalysis. The main aim was the identification of the composition of the glass and of the gold leaf, in order to assess the variations in composition and nature of the tesserae in the examined period.  相似文献

自宋代的塘浦系统开始瓦解以来,吴淞江流域的泾浜体系开始发展。泾浜水系和以后溇的出现,基本上人为形成的。在不断的历史发展中,泾浜体系形成具有干枝结构的网状水系,这种结构非常稳定地存在了近500年。这种结构下的圩田水利模式一般是小圩模式。在冈身感潮地区,泾浜体系比较密集,且末端水系有弯曲化现象;在低地地区,为了排水的方便,河道的干枝体系较为顺直。在这种体系下,治水必须与治田相结合。到后期,随着圩田治理的深化,进一步出现了称为溇的末端水系。  相似文献

This paper presents a study of a representative selection of lustre ceramics dating from the last quarter of the 10th century AD to the second half of the 13th century AD from Egypt, Syria and Iran. The study concentrates on the structure and chemistry of the lustre itself over the historical period considered and has found a number of significant similarities between the production centres studied. Previous work on the reproduction of lustre under laboratory-controlled conditions allows the archaeological data to be related to the historical technological aspects of lustre production. The results obtained, although restricted to the limited number of samples studied, have demonstrated the occurrence of significant differences and similarities between lustre productions during this period. The possible reasons for these changes are discussed.  相似文献

Destruction events in multi-period sites are valuable marker horizons that represent time-synchronous events across the site and sometimes between sites. Destruction layers often preserve rich finds that provide insights into site use. Here we use both macro- and microarchaeological methods to study a destruction event from the late 9th century at Tell es-Safi/Gath in Israel. A major conflagration at this specific location resulted in the consolidation of parts of the roof construction materials, thus enabling us to differentiate between roof, walls and floor materials. We could reconstruct the events which lead to the formation of an approximately 80 cm thick layer. The base of this layer that overlies the floor surface is a thin charred organic material-rich ash layer. As the clays in this layer were not altered by heat and the ceramics still have preserved residues, we conclude that the ash was produced elsewhere and was redistributed to this location. Ceramics that are associated with burnt roof sediments do not have preserved residues. We also estimate the time that each of the accumulation events might have taken, and conclude that this accumulation occurred over decades. The architecture and artifacts found within and beneath the destruction do not allow us to unequivocally identify the function of this area prior to destruction. We do however identify an unusual bin and associated stone pavement, and a corner rich in artifacts, phytoliths and charred organic material. We also show that a wall was built of fired mud bricks; a most unusual occurrence for this time period in the Levant. This study demonstrates well the usefulness of an integrated macro- and microarchaeological approach to understanding the archaeological record, as well as the benefits of using an on-site laboratory.  相似文献
