Post-Roman crop production and processing: Archaeological evidence from Goldthorpe,South Yorkshire

The remains of a ditched field system dating from the late Iron Age to the early post-Roman period, and two associated corn drying ovens (dating to the 5th–6th centuries AD) were revealed during archaeological excavations at Goldthorpe, South Yorkshire. The site was excavated during 2012 and 2013, during which bulk environmental samples were taken in order to retrieve any surviving botanical remains from deposits associated with the corn drying ovens, and other features across the excavated area. Early post-Roman occupation is under-represented in the archaeological record, especially in northern England, as such human activity and subsistence during this period are currently not well understood. This paper combines evidence for the field system, the physical remains of the corn drying ovens and their associated botanical remains to further understand early post-Roman change and continuity in landscape use and crop production and processing practices.     

The evolution of sociopolitical complexity in prehistoric Hawaii: An assessment of the archaeological evidence

The sociopolitical system of late prehistoric Hawaii was among the most complex of any Oceanic chiefdom, as indexed by such characteristics as scale, rate of energy extraction, degree of functional specialization, and political hierarchy. Various anthropologists and archaeologists have advanced models of how this complex sociopolitical system developed out of an earlier Ancestral Polynesian society. Recent advances in Hawaiian archaeology have now begun to provide a wealth of data on the course of prehistoric change in the archipelago over some 1500 years and, thus, provide evidence which can be used to test alternative models of the evolution of sociopolitical complexity. This paper reviews the major alternative models that have been put forward and provides a synopsis of the archaeological evidence relevant to their testing.     

Archaeobotanical evidence of prehistoric maize (Zea mays) consumption at the northern edge of the Great Plains

Analysis of starch granules, phytoliths, and plant macrofossils from archaeological features and carbonized food residue provides important new insight into the extent of prehistoric maize (Zea mays) consumption on the North American Great Plains. These data suggest that consumption of maize, and probably other cultigens, was widespread on the eastern Canadian Prairies between approximately AD 1000 and 1600. Domesticated plants may have been grown locally, acquired through trade, or transported into the region following dispersal of family groups from horticultural villages located elsewhere. However, the lack of strong artifactual evidence of gardening, and the small-scale nature of sites on the eastern Canadian Prairies indicate that local horticulture, if practiced, was non-intensive.     

Quantitative computerized tomography for the diagnosis of osteopenia in prehistoric skeletal remains

In this study, we examine the value of bone density assessed by computed tomography (QCT) of the right tibia in the diagnosis of low bone mass in prehistoric bones. Trabecular bone mass (TBM) was assessed by histomorphometry in undecalcified bone sections of a small part of the proximal epiphysis of the right tibia of 78 prehispanic individuals. Bone density was also assessed in the proximal epiphysis of the right tibia, in an area of cancellous bone immediately adjacent to the wedge which was destined to histomorphometry, with the aid of a Tomoscan 60 TX™ (Philipps Medical System, Eindhoven, The Netherlands) using a phantom of hydroxyapatite included in plastic resin at three known concentrations (50, 100 and 200 mg/cc) and ethanol as fat equivalent. Bone density (as bone hydroxyapatite concentration in milligram per cubic centimeter) was calculated by means of a specific software tool (QCT Bone Mineral Analysis System, Image Analysis, California). We compared bone density assessed with QCT with TBM in these individuals, and also, with the results obtained from a modern control group. We calculated the median TBM of the prehispanic sample and tested the sensitivity, specificity, and overall accuracy of QCT in diagnosing TBM values below the median. We later performed the same analyses on 24 more prehispanic individuals. Both QCT (t = 5.61, p < 0.001) and TBM (t = 3.79, p < 0.001) were significantly lower among the prehispanic individuals than among the control ones. QCT showed a significant relationship with TBM (r = 0.41, p < 0.001). QCT values below 100 mg/cc serve to establish a diagnosis of low TBM values with a sensitivity of 82.1% and a specificity of 41%. In the test group sensitivity was 83.3% and specificity, 50%.     

The archaeobotany of Indian pulses: identification,processing and evidence for cultivation

Abstract

Pulses are a significant component of traditional subsistence in South Asia. Reliable identification criteria for identifying these from archaeological seed remains are reviewed. The botanical evidence relating to the wild progenitors and their distribution, especially of Indian natives (Macrotyloma uniflorum, Vigna radiata, Vigna mungo) is summarised, including new evidence from primary botanical research. The problem of seed size increase in pulses is reviewed through a focused study on Vigna spp., in which it is shown that seed enlargement is delayed by 1–2,000 years after initial cultivation. The taphonomy of archaeological pulses is considered in the context of crop-processing of pulses, in which an important distinction can be drawn between free-threshing and pod-threshing types. The total archaeobotanical record for pulses in South Asia (India and Pakistan) is summarised and key regional differences are highlighted.     

Social agency and the dynamics of prehistoric technology

Technology is not only the material means of making artifacts, but a dynamic cultural phenomenon embedded in social action, worldviews, and social reproduction. This paper explores the theoretical foundations for an anthropology of technology that is compatible with this definition. Because of its focus on social agency, practice theory provides an appropriate starting point for a social theory of technology. In addition, three other themes require explicit attention: scale, context, and the materiality of technology. Four case studies demonstrate how archaeologists are beginning to take technology beyond its material dimensions, and additional questions are proposed stemming from the theoretical issues raised in the paper. The purpose of this essay is to synthesize a diverse set of emerging ideas and approaches to understand better dynamic community-level social processes of prehistoric material culture production.     

A model of prehistoric collecting on the rocky shore

Selective resource exploitation patterns in prehistory are often explained in terms of cultural preference, but this paper argues that a non-cultural explanation based upon zoological models of consumer choice may be equally valid. A model of shell-fishing behaviour concerning the relationship of abundance and yield is developed and used to predict that rocky shore collectors should ignore all factors other than the individual size of shellfish and that, in doing so, they would become progressively selective in their collecting patterns. Data from prehistoric rocky shore shell middens in Palliser Bay, New Zealand, indicates several phases of progressively selective collecting over a period of 600 years and these patterns appear best explicable in terms of the model.     

Modeling the prehistoric arrival of the sweet potato in Polynesia

The sweet potato is a plant native to the Americas, and its pre-historic presence in Polynesia is a long-standing anthropological problem. Here we use computer-driven drift simulations to model the trajectories of vessels and seed pods departing from a segment of coast between Mexico and Chile. The experiments demonstrate that accidental drift voyages could have been the mechanism responsible for the pre-historic introduction of the sweet potato from the Americas to Polynesia. While present results do not relate to the feasibility of a transfer by purposeful navigation, they do indicate that this type of voyaging is not required in order to explain the introduction of the crop into Polynesia. The relatively high probability of occurrence and relatively short crossing times of trips from Northern Chile and Peru into the Marquesas, Tuamotu and Society groups are in agreement with the general consensus that this region encompasses the area of original arrival and subsequent dispersal of the sweet potato in Polynesia.     

Representation and knowledge in the prehistoric rock art of Africa

This study proposes that prehistoric rock art in Africa represents aspects of the natural and social environment which are aesthetically charged, for practical and symbolic reasons, and which are also problematic, in specific ways, for ordinary, untutored perception. Rock art functions as a medium of communication in three principal contexts. It refers to an extended network of ritual acts and beliefs, to out-of-the-ordinary perception and knowledge, and to adaptively significant local information. Rock art is therefore a particular, specialized instrument of the production process. Investigating the study of prehistoric art from art historical, archaeological, and anthropological points of view, the paper examines the ways in which the original contexts of function or meaning might be reconstituted, given the special nature and constraints of graphic representation as a mode of knowledge. Three major traditions of prehistoric rock art in Africa, the Sahara, Nile valley, and southern, are the focus of discussion and source of examples. The paper takes as a general theme the feasibility or possibility of an adequate archaeology of prehistoric knowledge.

Résumé La présente étude propose que l'art rupestre préhistorique en Afrique représente des aspects du milieu naturel et social, exprimés de façon esthétique pour des raisons pratiques et symboliques, et qui présentent aussi des problèmes particuliers face à une perception non instruite. L'art rupestre sert de moyen de communication dans trois contextes principaux: il fait allusion à un réseau compliqué de croyances et d'actes rituels, à une perception et à des connaissances hors de l'ordinaire et à des renseignements locaux affectant l'adaptation. L'art rupestre figure donc comme instrument particulier et spécialisé dans le processus de production. En vérifiant l'étude de l'art préhistorique des points de vue historique, archéologique et anthropologique de l'art, l'article examine les façons selon lesquelles les contextes originaux de la fonction ou la signification pourraient être reconstitués, selon la nature et les contraintes spéciales de la représentation graphique comme genre de connaissance. La discussion se centre sur trois traditions principales d'art rupestre préhistorique, celles du Sahara, de la vallée du Nil et de l'Afrique du Sud, d'où sont aussi tirés les exemples. L'article a pour thème général la possibilité d'une archéologie mieux adaptée à la reconstruction des modes de connaissance préhistorique.

     

Re-establishing an underground climate appropriate for the conservation of the prehistoric paintings and engravings at Lascaux

Abstract

In an earlier issue (CMAS 1 (3), 191-193), we summarized highlights from new statements of ethical practice for archaeologists produced by the Society for American Archaaeology (SAA), the Archaeological Institute of America (AIA) and the American Schools of Oriental Research (ASOR). We now publish a note about the Society for Historical Archaeology from its President, Dr Glenn Farris. In it he draws attention to a statement of the Society's ethical position that was made in 1989.

Since our publication of the earlier note, the question has been raised as to how effective are ‘statements of ethical practice’ in governing conduct. It should be stressed that acceptance of a professional society's statement on ethics is normally a condition of membership in that society. This is the case in a large number of organizations, both national and international, in the area of archaeology, conservation and museums. There is no doubt that Codes of Ethics have a strong impact on professional conduct in these disciplines.     

Holocene vegetation of the Eastern Sahara: charcoal from prehistoric sites

This paper is dedicated to Prof. Dr K. U. Leistikow on the occasion of his 60th birthday.The investigation of 320 charcoal samples from prehistoric sites in the Eastern Sahara furnishes evidence for a fundamental change of vegetation during the early and middle Holocene. Two ecological regions can be distinguished. In Egypt desert formations prevailed, consisting of the same vegetation elements as today though with a wider distribution, while in the Sudan tropical savannas occurred. Around 7000 bp the Sahelian vegetation zones were 500–600 km north of their present range, and 300–400 km around 5700 bp. The Sudanian flora of Fachi-Dogonboulo in Niger, datedca 7000 bp, points to a simultaneous shift of the vegetation zones in the Eastern and in the Central Sahara. With increasing desiccation from 5200 bp onwards, the savanna formations retreated to the south until their present position was reached by 3300 bp.

Résumé L'étude de 320 échantillons de charbons de bois provenants de sites préhistoriques du Sahara Oriental, met en évidence un changement important dans la végétation au cours de l'Holocène ancien et moyen. Deux régions écologiques peuvent être distinguées: en Egypte les formations désertiques étaient prédominantes, comprenant les mêmes éléments qu'aujourd'hui mais avec une plus large extension. A la même époche le Soudan connaissait une végétation de savanes tropicales. Autour de 7000 ans bp, la zone de végétation sahélienne se situait à 500–600 km plus au nord de sa limite actuelle, et vers 5700 ans bp elle était encore à 300–400 km. La flore soudanienne de Fachi-Dogonboulo, Niger, datée de 7000 ans bp, indique un déplacement simultané des zones de végétation au Sahara Oriental et Central. Sous l'effet d'un assèchement croissant à partir de 5200 ans bp, les formations de savane se sont retirées vers le sud, jusqu'à atteindre leur situation actuelle vers 3300 ans bp.
