Origin: From throwing or slinging stones: a single stone that strikes two targets. The Académie française's first dictionary (1694) already lists it as a proverbial phrase, "to accomplish two things by a single means," and Diderot used it in his reviews of the Paris Salons. English keeps the arithmetic with different targets: "kill two birds with one stone."
