The Tekta? Burnu ship (440–425 BC) sank along a rough and desolate stretch of the Turkish Aegean coast. Archaeological excavation of the shipwreck site by the Institute of Nautical Archaeology at Texas A&M University resulted in the retrieval of hundreds of small fragments from the ship's wooden hull and its metal fasteners. Recent study of this artefact assemblage suggests that the coastal trader was built with pine planks and made‐frames, and assembled by a shell‐based construction method. Fasteners include pegged mortise‐and‐tenon joints and double‐clenched copper nails, and the ship may have had laced extremities consistent with other contemporaneous shipwrecks.  相似文献

20世纪初英国逐步建立了现代社会保障制度.贫困和失业等社会问题的严重化和济贫法制度的失效是这一制度建立的根本原因;来自工人阶级的政治压力是其建立的一个重要原因;费边社会主义、集体主义和新自由主义为这一制度的建立提供了理论基础;德国保险型社会保障制度的建立起了先导作用.英国政府通过一系列的社会立法逐步形成了涉及到养老、失业、医疗、儿童等方面比较完善的福利体系,标志着英国现代社会保障制度的初步确立.它是英国社会保障制度史上一次根本性的转折.  相似文献

The Dutch United East India Company ship Zuiddorp vanished on its way to Batavia in 1712 – its last port of call was the Cape of Good Hope. After its wreck was found on the Western Australian coast, archaeological investigations resulted in the retrieval of 21 lead ingots. Recent study of this artefact assemblage, comprising both great pigs and pieces, suggests that they were of north English origin. Historical records indicate that the Dutch procured large quantities of lead from English sources and maritime trade links between English and Dutch ports were well established at the beginning of the 18th century. © 2012 The Authors  相似文献

The belt of Fernando de la Cerda is on permanent display in the Museo de Telas Ricas, Burgos. Presently, scholars believe the belt dates from 1252–75, is of Hispano-Islamic work and was worn as a baldric. This article suggests that the belt is English, that it was commissioned by King Henry III and was worn around the waist. Henry gave the belt to the count of Champagne, Thibault II, during his first diplomatic visit to France. In turn, Thibault probably gave the belt to Fernando de la Cerda, the infante of Castile, in 1269, at Fernando’s wedding. The belt’s burial with the Castilian infante provides important evidence of the close familial and political relationships that linked the ruling dynasties of north-west Europe during the thirteenth century. Commissioned as a gift and richly decorated, the belt should be seen as an example of the aesthetic accomplishment of Henry III, his use of propaganda and political aspirations.  相似文献

20世纪上半叶,烟草是河南经济作物的一大特色。期间,河南烟草生产迅速发展,形成了烟草种植区域化、专业化的生产模式,并成为全国三大烤烟产区之一,一定程度上改变了河南农业单一的种植结构;同时,河南烟草生产的商品化程度不断提高,不仅满足了国内外卷烟加工工业的市场需求,而且还扩展了河南农村市场的发展空间;在此基础上,烟草集散市场的网络体系初步形成,烟草运销格局也因铁路运输方式的出现而发生重大变化。近代河南烟草的产销不仅提高了农民的生活水平,增强了农民的市场意识,且刺激了河南金融业的发展,并推动了豫中城镇的近代化进程,对河南乃至华北农村的近代社会转型产生了较为深远的影响。  相似文献

Abstract

Rene Descartes presented a number of reasons for his choice of the pineal gland as a logical place for the soul to interact with the physical machinery of the body. It is often stated that one of his reasons was that be believed animals do not have pineal glands, whereas humans alone possess a soul and this small structure. This is a misinterpretation of Descartes. The philosopher knew that barnyard and other animals possess pineal glands, having seen this with his own eyes. His point was that the pineal is unique in humans only because of a special function — acting as the seat for the rational soul.  相似文献

Abstract

Piero Gobetti, who died at an early age in 1926 after a severe beating by Fascist squadristi, is one of the most remarkable figures in twentieth‐century Italian culture. A writer and thinker with deep political commitment, Gobetti launched the reviews and journals during the political crisis in Italy between 1918 and 1925 which provided a meeting point for the otherwise dispersed forces of the Italian Left. The republication of his essay ‘The Liberal Revolution. An Essay of the Political Struggle in Italy’ ‐ the fifth edition since it first appeared in 1924 — has reopened the debate on Gobetti and provides an opportunity to consider Gobetti's ideas outside the context of the often politically motivated interpretations that have been placed on them.  相似文献

Iron production in Korea has traditionally been seen in the shadow of developments in cast iron technology in China, with limited indication for a northern influence via Russia’s Maritime Province. The possibility of the existence of bloomery iron production in ancient Korea has been little explored, and relevant discussion is fraught with speculations based primarily on the early use of cast iron. The recent excavation of a site in South Korea recovered substantial amounts of slag providing direct evidence of bloomery smelting. The accelerator mass spectrometric dating of burnt wood from inside one of the slag pieces showed that the site was in use in the early 3rd century AD or earlier, which is in agreement with the assessment based on ceramic typology. The traits of a bloomery process evident in the slags’ microstructure, shape, composition and excavation context are discussed along with the implications for historical iron technology in Korea, where cast iron and the influence from China have been overly emphasised.  相似文献

This article examines the wealthier inhabitants of Croydon in the late sixteenth and early seventeenth centuries, focusing on differences in wealth, ownership of property and social relationships. Using wills and subsidy lists, four broad categories of people were identified: gentlemen, yeomen, tradesmen and craftsmen and widows. There was no simple gradation of wealth between these groups; although gentlemen were generally among the richest subsidy payers, yeomen and tradesmen could also figure. In terms of social relationships and the ownership of property, there were differences. Gentlemen tended to marry within their own social group, appoint other gentlemen as overseers in their wills and were more likely to own land outside Croydon. The social relationships of yeomen and tradesmen/craftsmen were more focused on the town itself, as were their land purchases. Two groups of individuals can therefore be seen, not one homogenous entity as some scholars have argued.  相似文献

The 'Mardi Gras' Shipwreck is the remains of an early-19th-century sailing vessel lost in approximately 1220 m of water in the Gulf of Mexico. A recent archaeological investigation documented the wreck and recovered several artefacts, including glassware, ceramics, navigational instruments, a cannon, and a stove. Analyses of these artefacts and the surviving hull have led to preliminary conclusions on the nature of the vessel and its crew.
