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

The phenomenological tradition stands opposed to contemp orary cognitive science in this, that so far from being a mere thing in the physical world, a thing whose mind would contain some mental representation, the lived body is constituted in its sense of being for the subject by being used and actively appropriated by this self-same subject, as agent. Though not already generally acknowledged, there are important similarities between this conception and one, which emerges from the literature of brain cartography over the last twenty years, that of a functional morphogenetic neurodynamics, induced and modulated by experience in a relatively autonomous way, in relation both to the anatomic structures of the body, as well as the cytoarchitectonic frontiers of brain tissue. Taking advantage of the latter similarities, neuroscientific data can be employed to confirm the Husserlian theory of constitution against the attempts on the part of cognitive science to discredit it, and this whether we are talking about its later modification at the hands of Merleau-Ponty or the original version, which is that of a subjective (transcendental) auto-constitution of the lived body on the basis of the practico-kinoesthetic experience of «I move my body».  相似文献

A total of 51 ancient oak wood samples originating from various European archaeological sites, dating from the Neolithic period to the 18th century, were assayed for the presence of reproducible chloroplast (cp) DNA sequences. Five polymorphic chloroplast fragments were targeted. Only five of the samples could be fully genetically characterised, revealing four different oak cpDNA haplotypes. In all cases, the haplotypes detected on ancient woods and the haplotypes characterised from fresh samples from the same localities matched. Overall, this congruence is consistent with a genetic continuity between ancient and modern European oaks, confirming the hypothesis that the mapped genetic patterns largely reflect the original structure that established during the post-glacial. This stability of the genetic structure implies that, in the future, the technique could be used to infer or confirm the transport of wood by man, providing interesting perspectives for the genetic analysis of ancient woods.  相似文献
