who said what's done is done in macbeth
What's done is done One of the first-recorded uses of this phrase was by the character Lady Macbeth in Act 3, Scene 2 of the tragedy play Macbeth (early 17th century), by the English playwright William Shakespeare, who said: "Things without all remedy Should be without regard: what's done, is done"[2] and "Give me your hand. What's done cannot be undone. – To bed, to bed, to bed!"[3]
The Scottish Play The Scottish Play and The Bard's Play are euphemisms for William Shakespeare's Macbeth. The first is a reference to the play's Scottish setting, the second a reference to Shakespeare's popular nickname. According to a theatrical superstition, called the Scottish curse, speaking the name Macbeth inside a theatre will cause disaster. A variation of the superstition also forbids quoting it within a theatre except as part of an actual rehearsal or performance of the play.
