The museum’s fourth floor housed over thirty sculptures by Markus Raetz (1941, Büren an der Aare). On the third floor, approximately fifty photocopies of preparatory drawings for a sculpture installed in a Genevan public square were displayed. Since the mid-1960s, Raetz has been developing an oeuvre based on perception and language that involves the viewer as they move around the works. By making use of crude, or at times amusing, figurations, he aspires above all to confuse the processes of perception and the mechanisms of recognition. Images go through multiple deviations and ambiguities as they are transformed from one object into another, asking the viewer to apply their skill of visual association. For Raetz, the question of the line, of what it determines in the sense of form and substance, is central. He often transposes images from the surface and traces them in space, thus generating forms that imply a particular point of view.
