Many idioms that have no obvious source are often referred to, for no good reason, as ‘old proverbs’. ‘Forewarned is forearmed’ has a genuine claim to be called such, as it dates from at least the end of the 16th century, and could be much earlier. The Latin saying ‘praemonitus, praemunitus’ loosely translates as ‘forewarned is forearmed’. There’s no evidence to show that the English proverb is merely a translation of the Latin though. The two sayings could easily have originated independently.
