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" Vincentio, the Duke of Vienna, makes it known that he intends to leave the city on a diplomatic mission. He leaves the government in the hands of a strict judge, Angelo. In the next scene, we find a group of soldiers on a Vienna street, expressing their hopes, in irreverent banter, that a war with Hungary is afoot, and that they will be able to take part. Mistress Overdone, the operator of a brothel frequented by these same soldiers, appears and tells them "there's one yonder arrested and carried to prison was worth five thousand of you all." She tells them that it is "Signor Claudio," and that "within these three days his head to be chopped off" as punishment for "getting Madam Julietta with child." Lucio, one of the soldiers who is later revealed to be Claudio's friend, is astonished at this news and rushes off. Then comes Pompey Bum, who works for Mistress Overdone as a pimp, but disguises his profession by describing himself as a mere 'tapster' (the equivalent of a modern bartender), avers to the imprisonment of Claudio and outrageously explains his crime as "Groping for trouts in a peculiar river." He then informs Mistress Overdone of Angelo's new proclamation, that "All houses [of prostitution] in the suburbs of Vienna must be plucked down." The brothels in the city "shall stand for seed: they had gone down too, but that a wise burgher put in for them." Mistress Overdone is distraught, as her business is in the suburbs. "What shall become of me?" she asks. Pompey replies with a characteristic mixture of bawdy humor and folk-wisdom, "fear you not: good counselors lack no clients: though you change your place, you need not change your trade... Courage! there will be pity taken on you: you that have worn your eyes almost out in the service, you will be considered." Pompey Bum, as he was portrayed by nineteenth-century actor John Liston Claudio is then led past Pompey and Overdone on his way to prison, and explains what has happened to him. Claudio married Juliet, but, as they have not completed all the strict legal technicalities, they were still considered to be unmarried when Juliet became pregnant. Angelo, as the interim ruler of the city, decides to enforce a law that fornication is punishable by death, so Claudio is sentenced to be executed. Claudio's friend, Lucio, visits Claudio's sister, Isabella, a novice nun, and asks her to intercede with Angelo on Claudio's behalf. Isabella obtains an audience with Angelo, and pleads for mercy for Claudio. Over the course of two scenes between Angelo and Isabella, it becomes clear that he lusts after her, and he eventually offers her a deal: Angelo will spare Claudio's life if Isabella yields him her virginity. Isabella refuses, but when she threatens to publicly expose his lechery, he tells her that no one will believe her because his reputation is too austere. She then visits her brother in prison and counsels him to prepare himself for death. Claudio desperately begs Isabella to save his life, but Isabella refuses. She believes that it would be wrong for her to sacrifice her own immortal soul (and that of Claudio, if his entreaties were to convince her to lose her virtue) to save Claudio's transient earthly life.
