A laboratory cave for the study of wall degradation in rock art caves: an implementation in the Vézère area

The aim of this proposal is to present an original approach to the study and preservation of rock art caves. A multidisciplinary study of cave wall alteration will be performed to understand the impact of environmental context on the evolution of wall surfaces. The approach involves the choice of a cave with characteristics similar to painted caves in the studied area (Vézère Valley in Dordogne, France): e.g., cave wall alteration, lithology, morphology, etc. This selected cave is intended to become a laboratory cave, monitored for the acquisition of chemical, physical and biological environmental data on bedrock, air and fluids along with their characteristics. A cave without art or archaeological interest has been chosen specifically to conduct experiments, to make in situ analysis and to obtain samples. The results are to be completed by specific observations in several other caves and compiled in a database.     

Applying dynamics and comparing life tables for Pleistocene Equidae in anthropic (Bau de l'Aubesier,Combe-Grenal) and carnivore (Fouvent) contexts with modern feral horse populations (Akagera,Pryor Mountain)

In this study, we propose a method based on life tables currently used in population dynamics and ecology to compare the mortality curves of Equidae from anthropic and carnivore fossil assemblages with those from modern populations. The combined analysis of frequency (f_x) with various ecological parameters such as mortality rate (q_x), survival rate (l_x), fecundity rate (m_x), and killing factor (k_x), established for each age class, allows us to characterize the stability of fossil populations. These ecological parameters, developed in demography, correspond to many curves and constitute a complementary approach to interpret the two main mortality models, attritional and catastrophic, often evoked in zooarchaeology. The age structures of fossil horses from the anthropic sites of Bau de l'Aubesier (Vaucluse, France) and Combe-Grenal (Dordogne, France) and the hyena den of Fouvent (Haute-Saône, France) are compared to typical catastrophic modern populations of Equidae from the National Park of Akagera (Rwanda). We also used data collected by the Bureau of Land Management for present day feral horses from Pryor Mountain (Montana, USA) which constitutes a reliable referential of a stable living population. The characterization of age structures in those different contexts is discussed as well as the impact of Neanderthals and hyenas on fossil assemblages.     

Qu’est-Ce Quela «Littérature Générale»? La Culture Lettrée au Prisme du Marché du Livre de la Première Moitié du XX e Siècle

The aim of this paper is to shed light on the importance, for cultural history, of a professional concept from the publishing worl, for example « general literature » - a concept which goes against most of the usual forms of classification and division of intellectual output. Through the use of an « indigenous » source from within the publishing domain such as the advertisement notices published in Bibliographie de la France, one can show the coherence of a wide domain which encompasses - but also widely surpasses - the boundaries of literature as commonly conceived. As one category of publishing output, general literature can be characterized during the first half of the XX ^th century by the use of the same material form the 12mo whose profound significance is the intention to reach a « wide educated audience ». Thus, it is by taking into account the structure of this output that, through such a domain as general literature, the publishing market allows the question of the actual existence and aspects of learned culture to be raised.

Rebelles with a Cause: Women in the Haitian War of Independence, 1802–04

This article studies the role of white, black and mulatto women during the last two years of the Haitian War of Independence, also known as the Haitian Revolution (1802–04). It might be expected that women's contribution was limited in wartime, but this article concludes otherwise. Desirable women were sought as prizes symbolic of a man's status in colonial society, or actively used their appeal to obtain political favours. Women of colour contributed to the rebellion in the fields of logistics, espionage and even combat. They also experienced martyrdom when convicted of aiding the rebel army. White women, in turn, were considered such an integral part of the colonial order that the rebels, led by Toussaint Louverture and Jean‐Jacques Dessalines, targeted them, as well as other civilians, during the fighting, then proceeded to exterminate all surviving whites after the rebel victory.     

Strontium isotopic characterization of the Palmottu hydrosystem (Finland): water–rock interaction and geochemistry of groundwaters

The Palmottu hydrosystem is located in a granitic host rock in southern Finland. Along well‐defined pathways in the fractured crystalline rock, strontium isotopes are used to trace the degree of water–rock interaction (WRI) and mixing processes in groundwaters. The ⁸⁷Sr/⁸⁶Sr ratios range between 0.716910 and 0.735606 in the surface waters and between 0.719991 and 0.750787 in the groundwaters, but are between 0.720 and 0.735 in most of the samples. Moreover, the results show a lack of correlation between the water chemistries determining the classification into different water‐types (Na–Cl, Na–SO₄, etc.) and the results of the strontium (Sr) contents and Sr isotopic ratios. From a WRI standpoint, this implies that the Sr behaviour is independent of the water chemistry; the occurrence of large ⁸⁷Sr/⁸⁶Sr variations is site specific and mainly dependent on the lithology. A model to determine the ⁸⁷Sr/⁸⁶Sr ratio of water after interaction with granite was developed. This model is based on the assumption that Sr was derived from three minerals: plagioclase, K‐feldspar and biotite. The results of the calculation indicate that around half of the water analysed within the Palmottu hydrosystem can be explained by the weathering of the granites. However, clearly lower ⁸⁷Sr/⁸⁶Sr are observed in waters when compared to the calculated ⁸⁷Sr/⁸⁶Sr and other sources of Sr, with low ⁸⁷Sr/⁸⁶Sr, rather than the calculated granite–water interaction, which may be suspected. When comparing the ⁸⁷Sr/⁸⁶Sr and ion ratios (Ca/Na, Mg/Na, Sr/Na, Cl/Na), the scattering of the data can be explained by the presence of four end‐members: a brine component (low ⁸⁷Sr/⁸⁶Sr and Ca/Na ratios…), a deep granitic component (high ⁸⁷Sr/⁸⁶Sr ratios and low Ca/Na ratios…), a subsurface component (intermediate ⁸⁷Sr/⁸⁶Sr ratios associated with high Ca/Na ratios…) and a surface end‐member:snow and river drainage (low ⁸⁷Sr/⁸⁶Sr and low Ca/Na ratios…). These extreme end‐members define a series of WRI‐mixing line within a rather complex hydrosystem.     

The use of SEM-EDS,PIXE and EDXRF for obsidian provenance studies in the Near East: a case study from Neolithic Çatalhöyük (central Anatolia)

In this paper we evaluate the relative analytical capabilities of SEM-EDS, PIXE and EDXRF for characterizing archaeologically significant Anatolian obsidians on the basis of their elemental compositions. The study involves 54 geological samples from various sources, together with an archaeological case study involving 100 artifacts from Neolithic Çatalhöyük (central Anatolia). With each technique the artifacts formed two compositional groups that correlated with the East Göllü Da? and Nenezi Da? sources. The non-destructive capabilities of these methods are emphasized (albeit with certain analytical limitations in the case of SEM-EDS), suggesting important new techniques for Near Eastern obsidian provenance studies.
