Pigment analysis in Bronze Age Aegean and Eastern Mediterranean painted plaster by laser-induced breakdown spectroscopy (LIBS)

Laser-Induced Breakdown Spectroscopy (LIBS) was used in the examination of Bronze Age painted plaster samples from several sites in the Aegean and Eastern Mediterranean. The elemental content of paint materials was determined in most cases leading to the identification of the pigment used in agreement with data from analyses of the same samples with other established techniques. The analyses demonstrate that a virtually non-destructive technique such as LIBS provides sufficient data for the elemental characterisation of painting materials while in parallel has the capability for routine, rapid analysis of archaeological objects enabling the quick characterisation or screening of different types of artefacts. This certainly shows an important way forward in technological studies of fragile and scarce archaeological material.     

Isenya: état des recherches sur un nouveau site acheuléen d'Afrique orientale

Résumé Isenya est le premier site acheuléen fouillé sur les hauts plateaux du Kenya. Sa richesse en vestiges lithiques et fauniques en fait dès maintenant un gisement important pour la connaissance des hominidés du Pléistocène moyen. Isenya est inclus dans un contexte sédimentaire fluviatile, indiquant que les hommes préhistoriques se sont installés sur une barre sableuse, le long d'une rivière qui était alors peut-être pérenne. La convergence des informations géologiques et archéologiques permet d'expliquer la mise en place des vestiges, la positionin situ de plusieurs niveaux d'occupation superposés, le faible degré de perturbation qu'ils ont subi, et l'origine essentiellement anthropique des associations os/pierres. L'industrie lithique est caractérisée par une grande abondance de bifaces et de hachereaux dont les proportions varient dans le temps. Une première analyse de l'ensemble apporte d'ores et déjà des indications sur les comportements techniques: les chaînes opératoires sont décryptées, depuis l'acquisition des matériaux jusqu'à l'obtention des outils. La faune associée à cet outillage est dominée par des animaux de savane ouverte (Alcelaphini etAntilopini). Son étude détaillée mettra en évidence les stratégies d'acquisition du gibier et son mode de consommation. Attirés, entre autres raisons, par la proximité de l'eau et des affleurements de phonolite, source principale de matière première pour l'outillage, les hominidés ont occupé cet enfroit de façon répétée dans un court laps de temps, selon une périodicité à rapprocher sans doute des comportements de subsistance.

Isenya is the first Acheulian site excavated in the Eastern Highlands of Kenya. Very rich lithic and faunal remains in a fluviatile sedimentary context indicate hominid activity on a sandy bar next to a river, which was perhaps perennial. Microstratigraphy and archaeological data permit reconstruction of the processes by which the remains were deposited. Severalin situ occupation layers show only a slight degree of perturbation. The bone assemblage is of anthropic origin, and the lithic industry is characterized by an abundance of bifacial pieces, level VI being particularly rich in cleavers. From the analysis of the lithic industry we can obtain some idea of hominid technological behaviour, most notably the operational chains of tool production from the procurement of raw materials to the knapping sequences. The fauna associated with the lithic materials is dominated by animals of the open savanna (Alcelaphini andAntilopini); and its detailed study will allow us to specify the strategies used in the procurement of game and its subsequent consumption. Without doubt, the reasons for hominid occupation at this particular site will be impossible to explain fully. However, choice of this location, where evidence for several different activities has been uncovered, should be considered in terms of the proximity both of water and of outcrops of phonolite, the principal raw material for tool-making. Repeated occupation by hominids over a short time may, perhaps, correspond to the periodicity of their subsistence behaviour.
