Many of the enchanted things in the book are lamps, carpets, sofas, gems, brass rings. It is a rather different landscape than the fairy tale landscape of the West. Though we have interiors and palaces, we don't have bustling cities, and there isn't the emphasis on the artisan making things. The ambiance from which they were written was an entirely different one. The Arabian Nights comes out of a huge world of markets and trade. Cairo, Basra, Damascus: trades and skills.

The tales are quite hard to remember and I found that going back to it between bouts of writing fiction, I was having to retrace my steps quite a lot, because the stories are very intricate and the material is elusive, and possibly with age, my memory is not as malleable as it used to be.

I have many, many editions of the books, and they are all rather different. In the end, the one I used was the most recent French translation. French suits the tales well, and it's a beautiful translation. The Italian one is good as well... English has fallen short.

It seemed to me to be a parable of the exchange of goods, rather Marxist in some ways, in the new world of global forces. What the forgers do is write the brand name to try and change it, and it works! Loads of people buy fake Prada handbags, or Chanel sunglasses; they've been changed. They have been truly, really changed.

There's a whole slew of wonderful speculation of flying in a fanciful way. Gulliver is one of the central examples; Swift has the hum of Arabian Nights in his ear with Gulliver's Travels. The difference is in scale - Gulliver as a kind of Sinbad kind of figure, the way he is picked up and carried. Just to finish up with Scheherazade, I do think that The Arabian Nights could be considered as a great book on women's position in the world.

I think that a true economics thinker or a Marxist thinker would make nonsense of my argument, although I have given massive seminars and no one has demolished it so far. I did think that this idea from an artisanal and trading perception of the auratic quality of goods when they are given character and inscription, made the stories of phantasmic wealth read more powerfully in the 18th and 19th centuries than the stories of Cinderella's wealth, because they are conjured out of nothing by these magic means.

There is a theory, that I rather subscribe to. The frame story implies that if he doesn't change, she will kill him. It's all very complex and subtle. The story is about a woman who persuades a man in power to a different temper and attitude, and so it is about women's wiles, what women will get up to. She has a plan, she has a scheme.
