There is humanist enterprise of the book, and amongst that there are many, many stories. And that is why at the end, when he says that the stories are so illuminating that they must be engraved and encased in gold and put in the palace library, the people who compile the book are telling us that this is a collection of human wisdom.

I used to retain information extremely fast, so perhaps it's hardening a bit and I don't take the impression as well as I used to. Instead of writing in free flight, I had to check on the stories all the time. So I have decided I better to do it while I am fresh!

Though it's marvelously entertaining, and I had fantastic fun writing the book, it's not terribly easily, the material, and it's not all that familiar...although we think it is familiar. The processes of the wonderful narratives are very intricate. It's about the charm - the spellbinding charm - of ingenuity, and it's not so easy to remember the plots or the structure or even the names.

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.

One of the metaphors of the book is the carpet. Not just the flying carpet, but the carpet as a woven surface in which many repetitions and motifs recur and mirror one another. This is very much reflected within the stories: they have borders within borders, repeated motifs which change. They have their feet in oral conventions, and for the mnemonics, the storyteller needs to have a structure in order to remember the stories.

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.
