Long before cryptocurrencies, mobile payments and investments in the stock market, the economy of an area was based on exchanging a surplus good for another that was needed. Until the advent of coins and bills, bartering was the only known form of trade. A new study suggests that the germ of what we now know as the European economic system appeared at the end of the Bronze Age , thanks to the popularization of a measurement system and countless bronze fragments that functioned as currency.

The study, published in the Journal of Archaeological Science, details that measurement tools began to be used in southern Italy between 2300 and 1700 BC. These tools quickly spread throughout Europe and between 1200 and 800 BC they were already in use throughout the continent. Giancarlo Lago and Nicola Lalongo, the authors of the study, describe these utensils as follows: .

Different researchers have found numerous bronze and metal deposits from this time throughout Europe, the meaning of which has not been unraveled. The locations of these clusters are distributed indistinctly in numerous environments. Nor do they follow a religious or ritual pattern, since, despite finding fragments of swords or axes, all the parts of the same object are never found. The analysis of more than 3,000 pieces from 150 deposits found in Italy and northeastern Germany revealed that these follow a very close proportion to the stone weights used in the balances. "The weight of the fragments is always a multiple of the same unit of measurement," the researchers acknowledge. The weights vary between 8 and 10 grams, as does the shekel, the unit of measurement used in Mesopotamia and that always had an equivalent in silver.

"We always think that the origin of the currency had to be gold," says the professor from the Autonomous University of Barcelona, "but it is the least appropriate material because it is too limited in nature." The only mineral abundant enough to establish itself as a bargaining chip was silver, although most of it was found in the Middle East. Europe, for its part, was rich in copper mines. Risch does not rule out that at some point other material was used, although he believes that it is impossible to know today: "There could be another type of currency, such as fabrics or grain, but archaeologically we are not able to recognize it as such."

, considers Risch. Researchers believe that the existence of money in Prehistory may represent a full stop in our concept of the modern world. "If we admit that Western civilizations were not responsible for the invention of money, perhaps we can begin to banish the prejudices that support our supposed superiority," they say.
