Jean-Michel Othoniel is known for his coloured glass bead sculptures. The most famous is undoubtedly "Le Kiosque des Noctambules", which overlooks the entrance to the Palais Royal - Musée du Louvre metro station. This Murano glass and aluminium structure was commissioned in 2000 by the RATP to mark the passage into a new millennium. For this carte blanche at the Petit Palais, the artist once again invades the public space by taking the visitor right into the street. The exhibition begins on the Great Staircase, where a river of blue glass bricks is reflected. It is also an opportunity to highlight Jean-Michel Othoniel's new way of working. For a few months now, he has been living in a huge studio in Montreuil, simply called Othoniel studio, which includes offices, a hangar, a bookshop dedicated to the artist and his companion, the plastic artist Johan Creten, as well as a café-restaurant. This hybrid space remains above all the artist's studio, where he stores and assembles his sculptures on site. A radical change of scale is evident in his latest productions, which are becoming increasingly monumental and architectural. Seventy of them are on display in this poetic exhibition that reflects the unique world of Jean-Michel Othoniel. The Théorème de Narcisse, which he specially invented, is a man-flower whose simple reflection also mirrors that of the world around him. Blown glass has always been, and will remain, present in the artist's work.
