Although the stories are very present in my book, and very present in my mind, what I was most interested in was the question of why it had attracted such a following in the 18th Century. It's less mysterious that it attracted a following in the Romantic period, and in the 19th Century, but the early 18th Century when the Rationalists fell in love with it...that was mysterious. What I wanted to look at was the forms of enchantment.

The price the Virgin demanded was purity, and the way the educators of Catholic children have interpreted this for nearly two thousand years is sexual chastity. Impurity, we were taught, follows from many sins, but all are secondary to the principal impulse of the devil in the soul--lust.

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.

I do think that this represents a kind of shift towards myth, a recovery of myth, largely through the popularity of writers like Philip Pullman. Somehow myths have returned as a serious subject. It used to be scorned...really scorned. It was part of a nursery tradition, and it was also rather tainted - but not in an immovable way - by the association with right-wing ideologies after the World Wars.

The stories are most often about justice. In her stories, those who commit injustice, or act tyrannically, come to no good. They are punished.

The vocabulary of pleasure depends on the imagery of pain.

True to their history, the English are very domineering and have manipulated it in different ways. I wouldn't say that there was an original, but there is a lot of expurgation in some of the Victorian translations, and there's a lot of additional salacious nonsense in some of them, too. I also like the early French one, much-derided for being fanciful but which is actually very elegantly done. It's very big, very capacious.
