The Construction of the Khufu I Vessel (c.2566 BC): a Re-Evaluation

A re-evaluation of the published reports on the Khufu I vessel suggests: first, Egyptian boatwrights used as much of a plank's original width and length as possible to minimize waste, resulting in unpredictable stealer and scarf placement; second, crafting tenons to be narrower than corresponding mortises may have been one of many standardized techniques of Egyptian boatbuilding; third, temporary and permanent edge-to-edge transverse lashing was an important structural feature. Finally, woven straps instead of ropes were probably used to lash this vessel, and seams were probably sealed with wadding and battens, while the frames appear to have been recycled.

The Planking Clamp from Tårnby: a Medieval Danish Boatbuilding Tool

At the bottom of a well on a medieval farm on the Danish island of Amager, archaeologists found a planking clamp dated by dendrochronology to 1405 AD. ¹ The clamp is of great importance: very few examples have been found or recognised in Northern Europe to date, and this is the best preserved, and thus provides data about its shape and use; and the size of boat it was used in the construction of. It is discussed whether the clamp was used exclusively for boatbuilding or whether it might also have been used in other crafts. It is suggested that copies of the Tårnby planking clamp might be used in future experimental boatbuilding projects.

To Clench or to Rivet: That is the Question

Definitions of the terms 'clench' and 'rivet' proposed by A. E. Christensen are evaluated using the etymology of those terms and recent usage. An alternative definition of 'clench', is proposed, and definitions of 'hooked nail' and 'turned nail' are introduced. It is suggested that the term 'rivet' should be restricted to ferrous fastenings used with metal plates.

New Data on Egyptian Construction Methods in the Khufu I Vessel (c.2566 BC) from the Paul Lipke Collection

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     

The Dover Boat—a Reconstruction Case-Study

The Bronze-Age Dover boat, reconstructed and published by Owain Roberts in 2004, is discussed in regard to the general considerations of reconstructing ancient boat structures in the previous paper. The archaeological evidence shows that the boat had a bottom shape different from that shown in the 2004 reconstruction, and various other aspects, such as the general shape and strength of the hull and the calculation of potential speed when paddled, are questioned, partly drawing on the author's experience with the reconstruction of the Hjortspring boat. A re-assessment of the evidence is called for before any attempts to build a full-scale version of the Dover boat for sea-trials.

A 16th‐Century Ship‐Find from Amager Beach Park,Denmark: description and preliminary interpretation

When establishing the new Amager Beach Park near Copenhagen, Denmark, a small clinker‐built ship dating to the 16th century (dendro‐dated to 1560–70) was discovered. The Viking Ship Museum in Roskilde excavated the wreck in 2004, and parts of the ship were later taken to the museum and recorded in 3D. This article describes the excavation and the documentation, and presents the preliminary interpretation of the ship‐find. The ship is interpreted as a small cargo vessel, probably carrying two masts. Its hull‐form indicates that the vessel was specially designed for navigating the waters of the Sound between Denmark and Sweden. © 2010 The Author     

Sailing the Bremen Cog

The 14th-century Bremen Cog is the only near-complete representative of a type of large ship with a single square-sail which dominated North European waters for c. 200 years. The evaluation of sailing properties, seaworthiness, potential and characteristics of two replicas is made by professional seamen who have taken them to their limits. Their judgements need to be recorded now, or they will be forgotten especially as systematic tests and sea-trials have been limited and documentation lost. The replicas' captains' expert opinion on the Bremen Cog as a sea-going vessel is a rare case of long-term evaluation of a large-scale experimental-archaeology project.

曾侯乙尊盘采用失蜡法工艺铸造毋庸置疑——与《中国青铜时代不存在失蜡法铸造工艺》讨论

近年来,学术界对曾侯乙尊盘铸造法讨论颇多。本文通过埘范铸说的质疑和亲身经历的仿制实验进行分析,认为曾侯乙尊盘用范铸法铸造存存诸多技术障碍,尊盘主体及所有附饰皆应为失蜡法铸造。并且认为失蜡法是中国传统青铜铸造工艺,是非物质文化遗产。     

静怡轩的建筑渊源及其复原设计

静怡轩是紫禁城建福宫花园中一座建于乾隆七年(1742年)的建筑,1923年毁于火。作者通过对大量文献、实物资料的研究,结合对建筑基址的考察,阐述了静怡轩的渊源和发展,认为静怡轩仿建于圆明园西峰秀色的含韵斋,圆明园西峰秀色又仿自杭州西峰秀色,而故宫宁寿全宫现存的景福宫则仿自静怡轩。景福宫因此成为今日复原静怡轩的实物依据。综合对景福宫建筑和静怡轩基址中台基、踏跺、柱础的考察,作者认为静怡轩应是一座面阔五间,周围廊,三卷棚勾连搭歇山式屋顶,绿琉璃瓦黄剪边,斗升云交麻叶斗,苏式彩画的建筑。     

Telling small stories: spaces of knowledge and the practice of geography

This article examines how the practice of learning geography, and the arenas in which knowledge-making takes place, can be usefully positioned within changing histories of the discipline. It contends that networks of action – understood through the intersection of social sites, subjects and sources – present a conceptual framework and narrative focus for the re-consideration of specific episodes from geography's past. The interventions made here are informed and illustrated by a 'small story' about the doing of geography. Based on different personal accounts, the story revives a series of events, encounters, dialogues and images dating back to the winter of 1951 at Glenmore Lodge, Scotland. This educational institution in the Cairngorm mountains offered children from urban areas the opportunity to learn field studies and the skills of 'outdoor citizenship'. Initially, the focus falls on Margaret Jack, a 14-year-old field-course participant. Her learning experiences are traced through personal letters, a diary and a field journal dating from that time, and her recent recollections of this event. Margaret's account dovetails with the story of her field studies instructor, Robin Murray. Robin's role is traced through his learning experiences as a geography undergraduate at Aberdeen University, and the recent recollections of Catriona Murray, his wife.     

Studies on amerindian dogs, 1: Carbon isotopes in relation to maize in the diet of domestic dogs from early Peru and Ecuador

Work initiated purely as a dating project in support of a craniometric and morphological investigation of domestic dogs from early Peru has proved to have much wider implications. The stable carbon isotoperatios (¹³C/¹²C) of hair samples from ten dogs show that maize formed a significant part of their diet. Radiocarbon dates for these remains have confirmed that they belong to the period well after the cultivation of maize was first established. Stable carbon isotope measurements can thus be used to test for the presence of maize as a dietary constituent at earlier sites even where there is otherwise only indirect evidence for its cultivation. Collagen from animal or human bone is a suitable alternative to hair for this purpose and the method has been successfully applied to collagen dating to c. 3000 BC from the Valdivia culture site of Real Alto, Ecuador, as well as to a series of early Peruvian dogs.
