Présentation abstract :
This paper aims at illustrating one aspect of the possible relations between art and science, focusing on a precise domain: landscape representations (paintings, engravings or old photos) and landscape evolution. More precisely it deals with scientific field work and artistic field work: which data useful for scientific geography may be extracted from paintings which were drawn in the field? This approach has long been developed by British researchers (Robin Mc Innes) and has recently been developed in the framework of the European Arch-Manche project. Our innovative contribution, which is presented here, deals concretely, with a corpus of ancient illustrations of the French Channel coast from which a study of coastal changes over the last centuries is proposed. According to an innovative methodology, the points of view chosen by the artists are re-localized and photos are taken from them. A first comparison of the pairs of images allows assessing the accuracy of artworks as objective source of knowledge. In a second time the diachronic study of images highlights landscape changes, which can be accredited thanks to old maps or writings. Different graphic methods (mashups, morphing …) are built in order to summarize these observations. Finally, scientific field works (such as paleosols dating) are planned to precisely study some specific geomorphological changes in order to illustrate the concept ofAccommodation Space.
