Pigments from the Middle Palaeolithic levels of Es-Skhul (Mount Carmel,Israel)

Discovery of pigments at Middle Palaeolithic sites is of interest in the context of the ongoing debate about the tempo and mode of the emergence of modern human behaviour. Here we analyse four previously undescribed fragments of pigmental material from Es-Skhul shelter, layer B, Israel, McCown excavations, identified at the Department of Palaeontology, Natural History Museum, London. One of them is still partially embedded in the hard breccia characteristic of this layer. Inspection of breccia fragments from layer B has led to the identification of small pieces of red and orange pigmental material still enclosed in large clasts, further corroborating the attribution of the larger pieces analysed in this study to layer B. The four objects are studied using optical microscopy, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray (EDX), X-ray micro-diffraction (μ-XRD), Particle-Induced X-Ray Emission Spectrometry (PIXE), and Proton-Induced Gamma-ray Emission (PIGE). The specimens display various hues of yellow, orange, red, and one of them presents a gradual variation of shade from yellow to dark orange. SEM/EDX analysis identifies two specimens (Skhul 1 and 2) as being composed of iron-rich calcium phosphate, the third (Skhul 3) of potassium-rich clay with titanium-rich iron oxide inclusions, and the fourth (Skhul 4) of pure iron oxide crystals. TEM/EDX and μ-XRD analysis demonstrate that three pieces (Skhul 1, 2 and 4) were heated to at least 300 °C, a process that has partially or completely dehydrated goethite into haematite and changed their pristine yellow colour into orange or red. Skhul 3 shows no sign of heating, suggesting that its haematite content has a geological origin. The different mineral composition of the pieces suggests that they must come from a variety of sources. This implies that the associated collection strategies included the selection of materials that differed not only with respect to colour but also with respect to other physical and chemical properties. Although no formal proof exists that these lumps of pigmental material were deliberately heated, results obtained are consistent with this explanation.     

Stable isotope analysis of Late Upper Palaeolithic human and faunal remains from Grotta del Romito (Cosenza), Italy

Stable isotope analysis of carbon (δ¹³C), nitrogen (δ¹⁵N) and sulphur (δ³⁴S) were carried out on one of the largest assemblages of Late Upper Palaeolithic human remains in Southern Europe, at Grotta del Romito (Cosenza), Italy. The burials were stratigraphically dated from ca. 18,000 to 13,000 cal BP, which was confirmed by a series of new AMS dates made directly on the bone collagen. Dietary reconstruction from carbon and nitrogen stable isotopes revealed that eight of the nine individuals analysed, dating to the Final Epigravettian, had very consistent diets, rich in terrestrial animal protein, regardless of their age or sex. These included two individuals who were suffering from severe pathologies. A single individual, dating to the Evolved Epigravettian had a more variable diet, which was significantly enriched in protein from marine or freshwater fish compared to the later burials. Overall, the results are consistent with the very limited number of other studies which describe a change to more specialised and less variable subsistence strategies, in this case the hunting of large herbivores, towards the end of the Palaeolithic period. Sulphur isotope values of all of the nine burials and several faunal samples were notably consistent, showing no evidence of long-distance migration to the site from a different geological zone.     

Investigating links between ecology and bifacial tool types in Western Europe during the Last Glacial Maximum

We apply Eco-Cultural Niche Modeling (ECNM), using the Genetic Algorithm for Rule-Set Prediction, to reconstruct the ecological niches exploited by Middle Solutrean and Upper Solutrean populations during the latter stages of Heinrich Event 2 and the early part of the Last Glacial Maximum, respectively. We focus on the Upper Solutrean technocomplex and its regionally distinct styles of hunting weaponry to investigate whether regional cultural variability reflects a link between material culture and ecology. Our analytical approach uses archaeological and geographic data in conjunction with high-resolution paleoclimatic simulations and vegetation reconstructions for the two climatic phases in question. Our results indicate that cultural choices behind the production of specific projectile point types have at some level an ecological basis and are linked to particular environments. We also find that the identified pattern of Upper Solutrean territoriality has an ecological foundation, but that its stylistic expression in the variation of diagnostic armature types is likely a byproduct of cultural drift. We argue that ECNM is an effective means with which to evaluate the paleoecological pertinence of archaeologically defined artifact types and to identify the ecological and cultural mechanisms underlying material culture variability.     

The face of the poet Dante Alighieri reconstructed by virtual modelling and forensic anthropology techniques

This paper describes the multi-disciplinary approach to reconstruct the face of Dante Alighieri (1265–1321). Since Dante's sepulchre will be opened in 2021, the reconstructive process is based on morphological and metric data collected on the poet's cranium during the formal identification of his remains in 1921 by the anthropologist Fabio Frassetto, as well as on the resulting plaster model. Starting from this plaster model and a morphologically compatible reference mandible, since the original mandible was never found, a 3D digital model of the complete skull was obtained by reverse engineering and virtual modelling techniques. The most important aspect in this work was the method of virtual modelling proposed for the ex novo generation of the mandible. The physical model of the skull (cranium + mandible) was then produced by means of a rapid prototyping system. This model was finally used to recreate Dante's face via traditional facial reconstruction techniques currently used in forensic anthropology.     

Middle Stone Age bone tools from the Howiesons Poort layers,Sibudu Cave,South Africa

Recently discovered bone implements from Middle Stone Age (MSA) deposits at Sibudu Cave, South Africa, confirm the existence of a bone tool industry for the Howiesons Poort (HP) technocomplex. Previously, an isolated bone point from Klasies River provided inconclusive evidence. This paper describes three bone tools: two points and the end of a polished spatula-shaped piece, from unequivocal HP layers at Sibudu Cave (with ages greater than ∼61 ka). Comparative microscopic and morphometric analysis of the Sibudu specimens together with bone tools from southern African Middle and Later Stone Age (LSA) deposits, an Iron Age occupation, nineteenth century Bushman hunter-gatherer toolkits, and bone tools used experimentally in a variety of tasks, reveals that the Sibudu polished piece has use-wear reminiscent of that on bones experimentally used to work animal hides. A slender point is consistent with a pin or needle-like implement, while a larger point, reminiscent of the single specimen from Peers Cave, parallels large un-poisoned bone arrow points from LSA, Iron Age and historical Bushman sites. Additional support for the Sibudu point having served as an arrow tip comes from backed lithics in the HP compatible with this use, and the recovery of older, larger bone and lithic points from Blombos Cave, interpreted as spear heads. If the bone point from the HP layers at Sibudu Cave is substantiated by future discoveries, this will push back the origin of bow and bone arrow technology by at least 20,000 years, and corroborate arguments in favour of the hypothesis that crucial technological innovations took place during the MSA in Africa.     

Space Invaders in Barcelona: Political Society and Institutional Invention Beyond Representation

In the contemporary neoliberal urban dynamics, those agencies that are on the margin of society constantly disrupt the boundaries of civil representation and forge new institutional relations within the dynamics of urban governance. I explore how this process was enacted at the turn of the century in Barcelona, looking at two coeval social mobilisations: the lock‐in of undocumented migrants in the Iglesia del Pi (2001), and the project of las agencias at the Museum of Contemporary Arts (1999–2003), both of which unfolded in the central neighbourhood of Raval. The invasion of the boundaries of civil society emerges here as a double phenomenon—one that develops both within society and in relation to institutions, instituting new modes of urban politics.     

Fabio Luca Cavazza,the New Frontier and the opening to the left in Italy

This article focuses on the key role played by Fabio Luca Cavazza, founder of the publishing house Il Mulino, in the development of cultural relations between the US and Italy in the early Cold War by drawing on Cavazza’s personal papers, an as yet unexplored archival source. The Department of State and the Eisenhower administration opposed a government that included the Socialists. However, thanks to the special relationship he had with the ‘New Frontier’s men’, in particular Arthur Schlesinger Jr., Cavazza was able to revive the issue, showing how it was in line with Kennedy’s New Frontier policy.     

Average and core silver content of ancient-debased coins via neutron diffraction and specific gravity

The measurement of the fineness of debased ancient silver coins has proven to be a very difficult issue, which has been studied for a long time. In this paper, this subject is analysed, and the various consequences of the silver surface enrichment (SSE) are discussed exploiting the most recent investigations. A new model is proposed for the complex object that is an ancient-debased silver coin, based on the silver profiles measured on some sectioned specimens. The model is applied to a sample of 43 coins, mainly Roman victoriati, Cisalpine and Illyrian drachms (from late III to I century B.C.). The coins are investigated in two different ways: neutron diffraction (ND) and specific gravity (SG). The results of the two measurements are combined via the proposed model to provide a more complete numismatic information of the original fineness of the monetary alloy. As a result, a relation between SSE thickness and SG is derived, which, for these coinages, allows to estimate the original alloy silver content from a simple SG measurement; the same method can be used to study other debased coinages, provided that all the procedure (ND and SG) is applied.     

Sequential Incisions on a Cave Bear Bone from the Middle Paleolithic of Pešturina Cave,Serbia

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior.     

From exchange to voice. Voting in southern Italy

The article focuses on the Italian general election held on 4 March 2018, which was notable for the surprising results in southern Italy. These results will be analysed by looking at two dimensions of electoral behaviour: on one hand, participation and volatility, on the other the success of the protest parties, the Five Star Movement (M.5.S.) and the League. These features will be considered in relation to the territorial distribution of the vote. More specifically, in the 2018 election participation was exceptionally high, especially in the south which in some regions saw electors returning to the polls. But electoral volatility is still high. Both factors affected the extraordinary success of new protest parties and collapse of the traditional parties. Traditionally in the south the vote has gone to moderate and pro-government parties, but this time in all constituencies the M.5.S., an ‘eccentric’, protest or populist party-movement, which in many cases took over 40 per cent of the votes, with a peak of 50 per cent in Campania and Sicily. Further, the wave of protest votes favoured another party with no previous support in this geographical area, the League. It may be too soon to say whether these changes in the form and dynamics of the party system are long-lasting and able to achieve a lasting change in the political spectrum, but so far the outcome of election has given a further push to the radicalization of both electoral demand and supply.
