A film consisting of four parts, which attempts to reduce the illusionist space that cinema inherits from the perspective devices of classical painting to the two sole dimensions of the screen, through means specific to the filmic medium. The motif of the window serves as serialized material, since it is by imagining itself like a window (Alberti, Dürer) that the Quattrocento painting was able to construct its perspective and illusionist space. Production : Visual Arts Insttute of Orléans.
