"Money. You don't know where it's been,
But you put it where your mouth is.
And it talks." (Money, by Dana Gioia)

The history of money stretches back some 11,000 years. There have been certain key moments in its development and each essay tells their story and the resonance that these revolutionary blips have had ever since.

1. Cows - round about 9,000BC cattle were first domesticated. Soon after they became units of exchange and thus the idea of money was born: cows became cash on legs. And they still are - in certain parts of Africa commodities (especially brides) are priced in cows. Professor Keith Hart explores the early examples of money as part of an economy of living persons and things.
