High‐resolution geospatial surveying techniques provide new insights into rock‐art landscapes at Shuwaymis,Saudi Arabia

Many parts of the Arabian Peninsula contain rock art that has received minimal archaeological attention or has not yet been thoroughly surveyed. In 2001 an extensive rock‐art complex called Shuwaymis, Ha'il Province, Saudi Arabia was brought to the attention of the Saudi General Commission for Tourism and Antiquities. This paper sets out the results of the first high‐resolution geospatial mapping and recording of rock art at this remote site. The research saw the innovative use of a differential GPS to record rock‐art panels to within 5 mm of accuracy at the site of Shuwaymis‐2, the first time that such technology has been used to record rock art in the Arabian Peninsula. With such technology it was possible to show which of eighty‐three late prehistoric rock‐art panels surveyed were in their original position and which had fallen, and to demonstrate that there was spatial homogeneity of rock‐art styles and composition across the site. The mapping recorded multiple panels of cattle, ibex, equid, large cat and other animals. The depictions of lions and cattle in particular indicate that the rock art must have been engraved no later than the early Holocene humid phase (c.10–6 ka BP).     

Revisiting the Parietal Art of Wonderwerk Cave,South Africa

Seen by all who visit Wonderwerk Cave, the rock paintings that adorn its walls have attracted less attention than many other aspects of the site. The paper gives a brief account of their history and significance and of factors that have constrained their study. Graffiti damage and restoration added layers through which researchers would need to delve in order to understand them archaeologically. Pointing to directions for future work, the paper concludes with discussion on a currently debated category of southern African rock art, the “non-entoptic” geometric rock art tradition, to which the Wonderwerk Cave rock paintings would belong. A shift in theoretical focus is advocated for comprehending local contingencies in the formation of rock art “traditions” rather than simply assuming the prior existence of such constructs.     

Designing Digital Recording for Volunteers in Rock Art Surveys,Management Plans and Public Outreach in the Cederberg,South Africa

The rock art survey and recording project described in this paper was designed for volunteers and heritage professionals involved in locating and mapping the position of rock art and other archaeological sites in the field, recording basic details for conservation and management, and making these details accessible in digital format for researchers who might want to undertake further investigation. An OpenDataKit (ODK) App with a digital site recording form was designed for mobile phones to be used in the field and to send data directly to the digital inventory of the South African Heritage Resources Information System (SAHRIS). The inventory has accumulated over 3000 sites with Later Stone Age rock paintings in the mountainous terrain of the Cederberg, a region that includes properties in the serial Cape Floral Region World Heritage Site in the Western Cape Province. More than a third of these rock art sites have been added to the database since 2007 by the members of the South African Archaeological Society. The information forms the basis for rock art management plans that are given to property owners to guide them in maintaining the value of the rock art. Interpretation of the information has raised awareness of the significance of the rock art in its historical and landscape setting with a trail and information boards. Local residents and CapeNature staff, who have received training in rock art monitoring and tourist guiding, play a key role in implementing the management plans for CapeNature properties, and monitoring individual sites and trails. The broader international context of volunteer programmes for archaeological site recording suggests that this type of programme has the potential to raise awareness of rock art beyond books and visits to museums and public lectures.     

Predicting Probabilistic-Based Strong Ground Motion Time Series for Citadel of Arg-E-Bam (South-East of Iran)

The main objective of this article is to present a probabilistic-based strong motion compatible with the source-path and site soil condition given the probability of exceedence for citadel of Arg-e-Bam site bed rock (South-East of Iran). A Fourier amplitude spectral attenuation relation for bed rock beneath the site is proposed which permits the estimation of time-histories through a probabilistic seismic hazard analysis procedure. Due to lack of data, the two well-known simulation techniques, point source and finite fault models have been used for generating hundreds of strong motion as input data. Tens of model parameter values such as stress-drop nucleation points were used, in each specified magnitude-distance, to reduce the uncertainty effects inherently existing in seismological/geological parameters. The proposed attenuation relation is validated by comparing the estimated strong motion, in the form of Fourier amplitude spectral, using the proposed attenuation relation with those of recorded ground motion data at three stations far away from the assumed source so that the results would not be influenced by the near source problems such as directivity and fling step. The results of proposed technique is assessed by comparing the estimated response spectra, with 10% probability of exceedence and 5% damping ratio, with those of traditional uniform hazard spectra. The proposed technique is supposed to be used in retrofitting procedure of international historical adobe structures in Arg-e-Bam site, which have been damaged during the destructive Bam earthquake 2003, Iran     

THESE ROCKS WERE MADE FOR WALKING: ROCK ART AT LEIRFALL,TRØNDELAG,NORWAY

One of the largest sites with Bronze Age type rock art in Norway is found at Leirfall in Stjørdal, Nord‐Trøndelag. The site, which consists of five panels, is dominated by footprints but at the same time a great variety of motifs is present. The footprints seem to lure visitors to walk from panel to panel, even across the panels, which are located at three different levels. The main focus is on the middle level, where the main panel (Leirfall III) contains more than 700 rock carvings. The walks between and around the panels are described; at the same time the Leirfall rock carvings are seen in a wider context. Most footprints are likely to represent children and it is argued that the site was used for the performance of public rites during initiations. However, symbols normally found only on decorated grave cists are present, too, particularly on the upper panel, which cannot be seen from below. Death rituals may also have been performed.

Ground-Motion Prediction Equations Based on Data from the Himalayan and Zagros Regions

This study derives ground-motion prediction equations for the horizontal elastic response spectral acceleration for 5% damping for application to the Indian Himalayas. The present equations include a consideration of site category (rock/soil) and style-of-faulting (strike-slip/reverse). Due to a lack of near-field data from India, additional strong-motion data have been included from the Zagros region of Iran, which has comparable seismotectonics to the Himalayas (continental compression). A set of 201 records from 16 earthquakes were used within the regression. The derived model predicts similar ground motions to previously published equations for the Himalayan region but with lower standard deviations.     

Saharan prehistoric basketry. Archaeological and archaeobotanical analysis of the early-middle Holocene assemblage from Takarkori (Acacus Mts., SW Libya)

The paper presents the large set of basketry and other worked fibre artefacts constituting the perishable artefacts assemblage from the Takarkori rock shelter. This site is located in southwestern Libya, central Sahara. Its well-preserved Holocene stratigraphy testifies to human occupations by foraging groups (Late Acacus culture; ca. 9000–7400 uncal years bp; ca. 8300–6100 BCE) and herders (Pastoral cultures; ca. 7400–4500 uncal years bp; ca. 6400–3000 BCE).     

Minateda rock shelters (Albacete) and post-palaeolithic art of the Mediterranean Basin in Spain: pigments,surfaces and patinas

The inorganic and organic fractions of two microsamples of prehistoric paint from the same site, the Minateda rock shelters, are analysed here for the first time. The two samples correspond to two rock shelters of different styles (Levantine and schematic) – Abrigo Grande de Minateda (The Great Rock Shelter of Minateda) and Abrigo del Barranco de la Mortaja (Del Barranco de la Mortaja Rock Shelter). Since its discovery, historiographical tradition has emphasised the Abrigo Grande de Minateda, with its magnificence and complexity, as emblematic of the origin and evolution of rock art in the Mediterranean Basin of the Iberian Peninsula (a UNESCO World Heritage Site). Four complementary techniques –Microphotography, Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDX), Raman Spectroscopy and Gas Chromatography–Mass Spectroscopy (GC–MS)– were combined to identify and characterise the physicochemical properties of the paint and of the surface. We present an interpretation of the results that leads us to define complex taphonomic alterations beyond the usual distinction of layers that include the surface, pigments and patinas.     

The environmental context of a prehistoric rock carving on the Bjäre Peninsula,Scania, southern Sweden

Palaeoecological analysis of peat deposits from a small bog at Lingården, southern Sweden, have been used to examine the nature and timing of vegetation changes and anthropogenic activity associated with a nearby rock carving located close to the edge of the wetland. This study is the first of its type to investigate the environmental context of rock carvings in southern Sweden. Debate has tended to focus on chronology and iconography, with little consideration of the environmental relationships of rock carvings and how vegetation may help construct a site within its surrounding landscape. The pollen evidence from Lingården demonstrates that the rock carving was located in an isolated semi-wooded setting during the late Bronze Age. This is in stark contrast to several other pollen studies from the Bjäre Peninsula that record widespread woodland clearance and agricultural activity from the late Neolithic–Bronze Age transition. The results of this study support hypotheses that suggest complex rock carvings, such as Lingården, were separated from settled areas. This sense of separation and isolation is reinforced by the vegetation surrounding the rock carving. This paper also discusses the relationship between charcoal in the pollen sequence and evidence that the decorated outcrop had been burnt.     

PREHISTORIC ROCK ART FROM PAINTED BLUFF AND THE LANDSCAPE OF NORTH ALABAMA ROCK ART

Abstract

Painted Bluff in northern Alabama is one of the richest and most elaborate open-air rock art localities in the Eastern Woodlands, rivaling some of the Southeast’s dark zone cave art sites discovered over the past several decades. Known for more than a century, the site has never seen detailed documentation until now. Painted Bluff contains motifs similar to iconography associated with Mississippian ceremonial objects, and a radiocarbon age determination (cal A.D. 1300–1440) would indicate contemporary use of the site. More than 80 images were painted on the cliffs, most using red mineral pigments but some reflecting polychromatic use of differently colored minerals. We present examples of the Painted Bluff artwork and discuss the site in the broader context of prehistoric rock art on the southern Cumberland Plateau and in northern Alabama.     

Rock art and social geography in the Upper Paleolithic. Contribution to the socio-cultural function of the Roc-aux-Sorciers rock-shelter (Angles-sur-l’Anglin,France) from the viewpoint of its sculpted frieze

This article is about the contribution of rock art to current studies on the social geography of European Paleolithic populations. The socio-cultural function of the Roc-aux-Sorciers decorated and occupied rock-shelter is considered through its monumental sculpted frieze. This approach is based on the intended audience, analyzed through the perception of this rock art and the archaeological context of the associated occupations. The site is also considered with regard to the other local decorated sites dated to the Middle Magdalenian with which it shares strong similarities (La Marche, Les Fadets, Réseau Guy Martin).     

A NARRATIVE TURN: HUMAN AGENCY IN ROCK CARVINGS AT NÄMFORSEN,NORTHERN SWEDEN

The idea to create pictorial narratives seems to have occurred long after humans learned to produce iconic images, that is, depictions based on visual similarity to external objects. In Scandinavia, e.g. in Gärde, Sweden or Stykket and Bøla, Norway, early Mesolithic images (e.g. rock carvings from before c.5000 BCE) often feature animals that are solitary or without suggestion of causal or narrative relations to other figures, although they sometimes are grouped by proximity or are superimposed on each other. Notable is also the almost complete absence of human figures. However, in subsequent Neolithic configurations (after c.5000 BCE), there are renderings of human agents involved in various forms of interaction with each other or with animals, often within distinguishable ‘scenes’ or compositions. In this paper we outline the emergence of pictorial narratives in Scandinavian rock carvings. In particular, we focus on some of the first depictions of human agency as displayed in Nämforsen, Sweden (c.5000–1800 BCE). Further, we present an analysis of occurring human-animal relationships, interpretable as early attempts to create narrativizing images.     

WEST OF THE BEST: ROCK ART AND ARCHAEOLOGICAL DISCOVERIES IN THE DORO !NAWAS REGION OF NORTHWEST NAMIBIA

The Northwest of Namibia bears a concentration of rock art that is among the highest in the world. One of the centres is Twyfelfontein, a cluster of sites surrounding a waterhole at the eastern fringe of the Namib Desert, classified as the prime rock engraving site in southern Africa and designated a UNESCO World Heritage Site. Recent prospections in the desert west of Twyfelfontein have resulted in the discovery of engravings and paintings that exceed those at the UNESCO site, both in quantity and quality. Our contribution to this volume in memory of Klavs Randsborg introduces this newly discovered archaeological landscape and discusses the connection between water ‐ a rare commodity in the desert environment ‐ and the rich array of rock art and other archaeological features found here.     

Identification of pigments used in rock art paintings in Gode Roriso-Ethiopia using Micro-Raman spectroscopy

In this paper we present results on the rock art painting materials from the Gode Roriso rock shelter, located in the eastern Hararghe region of Ethiopia. This analysis included X-microfluorescence, Micro-Raman spectroscopy and microstratigraphy. As far as the results of the analysis are concerned, a white natural wax (beeswax), carbon black and iron oxides (a mixture of haematite and magnetite) along with charcoal particles (forming as a red colourant) have been applied on a natural substrate constituted of granite containing feldspar crystalline forms. Although very much a science-based piece of research, the results have far-reaching outcomes for understanding the sequencing of pigment application.     

OPTICAL DATING OF SINGLE AND MULTIPLE GRAINS OF QUARTZ FROM JINMIUM ROCK SHELTER,NORTHERN AUSTRALIA: PART I,EXPERIMENTAL DESIGN AND STATISTICAL MODELS*

Jinmium rock shelter is famous for the claims made by Fullagar et al. (1996) for the early human colonization and ancient rock art of northern Australia. These claims were based on thermo-luminescence ages obtained for the artefact-bearing quartz sediments that form the floor deposit at the site. In this paper, we outline the background to the optical dating programme at Jinmium, and describe the experimental design and statistical methods used to obtain optical ages from single grains of quartz sand. The results, interpretations, and implications of this dating programme are reported in a companion paper (Roberts et al. 7999, this volume).     

Games on the seashore of Salalah: the discovery of mancala games in Dhofar,Sultanate of Oman

During the 2013 fieldwork of the French archaeological mission along the shores of the Arabian Sea, mancala games were discovered on the seashore of Salalah at the site of Ad‐Dahariz. They are cup‐hole carvings made directly into rock slabs and distributed in six distinct zones of the site. They usually consist of fourteen cup‐holes aligned in two lines of seven, two supplementary holes being sometimes present on each side. They are the first of their kind in South Arabia and can be compared to similar configurations of carved games elsewhere in Arabia, such as at Jebel al‐Jassasiya, Qatar. This paper presents the potential origins of this game in the region, as well as a plausible dating of their use.     

Effect of Horizontal Component Definition on the Characterization of Vertical Ground Motions: Application to Eastern Canada

In this article, ground motions recorded on rock sites in eastern Canada are studied in order to characterize their vertical acceleration components. Emphasis is placed on the sensitivity of vertical-to-horizontal spectral ratios to: (i) inter-component intensity correlations and (ii) the use of geometric mean horizontal components at each site instead of considering them individually. Four different definitions of horizontal components are investigated. Vertical-to-horizontal spectral ratios are compared with the findings of other researchers. We illustrate how the results can be used to evaluate vertical acceleration demands on rock sites in eastern Canada.     

Holocene Deposits of Saharan Rock Shelters: The Case of Takarkori and Other Sites from the Tadrart Acacus Mountains (Southwest Libya)

The excavation at Takarkori rock shelter is part of a long-term study of Holocene cultural dynamics in southwest Libya begun in the early 1990s. With a rich Holocene occupation, the area is one of the key spots for reconstruction of human occupation of the last 10,000 years. In this region, similar to the case in the rest of the Sahara, most of the data come from surface investigations at open-air sites, while excavated caves and rock shelters provide just a few. Although less exposed than open-air sites, Holocene archaeological deposits in Saharan caves and rock shelters are characterized by a fairly dynamic nature. Loose sediments, coupled with variability of human occupations and magnitude of natural agents, determine multiple alterations to the archaeological deposits in sheltered sites. In this paper, we present the nature and meaning of the archaeological deposits at Takarkori rock shelter, where a relatively large area has been recently excavated, showing a stratigraphic sequence extending from c. 9,000 to 4,200 BP, unevenly represented by several occupation pulses. In order to sharpen understanding of the development of human occupation at this site, specific procedures for the study and recording of the archaeological deposit have been developed, along with a program of extensive radiocarbon dating. Data from the Takarkori sequence ultimately will be integrated with available published stratigraphies from the Acacus Mountains, with the aim of reviewing the results from past excavations.
