The exposition Illuminated treasures of Normandy (Trésors enluminés de Normandie) shows around one hundred medieval and Renaissance works of an almost forgotten collection of illuminated manuscripts and works. The works are kept in many different archives, libraries and private collections and are not open to the public. The exhibition gives an overview of the evolution and history of illumination, primarily meant for religious, scientific and didactic books, to be followed by the interest for these works in the nineteenth and twentieth centuries. Illumination changed as result of the printing press, but this was just a change of technique.
