The accurate reissue of Diderot and D'Alembert's Encyclopédie constituted an enormous challenge Franco Maria Ricci’s newborn publishing house: more than ten years of work were necessary to handcraft the eighteen volumes of illustrated plates, entries and essays (twelve volumes are dedicated to reproductions of all the illustrated plates of the Encyclopédie, five to the selected entries and one to scientific essays about the work). It was the love of the Enlightenment ideals that pushed Ricci towards this project which, despite initial fears, had great success. The format is the same as the Parisian original, which is exhibited in Ricci’s Collection.
