A Today programme presenter used the term imperium (cf. ‘emperor’) with reference to Donald Trump’s desire to annex Greenland. To a Roman, it meant the authority to give orders that must be obeyed, no matter what. Anyone invested with that power by the Roman state was accompanied by lictors, attendants carrying the fasces, an axe bound inside a collection of wooden rods, suggesting what might happen to someone who refused the order.
