Collections of fairy tales called "One Thousand and One Nights," which are sparingly mentioned by medieval Arab writers, unfortunately, have not survived to this day. We can only assume that in composition these collections of fairy tales, apparently, differed from each other, they had only the title and the fairy tale-frame in common. The first "suppliers" of material for them were professional folk storytellers, whose stories were originally recorded under dictation with almost shorthand accuracy, without any literary processing. Subsequently, these records came to booksellers, who subjected the text of the fairy tale to some literary processing. Each fairy tale was considered at this stage not as an integral part of the collection, but as a completely independent work.
