A review of the Lipke collection raises new questions concerning Egyptian boatbuilding methods for the Khufu I vessel, including the shaping of planking, the purpose, fitting, and spacing of cross‐grain mortise‐and‐tenon joints and the crafting and securing of hook‐scarfs in girders. New data supports the author's contention that the construction of this vessel was abruptly terminated, but contradicts his suggestion that the central girder had no hook‐scarf—it does, but it is unique. Furthermore, detailed plans show how the hood‐ends, sleeves, and papyriform decorations were crafted and joined. A planking‐plan with scale does not always agree with published data. © 2010 The Author 相似文献

Porter, a dark style of beer that was the staple of London in the eighteenth and nineteenth centuries, is conventionally addressed as a discrete invention, suited to large‐scale production, whose appearance led rapidly to enclosure of the trade by a few industrial‐scale producers. This paper by contrast presents the capitalist industrialization of brewing as co‐extensive with, and reinforced by, the long‐term emergence of a consensus definition of porter; the invention story is a retrospective construct that telescopes a century or more of technical change. Balancing established economic accounts, I address the role of product identity as a rhetorical device. London’s greatest brewers were in part assisted in capturing smaller competitors’ trade by the enshrining of large‐scale production as a ‘secret ingredient’ in its own right, essential to the nature of the ‘true’ product. 相似文献

铜鐎斗的器形演变及用途考 总被引:1,自引:0,他引:1
鐎斗是汉至唐代墓葬中常见的器物。通过对铜鐎斗的综合研究,根据柄部的不同,可将这种器物分为四类,其器形变化清晰,地域分布明确,具有一定规律性。铜鐎斗兴起于汉代,盛行于六朝,至唐代趋于消亡。根据器形和分布范围的变化,以及出土器物的组合,并结合中国饮茶习俗的发展历程,推断铜鐎斗应为煮茶的器具。 相似文献
