The scene in the small, stifling room is not hard to imagine: the scribe frowning, shifting in his seat as he tries to concentrate on the words of the woman in front of him. A member of one of the wealthiest families in Sippar, the young priestess has summoned him to her room to record a business matter. When she entered the temple, she explains, her parents gave her a valuable inheritance, a huge piece of silver in the shape of a ring, worth the equivalent of 60 months' wages for an estate worker. She has decided to buy land with this silver. Now she needs someone to take down a few details. Obediently, the scribe smooths a wet clay tablet and gets out his stylus. Finally, his work done, he takes the tablet down to the archive.
For more than 3,700 years, the tablet languished in obscurity, until late-nineteenth-century collectors unearthed it from Sippar's ruins along the Euphrates River in what is now Iraq. Like similar tablets, it hinted at an ancient and mysterious Near Eastern currency, in the form of silver rings, that started circulating two millennia before the world's first coins were struck. By the time that tablet was inscribed, such rings may have been in use for a thousand years.
When did humans first arrive at the concept of money? What conditions spawned it? And how did it affect the ancient societies that created it? Until recently, researchers thought they had the answers. They believed money was born, as coins, along the coasts of the Mediterranean in the seventh or sixth century B.C., a product of the civilization that later gave the world the Parthenon, Plato, and Aristotle. But few see the matter so simply now. With evidence gleaned from such disparate sources as ancient temple paintings, clay tablets, and buried hoards of uncoined metals, researchers have revealed far more ancient money: silver scraps and bits of gold, massive rings and gleaming ingots.
In the process, they have pushed the origins of cash far beyond the sunny coasts of the Mediterranean, back to the world's oldest cities in Mesopotamia, the fertile plain created by the Tigris and Euphrates rivers. There, they suggest, wealthy citizens were flaunting money at least as early as 2500 B.C. and perhaps a few hundred years before that. "There's just no way to get around it," says Marvin Powell, a historian at Northern Illinois University in De Kalb. "Silver in Mesopotamia functions like our money today. It's a means of exchange. People use it for a storage of wealth, and they use it for defining value."
