The seated "Moses" of Michelangelo, the "Venus de Milo" and the "Venus of Arles", a bust of Caracalla in armour, as well as an Athena Helmet. It's like walking around the greatest museums in just a few hours and a few steps! Collaborating with the moulding workshop of the Réunion des Musées Nationaux - Grand Palais (RMN), Daniel Arsham reproduces here emblematic sculptures on the same scale, to which he subjects them to erosion and then his crystallisation process, as if they were the result of an archaeological exploration. In the course of his various works, the artist has worked on memory, on the vestiges of the past, on the transformation of objects into artifacts. This new series experiences the timelessness of certain symbols. These works have transcended their status as mere objects of art to become part of our collective identity. The artist's process of crystallization is very appropriate here, reinforced by the museography of the exhibition, which takes up the codes of the museum and questions the valorization of art objects. Thus staged, this exhibition questions our relationship with time. It evokes the past, speaks of the present and questions the future.
