Prehistoric burnt mound archaeology in Ireland

It is apparent from the widespread distribution of burnt mounds that Ireland was the most prolific user of pyrolithic technology in Bronze Age Europe. Even though burnt mounds are the most common prehistoric site type in Ireland, they have not received the same level of research as other prehistoric sites. This is primarily due to the paucity of artefact finds and the unspectacular nature of the archaeological remains, compounded by the absence of an appropriate research framework. Due to the widespread use of the technology and the various applications of hot water, narratives related to these sites have revolved around discussions of age and function. This has resulted in a generalised classification, where the term ‘fulacht fia’ covers several site types that have similar features but differing functions and age. The study presents a re-evaluation of fulachtaí fia in light of some 1000 sites excavated in Ireland. This is the most comprehensive study undertaken on the use of pyrolithic technology in prehistoric Ireland, dealing with different aspects of site function, chronology, social role and cultural context. A number of key areas have been identified in relation to our understanding of these sites. Previous investigations of burnt mounds have provided little information on the temporality of individual sites. It has been established that appropriate sampling strategies can provide important information about the formation of individual sites, their relationships to each other and to other monuments in the same cultural landscape. The evidence suggests that considerable caution should be exercised with regard to certain single radiometric dates from burnt stone deposits, based on the degree of certainty of the dated sample and its association with pyrolithic activity. Previously regarded as Bronze Age in date, there are now numerous examples of pyrolithic-type processes in earlier contexts, with the origins of the water-boiling phenomenon now considered to be Early Neolithic. A review of recent excavation evidence provides new insights into the use of pyrolithic technology for cooking. This is based on the discovery of faunal remains at several sites, combined with insights gained through experimental studies. The model proposed here is of open-air communal feasting and food sharing hosted by small family groups, as a medium for social bonding and the construction of community. It is also argued that if cooking was the primary activity taken place at these sites, this should not be viewed as a mundane functional activity, but rather one that actively contributed to the constitution of social relations. The formality of the technology is also supported by the presence of possible specialised structures, some of which were used for cooking/feasting while others were for ritualised sweat-bathing. The duration and frequency of activities associated with burnt mounds and the opportunities they provided for social interaction suggest that these sites contributed some familiar frames of reference to contemporary discourse.

A tentative determination of upwelling influence on the paleo-surficial marine water reservoir effect in southeastern Brazil.

Previous work has suggested that seasonal and inter-annual upwelling of deep, cold, radiocarbon depleted waters from the South Atlantic has caused variations in the reservoir effect (R) through time along the southern coast of Brazil. This work aims to examine the possible upwelling influence on the paleo-reservoir age of Brazilian surficial coastal waters based on paired terrestrial/marine samples obtained from archaeological remains. On the Brazilian coast there are hundreds of shell-middens built up by an ancient culture that lived between 6500 to 1500 years ago, but there are few located on open coast with a known upwelling influence. Three archaeological sites located in a large headland in Arraial do Cabo and Ilha de Cabo Frio, southeastern coast of Brazil with open ocean conditions and a well-known strong and large upwelling of the Malvinas/Falkland current were chosen for this study. The 14C age differences between carbonized seed and marine samples varied from 281 ± 44 to 1083 ± 51 14C yr. There are also significant age differences between carbonized seed samples (977 14C yr) and marine samples (200 and 228 14C yr) from the same archaeological layer that cannot be explained by a reservoir effect or an old-wood effect for charcoal. Therefore the present data from the southeastern Brazilian coast are inconclusive for identifying an upwelling effect on R. To do so it would be necessary to more precisely define the present-pre-bomb R in upwelling regions and to analyze paired marine/terrestrial samples that are contemporaneous beyond doubt.

Arqueologia, património e museus na Câmara Municipal de Almeida

Este relatório apresenta as atividades desenvolvidas ao longo do estágio curricular na Câmara Municipal de Almeida, como componente não letiva de formação no Mestrado de Arqueologia da Faculdade de Ciências Sociais e Humanas da Universidade Nova de Lisboa. O estágio teve como principal objetivo a elaboração da carta arqueológica do território das freguesias da Amoreira, Parada e Cabreira, uma parcela do concelho de Almeida. A carta foi elaborada a partir de evidências arqueológicas identificadas em prospeções, de análises da toponímia, da topografia, cartografia, fotografias aéreas e fontes orais do território almeidense. Paralelamente, e no quadro do Museu Histórico-Militar de Almeida, realizou-se um trabalho de organização da reserva arqueológica do município, através da inventariação de todo o espólio arqueológico existente e a elaboração de uma proposta preliminar de conservação preventiva do depósito museal, criando deste modo condições para a receção de novas coleções arqueológicas.

Le Sylvicole inférieur au Méganticois : le cas du site Nepress (BiEr-21)

La découverte du site Nepress (BiEr-21) en 2004 et les saisons de fouilles subséquentes ont permis de découvrir de nombreux vestiges archéologiques. Ce mémoire a donc pour objectif de déterminer l’identité culturelle des occupants qui ont fréquenté le site, en prenant en considération les activités rituelles et la stratégie d’approvisionnement en matière lithique. Pour y parvenir, une analyse morpho-métrique de l’assemblage lithique a été effectuée. La distribution intra-site des artéfacts a également été prise en considération lors de l’analyse. Une séquence chronologique du Nord-Est américain remontant au Sylvicole inférieur est présentée dans ce mémoire. Une période d’occupation semble dominer sur le site Nepress, soit le Sylvicole inférieur. Cette manifestation est caractérisée par la présence d’artéfacts diagnostiques de la culture Meadowood. Ces objets sont un grattoir triangulaire bifacial Meadowood, ainsi qu’une imitation de pointe de type box-base.

L’occupation amérindienne tardive du site Rioux (DaEi-19), île Verte : iroquoienne ou algonquienne?

Ce projet de recherche a comme objectif général de déterminer l’identité culturelle des occupants amérindiens qui se sont établis sur le site Rioux (DaEi-19), île Verte, au cours du Sylvicole supérieur tardif. Plusieurs groupes culturels sont reconnus pour avoir transité dans la région de l’estuaire du Saint-Laurent pendant cette période, dont les Iroquoiens du Saint-Laurent, les Malécites, les Mi’kmaq et les Innus (Montagnais). Il est depuis longtemps accepté que les Stadaconiens se rendaient régulièrement dans l’estuaire et le golfe pour y exploiter les ressources marines et y faire la guerre. L’influence de ce groupe sur les Algonquiens de la région, et vice versa, fait encore l’objet de débats. L’identité culturelle des Amérindiens qui ont occupé les sites à caractère iroquoïde dans l’estuaire est toujours une question délicate, puisque les nombreux échanges ont pu, de part et d’autre, transformer la culture matérielle des différents groupes. La méthodologie préconisée pour répondre à la question de l’identité culturelle est une approche holistique dans laquelle nous avons mis à contribution une foule d’informations provenant de diverses sources archéologiques et ethnohistoriques. Ce projet nous a permis de proposer que de petits groupes iroquoiens du Saint-Laurent se soient arrêtés au site Rioux pour y exploiter intensivement les ressources de la mer au cours du Sylvicole supérieur tardif. Bien que la recherche n’ait pas permis d’établir la présence d’un groupe algonquien sur place, l’influence algonquienne se fait toutefois sentir dans les matières premières utilisées sur le site. Ceci laisse croire que les Iroquoiens du site Rioux, et de la Côte-Sud en général, n’étaient pas intrusifs à la région et qu’ils participaient à un important réseau d’échange avec les Algonquiens des provinces maritimes. Notre projet de recherche nous a aussi permis de constater les limites de notre méthodologie et de critiquer l’approche archéologique classique basée essentiellement sur l’identification stylistique, la typologie et l’identification macroscopique.

Vegetation development and human occupation in the Damascus region of southwestern Syria from the Late Pleistocene to Holocene

Rockshelter Baaz in the Damascus region of Syria provided a variety of botanical remains from the Late Pleistocene and Early Holocene period. These remains provide new information about the vegetation evolution in this region. The earliest occupational levels correspond with a moisture peak during the Late Pleistocene, between ca. 34-32 kyr b.p., when pine expanded. The next occupations took place during extreme arid conditions, ca. 23-21 kyr b.p., and probably during the Last Glacial Maximum when a steppe vegetation was established. The occupation level of the Younger Dryas, represented by Natufian remains, suggests that the area had been covered by almond-pistachio steppe, similar to later periods of the Early Holocene, and was probably located just outside the range of dense wild cereal stands. There is no drastic impact of the Younger Dryas visible on the vegetation in the botanical remains. The lack of fruits and seeds at Baaz indicates that the site was more likely to have been a temporary hunting post rather than a plant processing site for much of its history. It is ideally suited to this purpose because of its location over the Jaba'deen Pass and the associated springs. However, archaeological remains from the Natufian period, suggest that the site was more permanently occupied during this time.

Sutton Common (South Yorkshire): a monument at risk in England’s wetlands

The work on the Iron Age site at Sutton Common, South Yorkshire, UK, has provided both inspiration and a testing ground for the development of English Heritage's strategy for wetlands. This paper concentrates on the non-technical aspects of the developing conservation management of the site, which includes in situ preservation of selected waterlogged remains, and summarises the main results of the Monuments at Risk in England's Wetlands project, the new strategy for which it formed the basis

Crusader churches in the Latin East : expressions of medieval theology

The Latin invaders of the Eastern Mediterranean in the 12th-14th Centuries were on a mission to retrieve and protect the Christian Holy Land from Muslim occupation. They encountered a consistent, Eastern approach to the architectural expression of the Christian faith which the physical remains of their churches show they adopted. Previously, I have shown how it can be deduced from the archaeological remains of churches from the 4th-6th C that early church architecture was influenced by the theological ideas of the period. This paper argues that the Eastern approach to church architecture as adopted by the Crusaders was compatible with the medieval European theological context and can be seen as a legitimate expression of medieval theology.

In the Syrian taste : crusader churches in the Latin East as architectural expressions of orthodoxy

This paper explores how the architectural expression of orthodoxy in the Eastern churches was transferred to Europe before the Crusades and then reinforced through the Crusaders’ adoption of the triple-apsed east end “in the Syrian Taste” in the Holy Land. Previously, I have shown how it can be deduced from the archaeological remains of churches from the 4th-6th C that early church architecture was influenced by the theological ideas of the
period. It is proposed that the Eastern orthodox approach to church
architecture as adopted by the Crusaders paralleled the evolution of medieval theology in Europe and can be seen as its legitimate expression.

Metodologia geofísica aplicada ao estudo arqueológico dos sítios Bittencourt e Jambuaçu, Estado do Pará

Medidas magnéticas, de radiação gama e eletromagnéticas com o Radar de Penetração no Solo (GPR) foram realizadas em dois sítios arqueológicos localizados nas proximidades de uma área destinada a construção de um mineroduto. O objetivo das medidas foi identificar locais para escavação arqueológica visando a descoberta de remanescentes de habitantes que povoaram a região em tempos pretéritos, auxiliando nos estudos para recompor a sua história. As medidas magnéticas evidenciaram anomalias que levaram a descoberta de uma grande quantidade de fragmentos cerâmicos e de outros artefatos. As medidas de radiação gama permitiram a discriminação entre solo arenoso e argiloso, o que representa um resultado importante, pois o solo arenoso geralmente é correlacionado a camada de ocupação arqueológica onde são encontrados os remanescentes. O Radar de Penetração no Solo confirmou as anomalias magnéticas e mostrou outras feições anômalas não relacionadas aos remanescentes arqueológicos.

Métodos geofísicos aplicados à arqueologia no Estado do Pará

Este trabalho constitui uma primeira tentativa de aplicação de métodos geofísicos à pesquisa de sítios arqueológicos no Brasil. Esses métodos foram usados com a finalidade de detetar feições arqueológicas no subsolo, em dois sítios arqueológicos no estado do Pará: o sítio PA-SA-4, da fase arqueológica Areão e o sítio Ilha dos Bichos da fase Marajoara. No PA-SA-4, foi empregado o método magnético, enquanto que na Ilha dos Bichos, além do método magnético, foi usado o eletro-resistivo. O método eletro-resistivo possibilitou não só a determinação da camada de ocupação, pois esta camada se comporta geoeletricamente diferente das camadas que compõem as formações geológicas da região, como também permitiu detetar camadas compactas de argila, planas e horizontais, de origem arqueológica, situadas no lado oriental da Ilha dos Bichos. O método magnético levou à deteção de antigos locais de queima, devido a magnetização termo-remanente adquirida pelas argilas no processo de aquecimento/resfriamento, permitindo a descoberta de antigos fornos, bem como de uma urna funerária sob espessa camada de argila queimada.

Investigation of the genetic diversity of domestic Capra hircus breeds reared within an early goat domestication area in Iran

Background: Iran is an area of particular interest for investigating goat diversity. Archaeological remains indicate early goat domestication (about 10 000 years ago) in the Iranian Zagros Mountains as well as in the high Euphrates valley and southeastern Anatolia. In addition, mitochondrial DNA data of domestic goats and wild ancestors (C. aegagrusor bezoar) suggest a pre-domestication management of wild populations in southern Zagros and central Iranian Plateau. In this study genetic diversity was assessed in seven Iranian native goat breeds, namely Markhoz, Najdi, Taleshi, Khalkhali, Naini, native Abadeh and Turki-Ghashghaei. A total of 317 animals were characterized using 14 microsatellite loci. Two Pakistani goat populations, Pahari and Teddy, were genotyped for comparison.Results: Iranian goats possess a remarkable genetic diversity (average expected heterozygosity of 0.671 across loci, 10.7 alleles per locus) mainly accounted for by the within-breed component (G(ST) = 5.9%). Positive and highly significant F-IS values in the Naini, Turki-Ghashghaei, Abadeh and Markhoz breeds indicate some level of inbreeding in these populations. Multivariate analyses cluster Iranian goats into northern, central and western groups, with the western breeds relatively distinct from the others. Pakistani breeds show some relationship with Iranian populations, even if their position is not consistent across analyses. Gene flow was higher within regions (west, north, central) compared to between regions but particularly low between the western and the other two regions, probably due to the isolating topography of the Zagros mountain range. The Turki-Ghashghaei, Najdi and Abadeh breeds are reared in geographic areas where mtDNA provided evidence of early domestication. These breeds are highly variable, located on basal short branches in the neighbor-joining tree, close to the origin of the principal component analysis plot and, although highly admixed, they are quite distinct from those reared on the western side of the Zagros mountain range.Conclusions: These observations call for further investigation of the nuclear DNA diversity of these breeds within a much wider geographic context to confirm or re-discuss the current hypothesis (based on maternal lineage data) of an almost exclusive contribution of the eastern Anatolian bezoar to the domestic goat gene pool.
