Acoustics and Levantine rock art: auditory perceptions in La Valltorta Gorge (Spain)

This article explores the relevance of acoustics as a factor for in the production and active use of Levantine rock art in Spain. The renowned rock art area of La Valltorta Gorge serves as a case study. Two experiments are described; the first assessed whether the sites with the most painted motifs had better acoustics than those with fewer motifs. The second tested which areas in La Valltorta Gorge had better acoustics and whether there was a difference between the acoustics of the decorated area and the contiguous sectors of the Gorge where no paintings have been found. In both experiments different sounds and pitches were used. The results suggest a strong relationship between the painted areas and the sonority of the place, with the major sites generally having provided the best results, with the exception of the sonority when facing the rock art panels. It is suggested that La Valltorta Gorge was chosen to be decorated with a view to increasing the perceptual impact of the rituals that may have been held at rock art sites due to the amplification caused by the echoing and resonance.     

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.     

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).

The rock art of the Côa valley,Portugal: Significance,conservation and management

Abstract

The Côa river valley is the largest open-air Palaeolithic art site currently known. Some 150 decorated panels have already been found, spread along 17km. The whole complex would have been submerged under 100m of water if construction of the large Foz Côa dam, begun in 1992, had been allowed to continue. The dam project was halted in 1995 and a 200km² archaeological park is being established in this area, which is now legally protected at the highest level as a National Monument. Public access to selected sites is organized through four-wheel drive. tours of groups of eight people accompanied by guides appropriately trained in archaeology and rock art studies. Visitor Centres have been set up in restored traditional houses located in the villages around the periphery of the park. A Museum of Rock Art and Archaeology and associated research facilities is to be established at the site of the now abandoned dam.     

Books of Life: Biography and Memory in a Bronze Age Barrow

An important round barrow with a primary Beaker interment and numerous secondary burials was excavated at Barnack, Cambridgeshire, in 1974–6. Reading the published report gives the impression that many of the secondary interments, by their location and attitude, reveal a memory of the primary rite. It is argued that the sequence of burials at Barnack reflects the genealogical history of the group which used the site. A series of events emerges, structured primarily by the concept of 'difference', which both retain the unique identities of the buried individuals and form a constructed narrative of society. Similar sequences are evident at other Bronze Age barrows in the east Midlands and elsewhere. Such sites seem to represent our closest approach to the 'embodied experiences' of prehistoric actors.     

Molluscan evidence for diet and environment at Saar in the early second millennium BC

Molluscan shells were abundant throughout the archaeological deposit at Saar. Analysis of species composition and abundance provided evidence for marine food in the diet and for local marine environments. The most important edible species were bivalves such as pearl oyster and clams with smaller numbers of gastropods, for example conch and muricid snails. The range of archaeological species indicated that there were no major changes in the intertidal marine habitats. They have not provided further evidence for the location of the prehistoric coastline which might have differed from the present day. Flotation samples contained small freshwater gastropods which have not been recorded previously from sites in the Arabian Gulf. These gave evidence for the use of water in the site and for nearby freshwater springs.     

Context for a carnyx: excavation of a long-lived ritual site at Leitchestown,Deskford, Moray,north-east Scotland

Excavations at the findspot of the Deskford carnyx, a major piece of Iron Age decorated metalwork found in a bog in the early nineteenth century, revealed a special location with a long history. Early Neolithic activity on the adjacent ridge consisted of massive postholes and pits, suggesting a ceremonial site. An Early Bronze Age cremation became the focus for a feasting event in the Middle Bronze Age. Around this time, peat began to form in the valley, with vessels of pot and wood smashed and deposited there; these activities on ridge and bog may be connected. Activity in the bog intensified in the later Iron Age, when offerings included quartz pebbles, the dismantled carnyx head, and two unusual animal bone deposits. The ridge was cut off at this period by a complex enclosure system. This Iron Age activity is interpreted as communal rituals at a time of increasing social tension. The site’s significance in this period may stem from its unusual landscape character, with flowing water to one side and a bog to the other. The area saw occasional activity in the Early Medieval period, but its significance had waned.     

FINITE FAULT MODELLING OF NEAR-FIELD ROCK MOTIONS IN THE NEW MADRID SEISMIC ZONE

Due to lack of strong motion records, point-source and finite-fault models have been used to simulate far-field motions at Memphis and St. Louis Cities from earthquake events in the New Madrid Seismic Zone. However, near-field rock motions and their associated uncertainties have never been studied within this zone. The objectives of this study are to develop a simple procedure to account for the uncertainty effect of earthquake source parameters, to analyze the sensitivity of near-field rock motions to input source parameters, and finally, to generate rock motions at two sites located within 11 km from the southwestern segment (strike-fault) and a third site bove the Reelfoot Rift (reverse fault) using a well-validated finite-fault simulation program; FINSIM. An equal-weight logic tree was developed to ensure that the assumed uncertainties are within physical, geological, and seismological constraints. For each site, 100 acceleration time histories with various combinations of parameter uncertainties were respectively simulated for an earthquake of M _w 7.0, 7.5, and 8.0 from each of the two faults. Their average spectral accelerations were in good agreement with those derived from the attenuation relation-ships representative to the Central and Eastern United States. Numerical simulations indicated that spectral accelerations are sensitive to the slip velocity, depth to top of fault, fault strike, slip distribution, and hypocentre location along the strike.     

Makaynûn and its territory: the formation of an urban centre during the South Arabian period in the Hadramawt

Work at the site of Makaynûn in eastern Hadramawt (Yemen) and surrounding territory has yielded information on ancient settlement patterns in southern Arabia. This small regional centre lay within an area marked out by a network of seasonal flood‐water cultivation systems that irrigated agricultural areas. Each system was associated with one or more villages that were contemporary with the central site. As well as providing a communal refuge, the central site contained religious buildings, dwellings and doubtless the residence of the local elite, within the shelter of a defensive enclosure. This territory was overlain by a symbolic geography defined by the location of the sanctuaries and cemeteries of the Makaynûn community. This model of settlement was repeated all along the valley, where comparable systems were found at the mouths of the main tributary valleys.     

Public archaeology and political dynamics in Portugal

Abstract

The two hardest-fought rock art conservation battles in the history of the International Federation of Rock Art Organizations have been the campaigns to save the petroglyph sites in the lower Côa valley of northeastern Portugal and in the Guadiana valley in southeastern Portugal. They have become test cases of rock art conservation and site management issues. This paper summarizes the history of these campaigns and the effects they had on rock art management practices in Portugal. Specific attention is given to the responses of the public archaeologists in this controversy, and to some specific and generic aspects of the issue that are in a general sense relevant to the sociology of state-funded agencies charged with the protection of archaeological resources.     

U-Pb dating of zircon: A sourcing method for pottery from La Morena archaeological site,north-west Colombia*

U-Pb zircon radiometric dating and petrographic thin-section analysis were used for provenance identification of Ferrería and Marrón Inciso pottery styles from La Morena archaeological site in northwestern Colombia. U-Pb dating was applied to zircons recovered from pottery and rock samples from nearby geological units. The results suggest at least three distinct sources: the metamorphic rock unit on which the archaeological site is located, a granodiorite unit that outcrops further away from the site, and a mafic rock that cannot be attributed with certainty. U-Pb in zircons proved to be effective as a provenance method, where ages of the possible source rocks are well constrained, and can be applied to areas where traditional sourcing methods may be problematic.     

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.     

Solifluction-induced modifications of archaeological levels: simulation based on experimental data from a modern periglacial slope and application to French Palaeolithic sites

The taphonomic study of Petit-Bost, Croix-de-Canard and Cantalouette II, three Palaeolithic sites that were recently discovered near Périgueux and Bergerac (Dordogne, France) in a colluvial context, has enlightened the difficulty of adequately appreciating the relative role of cultural and natural processes in site spatial patterning. Periglacial solifluction was thought to have played a significant role in site formation. Because the nature of the modifications induced by solifluction was still poorly understood, a simulation was made using data of soil movement recorded at La Mortice (French Southern Alps, 3100 m in elevation) in a modern periglacial environment. The results show that, for a knapping location, the first steps of deformation are typified both by a downslope translation of the location center and by an anisotropic diffusion of the artifacts. The knapping spot becomes elongated along the slope, with a dense relic concentration of artifacts in the upslope portion. This type of pattern has been obtained after 100–200 years of simulated displacement according to the climatic and soil conditions that characterise the La Mortice site. The ultimate stages of deformation show that the artifact distribution tends to homogenise on larger surfaces and resemble a random distribution. The ability of the simulated patterns to closely fit those observed in archaeological contexts is evaluated at three sites from Southwestern France. At Petit-Bost, the hypothesis of limited solifluction explains accurately the association of both cultural (artifact concentrations) and natural (artifact preferred orientation) features. At Croix-de-Canard, long-term solifluction can be proposed. By contrast, the simulated patterns do not describe the structures observed on the steeper slopes at Cantalouette II, where the knapping spot transforms into distinct solifluction lobes.     

Art in time. Diachronic rates of change in the decoration of bone artefacts from the Beagle Channel region (Tierra del Fuego, Southern South America)

This paper explores the differential rates of diachronic change developed by diverse features of portable art in southern Tierra del Fuego. It is argued that decorative designs and techniques, which simultaneously constitute each decorated artefact, had asynchronic rates of change throughout the archaeological sequence. Results indicate that: (I) decorated harpoon points (1) had a broader and more complex design repertoire which entailed a higher labour investment and showed a faster rate of change than beads, due to a greater individual input in their decoration, (2) were richly decorated in spite of their high risk of loss/fracture, yet their decoration was concentrated in the early period of the archaeological sequence and then decreased in time due: a) to such loss/fracture risk, which jeopardised the labour invested in their decoration, (b) to a relative decrease in pinniped hunting which might have reduced the socio-economic and symbolic value of harpoons; (II) decorated beads (1) had a simpler and more standardised design repetoire which entailed a lower labour investment and showed a slower rate of change than harpoons, due to a stricter process of teaching/learning or imitation during their production and a collective way of ornamentation during their display, (2) increased with time and have been decorated during the three periods of the archaeological sequence due to: (a) their lower risk of loss/fracture, which did not endanger the labour invested in their decoration, (b) their social function as a shared form of ornamentation; (III) decorative techniques had a slower rate of change than decorative designs throughout the archaeological sequence due to their differential instrinsic variability potentials.     

ROCK ART SITES IN JAMAICA AND THEIR ETHNOGRAPHIC INTERPRETATION

26 sites with Pre‐Columbian (Taíno) rock art are known in Jamaica, most with petroglyphs only, but there are four with painted images, and three of these are discussed: Mountain River Cave, Potoo Hole, and Spot Valley Cave. In addition, an account is given of the Warminster rock shelter, which has petroglyphs described as among the best remaining in Jamaica. Spot Valley Cave was newly surveyed in 2005, with the help of the Jamaican Caves Organization, and in the same year a rescue operation to restore the Warminster petroglyphs was carried out, in cooperation with Dr Johannes Loubser. Comparisons are made, where appropriate, to Taíno artefacts in different materials, and also to Pre‐Columbian images on other islands in the Caribbean, notably Puerto Rico. The interpretation of the Taíno images, in Jamaica and elsewhere, relies to a considerable extent on the “Account of the Antiquities of the Indians”, compiled by Fray Ramón Pané in 1494–1498, on the express instructions of Columbus. Whatever the shortcomings of a narrative compiled by an outsider, we would be much worse off without it.     

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.     

Recent Excavation and Recording at the New Neolithic Rock Art Site of Vallée Aux Noirs,Buthiers (Seine‐et‐Marne,France)

Following the exceptional discovery of Neolithic engravings on a boulder at Vallée aux Noirs in the Fontainebleau forest, south of Paris, an excavation trench was opened in order to access the buried part of the decorated rock panel and explore the stratigraphic context of the artwork. A palaeosol was found two metres below the modern ground level, underneath multiple layers of sterile sandy soil forming a very compact sequence from which only one archaeological artefact was recovered – an Iron Age fibula (c.200–300 BC). Dating of the palaeosol was attempted through two different methods: AMS dates from charcoal suggest a significant span from the Early Bronze Age to the Iron Age, while two more consistent OSL dates point to formation of the palaeosol during the Late Neolithic (3500–3000 cal BC). The entire engraved rock surface (16 m²), including its buried part, was fully recorded. Four main semiotic groups were identified: a typical fifth‐millennium crook‐hafted axe with a ring, two boats with steering oars, and a central, very tall human figure dominating the composition from its 3.5‐metre height.     

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.
