La céramique Rhin-Suisse-France orientale de Passy "Richebourg Ouest" : un ensemble du Bronze final IIB dans l'Yonne

National audienceA 1994 archaeological evaluation at Passy «Richebourg» (Yonne) brought to light a pit containing material dating to the second period of the Late Bronze Age. The typochronological analysis of this material has dated it to the Bronze final IIb (well-known period in the East of France). This work is part of a number of short papers allowing us to work on the precise dating of this second period of the Late Bronze Age in the Yonne area.Un diagnostic réalisé en 1994 sur la commune de Passy (Yonne), au lieu-dit «Richebourg Ouest», a révélé une fosse très riche en mobilier attribuable à l'étape moyenne du Bronze final. L'analyse typo-chronologique de ce mobilier permet de l'attribuer au Bronze final IIb (période bien attestée dans l'est de la France). Cet article est la suite d'une série de petites monographies qui nous permettront de travailler sur la périodisation fine de cette étape moyenne du Bronze final dans le département de l'Yonne

Constantes et variations autour d’un modèle

Depuis les années 2000 avec l’essor de l’archéologie préventive, on constate, en Bretagne, un renouvellement important des données céramiques notamment avec la mise au jour de contextes domestiques du Bronze ancien. Ces découvertes permettent, aujourd’hui, de disposer de contextes clos et bien datés, propices à la mise en place d’une approche technologique. Cette approche permet d’intégrer les nouveaux corpus domestiques à la réflexion générale d’un point de vue typochronologique, mais également au plan des dynamiques culturelles et des réseaux d’échanges entretenus à l’échelle de la façade atlantique, tout particulièrement au travers des phénomènes d’emprunts, de copies et d’imitations.Since the 2000s with the rise of rescue archaeology, there is, in Brittany, a significant renewal of ceramic data especially with the discovery of domestic contexts of the early Bronze Age. These discoveries make it possible today to have enclosed and well-dated settings, conducive to the implementation of a technological approach. This approach makes it possible to integrate new domestic data to the overall reflection from a typochronological point of view, but also with regard to cultural dynamics and interaction networks maintained at the scale of the Atlantic seafront, especially through borrowing, copying and imitation phenomena.Desde los años 2000, y gracias al auge de la arqueología preventiva, se ha venido constatando una renovación importante de los datos cerámicos en el departamento de Bretaña, especialmente tras el descubrimiento de contextos domésticos del período del Bronce antiguo. Los hallazgos permiten disponer actualmente de contextos cerrados y bien fechados, propicios para la implementación de un enfoque tecnológico. Gracias a lo anterior se han podido integrar nuevos corpus domésticos a la reflexión general, tanto desde un punto de vista tipocronológico, como en el plano de las dinámicas culturales y de las redes de intercambio establecidas a escala de la fachada atlántica, en particular a través de fenómenos de adopción, copia e imitación

Internal 3D Printing of Intricate Structures

International audienceAdditive technologies are increasingly used in Cultural Heritage process , for example in order to reproduce, complete, study or exhibit artefacts. 3D copies are based on digitization techniques such as laser scan or photogramme-try. In this case, the 3d copy remains limited to the external surface of objects. Medical images based digitization such as MRI or CT scan are also increasingly used in CH as they provide information on the internal structure of archaeological material. Different previous works illustrated the interest of combining 3D printing and CT scan in order to extract concealed artefacts from larger archaeological material. The method was based on 3D segmentation techniques within volume data obtained by CT scan to isolate nested objects. This approach was useful to perform a digital extraction, but in some case it is also interesting to observe the internal spatial organization of an intricate object in order to understand its production process. We propose a method for the representation of a complex internal structure based on a combination of CT scan and emerging 3D printing techniques mixing colored and transparent parts. This method was successfully applied to visualize the interior of a funeral urn and is currently applied on a set of tools agglomerated in a gangue of corrosion

Preservative Approach to Study Encased Archaeological Artefacts

International audienceWe propose a workflow based on a combination of computed tomography, 3D images and 3D printing to analyse different archaeological material dating from the Iron Age, a weight axis, a helical piece, and a fibula. This workflow enables a preservative analysis of the artefacts that are unreachable because encased either in stone, corrosion or ashes. Computed tomography images together with 3D printing provide a rich toolbox for archaeologist work allowing to access a tangible representation of hidden artefacts. These technologies are combined in an efficient, affordable and accurate workflow compatible with Preventive archaeology constraints

Die typochronologische Analyse erlaubt es, dieses Mobiliar in die in Ostfrankreich gut vertretene späte Spätbronzezeit IIb einzuordnen. Dieser Artikel gehört zu einer Reihe kleiner Monographien, die uns ermöglichen wird, an der Feinperiodisierung dieser mittleren Phase der Spätbronzezeit im Departement Yonne zu arbeiten

From medical imaging to virtual reality for archaeology

The IRMA project aims to design innovative methodologies for research in the field of historical and archaeological heritage based on a combination of medical imaging technologies and interactive 3D restitution modalities (virtual reality, augmented reality, haptics, additive manufacturing). These tools are based on recent research results from a collaboration between IRISA, Inrap and the company Image ET and are intended for cultural heritage professionals such as museums, curators, restorers and archaeologists.Comment: in French languag
