Storming of the Bastille
Following the Storming of the Bastille on 14 July 1789, Sade's prison writings disappeared (Sade had been moved to Charenton on 4 July), the manuscript of the Dialogue among them. However, it survived in private collections and was sold on at auction a number of times during the nineteenth century. On 6 November 1920 it was bought by Maurice Heine at an auction at the Hôtel Drouot, Paris, and he oversaw its publication in France for the first time in 1926 in a limited edition of 500 copies for which he wrote an introduction.
