COMPLEX

Investors were told that Rome wasn't built in a day, which is true, and also the sort of thing people say when they would rather not discuss the timeline in any more detail than that.


first recorded 12th c.

Despite naming the city, the proverb is medieval French rather than ancient Roman. Its earliest known form — "Rome ne fu[t] pas faite toute en un jour" ("Rome wasn't made all in one day") — appears in a collection of French verse, Li Proverbe au Vilain, written around 1190.

It reached English centuries later through translators and proverb-collectors: Richard Taverner used a version in his 1539 rendering of Erasmus's Adagia, and John Heywood printed it in his 1546 proverb book as "Rome was not bylt on a daie."

Even Queen Elizabeth I drew on it — in Latin, "Roma uno die non est condita" — during a 1563 address at Cambridge, making the point that her reign would need time to prove itself.
