Curated by Peggy Guggenheim Collection for Davide Groppi.Windows Open Simultaneously (1912, Robert Delaunay).This work is one of the “fragments of a rainbow” proposed by Delaunay in his Windows series, resulting from the scientific knowledge at the beginning of the Twentieth century about light and colour, an integral part of the author’s artistic journey.In Windows the reflection on light is at the centre of the artist’s work. A light that fragments reality, creating an iridescent rhythm that forces the eye to move constantly across the canvas, searching for an impossible point of reference.“Here, light is here revealed in all its truth”, written by Apollinaire, referring precisely to Delaunay’s work.
