All's Well That Ends Well

It's William Shakespeare's comedy, All's Well That Ends Well, of course. Written between 1603 and 1606, the play is based on a popular medieval story from Giovanni Boccaccio's Decameron (c. 1350-1353), a collection of 100 tales. Shakespeare probably read an English translation of Boccaccio's story in a book called The Palace of Pleasure (1595) by a guy named William Painter. Yeah, Shakespeare's a notorious plagiarizer alright, but borrowing from other writers was no big whoop back in the day.
