For his second MAMCO exhibition, Pierre Vadi (1966, Sion), in collaboration with architect Christian Dupraz, created an installation that occupied all the rooms on the fourth floor, in which architecture and sculpture blended together to produce a hybrid form. With no openings to the outside, the somber-walled rooms were organized like a dense, homogenous structure, a “nerve center” in which visitors lost all sense of direction. Sculptural pieces were sometimes revealed to the eye, sometimes camouflaged, adding to the sense of disorientation. From a heavenly vault to resin animals, each object was a decoy concealing an intrigue, playing on its relationship with reality and its ability to evoke the imaginary, resisting any unequivocal, immediate interpretation. As a result, visitors could construct multiple narratives to weave various possible paths through the exhibition.
