*Vienna. Great Austrian city ruled by Duke Vincentio. As the duke himself realizes, Vienna is a moral morass, and bawdry and licentiousness of all sorts are rampant. The duke accepts responsibility for having been lax in enforcing the law. Corruption seethes throughout society from the nobility down to the base characters who are engaged less in a comic subplot than in a series of vulgar exemplifications of the pervasive moral decay. Concerned by the city’s deterioration, the duke devises a scheme to revive civic authority: Pretending to go to Poland, he puts the administration of the city in the charge of his trusted, and presumably virtuous, deputy, Angelo, and remains in Vienna disguised as a friar. While staying in a friary, he spies on Angelo. The friary, which should ordinarily be a place of quiet contemplation and prayer, thus becomes a den of intrigue.
Shakespeare’s Vienna is no joyous café society or waltz-and-chandelier ballroom for the aristocracy. Rife with pimps, prostitutes, lechers, violated virgins, and murderers, it is not ready to be overrun by the wave of puritanism set in motion by Angelo. Scenes set on a street provide a microcosm of Viennese society, especially its smart men-about-town, such as Lucio; low-life figures such as Pompey the bawdy clown, and the syphilitic Mistress Overdone. Even Angelo proves to be corrupt, and in the privacy of his own abode, he reveals his hypocritical dissembling and hidden lust.
