Analysis of detailed geomorphological mapping enables a sequence of glacial events to be established. An ice sheet whose source was to the west of the area of study is shown, by the suites of fluvioglacial landforms produced, to have down‐wasted in situ; meltwaters escaped beneath or through the ice, moving uphill across certain areas. Finally, a sub‐aerial drainage system was established and outwash terraces were spread down valley.  相似文献

Limited excavations were undertaken between 1975 and 1982 in two areas: south of the upper ward gatehouse and in the area of the lower ward eastern entrance. The excavations revealed traces of four bridges, one of which had left clear evidence of the design of its timber piers. Archaeological evidence suggests that all four bridges date from no later than the middle years of the twelfth century. The eastern gatehouse was shown to be a comparatively insubstantial structure, in spite of a major rebuild, suggesting that the main defence in this area was concentrated forward on the great barbican. The latter awaits future investigation. Limited re-examination of the structure of the lower ward Westgate and finds from this area enabled a sequence of gatehouse development and use to be suggested. South of the upper ward gatehouse excavations uncovered two substantial pits; the southern one was a lime kiln, sealed by construction of the successive bridges to the upper ward, and probably associated with the building of the ‘country house’ in the 1070S. The second pit, on the northern side of the upper ward ditch to the south-west of the upper ward gatehouse, could not be fully excavated and its purpose is rather more enigmatic; it was most likely another lime kiln. Investigation of the original topsoil on the northern lip of the upper ward ditch has identified early occupation levels apparently preceeding construction of the country house.  相似文献

At the center of Sophocles’ Antigone is a struggle to reconcile personal beliefs with the needs or dictates of society. At no time is such a struggle more relevant than in periods of war, so it is not surprising that new adaptations of Antigone cluster around periods of armed conflict, whether between nations or within a single nation itself. In Luis Rafael Sánchez’s The Passion of Antígona Pérez (1968)—the subject of this essay—the nation or territory in question is one not typically featured in Western anthologies of drama: Puerto Rico, in the troubled possession of the United States.  相似文献

The article reviews the situation of the critical edition of the “entremeses” and other comic short plays of Calderon, highlighting numerous textual and interpretative problems in the current editions, and proposing solutions for establishing the correct text of many passages. It also provides a number of explanations that clarify other references.  相似文献
