在新石器时代和青铜时代早期,长城沿线的内蒙古中南部、陕北、内蒙古东南部、辽西等地分布有若干石城带,这些石城带基本上都位于当时农业、半农业文化区的北缘,受到气候环境变迁的影响而南北略有移动,其重要功能之一是为了防御北方民族的南侵。由于这些特点与长城有可比之处,故可称其为长城的"原型"。  相似文献

Stone circles are a common monumental feature of the Mongolian Bronze Age (c. 1500–800BC), frequently occurring in association with other monument types, especially khirigsuurs. Until now the content of the stone circles has not been identified, a fact which has hampered our understanding not only of khirigsuurs and their related cosmology but also of the contemporary economy, owing to a research paradigm that was monument‐focused until very recently. The identification of domestic bovids in these features thus has profound implications for our approach to studying the society of this period and region. These implications, including a well‐developed cosmology and economy which included the ritual sacrifice of at least three different kinds of livestock, are introduced here.

The construction date of the medieval manor house at Clevedon Court has long been said to be ‘c. 1320’, but no explanation or justification has ever been published. Stylistic, documentary and archaeological evidence is assembled to show that, following three distinct building phases, the house was completed during the decade ending in 1320. Analysis of the development of reticulated tracery helps to determine the date of the iconic chapel window. Other elements of the medieval house are considered and explained.  相似文献

There is now broad consensus that the appearance of Clovis in Northeastern North America (Great Lakes, New England) represents a colonization pulse into recently deglaciated landscapes. Due to the increased resource uncertainty that comes with colonizing unfamiliar landscapes, it was hypothesized that the majority tool component of Clovis assemblages, unifacial stone tools, should have been knapped on tool blanks possessing the design properties of longevity and functional flexibility to facilitate exploration mobility and guard against the absence of toolstone sources in the new landscape. These properties are optimized by large, flat flakes, possessing large surface area relative to flake thickness. Since discarded and, at times, exhausted unifacial stone tools do not preserve the original dimensions of the blank upon which they were created – necessary items for a true test of blank morphology selection – this study presents a set of predictions for inferring whether Clovis unifacial stone tool blanks were selected for the properties of longevity and functional flexibility based on evidence that Clovis people actually capitalized on those properties. Due to the nature of Clovis unifacial stone tools, tool size was of necessity used as a proxy for tool reduction, on the grounds that smaller tools are more likely to have been resharpened than larger tools, at least in the case of unifacial flake tools. The results showed that less resharpened tools possessed flatter, less spherical shapes than the more resharpened tools, which possessed more globular, spherical shapes, suggesting Clovis foragers exploited the retouch potential afforded by the larger, flatter blanks. Edge angles showed no relationship with tool reduction, suggesting that Clovis foragers exploited the functional flexibility afforded by flatter blanks by adjusting the edge angle to be either higher or lower as needed. These results are consistent with the notion that human colonizers, who did not know the abundance or location of stone outcrops prior to settling an unfamiliar territory, not only “geared up” before leaving a stone source, but geared up as efficiently as possible by carefully selecting the blanks they chose to carry. Broader implications for such careful unifacial stone tool blank selection are discussed.  相似文献

Brochs are impressive stone roundhouses unique to Iron Age Scotland. This paper introduces a new perspective developed from architectural analysis and drawing on new survey, fieldwork and analogies from anthropology and social history. The study of architectural design and constructional detail exposes fewer competitive elements than previously anticipated. Instead, attempts to emulate, share and communicate identities can be detected. The architectural language of the broch allows complex layers of individual preferences, local and regional traditions, and supra-regional communications to be expressed in a single house design. The proposed ‘productive households’ model moves beyond ideas of competing elites at times of stress, and invites a new debate by expanding a more complex broch concept beyond the Atlantic core.  相似文献
