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 reÌaliseÌ en 1994 sur la commune de Passy (Yonne), au lieu-dit «Richebourg Ouest», a reÌveÌleÌ une fosse treÌs riche en mobilier attribuable aÌ l'eÌtape moyenne du Bronze final.

Constantes et variations autour dâun modĂšle
Depuis les annĂ©es 2000 avec lâessor de lâarchĂ©ologie prĂ©ventive, on constate, en Bretagne, un renouvellement important des donnĂ©es cĂ©ramiques notamment avec la mise au jour de contextes domestiques du Bronze ancien. Ces dĂ©couvertes permettent, aujourdâhui, de disposer de contextes clos et bien datĂ©s, propices Ă la mise en place dâune approche technologique. Cette approche permet dâintĂ©grer les nouveaux corpus domestiques Ă la rĂ©flexion gĂ©nĂ©rale dâun point de vue typochronologique, mais Ă©galement au plan des dynamiques culturelles et des rĂ©seaux dâĂ©changes entretenus Ă lâĂ©chelle de la façade atlantique, tout particuliĂšrement au travers des phĂ©nomĂšnes dâemprunts, de copies et dâimitations.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 arqueologĂa preventiva, se ha venido constatando una renovaciĂłn importante de los datos cerĂĄmicos en el departamento de Bretaña, especialmente tras el descubrimiento de contextos domĂ©sticos del perĂodo del Bronce antiguo. Los hallazgos permiten disponer actualmente de contextos cerrados y bien fechados, propicios para la implementaciĂłn de un enfoque tecnolĂłgico. Gracias a lo anterior se han podido integrar nuevos corpus domĂ©sticos a la reflexiĂłn general, tanto desde un punto de vista tipocronolĂłgico, como en el plano de las dinĂĄmicas culturales y de las redes de intercambio establecidas a escala de la fachada atlĂĄntica, en particular a travĂ©s de fenĂłmenos de adopciĂłn, copia e imitaciĂłn
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 spĂ€te SpĂ€tbronzezeit IIb einzuordnen. Dieser Artikel gehört zu einer Reihe kleiner Monographien, die uns ermöglichen wird, an der Feinperiodisierung dieser mittleren Phase der SpĂ€tbronzezeit 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
