Article: The first book printed in France, Epistolae ("Letters"), by Gasparinus de Bergamo (Gasparino da Barzizza), was published in Paris in 1470 by the press established by Johann Heynlin. Since then, Paris has been the centre of the French publishing industry, the home of some of the world's best-known writers and poets, and the setting for many classic works of French literature. Almost all the books published in Paris in the Middle Ages were in Latin, rather than French. Paris did not become the acknowledged capital of French literature until the 17th century, with authors such as Boileau, Corneille, La Fontaine, Moliere, Racine, several coming from the provinces, and the foundation of the Academie francaise. In the 18th century, the literary life of Paris revolved around the cafes and salons, and was dominated by Voltaire, Jean-Jacques Rousseau, Pierre de Marivaux, and Beaumarchais.
