Dominique Gonzalez-Foerster created the installation TH.2058 in 2008 in Tate Modern, London. It transported us to 2058, to the middle of a catastrophic flood, and evacuees found shelter in the gallery’s Turbine Hall. Tate Modern became a place of welcome for visitors who could lie on bunk beds as if they were refugees. In the exhibition Prima Materia, Gonzalez-Foerster took up this same idea. In the museum’s cloakroom, in a very cold space, infinte drops of water seem to fall into a bucket. The work, called Raining, can’t be seen and can’t be touched. Isn’t that surreal? A work that doesn’t exist? No, because it can be heard. A leak? Rain? A joke? It depends on our imagination. The visitor plays a central part in this work. It’s up to us to try to complete it. The artist creates an impression and we, with our imagination, are left to invent a story and imagine what has happened.
