This discovery exhibition proposes some original works (sculptures, engravings, books, stamps) and commented images of the most famous portraits of Diderot, made during his lifetime then in the nineteenth and twentieth century. Discover how Houdon, Rodin, Bartholdi, Picasso and many others imagined the philosopher. Realistically or heroically, intimately or socially, in dialogue or doubt, strong or fragile… , Diderot was imagined differently. Each representation tells a story: how the greatest artists imagined Diderot, how Diderot reacted to his own portraits, as the posterity of the great man is embodied over the centuries in painting, sculpture, engraving, stamps… to this day. Between physical and psychological portraits, the images of Diderot have contributed to build our collective imagination of the philosopher.
