The Nature in the volcanic region of Auvergne has something definitely sacred. It seems to be invisibly linked with the idea of art. Our approach is to search this specific nature in order to let the fear, the mystery, the metaphysical and spiritual questioning appear from the volcanic memory. A gigantic skeleton has arisen from these excavations of the Puy de Serveix summit. It draws a backbone along the peak of the mountain. Though it recalls the shape of a mammouth, its dimension – almost 200 meters long – exceeds the biggest dinosaur’s skeleton ever discovered. It belongs to an unknown specie. This discovery is a poetic and phantasmagorical interpretation of this specific natural environment. The idea is to set up an enigma within the landscape creating a deep impact upon the spectators’ imagination. He will be driven to search the depth and the mystery of our origins.
