Fondly recalled for his sly novels and plays, Denis Diderot (1713-84) made his greatest contribution through the compilation of the Encyclopédie, a pioneering collection of scientific and philosophical information. This series of books was also lavishly illustrated, and its engravings provide the 50 coloring pages here. Ready for your pens, pencils, or markers, here are images of exotic birds, frogs, mollusks, writing quills, and elegant 18th-century interiors.
