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.  相似文献

Four blue-glazed faience jars, on exhibition in the Louvre Museum, are referred to as the canopic jars of Rameses II. Their recent typological re-examination rendered this original assignment questionable. In order to clearly determine their use, a study of two successive organic residues from the canopic jars, using molecular biomarkers analysed by GC-MS and LC-MS and absolute dating by 14C, was initiated. The results revealed that these two materials were not contemporary to the reign of Rameses II. The first one, scraped from the interior face of one jar, was identified as an unguent made of coniferous oil and animal fat and dated from the Third Intermediate Period. The second one, originally stored with glued linen inside one jar, is likely an embalming substance, made of pure vegetable resin (Pistacia) and dated from the Ptolemaic Period. These results clarify a controversy which has been lasting over a century. The famous blue-glazed faience jars are not the canopic jars of Rameses II but are confirmed as situlae which were reused at least two times: first to store unguents during the Intermediate Period and later to store embalming packages of an unknown person during the Ptolemaic period.  相似文献

This article presents and discusses the chronological layout of the final Mousterian and Uluzzian levels of Fumane Cave in northern Italy using 14C, ESR and TL methods. Given its complex sedimentary and cultural succession, Fumane is a key site to assess the Middle–Upper Palaeolithic transition in Southern Europe and to explore Neanderthal behaviour and to compare it with the first Aurignacians. Large ranges defined by the ESR and TL dates cover the radiocarbon ages for units from A11 to A4, respectively, from 42.8 to 32.5 ka BP become progressively younger in agreement with the stratigraphy, despite high dispersions within the same unit. Our estimates using chronometric data seem to support the hypothesis that the sequence may cover almost 10,000 radiocarbon yr and that from comparison with the sedimentological and palaeoecological data, the late Middle Palaeolithic and the early Upper Palaeolithic at Fumane occur in sediments formed under moderately cool to mild climatic conditions correlated to the Hengelo-Interstadial, shifting towards cooler and drier conditions. Finally, comparisons between the Fumane data set and other sites in the North-Adriatic region are discussed.  相似文献

The metallurgical analysis of a copper bead from a Neolithic burial (6th millennium ) at Mehrgarh, Pakistan, allowed the recovery of several threads, preserved by mineralization. They were characterized according to new procedure, combining the use of a reflected-light microscope and a scanning electron microscope, and identified as cotton (Gossypium sp.). The Mehrgarh fibres constitute the earliest known example of cotton in the Old World and put the date of the first use of this textile plant back by more than a millennium. Even though it is not possible to ascertain that the fibres came from an already domesticated species, the evidence suggests an early origin, possibly in the Kachi Plain, of one of the Old World cottons.Résumé: L'analyse métallurgique d'une perle en cuivre, provenant d'une tombe néolithique (VIe millénaire av. notre ère) de Mehrgarh, Pakistan, a permis la découverte de plusieurs fibres textiles, conservées par minéralisation. Elles ont été caractérisées par une nouvelle méthode, combinant l'utilisation d'un microscope à lumière réfléchie à celle d'un microscope électronique à balayage, et ont été identifiées comme étant du coton (Gossypium sp.). Les fibres de Mehrgarh constituent la plus ancienne attestation du coton dans l'Ancien monde et son utilisation a pu être reculée de plus d'un millénaire. Bien qu'il ne soit pas possible d'attribuer avec certitude les fibres à une espèce déjà domestiquée, ces nouvelles données suggèrent une origine ancienne, éventuellement dans la Plaine de Kachi, d'une des espèces cotonnières de l'Ancien monde.  相似文献
