The Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers, par une Société de Gens de lettres was published under the direction of Diderot, with 17 volumes of text and 11 volumes of plates between 1751 and 1772. Contributors included the most prominent philosophes: Voltaire, Rousseau, d’Alembert, Marmontel, d’Holbach and Turgot, to name only a few. These great minds (and some lesser ones) collaborated in the goal of assembling and disseminating in clear, accessible prose the fruits of accumulated knowledge and learning. Containing 72,000 articles written by more than 140 contributors, the Encyclopédie was a massive reference work for the arts and sciences, as well as a machine de guerre which served to propagate Enlightened ideas.
