Temperature,compression and fragmentation: an experimental analysis to assess the impact of taphonomic processes on charcoal preservation

This paper explores how mechanical properties of different South Asian tree taxa might influence charred wood fragmentation and the composition of charcoal assemblages retrieved from archaeological contexts. The dataset is composed of selected plant species that were collected in Gujarat (Northern India) in September 2007 as part of the North Gujarat Archaeological Project. The taxa analysed represent the most common wood species found in the arid thorn scrubland formation in South Asia and are among the most abundant identified in Neolithic and Chalcolithic archaeological sites in this area. The specimens have been measured and subsequently charred at three different temperatures, under constant conditions. Afterwards, their resistance to compression has been measured on two planes, parallel and perpendicular to the direction of fibres, using a Hounsfield 5-kN machine. The tests were performed in order to understand the different response to compressive stress of wood that has been subject to a range of thermal degradations. The standardised treatment applied to the samples has permitted the comparison of results and the delineation of simple correlations and divergences among the species analysed. Furthermore, the utilisation of a relatively simple operating protocol easily allows the addition of further data in the future. The applied protocol was specifically designed to answer archaeological questions. Therefore, even though from a material science point of view some of the measurements were not taken according to the prevailing standard procedures, it offers valuable data for anthracological research applied to archaeology in arid zones.     

新传统的兴起——晚明观念变迁与生活方式

Ethics based on Confucian moral virtues and guides as core values have long formed the “old tradition” in determining the direction of China’s social development. Changes of urban residents’ values and corresponding changes in life styles in late Ming Dynasty demonstrated the emergence of a new cultural tradition that advocated for human freedom and the development of individuality, material enjoyment and pleasures in life, and questioned and critiqued Confucian moral virtues and guides. Although such a cultural tradition had not yet matured, its humanist values made deep imprints in that period. This tradition survived despite of the successions of dynasties and vicissitudes of the ages, although from time to time it became so weak as on the verge of extinction. It was this continuous and unceasing cultural progress that later laid the primitive but essential cultural foundation for the start of China’s efforts to achieve modernization after the middle of the 19^th century.     

One world,one place

Este artículo rastrea la historia del World Archaeological Congress desde una perspectiva sudafricana-una posición estratégica apropiada, dado que el WAC se formó entorno al tema del apartheid y la relación entre el estudio del pasado y la política del presente. Mientras el apartheid fue una cuestión bien definida, los asuntos que el WAC ha tenido que afrontar con posterioridad no han resultado tan sencillos, e incluso en ocasiones han llevado a la incertidumbre. El concepto de Una Arqueología Mundial que el WAC adopta puede ser visto como una serie continua de meditaciones ligadas con una propuesta fundacional. Sin embargo este mundo ha cambiado. Las nuevas tecnologías de información y comunicación suponen el fin de las distancias que en el pasado supusieron un factor limitador para los movimientos mundiales progresistas. En pocos a?os, la red de banda ancha tendrá un coste bastante inferior en todas las ciudades del mundo. Las organizaciones mundiales que luchan contra intereses establecidos serán redes flexibles que se organizarán entorno a cuestiones locales, compartiendo al mismo tiempo la información y los recursos a nivel global. De este modo se abren grandes oportunidades para los movimientos mundiales que enlazan, a una y al mismo tiempo, las complejidades de las circunstancias locales y las oportunidades de las alianzas globales.

Résumé Le r?le de l'apartheid et de la localisation de Cape Town sont des éléments utilisés dans le survol du développement du Congrès Mondial de l'Archéologie et du mouvement One World Archaeology depuis 1986. à l'époque un boycott académique a empêché la participation des Sud-africains au congrès de Southampton durant lequel fut formaliser le CMA. Le terme un monde, une place, caractérise la proposition d'adopter une nouvelle approche et l'opportunité de repositionner le mouvement One World Archaeology. L'approche un monde, une places'oriente sur le concept de place, de sites locaux d'engagements et de connections entre la question de l'identité, le patrimoine culturel, l'interprétation historique et les droits humains. Un accès élargis aux nouvelles technologies de communication peut faciliter cette approche et offrir le potentiel de se préoccuper de la diversité des localisations et rendre possible le développement d'un réseau de communication stratégique d'une ≪archéologie engagée.

     

Archaeological ethnography: Conversations around Kruger National Park

Este artículo esboza las posibilidades para una práctica mixta, a la que yo denomino etnografía arqueológica, que enlaza la arqueología y antropología sociocultural. Mi trabajo de campo se ha realizado en los límites del Parque Nacional Kruger con individuos de la comunidad de Malatji, y también con ecologistas sociales, guardas del parque, intérpretes y agentes del patrimonio que trabajan en el parque nacional. La investigación contribuye y evalúa críticamente el centralísmo del patrimonio arqueológico de Sudáfrica y sus múltiples papeles en la formulación de nuevas subjetividades en la nación cosmopolita y postcolonial.

Résumé Cet article illustre la possibilité d'utiliser l'ethnographie archéologique comme pratique hybride permenttant de faire le pont entre l'archéologie et l'anthropologie socioculturelle. Mon travail de terrain se déroule à la limite du Parc National Kruger avec des individus de la communauté Malatji et aussi des spécialistes en écologie sociale, des agents de la conservation, des guides interprètes et des représentants du patrimoine employés du parc national. Cette recherche entend contribuer et faire une évaluation critique de la centralité du patrimoine archéologique en Afrique du sud et de ses r?les multiples dans la formation d'une nouvelle subjectivité dans la nation cosmopolite postcoloniale.

     

Source of ore fluids at the Kalahari Goldridge deposit, Kraaipan greenstone belt, South Africa: evidence from Sr, C and O isotope signatures in carbonates

The Kalahari Goldridge deposit is located in the Archaean Kraaipan greenstone belt in the north-west province of South Africa. Gold mineralization in this deposit is hosted within banded iron formation which is flanked by a mafic schist in the footwall and clastic metasedimentary units in the hanging wall. Data from carbonate minerals from mineralized veins and bulk rock from the A and D zone ore bodies have helped to define the ultimate origin of the ore-forming fluids and their migration history. Carbon isotope ratios of carbonates from both the A and D zone ore bodies have tight clustering from −7.6 to −5.3‰ that indicates a unique origin for the ore-forming fluids associated with the mineralization at Kalahari Goldridge. The δ¹⁸O values of the carbonates have been influenced by temperature gradients and variable degrees of fluid–rock interaction promoting oxygen isotope exchange between ore fluid and host rocks. Minimum ⁸⁷Sr/⁸⁶Sr ratio values of 0.70354 in mineralized veins are most consistent with ore-forming fluids being relatively pristine with a mantle origin. Strontium and the corresponding ore-forming fluids were most likely derived from mantle-derived magmatic rocks probably represented by the meta-basaltic rocks that underlie the ferruginous package in the Kraaipan greenstone belt. Strontium isotopic composition of vein carbonates show considerable variation in ⁸⁷Sr/⁸⁶Sr ratios ranging from 0.70354 to 0.73914. This is consistent with an ore fluid composition that has been modified by the addition of radiogenic Sr possibly during passage of fluid through siliciclastic country rock concomitant with the observed hydrothermal alteration.

The Gothic and the Gaelic: Exploring the Place of Castles in Ireland’s Celtic Revival

This paper examines the conflict in early nineteenth century Ireland that emerged between the way castles were portrayed in academia on the one hand and romantic literature on the other. Focusing on a key text of the Celtic Revival, Sydney Owensons The Wild Irish Girl, the paper explores how this novel (with its strong gothic influences) established a lens through which Gaelic Ireland could be understood and how this in turn affected the representation of castles. The second part of the paper ties these themes into an analysis of the relationship between architecture, literature and identity in the occupation of Leap Castle, Co. Offaly during the changing political climate of nineteenth and early twentieth century Ireland.     

Wild Cattle: Red Deer in the Religious Texts,Iconography, and Archaeology of Early Medieval Ireland

Humans use animals as a means of creating and manipulating relationships with other human beings. This process occurs both through the use of animals for food or raw materials and through the use of animals as literary and artistic symbols. Cervus elaphus is Irelands only indigenous deer species. It is also unique in being the only native Irish, wild animal to appear frequently in medieval texts, iconography, and archaeological deposits. This paper brings together diversesources of information to illuminate how early medieval monasteries used reddeer to establish an identity for themselves and to conceptualize socioeconomic relationships with others.     

Rock Art Between Preservation,Research and Sustainable Development—a Perspective from Southern Ethiopia

This paper focuses on southern Ethiopia, along the outer rim of the Rift Valley and not far from the Kenyan border, in an area forming part of a larger region known as a cradle of humankind. However, it also hosts a diverse Holocene rock art heritage, which is still underestimated and underdocumented. Paintings and engravings are widespread in the region, both in rock shelters and open-air sites, often located in remote areas currently inhabited by communities belonging to different ethnic groups. The aim of this paper is to present the first results of a new project in the area around Yabelo, within the broader framework of rock art research in East Africa, integrating archaeological research, preservation and heritage management with a relevant involvement of local communities. The outstanding cultural importance of these contexts offers new prospects for both scholarly research and sustainable development. The recording and study of the artworks is underway, using digital technologies that guarantee a high standard of accuracy of the documentation and non-invasive recording methods. This provides important insights for reconstructing cultural dynamics in the area between the final Pleistocene and onset of the Holocene. Moreover, the focus on rock art makes it possible to enhance local knowledge, increasing the awareness of local communities, with a significant impact on the preservation of this fragile heritage and the development of local, sustainable tourism projects. Differently from other archaeological features, rock art can have a more immediate attractiveness for contemporary observers, in terms of the apparent immediacy of the images and their emotional impact, raising awareness of cultural heritage and fostering major involvement in its preservation.
