In his work, Evariste Richer (*1969 in Montpellier) links his interest in the natural sciences and concepts of space and time, combining their manifestations like a chemist who is empirically testing reactions between elements. An alchemistic approach, for twelve years Richer’s work has been characterized by a world viewed in the light of its geological and cosmic elements and in which abstraction and formal simplicity are accompanied by the sublime. The works being presented in the exhibition Caesium reflect a wide variety ofphysical phenomena and play with the perception of time and space and their measures. Richer places the Remise in Braunschweig in spatial relation to his studio in Paris by the revelation of a Diazo printing serie at scale one of the windowpanes in his studio and using them to create a « mise en abime » of the facade of the Remise. They provide the viewer with a real point of reference for situating the exhibition in terms of a shift in perspective.
