Kill Two Birds With One Stone

First documented in English in 1656, in philosopher Thomas Hobbes's Questions Concerning Liberty, Necessity, and Chance, where he writes of satisfying "two arguments with one answer." Similar ideas may be considerably older; some etymologists point to equivalent Latin expressions predating Hobbes, and others connect it to the Greek myth of Daedalus supposedly killing two birds with one stone to gather feathers for his and Icarus's wings, though that mythological link has never been documented as the phrase's actual source rather than a coincidental parallel.
