    International audience; As with geography, ceramic decorations are essentially spatial organisations of features. Therefore, they should be analysed with spatial indexes. But spatial analyses, at the shard or the complete ceramic scale, are often difficult to set up, mostly because of the contiguity of graphical features.This paper presents a new method to record and analyse ceramic decoration. We use graph theory, with a GIS interface and Python programming, to analyse ceramic decoration in a bottom-up process. A priori definitions are minimal and only concern elementary units (morphological, graphical and plastic) which compose the ceramic.The studied corpus is composed of ceramic decorations belonging to the Mailhac I facies (Late Bronze Age), characterised by complex figurative compositions. Each decoration — complete or fragmented — is considered as a spatialized network (i.e. geometric graph). Graph theory provides tools to record and measure proximities between units and normalised indexes to compare different decorations, whatever their completeness. The GIS offers a graphic interface and ensures the correctness of spatial relationships between these units. The typology of these units is realised in a hierarchical oriented graph. This structure allows processes of generalisation (going up the tree) and specification (going down the tree), permitting comparison between units with different kinds of resolution and/or complexity. The method presented here can be used for other types of mediums(statuary, rock art, etc.).

    International audience; Decoration has long suffered from relative neglect in material culture studies, now more focused on the social and cognitive processes behind the object. It has been regarded either as devoid of meaning, with motif names being simply labels, or as imbued with major socio-cultural and religious significance. This chapter, covering the field of basketry in Borneo, examines the underlying, potentially complex, relations between a motif or pattern, the way it is named, the meaning of this name, and what it denotes, both as an immediate representation and as a vector of metaphorical, symbolic, mythological, or religious referents. It stresses the need to view culture at the local level, as the current product of a given community's unique history of internal evolution and external cultural and social interaction, with high variability among communities. It concludes that a local catalogue of motifs is the result of an ongoing ad hoc collective bricolage, with possibly some kind of hierarchy among various classes of motifs, but in which norms, rules, and coherent naming and reference systems remain elusive.

    International audience; Geographic information systems (GIS) have been used to study the Chauvet-Pont d’Arc Cave (Vallon-Pont-d’Arc, Ardèche) for over ten years, with the support of the Ministry of Culture’s Centre National de Préhistoire (CNP). Their use has facilitated the centralisation and description of data and metadata. The arrival of Web 2.0 today opens up new prospects for data acquisition in situ and makes an interdisciplinary information management possible. The WebSIG application at the Chauvet Cave is proposed as an operational response to new uses. The introduction of Geoweb tools in archaeological practices invites us to adopt a reflective approach so as to highlight their usefulness in the study of decorated caves.; Depuis plus d’une dizaine d’années, les systèmes d’information géographique sont utilisés pour l’étude de la grotte Chauvet-Pont d’Arc (Vallon-Pont-d’Arc, Ardèche) avec l’appui du Centre National de Préhistoire (CNP) du ministère de la Culture. Leur emploi a facilité la centralisation et la description des données et des métadonnées. L’arrivée du web 2.0 ouvre aujourd’hui de nouvelles perspectives d’acquisition in situ et rend possible une gestion interdisciplinaire de l’information. L’application du WebSIG à la grotte Chauvet est proposée comme une réponse opérationnelle à de nouveaux usages. L’introduction des outils du géoweb dans les pratiques archéologiques invite à mener une approche réflexive afin de mettre en évidence leur intérêt pour l’étude des grottes ornées.

    International audience; The aim of this study was to examine and document the wall paintings in theChâteau de Germolles. Situated in Burgundy, France, Germolles is the best preservedresidence of the Dukes of Burgundy and was listed as a monument ofnational importance in 1989.The medieval wall decoration of the Château de Germolles was rediscoveredunder the nineteenth-century plasters during World War II. Medieval accounts ofthe château provide a detailed list of the materials acquired to make the muraldecoration, but this list is incongruous when compared with the current appearanceof the paintings. The discrepancy between the archival and material evidence,and also the need to understand the complexity of the painting technique usedwere the main motivations for undertaking the case study described in this chapter.Imaging alongside more traditional examination techniques were utilized torecord and document the mural decoration. The objectives of the case study wereto distinguish the original materials from those applied during restoration, identifythose materials, and correlate them with the archives. We also tried to understandthe medieval painting techniques used and assess the condition of the paintingsand stabilization requirements. Finally we aimed to find a sustainable solution forthe management of the various types of data collected. Various techniques andinvestigations offered valuable insights into the materials and the painting techniqueused. To improve visitor experience, based on the information gained in thecourse of this study, a 3D virtual representation of the original decoration is currentlyproposed for display to the public visiting the Château de Germolles.
