Anne Baldassari, director of the Picasso Museum in Paris, evokes the Cubist revolution. From the Cubist landscapes of Horta, through the papers pasted together and presenting side by side paintings of the same theme, Anne Baldassari makes us understand the radical break that Picasso has introduced in the history of Painting since the Renaissance. By concentrating on restoring the volume on a flat surface without recourse to the artifices of illusion, Picasso renews our gaze on Painting.
