information about Persia, must of course be recognized; he owned the two-volume edition of 1687 and purchased the extended edition in ten volumes in 1720. To a lesser degree, he drew on the Voyages of Jean-Baptiste Tavernier and Paul Rycaut, not to mention many other works which his vast library afforded him. Everything having to do with contemporary France or Paris, on the other hand, comes essentially from his own experience, or from conversations of anecdotes related to him. Various aspects of the book are doubtless indebted to particular models, of which the most important is Giovanni Paolo Marana’s L’Espion dans les cours des princes chrétiens (Letters Writ by a Turkish Spy), widely known at the time, even though Montesquieu’s characters obviously are Persians and not Turks. While the great popularity of Antoine Galland’s Mille et Une Nuits (The Thousand and One Nights) contributes, as do the Bible and the Qu’ran, to the general ambiance of oriental subjects, in fact it has almost nothing in common with Lettres persanes. Critical history Lettres persanes was an immediate and durable sensation and was often imitated, but it has been diversely read over time. Until the middle of the twentieth century, it was the "spirit" of the Regency which was largely admired, as well as the caricature in the classical tradition of La Bruyère, Pascal and Fontenelle. No one thought to attach it to the novelistic genre. The Persian side of the story tended to be considered as a fanciful decor, the true interest of the work lying in its factitious "oriental" impressions of French society, along with political and religious satire and critique. In the 1950s began a new era of studies based on better texts and renewed research. Particularly important were the extensively annotated edition by Paul Vernière for Classiques Garnier, long the standard edition, and the findings of Robert Shackleton regarding its use of Muslim chronology; also new perspectives by Roger Mercier, Roger Laufer, and Pauline Kra, which put new focus on the work's unity and integrated the seraglio into its overall meaning. Others who have followed have looked into the ramifications of epistolary form (Rousset, Laufer, Versini), the structure and meaning of the seraglio (Brady, Singerman), and Usbek's purported contradictions. In recent decades it has been religion (Kra) and especially politics (Ehrard, Goulemot, Benrekassa) which predominate, with a progressive return to the role of the seraglio with all its
