Rock surface luminescence dating of prehistoric rock art from central Iberia

Rock art paintings are notoriously difficult to date numerically. Recently, luminescence dating has been shown to provide reliable rock surface burial ages in various archaeological settings. Here we use the cross-cutting relationship between a fallen rock and two paintings of the Iberian Levantine (older) and Schematic (younger) styles to constrain the age of the paintings by dating the rockfall event using rock surface luminescence dating. Infrared-stimulated luminescence (IRSL) signals as a function of depth into the buried face of the talus border indicate that the IRSL signal measured at 50°C (IR₅₀) was sufficiently reset to a depth of about 1.6 mm prior to burial. An uncorrected IR₅₀ age of 1.6 ± 0.2 ka was calculated for the rockfall event by dividing the surface equivalent dose (D_e) by the total dose rate. This age was corrected using both conventional and field-to-laboratory saturation approaches to yield indistinguishable ages of 2.7 ± 0.5 and 2.9 ± 0.3 ka, respectively. Since the panel with Schematic art was first available to the artist after the rockfall, we conclude the Schematic rock art at Villar del Humo is younger than ~2.9 ka. The Levantine rock art was painted on a panel constrained by the talus boulder before detachment, and so it is likely to be older than ~2.9 ka.     

Facing two seas: Mediterranean and Atlantic contacts in the north-west of Iberia in the first millennium BC

Summary.  Despite the marginality of the region, the Later Bronze Age and Iron Age communities of the north-west of the Iberian Peninsula were engaged in active relationships with both Atlantic and Mediterranean peoples. Unlike other Atlantic regions, the area maintained direct contacts both with Mediterranean sailors and with the communities of the British Isles and north-western France simultaneously. The social relevance of these interactions and the range of imported goods transported varied throughout the first millennium BC. New evidence shows an intense involvement in Mediterranean trade from the fifth century BC onwards, while Atlantic contacts increased from the late second century BC, to reach a climax under Roman rule (first–second centuries AD).     

Knowledge capture and transfer in rock art studies: Results of a questionnaire on rock art decay in Britain

Abstract

Several thousand prehistoric rock art sites are known in Britain, yet the degree of preservation of these engravings remains a poorly researched and undervalued aspect of the historic environment. Our lack of knowledge has severe implications for how we interpret the rock art sites and how we conserve and manage them. The ongoing ‘Fading Rock Art Landscapes’ project aims to address this gap in our knowledge by gathering information on the rate and nature of decay in prehistoric engravings. As part of the project, a questionnaire was distributed to a number of individuals who, for up to thirty years, have been visiting and recording rock art and who have a detailed knowledge of the sites, how they have changed over time and the types of threat to which they are exposed. In particular, the questionnaire aimed to capture individuals' perceptions of how three groups of agents (physical/chemical, animal, human) influenced the degradation of the engravings. The synthesized results reveal common perceptions of a duality in the rate and nature of decay, with a slow background level of erosion caused by physical and chemical agents, over which is superimposed a rapid, variable degradation from the impact of humans and animals.     

Face images in Lower Angara rock art

The Lower Angara rock art database includes relatively complete information on 42 petroglyphic sites with 155 representations of anthropomorphic faces. The classification of these images and their chronology, assessed on various grounds, suggests that they are roughly contemporaneous and are associated with Okunev art of the Late Neolithic and Early Bronze Age (3rd – 2nd millennia BC). Having originated in the Stone Age, the tradition of depicting anthropomorphic faces was practiced by the taiga tribes of the Lower Angara until recent centuries.     

Expressions of fertility in the rock art of Bantu-speaking agriculturists

This paper presents an overview of the Late White rock paintings of south-central and southern Africa. It is argued that the most recent paintings were produced by matrilineal or bilateral Bantu-speaking agriculturists, although links with earlier hunter-gatherer groups are also implied. It is noted that certain motifs reoccur over great geographical distances. Ethnographic data are used in order to suggest a possible meaning for these motifs and for the paintings in general. It is argued that many of these paintings embody conceptual associations linking them to fertility. A general outline of the most obvious associations is presented, and a plea is made for detailed regional surveys in order to explain temporal and spatial differences.

Résumé Cet article présente une vue d'ensemble sur les peintures rupestres Late White d'Afrique australe et du sud de l'Afrique centrale. Il défend l'idée que les peintures les plus récentes ont été produites par des agriculteurs matrilinéaires ou bilatéraux parlant le bantou, tout en supposant des rapports avec des groupes plus anciens vivant de la chasse et de la cueillette. On remarque que certains motifs réapparaissent à de grandes distances géographiques. L'article s'appuie sur des données ethnographiques pour suggérer une signification possible à ces motifs ainsi qu'aux peintures en général. Il démontre que nombreuses de ces peintures représentent des associations conceptuelles les associant à la fertilité. Un aperçu général des associations les plus évidentes est présenté et les auteurs demandent que des études régionales détaillées soient effectuées afin d'expliquer les différences temporelles et spatiales.

     

Uranium-series dating rock art in East Timor

At many sites throughout the world rock art paintings have been covered by naturally deposited calcite laminations, which we demonstrate can be individually dated by recently improved uranium-series methods. Here we report the application of multi-collector inductively coupled plasma mass spectrometry to measure the ages for carbonate coatings that bracket red pigment at Lene Hara cave, East Timor, which could be evidence of human painting. These analyses establish the feasibility of dating milligram samples of finely layered calcite deposits associated with archaeological evidence of human occupation. In addition to confirming an age of less then 6300 years for the visible red paintings on the carbonate surface we also report a substantially older age of 24,000 to 29,300 years for a similar, older red pigment lamination providing possible evidence for an earlier painting episode.     

Boats in the rock art of Kanozero and Northern Europe

A comparative analysis of boats depicted in the rock art of Lake Kanozero and Northern Europe suggests that they refer to the same type, which was common in northern cultures and was characterized by a protruding straight keel, an oblique sternpost, and a stem post decorated with an elk head. The design apparently consisted of a broad keel plank to which the sides, bow, and stern were attached. In boats represented at Kanozero, this plank protrudes forward, beyond the nose, and backward, beyond the stern.     

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.

Almulihiah: a rock art site in the Hail region,Saudi Arabia

This paper discusses the rock art site of Almulihiah in north Saudi Arabia. The site consists of many carved rock panels of human and animal figures. The drawings depict camels (22%), ibex (10%) and ostrich (8%), although other animals such as goats, lizards and oryx are also present. An attempt is made to date the site by comparing it with other petroglyph sites in the country. The paper concludes with a discussion of the drawing styles present.     

贺兰口岩画风化病害机理

贺兰山岩画在世界岩画中占有重要的地位,由于自然环境因素的长期作用,贺兰山岩画遭受到了严重的破坏,若不尽快采取有效措施,这些珍贵的历史文物将不复存在。但是,截至目前关于贺兰山岩画风化机理的研究甚少,从而严重制约了对其风化机理准确地、有效地科学认识。为此,以贺兰口岩画为研究对象,在风化现状调查的基础上,对其保存环境的温度、湿度、大风及沙尘天气等数据进行统计分析,利用X射线衍射仪、扫描电子显微镜等测试手段,并结合冻融实验和风洞试验进行风化病害机理研究。研究发现,贺兰口岩画以长石杂砂岩为主,引起其风化的因素有温度、湿度、风沙等。其中,温度变化和风沙剥蚀为主要病害因素。该研究有望为全面了解岩画风化机理以及其后续保护工作的实施提供理论基础。     

Latest developments in rock art recording: towards an integral documentation of Levantine rock art sites combining 2D and 3D recording techniques

This paper presents a further step in the integral documentation of prehistoric rock art, combining 2D and 3D digital recording techniques. Image processing and digital enhancement techniques are an invaluable aid to obtain high quality and accurate 2D recordings, especially when working with faint motifs or complex superimpositions. But what constitutes a real breakthrough is the possibility of combining 2D digital tracings with metric 3D models, providing a whole set of metric outputs that improve our understanding of the motifs in their context and, at the same time, can be used to deliver accurate metric reproductions.     

Socioreligious context and rock art in east-central California

Interpretations of rock art typically focus on the symbolic meaning of the art, treating the paintings and engravings implicitly as passive iconographic texts. Rock art, however, is the product of active ritual and ceremony. As such it played an important role in the socioreligious lives of its creators and users. Here I provide a study of the socioreligious contexts of the pictographs and petroglyphs of eastern California, North America, emphasizing the painted art of the Tubatulabal and Coso Shoshone territories and the petroglyphs of the Coso region and using only archaeological data. This requires, first, establishing the chronological placement of this art. Based on a variety of lines of evidence the pictographs and some of the petroglyphs are argued to be historic in age. An ethnography of communications model is then used to provide a conceptual basis for investigating socioreligious contexts and ritual functions of the art. Message content is studied using a factor analysis of painted motif types and an examination of the distribution of sites predominated by certain factors. Two motif complexes, or message content groups, are identified: a Tubatulabal ritual community, employing geometric designs, and a Coso Shoshone community, exhibiting a predominance of representational pictographs. Analysis of message form, channels, settings, and inferred ritual participants suggests that Tubatulabal art resulted from community rituals, in which all the inhabitants of a hamlet would have directly or indirectly participated. Knowledge of the rules for creating and interpreting the parietal art would have been common to all in the community. In contrast, pictographs of the Coso Shoshone were the result of private rituals, with limited numbers of participants and witnesses. The message communicated in the ritual and the painted art would have necessarily been arcane, and few in the community at large may have even known of the creation of this rock art. The Coso petroglyphs, also created by the Coso Shoshone but apparently by a different ritual community within the population, had a different set of rules for ritual actions and symbolic interpretation. The ceremonies creating the engravings were commonplace, yet logically were conducted in private or with few participants, suggesting that the knowledge concerning the means for undertaking and interpreting this type of ritual was widely known throughout the population.
