For the well‐known early Mesolithic site of Star Carr, dating of organic artefacts by accelerator mass spectrometry (AMS) has been hampered by treatment of bone and antler recovered during the original excavations with preservatives. Some, untreated, artefacts were, however, collected after Clark's excavation in 1950. Four of these artefacts were AMS dated in 1995, but two of the dates were significantly younger than the others, and were questionable due to their low collagen yields. These suspect samples have now been re‐analysed, demonstrating that all four artefacts are of similar date. The significance of these dates for the chronology of Star Carr is discussed.  相似文献

Summary. A technological advance in wheel construction, entailing spokes with thickened or strengthened ends, can be detected in Central Europe at the start of the Late Bronze Age. Spokes with thickened ends are seen in Central Europe on full-size wheels, wagon models and wheel depictions. It is argued that this technological innovation had its source in the Aegean, where wheels with thickened spokes are seen not only depicted on late Mycenaean craters but also on Linear B wheel ideograms. The second part of the article discusses a closely-related Central European group of wheel-shaped designs, characterised by forked spokes, found on pin-heads, pendants, decorated belt-sheets, phalerae and belt-hooks. As some of these designs refer to real wheels constructed with thickened or strengthened spoke ends, it is concluded that the designs really represent wheels, although the designs are often so simplified that this is not immediately apparent.  相似文献

One of the most remarkable phenomena in current international politics is the increasing attention paid to “historical injustice.” Opinions on this phenomenon strongly differ. For some it stands for a new and noble type of politics based on raised moral standards and helping the cause of peace and democracy. Others are more critical and claim that retrospective politics comes at the cost of present‐ or future‐oriented politics and tends to be anti‐utopian. The warnings about the perils of a retrospective politics outweighing politics directed at contemporary injustices, or strivings for a more just future, should be taken seriously. Yet the alternative of a politics disregarding all historical injustice is not desirable either. We should refuse to choose between restitution for historical injustices and struggle for justice in the present or the future. Rather, we should look for types of retrospective politics that do not oppose but complement or reinforce the emancipatory and utopian elements in present‐ and future‐directed politics. I argue that retrospective politics can indeed have negative effects. Most notably it can lead to a “temporal Manichaeism” that not only posits that the past is evil, but also tends to treat evil as anachronistic or as belonging to the past. Yet I claim that ethical Manichaeism and anti‐utopianism and are not inherent features of all retrospective politics but rather result from an underlying philosophy of history that treats the relation between past, present, and future in antinomic terms and prevents us from understanding “transtemporal” injustices and responsibilities. In order to pinpoint the problem of certain types of retrospective politics and point toward some alternatives, I start out from a criticism formulated by the German philosopher Odo Marquard and originally directed primarily at progressivist philosophies of history.  相似文献
