The medieval discipline of the ars dictaminis (or dictamen), which flourished during the 12(th)-14(th) centuries, can be considered as an adaptation of classical Latin rhetoric to the communicational needs of the medieval society. Yet, although the relation between the teaching of the ars and its practice is an important one, it has rarely been addressed because of the persistence of numerous misunderstandings about the various different levels at which the ars was taught. This article offers some suggestions to fill this gap.  相似文献

Following the Malta Convention/Valletta Treaty the preferable way for the physical protection of archaeological sites is in situ preservation. When planning in situ preservation, in addition to other issues, it is also necessary to consider changes in physical environment and their impact on in situ preserved remains. This is especially important when human interaction takes place. Recently, an increase in construction on the top of archaeological sites has occurred, thus the effects of heavy equipment compaction need to be studied in more detail.

This paper presents research on the effects of the use of heavy equipment (e.g. rammers and rollers) compaction on archaeological remains. For the purpose of our research, laboratory testing has been performed. In a custom-made steel box, artificial archaeological sites were created using layers of sandy silt and gravel. A variety of archaeological and modern artefacts were placed in these created environments. Some of them were equipped with strain gauges for deformation recording. Through a series of tests a servo-hydraulic piston was used, which simulated the dynamic loading of the artificial sites. Humidity and temperature were recorded before, during, and after each test. Since layers and artefacts were three-dimensionally recorded before and after each test, compaction of layers and movements of artefacts could be studied. With attached strain gauges and visual inspection following each test, deformations and thus damage to artefacts during different stages of loadings was recorded.

The goals of our laboratory tests were the development of a new methodological approach to study the effects of heavy equipment compaction to the archaeological sites, getting an insight into the problems of such tests, and the estimation of the applicability of their results. With the presented results, our research has been a step towards better understanding the effects of heavy equipment compaction on archaeological remains and thus to the preservation of archaeological sites in situ.  相似文献

Abstract

The recent political changes in the Czech Republic have led to a major re‐evaluation of the role of the countryside. An extensive Village Restoration Programme is now underway, which is here described, with a detailed example from south Moravia. The holistic nature of the programme is notable.  相似文献

The present-day maritime landscape of Western France forms the geographical framework for a recent research project dedicated to the archaeological study of ancient fish-traps, combining regional-scale and site-scale investigations. Based on the compilation and exploitation of a large unpublished dataset including more than 550 sites, a preliminary synthetic study allows us to present some examples of synchronic and thematic approaches, and propose a morphological classification of the weirs. These encouraging first results open up new perspectives on fish-trap chronology closely linked to wider studies on Holocene sea-level changes.  相似文献

The fifth to sixth centuries were a time of significant change in rural settlement, land use, production levels and productive technology in many regions. Archaeological and related discoveries suggest that in western Europe, specialized market- and state-oriented production gave way to mixed animal husbandry and diversified farming more suited to local terrains. This was accompanied by a widespread transformation of rural settlement. In contrast, the eastern Mediterranean experienced rural settlement expansion, intensification of land use, increased market-oriented agricultural production, and a significant change in oil and wine press technology. These changes seem to reflect the socio-political context in both east and west during this pivotal period.  相似文献

Historical archaeologists have advocated the need to explore the archaeology of the modern city using several different scales or frames of reference—the household and the district being the most common. In this paper, we discuss the value of comparisons at larger scales, for example between cities or countries, as a basis for understanding archaeology of the modern western city. We argue that patterns of similarity and dissimilarity detected at these larger scales can (and should) become part of our interpretive and explanatory armoury, when it comes to understanding patterns and processes at smaller scales. However, we also believe that these larger scale enquiries do not by any means exhaust (or diminish the importance of) the site- or household-specific questions that continue to demand adequate answers. By reporting some of the thinking behind the work that has been done in Melbourne, Sydney and shortly to begin in London, we seek to more clearly establish the value of this broader comparative agenda in urban historical archaeology.  相似文献
