Photographic, the work of Philippe Durand encompasses the world in a moving geography, on a variable scale. A large part of his work focuses on public space, on the traces of expression that can be found there, self-generated collages, graffiti and stratifications, objects placed and moved. Considering the Vallée des Merveilles (Mercantour national park) as an open-air proto-museum, without an artist, without a curator, without an audience or communication, the artist makes it the place for the development of his work, in a new spatial and temporal dimension. Dominated by Mont Bégo, classified as a historic monument since 1989, the Vallée des Merveilles, at an altitude of 2,500 meters, is home to an exceptional archaeological heritage, thousands of engravings made around 3,000 BC. This open-air sanctuary appears dedicated to a “primordial divine couple”, the earth goddess and the bull god. Spared by its difficulty of access, the site nevertheless contains graffiti that have appeared over the centuries, due to shepherds, soldiers, travelers, etc. Although formally prohibited since 1954, new inscriptions continue to appear alongside engravings dating from the Bronze Age. Philippe Durand's project consists of documenting both these inscriptions and certain engraved rock blocks in order to restore the latter in the form of inflatable sculptures, that is to say objects used more in amusement parks by the mass leisure industry than in a museum context. It is a question of recreating a “copy of the original”, of recomposing a topography of the place, and of comparing in the same space, inflatables, films and photographs made on site.
