The Commentaires sur Corneille is a work of literary criticism by the French Enlightenment writer and philosopher Voltaire, collecting and analysing the dramatic works of Pierre Corneille (1608–1684).
 It was first published in 1764, printed in Geneva in twelve volumes.
 A second edition, published ten years later, added extensive critical commentary, reflecting changes in Voltaire's attitude to Corneille and to criticism.
 It was Voltaire's largest ever work of critical commentary, described by the author as a distillation of his fifty years of experience in theatre.
 Though very influential in the late eighteenth century, it was seen more negatively from 1800 onwards, as critics questioned the fairness of Voltaire's commentary and his motives.
Boulevard Voltaire is a well-known boulevard in the 11th arrondissement of Paris.
 It was created by Baron Georges-Eugène Haussmann during the reign of French emperor Napoleon III.
 Originally named Boulevard du Prince-Eugène, it was renamed Boulevard Voltaire on 25 October 1870 in honour of the French Enlightenment writer, historian, and philosopher Voltaire.

 Voltaire crater is one of two named features on Deimos, the other being Swift crater.

François-Marie Arouet (] ; 21 November 1694 – 30 May 1778), known by his "nom de plume" Voltaire ( ; ] ), was a French Enlightenment writer, historian, and philosopher famous for his wit, his attacks on the established Catholic Church, and his advocacy of freedom of religion, freedom of speech, and separation of church and state.
Marie Thérèse Rodet Geoffrin (26 June 1699 – 6 October 1777) was a French salon holder who has been referred to as one of the leading female figures in the French Enlightenment.
 From 1750–1777, Madame Geoffrin played host to many of the most influential Philosophes and Encyclopédistes of her time.
 Her association with several prominent dignitaries and public figures from across Europe has earned Madame Geoffrin international recognition.
 Her patronage and dedication to both the philosophical Men of Letters and talented artists that frequented her house is emblematic of her role as guide and protector.
 In her salon on the rue Saint-Honoré, Madame Geoffrin demonstrated qualities of politeness and civility that helped stimulate and regulate intellectual discussion.
 Her actions as a Parisian salonnière exemplify many of the most important characteristics of Enlightenment sociability.
Voltaire is the pen name of French Enlightenment writer, historian, and philosopher François-Marie Arouet.
Perfect is the enemy of good is an aphorism, an English variant of the older "better is the enemy of good", which was popularized by Voltaire in French form.
 Alternative forms include "the perfect is the enemy of the good", which more closely translate French and earlier Italian sayings, or "[the] perfect is the enemy of [the] good enough".
 Similar sentiments occur in other phrases, including from English, and are all attested since around 1600.
Le Mondain ("The Worldling" or "The Man of the World") is a philosophical poem written by French enlightenment writer and philosopher Voltaire in 1736.
 It satirises Christian imagery, including the story of Adam and Eve, to defend a way of life focused on worldly pleasure rather than the promised pleasure of a religion's afterlife.
 It opposes religious morality and especially the teaching of original sin.
 Its points echo Voltaire's prose works "Lettres philosophiques" and "Remarques sur Pascal".
 Voltaire noted a trend against using poetic forms to make philosophical arguments, and wrote "Le Mondain" in deliberate opposition to this trend.

La Henriade is an epic poem of 1723 written by the French Enlightenment writer and philosopher Voltaire.
 According to Voltaire himself, the poem concerns and was written in honour of the life of Henry IV of France, and is a celebration of his life.
 The ostensible subject is the siege of Paris in 1589 by Henry III in consort with Henry of Navarre, soon to be Henry IV, but its themes are the twin evils of religious fanaticism and civil discord.
 It also concerns the political state of France.
 Voltaire aimed to be the French Virgil, outdoing the master by preserving Aristotelian unity of place—a property of classical tragedy rather than epic—by keeping the human action confined between Paris and Ivry.
 It was first printed (under the title "La Ligue") in 1723, and reprinted dozens of times within Voltaire's lifetime.
