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

Our purpose is to contextualise the demand of habits of military orders in late Old Regime Spain and Portugal. To disentangle the question from a nobiliary perspective which we suspect has been unduly inflated, we determine the factors which laid behind a similar process, taken in a different context: the demand of decoration expressed by the French colonial society of Tunisia at the beginning of the XXth Century. Such a study stresses the central paper of factors which Iberian historiographies usually do not take into account. Tentativa para poner en perspectiva la demanda de hábitos de ordenes militares en los países ibéricos a fines del Antiguo Régimen, determinando los parámetros de la demanda de condecoraciones en la sociedad colonial francesa de la Regencia de Túnez a fines del siglo XIX. La descripción de los fenómenos que se dan en lo segundo abre pautas de investigación para el primer problema, al sacarlo de la problemática tradicional del ennoblecimiento que resulta obivamente reductora.

Le site gallo-romain de Sanxay, l’un des plus spectaculaires du Poitou, offre encore aujourd’hui un vaste théâtre, des thermes imposants, un sanctuaire au plan en forme de croix grecque. Les sondages récents n’ont révélé que peu de vestiges des revêtements peints ou stuqués. Mais dans les années 1880, les travaux du père Camille de La Croix en avaient fourni un certain nombre, en place ou fragmentaires. L’exploitation des archives (dessins et notes), des publications anciennes et de vestiges peu connus dans les réserves du musée Sainte-Croix à Poitiers nous a permis d’avancer un peu l’enquête : la décoration de quelques salles thermales nous est mieux connue, et le décor à réseau d’une voûte a pu être restitué. The Gallo-Roman site of Sanxay is one of the most spectacular in Poitou, with a vast theatre, an impressive baths complex, and a sanctuary with the plan of a Greek cross. Recent investigation has revealed that only a few painted or stuccoed linings have survived but in the 1880s the studies carried out by Père Camille de La Croix turned up a certain number, either in situ or fragmentary. Consultation of drawings and notes, ancient publications and little-known remnants in the deposits of the musée Sainte-Croix in Poitiers has furthered our knowledge : we now have a better understanding of the decoration in several rooms of the baths complex and the repeat-pattern decoration of a vault has been reproduced. Der gallo-römische Fundplatz von Sanxay ist einer der spektakulärsten des Poitou. Noch heute sind ein großes Theater und imposante Thermen zu sehen sowie ein Heiligtum, dessen Grundriss ein griechisches Kreuz beschreibt. Die neueren Sondierungsgrabungen haben zwar kaum Reste von Wandmalereien oder Stuck geliefert, doch bei den Ausgrabungen des Paters Camille de La Croix um 1880 waren solche Dekore zutage gekommen, entweder in situ oder in Form von Fragmenten. Die Auswertung der Archive (Zeichnungen und Notizen), alter Publikationen und recht unbekannter Reste in den Reserven des Musée Sainte-Croix in Poitiers haben die Untersuchung etwas weitergebracht : über die Ausschmückung einiger Säle der Thermen sind wir nun besser informiert, zudem konnte das Gitterwerk eines Gewölbes rekonstruiert werden.

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.
