The present edition is an exact reproduction of that edited by my father, with my great-uncle's final corrections, and published by Mr. John Murray in 1859. Several reprints of that edition have testified to the continued popularity of the work, and the necessity for the present issue shows that an acquaintance of nearly half a century has not yet wearied the public of the standard translation of the _Thousand and One Nights_. The secret of Mr. Lane's success is to be found partly in the instinctive sympathy for the spirit of the East, which enabled him faithfully to reproduce the characteristic tone of the original, and partly in the rich store of illustrations of oriental life and thought contained in his Notes. In the various cheap versions, based upon Galland's French paraphrase, the Eastern tone and local colour is wholly wanting; and the peculiarities of life and manners, which contrast so markedly with those of the West, are left unnoted and unexplained. Such versions may serve in an inadequate degree to make the Arabian Nights known to those who care only for the bare stories; but educated readers, who are capable of something more than the mere enjoyment of the romance, and desire to understand the character and habits of the actors and the spectators, find in Mr. Lane's translation, and in his only, a complete satisfaction of their want. It is not merely a scholar's edition, though no oriental student can afford to be without it; but beyond this narrow circle it has ever appealed to the wide audience that cares to know the famous books of the world in their most perfect and faithful reflections.
