The legend of three weeks' composition comes from Voltaire's own correspondence, and it is almost certainly exaggerated in the other direction: meant to diminish the book, to make it sound like a jeu d'esprit rather than a considered assault. Whether three weeks or three months, the result was a work so tightly constructed — its picaresque cruelties accumulating without pause, its famous closing image of the garden stripped of all metaphysical comfort — that the speed claim reads less as confession than as another layer of disavowal. Voltaire denied Candide the way a man denies a fire he has just set: gesturing at the smoke while still holding the match.

Voltaire published one of the eighteenth century's most dangerous books, then spent years insisting he had nothing to do with it.

Candide, ou l'Optimisme appeared in January 1759 under a fictitious imprint — "Londres" on the title page, Geneva in fact — attributed to one "Docteur Ralph," a name Voltaire had invented. The book was printed by Gabriel Cramer, the Geneva publisher who handled much of Voltaire's real work, which made the disguise transparently thin from the start. Within weeks of publication, the Petit Conseil of Geneva banned it on grounds of irreligion and sedition. Paris followed. The Sorbonne condemned it. Voltaire, writing from his estate at Les Délices just outside Geneva, denied authorship with elaborate theatrical indignation — calling the book a trifle, unworthy of his attention, clearly the work of some lesser pen.
Nobody believed him. The prose style was unmistakable, the targets too precise: Leibnizian optimism, the Lisbon earthquake of 1755, the Seven Years' War, the Jesuit missions in Paraguay, judicial torture. A text that skewered everything in French institutional life with that particular velocity could only have come from one address. Cramer's first printing — spread across several simultaneous editions in Geneva and Paris — sold out almost immediately, and at least seventeen editions appeared before the year was out.
