French author of a voluminous body of poetry, criticism, history, and drama, Voltaire was probably best known for his comic yet philosophical fiction. Among his most notable works, his first dramatic tragedy, Oedipe (1718), was a tremendous success. His epic poem La Henriade (1723) celebrates the life of Henry IV of France. Zaire (1732) is a tragic love drama. Letters Concerning the English Nation (1733) offers a comparison between England and France that is favorable to England particularly for its religious tolerance. Le Siècle de Louis XIV (1751) celebrates the humanistic achievements during the era of that monarch's reign. Le Monde Comme Il Va, Vision De Babouc (1748) and Candide; ou, L'optimisme (1759) satirize overly naïve optimism. L'Ingénu (1767) offers social satire through a depiction of innocent simplicity in the "noble savage" vein.
