Galland's version provoked a spate of pseudo-Oriental imitations. At the same time, some French writers began to parody the style and concoct far-fetched stories in superficially Oriental settings. These tongue-in-cheek pastiches include Anthony Hamilton's "Les quatre Facardins" (1730), Crébillon's "" (1742) and Diderot's "Les bijoux indiscrets" (1748). They often contained veiled allusions to contemporary French society. The most famous example is Voltaire's "Zadig" (1748), an attack on religious bigotry set against a vague pre-Islamic Middle Eastern background. The English versions of the "Oriental Tale" generally contained a heavy moralising element, with the notable exception of William Beckford's fantasy "Vathek" (1786), which had a decisive influence on the development of the Gothic novel. The Polish nobleman Jan Potocki's novel "Saragossa Manuscript" (begun 1797) owes a deep debt to the "Nights" with its Oriental flavour and labyrinthine series of embedded tales.
