This paper presents the debate over the presence or absence of keels in the construction of Egyptian ships of the dynastic period. It contains an analysis of ship representations and models dating to the 18th–20th dynasties of the New Kingdom (c.1539–1077 BC) that provide evidence for the introduction of keels in Egyptian shipbuilding, and new archaeological material from excavations at Thonis‐Heracleion that sheds more light on the question. 相似文献

Nationalism and revolution have generally been held to go together. Many nation‐states have had their origins in revolution, from the Americans in the 18th century to a host of Third World nation‐states in the 20th century. Generally, both modern revolutions and modern nationalism have the same origins, in 18th century Enlightenment thought. But this paper argues that, despite this common origin, the principles of revolution and nationalism are divergent, and can set one against the other. Revolutions emphasise freedom and equality; nationalism emphasises integration and unification. These principles can clash, though not inevitably and not always. The paper examines the 1789 French Revolution, the 1848 revolutions and the 1917 Russian revolution. It shows that in the first two cases, revolutionary aspirations came up against and were eventually displaced by nationalist aims. In the case of 1917, revolution paradoxically, and unintentionally, institutionalised nationalism. These examples show that, though linked at some high level of modern thought, revolution and nationalism express different and at times divergent strands of modernity. 相似文献

This study deals with the mineralogical and chemical characterization of archaeometallurgical material from the Roman archaeological site of Castra (Ajdov??ina, western Slovenia). Samples were initially analysed via optical microscopy and X‐ray powder diffraction, with the composition of individual phases then determined using scanning electron microscopy coupled with electron‐dispersive spectroscopy, and Raman microspectroscopy. Chemical investigation was carried out by using inductively coupled plasma atomic emission spectroscopy to measure the major element content. The results showed that the slag originated from iron smithing operations, with calcium‐rich olivines, as well as wuestite and leucite, the most abundant phases. The investigated slags were also found to be characterized by significantly high lime levels, which probably promoted the formation of the calcium‐rich olivines. 相似文献
