Measure for Measure is a play by William Shakespeare, believed to have been written in 1603 or 1604. It was (and continues to be) classified as comedy, but its mood defies those expectations. Some critics have labelled it as one of Shakespeare's problem plays.
Originally published in the First Folio of 1623 (where it was first labelled as a comedy), the play's first recorded performance was in 1604. The play deals with the issues of mercy, justice, and truth and their relationship to pride and humility: "Some rise by sin, and some by virtue fall"
