This claimed to be based on an older Egyptian manuscript (which has never been found). A major recent edition, which reverts to the Syrian recension, is a critical edition based on the fourteenth- or fifteenth-century Syrian manuscript in the Bibliothèque Nationale originally used by Galland. This edition, known as the Leiden text, was compiled in Arabic by Muhsin Mahdi (1984-1994). Mahdi argued that this version is the earliest extant one (a view that is largely accepted today) and that it reflects most closely a "definitive" coherent text ancestral to all others that he believed to have existed during the Mamluk period (a view that remains contentious). Still, even scholars who deny this version the exclusive status of "the only "real" Arabian Nights" recognize it as being the best source on the original "style" and linguistic form of the mediaeval work. In 1997, a further Arabic edition appeared, containing from the Arabian Nights transcribed from a seventeenth-century manuscript in the Egyptian dialect of Arabic. The first European version (1704–1717) was translated into French by Antoine Galland from an Arabic text of the Syrian recension and other sources. This 12-volume work, "Les Mille et une nuits, contes arabes traduits en français" ("The Thousand and one nights, Arab stories translated into French"), included stories that were not in the original Arabic manuscript. "Aladdin's Lamp", and "Ali Baba and the Forty Thieves" (as well as several other lesser-known tales) appeared first in Galland's translation and cannot be found in any of the original manuscripts. He wrote that he heard them from the Christian Maronite storyteller Hanna Diab during Diab's visit to Paris. Galland's version of the "Nights" was immensely popular throughout Europe, and later versions were issued by Galland's publisher using Galland's name without his consent. As scholars were looking for the presumed "complete" and "original" form of the Nights, they naturally turned to the more voluminous texts of the Egyptian recension, which soon came to be viewed as the "standard version". The first translations of this kind, such as that of Edward Lane (1840, 1859), were bowdlerized. Unabridged and unexpurgated translations were made, first by John Payne, under the title "The Book of the Thousand Nights and One Night" (1882, nine volumes), and then by Sir Richard Francis Burton, entitled "The Book of the Thousand Nights and a Night" (1885, ten volumes) – the latter was, according to some assessments, partially based on the former, leading to charges of plagiarism.
