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.

I do not think commodities are taken for granted. One of the convergences in time I noticed, and to me seemed very important, was the emergence of paper money. There had been permissionary notes, exchanging money by writing it, but there was no duplicated form of guaranteeing an exchange.

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.

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.

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.

When I was young, I did actually model and was much photographed by famous photographers. But I was always a bookworm.

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.
