Ali Baba and the Forty Thieves

"Ali Baba and the Forty Thieves" (Arabic: علي بابا والأربعون لصا) is a folk tale in Arabic added to the One Thousand and One Nights in the 18th century by its French translator Antoine Galland, who heard it from Syrian storyteller Hanna Diyab. As one of the most popular Arabian Nights tales, it has been widely retold and performed in many media across the world, especially for children (for whom the more violent aspects of the story are often removed).

In the original version, Ali Baba (Arabic: عَلِيّ بَابَا, romanized: ʿAliyy Bābā) is a poor woodcutter and an honest person who discovers the secret treasure of a thieves' den, and enters with the magic phrase "open sesame". The thieves try to kill Ali Baba while his rich and greedy brother Cassim (Arabic: قاسم Qāsim, sometimes spelled 'Kasim' or 'Qasim') tries to steal the treasure for himself, but Ali Baba’s faithful slave-girl Morgiana (Arabic: مرجانة Murjāna) foils their plots. His son marries her, and Ali Baba keeps the secret of the treasure.

Textual history

The tale was added to the story collection One Thousand and One Nights by one of its European translators, Antoine Galland, who called his volumes Les Mille et Une Nuits (1704–1717). Galland was an 18th-century French Orientalist who heard it in oral form from a Syrian Maronite story-teller called Hanna Diyab, who came from Aleppo in modern-day Syria and told the story in Paris. In any case, the earliest known text of the story is Galland's French version. Richard F. Burton included it in the supplemental volumes (rather than the main collection of stories) of his translation (published as The Book of the Thousand Nights and a Night).

The American Orientalist Duncan Black MacDonald discovered an Arabic-language manuscript of the story at the Bodleian Library; however, this was later found to be a counterfeit.
