On the occasion of the exhibition Chagall: The Emissary of Light, which explores the importance of light and of stained-glass window in Marc Chagall' work, the Centre Pompidou–Metz has invited Ann Veronica Janssens to present a new triptych from her gaufrettes series. By an effect of absorption and diffusion of the light rays, these ribbed glass plates, which contain an overlay of different iridescent and colored filters, produce chromatic vibratory variations.
