'DECLINE AND FALL OF ROMAN EMPIRE’?
In Roman times, the metal lead was common.
It was called plumbum and was used for making containers, various cooking implements and water pipes.
They also store their wine in lead vats and even added it to some wines to improve their flavour!
Lead is poisonous and perhaps, one of the reasons for the ‘decline and downfall’ of the Roman Empire was lead poisoning!
