On that basis, the earliest burials in the Forum would be around 1000 BCE, the huts on the Palatine around 750–700 BCE (excitingly close to 753 BCE, as many have observed). But even these dates are far from certain. Recent scientific methods – including ‘radiocarbon dating’, which calculates the age of any organic material by measuring the residual amount of its radioactive carbon isotope – have suggested that they are all too ‘young’, by as much as a hundred years.
