Twelve Waves: the simple title hints at the number, but not the kind of waves that Jörg Gläscher presents with this book. Physically, a wave is a spatially propagating periodic oscillation, or a disturbance of equilibrium. Gläscher's “waves” are the opposite of this definition. They are “standing” waves created from broken and found wood, sculptures built in the forest. These wooden waves are expression and result of the long phases of unaccustomed imposed silence, of reflection, of doubt and of uncertainty.
