Origins of “Leave no stone unturned” 

“Leave no stone unturned” is believed to have originated from a Greek legend. It refers to a general who buried his treasure after being defeated in battle. The treasure’s location was lost to time and when searchers went to seek it out, the Oracle of Delphi only gave them one piece of advice—look under every stone. The following excerpt comes from John Bartlett’s Familiar quotations: being an attempt to trace their source. When seeking out and writing about the source of “leave no stone unturned” he wrote that it: 

may be traced to a response of the Delphic Oracle, given to Polycrates, as the best means of finding a treasure buried by Xerxes’s general, Mardonius, on the field of Plataea. The Oracle replied Πάντα λίθον κίνει, Turn every stone.

In his book, Bartlett also speaks about a related story in which someone named Polycrates, or either Athens or Thebes sought out treasure buried by Mardonius, a general serving under Xerxes’s I. He was killed at the battle of Plataea and was rumored to have hidden his treasure under his tent. When Polycrates couldn’t find it, he consulted the Delphic Oracle and received the same reply. 

The modern form of the phrase, “leave no stone unturned,” came into public use in the mid-1500s. It can be found in “A manifest detection of the moste vyle and detestable vse of Diceplay, and other practises lyke the same, a Myrrour very necessary for all yonge Gentilmen & others sodenly enabled by worldly abūdace, to loke in. Newly set forth for their behoufe.” This early Modern English text includes the following line: 

that he wil refuse no labor nor leaue no stone vnturned, to pick vp a penny vnderneth.
