Traditional understandings of the development of the medieval English longbow and its role in the fourteenth-century ‘infantry revolution’ have recently been challenged by historians. This article responds to the revisionists, arguing based on archaeological, iconographic and textual evidence that the proper longbow was a weapon of extraordinary power, and was qualitatively different from – and more effective than – the shorter self-bows that were the norm in England (and western Europe generally) before the fourteenth century. It is further argued that acknowledging the importance of the weapon as a necessary element of any credible explanation of English military successes in the era of the Hundred Years War does not constitute ‘technological determinism’.  相似文献

A rich stone tool assemblage is described of the Sangoan-type from a potentially semi-primary site, in association with a well-preserved fauna, and in paleo-environmental context. The site appears to be late Middle Pleistocene and contains a high proportion of small to medium-sized mammals (e.g. rodents, monkeys) deposited in low energy conditions. The environment is suggestive of a fringing woodland or riverine forest contained in a subarid climate.  相似文献

Rozefelds, A.C., Dettmann, M.E., Clifford, H.T. & Lewis, D., August 2015. Macrofossil evidence of early sporophyte stages of a new genus of water fern Tecaropteris (Ceratopteridoideae: Pteridaceae) from the Paleogene Redbank Plains Formation, southeast Queensland, Australia. Alcheringa 39,. ISSN 0311-5518.

Water fern foliage is described from the Paleogene Redbank Plains Formation at Dinmore in southeast Queensland. The material, which is based upon leaf impressions, records early sporophyte growth stages. The specimens occur at discrete levels in clay pits at Dinmore, and the different leaf stages present suggest that they represent colonies of young submerged plants, mats of floating leaves, or a mixed assemblage of both. The leaf material closely matches the range of variation evident in young sporophytes of Ceratopteris Brongn., but in the complete absence of Cenozoic fossils of the spore genus Magnastriatites Germeraad, Hopping & Muller emend. Dettmann & Clifford from mainland Australia, which are the fossil spores of this genus, it is referred to a new genus, Tecaropteris. The record of ceratopterid-like ferns adds significantly to our limited knowledge of Cenozoic freshwater plants from Australia. The geoheritage significance of sites, such as Dinmore, is discussed briefly.
