The first printed version of the famous Tales of Margaret of Navarre, issued in Paris in the year 1558, under the title of “Histoires des Amans Fortunez,” was extremely faulty and imperfect. It comprised but sixty-seven of the seventy-two tales written by the royal author, and the editor, Pierre Boaistuau, not merely changed the order of those narratives which he did print, but suppressed numerous passages in them, besides modifying much of Margaret’s phraseology. A somewhat similar course was adopted by Claude Gruget, who, a year later, produced what claimed to be a complete version of the stories, to which he gave the general title of the _Heptameron_, a name they have ever since retained. Although he reinstated the majority of the tales in their proper sequence, he still suppressed several of them, and inserted others in their place, and also modified the Queen’s language after the fashion set by Boaistuau. Despite its imperfections, however, Gruget’s version was frequently reprinted down to the beginning of the eighteenth century, when it served as the basis of the numerous editions of the _Heptameron_ in _beau langage_, as the French phrased it, which then began to make their appearance. It served, moreover, in the one or the other form, for the English and other translations of the work, and down to our own times was accepted as the standard version of the Queen of Navarre’s celebrated tales. Although it was known that various contemporary MSS. were preserved at the French National Library in Paris, no attempt was made to compare Gruget’s faulty version with the originals until the Société des Bibliophiles Français entrusted this delicate task to M. Le Roux de Lincy, whose labours led to some most valuable discoveries, enabling him to produce a really authentic version of Margaret’s admired masterpiece, with the suppressed tales restored, the omitted passages reinstated, and the Queen’s real language given for the first time in all its simple gracefulness. It is from the authentic text furnished by M. Le Roux de Lincy that the present translation has been made, without the slightest suppression or abridgment. The work moreover contains all the more valuable notes to be found in the best French editions of the _Heptameron_, as well as numerous others from original sources, and includes a _résumé_ of the various suggestions made by MM. Félix Frank, Le Roux de Lincy, Paul Lacroix, and A. de Montaiglon, towards the identification of the narrators of the stories, and the principal actors in them, with well-known personages of the time. An Essay on the _Heptameron_ from the pen of Mr. George Saintsbury, M.A., and a Life of Queen Margaret, are also given, as well as the quaint Prefaces of the earlier French versions; and a complete bibliographical summary of the various editions which have issued from the press.
