There are a range of women not represented in the Western fairy tale tradition. Husband-beaters are particularly interesting, as well as male pederasts. Children are often told in The Arabian Nights, "This man likes to abduct boys, be careful of him." These issues are explored through the medium of the stories, but actually the architecture of the book is such that there are many examples of women who are loyal, brave, devoted - especially to their lovers.

Scheherazade, of course, was always in the back of my mind, because she's also a storyteller identified as female who tells a lot of anti-female stories. There's a parade in The Arabian Nights of sorceresses, adulteresses, ghouls, sirens, harridans.

The female form provides the solution in which the essence itself is held; she is passio, and acted upon, the male is actio, the mover.

The tripartite structure - so you remember the third brother, second brother, first brother, or the first dervish, second dervish, and third dervish. This is very like embroidering a cloth, as you have to know where you are with the knots.

The model of the educational Kalila Wa-Dimna. These are books of instruction to rulers and humans. The stories unfold a range of human psychology, a vast range of human psychology. The Sultan is being moved from his narrow and bigoted position into a wider, more subtle, more nuanced understanding of human experiences.

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.

The more one knows fairy tales the less fantastical they appear; they can be vehicles of the grimmest realism, expressing hope against all the odds with gritted teeth.
