A group of scientists studied the inclusion of gas within the Arctic glaciers.
Having studied the glaciers of the Arctic, scientists have been able to make unexpected discoveries that shed light on the history of Ancient Rome.
When we talk about Ancient Rome, the last place to which you turn an inquisitive historian is Arctic ice. However, as it turned out, the glaciers represent a real “time capsule” of natural origin. As the Arctic sea ice freezes, but very rarely melts, its content is preserved for thousands of years.
In fact, this ha represents fragments of the atmosphere of the past, so the researchers were able to get an idea about its composition and, in particular, on the concentration of carbon dioxide in the air. But the work is not limited to: scientists looked for traces of lead. The fact that even though the lead and was a highly valued metal in Ancient Rome, a significant part of it fell into the atmosphere during processing of other, far more valuable metal — silver.
Thus, the more lead in the atmosphere — the greater was the production of silver in this or that period of Roman history. According to researchers, increasing the amount of precious metal in circulation is evidence of the strengthening economy. This is very valuable information, because only a small part of the financial statements of those years have reached our days. As a result, scientists confirmed the hypothesis previously advanced by historians: in the period from 27 to 180 ad, Rome was at the peak of its economic development, and the levels of decline of lead in the samples coincided with the periods of epidemics and invasions, during which the economy was expected to decline.
