The Production and Deposition of the Guisborough Helmet

In September 1878 the British Museum received a donation of a folded metal plate which had been embossed and gilded. Restoration of the object revealed that the folded plate was in fact the outer casing of a Roman copper alloy cavalry sports type helmet which dates to the late second or third century AD. The story of what became known as the Guisborough helmet began 14 years earlier in what was then the North Riding of Yorkshire when workers employed by the Cleveland Railway Company discovered a ‘very curious plate of metal’ during road construction. It appears that the helmet was deliberately prepared for deposition and buried at a depth of c30 cm close to a stream. Examination by the authors suggests that this was a high value item that had been repaired many times. Experimental evidence suggests that the decoration alone required approximately 16 h to fashion.     

A Portrait of a Helmet: A Funerary Helmet from the Northern Netherlands

This paper describes a seventeeth-century helmet, which was found in a church in the Frisian village of Schettens. Not only the type, but also the context in which this helmet was found, made the find exceptional. The presence of tombstones in the church made it possible to trace the object to a Frisian colonel from the Dutch States Army. What makes the helmet even more special, is the fact that it was prominently depicted on the tombstone of the deceased Frisian colonel. The find of the helmet and its ‘portrait’ on the tombstone are unique for the northern Netherlands. It gives cause for further study of the Dutch funeral tradition, in which elements of armour played an important role. In this regard, it is very interesting to draw a comparison with the same tradition in England.     

基于图像和惯性的头盔组合跟踪原理

不同体制的头盔跟踪定位技术单独使用时都存在一定的原理性性能制约,提高跟踪定位技术整体性能的有效途径是采用组合跟踪。目前综合性能较好的是图像式头盔跟踪,图像式跟踪技术精度高,输出数据平稳,稳定性好,但其缺点是头盔活动范围受制于CCD摄像机视场及头盔大角度转动时头盔本身对CCD摄像机视角的遮挡。惯性跟踪不需要任何外来信息也不向外辐射任何信息,可在任何介质和任何环境条件下实现360°全范围头部跟踪,但其定位精度随时间下降。提出的基于图像和惯性的头盔组合跟踪技术充分利用图像跟踪精度高、长期稳定性好及惯性定位跟踪范围广、跟踪系统简单的优点,达到单个跟踪定位体制不具备的综合性能。     

The Blind Basinet: A New Interpretation of Royal Armouries IV.2

For many years a curiosity in the collection of the Royal Armouries, IV.2, or the ‘Blind Basinet’, is a fascinating example of an early 16th century great basinet not so much for what is present but for what is not. The lack of any means of seeing out of the helmet has led to a number of traditions regarding its provenance and purpose. A detailed examination of the helmet’s interior, as well as comparison with some other contemporary pieces, shows that it is an unfinished piece of armour. It was left at the stage where the sights and breaths would have been pierced, but they were left unfinished until some later modifications created a display piece, one which can still be seen at the Royal Armouries in Leeds.

Conserving a Late Eighteenth–Early Nineteenth Century Indian Helmet: A Technical Study

This paper describes the treatment of a distinctive late eighteenth/early nineteenth-century helmet from Gwalior in India known as a kolah khud or top. The fine mail aventail of the helmet, comprised of butted rings of iron or steel and brass, had fallen into a severe state of disrepair and was at risk of further deterioration without interventive conservation. The processes of replicating new mail rings and integrating these into the original structure as well as cleaning the helmet are discussed together with an analysis of the ethical implications of such actions.     

Gill — A Family of Sword Cutlers

Abstract

Amongst the armour in the collection of the British Museum is a kettle-hat (Object Number: P&;E 1856,0701·2243) that was found in London during the second quarter of the nineteenth century. In January 2010, the kettle-hat was conserved before its loan to the Royal Armouries Museum for display at the Tower of London. New findings that occurred during conservation led to the most in-depth technical examination and analysis of this relatively unknown helmet since its discovery.

This paper aims to interpret the British Museum’s kettle-hat from art historical perspectives in order to place it in a wider context. The development of the kettle-hat during the 14th and 15th centuries is described along with the subsequent derivatives of transitional or progressive forms of helmet. Through stylistic comparison and consideration of related evidence it is suggested that the British Museum kettle-hat dates to the late 14th century and is of western European, possibly English, workmanship. Furthermore, although the British Museum helmet has much in common with typical forms of kettle-hat, it also has features, such as a short tail-piece, that suggest it may be closely related to some early forms of sallet.

A platform for initial testing of multiple camouflage patterns

The human visual system is still an important factor in military warfare; military personnel receive training on effective search strategies, and camouflage that can effectively conceal objects and personnel is a key component of a successful integrated survivability strategy. Previous methods of camouflage assessment have, amongst others, used psychophysics to generate distinctiveness metrics. However, the population from which the human observers are drawn is often not well defined, or necessarily appropriate. In this experiment we designed a new platform for testing multiple patterns based on a camouflaged object detection task, and investigate whether trained military observers perform better than civilians. We use a two-alternative forced choice paradigm, with participants searching images of woodland for a replica military helmet displaying Olive Green, Multi Terrain Pattern, US Marine Pattern or, as a conspicuous control, UN Peacekeeper Blue. Our data show that there is no difference in detection performance between the two observer groups but that there are clear differences in the effectiveness of the different helmet colour patterns in a temperate woodland environment. We conclude that when tasks involve very short stimulus presentation times, task-specific training has little effect on the success of target detection and thus this paradigm is particularly suitable for robust estimates of camouflage efficacy.     

Late Medieval Lance Use: Mounted Combat and Martial Arts in Western Europe from the 14th to the 16th Century

Despite the lance’s status and the amount of attention the couched lance has received in historiography, study of its martial art has been neglected. The various lance types and techniques used by western European cavalry have only recently begun to receive scholarly attention. Additionally, Medieval European lance use has too often been studied in isolation, without an adequate understanding of the idiosyncratic and asymmetrical dynamics of mounted combat. Although the charge with the couched lance was a valid tactic, it was only one of many. Light and heavy lances were used in one hand or two to trip, block, unhorse, and wrestle. These techniques were governed by the harsh laws of distance, speed, impact, iron, and asymmetry. By utilizing the surviving Fechtbücher and several Peninsular and Near Eastern sources, a brief foray into the diverse techniques of lance use and their purposes has been attempted here.

A Castle in the Air? The Building,Arms, Action and Incident on the Eleventh-Century ‘Castle’ Capital from Westminster Hall

The restoration of Westminster Hall in the 1830s revealed a number of eleventh-century carved capitals, one depicting, as then described, ‘an armed man assailing a castle’. Aided by archaeological evidence from Abinger (Surrey), the ‘castle’ can be convincingly interpreted as a motte-top tower, carried by earth-fast posts, open-sided below and faced above with boards painted to resemble masonry. It is the only known depiction in elevation of a type of tower that is likely, given its simplicity, to have been widely used in the eleventh and twelfth centuries. The assailant, armed with an axe, carrying a round shield and wearing a helmet with nasal, is shown climbing the tower’s external stair at the moment of being despatched or wounded by the defender’s spear. The incident, an individual action rather than a ‘siege’ as such, has many oddities, and may represent a topical event or scene from history or mythology. The story of the Trojan War is suggested as a possible source.

The group includes an exceedingly rare form of helmet of the period, one made in the form of a broad brimmed hat. The article discusses the small group of known examples, and illustrates the closest comparable iron hat from the Scott collection in Glasgow Museums and Art Galleries.     

新疆兵团体育文化特征、价值及体育文化的创新研究

新疆兵团(以下简称"兵团")体育文化的形成植根于军队,发展于屯垦戍边事业,在我国民族体育文化中具有独树一帜的特征和价值;在60年的发展历程中,一直以兵团精神为精神支柱和发展动力,为促进兵团社会政治、经济、文化等事业发展,维护新疆社会稳定发挥了重要作用。近年来,兵团体育文化与城市化快速发展不相适应,仍然保留着"单位体制"、"行政运行"的局面,严重阻碍了兵团体育文化多元化、特色化、社会化的发展,因此,在兵团城市化背景下,体育文化体制、体育物质文化和体育文化内容必须走创新之路,才有发展的生机和活力。
