sentences:  The Bastille's archives, recording the operation of the prison, had been scattered in the confusion after the seizure; with some effort, the Paris Assembly gathered around 600,000 of them in the following weeks, which form the basis of the modern archive.After being safely stored and ignored for many years, these archives were rediscovered by the French historian François Ravaisson, who catalogued and used them for research between 1866 and 1904.At the end of the 19th century the historian Frantz Funck-Brentano used the archives to undertake detailed research into the operation of the Bastille, focusing on the upper class prisoners in the Bastille, disproving many of the 18th-century myths about the institution and portraying the prison in a favourable light.
