Polychromie médiévale et photogrammétrie 3D : la restitution des couleurs d’origine d’un ange du portail Royal (vers 1250) de la cathédrale de Bordeaux

Abstract : Sculpted around 1240/50, the Royal portal constitutes the main entrance to the cathedral of Bordeaux. The recent restoration (2011-2013) discovered beneath a modern ochre distemper significant rests of the original 13th century polychromy, concentrated in the tympanum and the archivolts. In order to obtain a reliable idea of what the sculptures originally looked like, three of the statues of the Royal portal, the polychromy of which is well preserved, have been digitalized by photogrammetry, and their 3D model has been coloured on the evidence of the results of physico-chemical analyses. One of these three statues/ models is presented here in detail.
