The phrase “Leave no stone unturned,” for example, is one that we hear in both casual talk and scholarly work today. But did you know that this expression came to us many centuries ago?
The phrase “leave no stone unturned” originated from a Greek legend that recounts the Oracle of Delphi telling Polycrates to “move every stone” in order to find a hidden treasure. This legend was translated into English in the 1500s using the phrasing “Leave no stone unturned.”
How fascinating that something said in ancient Greece—whether it came from the mouth of an oracle or a storyteller, would be part of the modern world’s lexicon. In this article, we are going to find out more about the history of this idiomatic expression and its meaning.

But how exactly did this expression come down to us, and how was it first used?
A Greek Legend As Recounted by Erasmus
The most well-known story of how the expression “Leave no stone unturned” came about goes back to the 1500s, during the time of Dutch philosopher Desiderius Erasmus. Erasmus, touted as “one of the greatest scholars of the Northern Renaissance,” translated stories from Greek and Roman sources.
One of the stories that Erasmus translated was a Greek legend dating back to 477 BC, with the Battle of Plataea during the Persian War as its backdrop. During this battle, King Xerxes of Persia invaded Greece in an attempt to make his European conquest complete. Xerxes had just come from several victories, including those at Thermopylae and Artemisium.
The prospect of a win, therefore, seemed to be only inevitable. But they could not be more wrong.
Unfortunately for the Persians, their troops in Europe, with Mardonius in command, were not strong enough to conquer Greece. In the Battle of Plataea, the Greeks overpowered the Persian troops, delivering a huge blow to Xerxes and his attempt at conquest.
The battle a complete loss to the Persians, Mardonius decided to hide his treasure by burying it in the ground near his tent and flee. Word came around that a great deal of treasure was hidden in Plataea and eventually reached the ears of Polycrates.
Wanting to get a hold of the treasure himself, he bought the land and ventured to search for the treasure, but he could not find it anywhere. Frustrated, Polycrates decided to consult the Oracle of Delphi.
According to legend, the Oracle told Polycrates to “move every stone” or to look under every stone. And voila—when Polycrates did exactly that, he saw the hidden gold.
It is said that the English translation of the Oracle’s words was “Leave no stone unturned” instead of “Move every stone,” and that is how we use it today.
There is a French idiom that is closely related to this expression, which is “Remuer ciel et terre,” which means “To move heaven and earth.” Like the phrase “Leave no stone unturned, it also is a common way of saying to do everything possible to achieve a goal.
There is also a much less exciting story about how the expression came down to us from history. That is the story of crab hunters overturning stones by the shores to look for crabs. If you think about it, it actually makes sense. Crabs do hide under rocks.
Although, if you ask me, the expression “Leave no stone unturned” sounds a bit too serious to simply be used when hunting for crustaceans at the beach—at least nowadays.
Usage by Euripides
Another instance where the expression was seen was in the Heraclidae, a tragic play by Euripides around 430 BC. In the play, Euripides uses the expression “Leave no rock unturned,” notably using the word “rock” instead of “stone.”
The meaning, however, is still the same as with “Leave no stone unturned,” which is to do all possible means to achieve an end.
Other ancient texts where the same expression can be found include the letters of Pliny the Young and Theocritus.
Whichever of these came first, it’s clear that the expression has been around for several centuries, and it has endured because it captures the sense of urgency involved when relating a very important undertaking—with, of course, the right amount of flair to make the expression last for generations.
