Twelfth Night is a romantic comedy, and romantic love is the play’s main focus. Despite the fact that the play offers a happy ending, in which the various lovers find one another and achieve wedded bliss, Shakespeare shows that love can cause pain. Many of the characters seem to view love as a kind of curse, a feeling that attacks its victims suddenly and disruptively. Various characters claim to suffer painfully from being in love, or, rather, from the pangs of unrequited love. At one point, Orsino depicts love dolefully as an “appetite” that he wants to satisfy and cannot (I.i.1–3); at another point, he calls his desires “fell and cruel hounds” (I.i.21). Olivia more bluntly describes love as a “plague” from which she suffers terribly (I.v.265). These metaphors contain an element of violence, further painting the love-struck as victims of some random force in the universe. Even the less melodramatic Viola sighs unhappily that “My state is desperate for my master’s love” (II.ii.35). This desperation has the potential to result in violence—as in Act V, scene i, when Orsino threatens to kill Cesario because he thinks that -Cesario has forsaken him to become Olivia’s lover.

Love is also exclusionary: some people achieve romantic happiness, while others do not. At the end of the play, as the happy lovers rejoice, both Malvolio and Antonio are prevented from having the objects of their desire. Malvolio, who has pursued Olivia, must ultimately face the realization that he is a fool, socially unworthy of his noble mistress. Antonio is in a more difficult situation, as social norms do not allow for the gratification of his apparently sexual attraction to Sebastian. Love, thus, cannot conquer all obstacles, and those whose desires go unfulfilled remain no less in love but feel the sting of its absence all the more severely.

Gender is one of the most obvious and much-discussed topics in the play. Twelfth Night is one of Shakespeare’s so-called transvestite comedies, in which a female character—in this case, Viola—disguises herself as a man. This situation creates a sexual mess: Viola falls in love with Orsino but cannot tell him, because he thinks she is a man, while Olivia, the object of Orsino’s affection, falls for Viola in her guise as Cesario. There is a clear homoerotic subtext here: Olivia is in love with a woman, even if she thinks he is a man, and Orsino often remarks on Cesario’s beauty, suggesting that he is attracted to Viola even before her male disguise is removed. This latent homoeroticism finds an explicit echo in the minor character of Antonio, who is clearly in love with his male friend, Sebastian. But Antonio’s desires cannot be satisfied, while Orsino and Olivia both find tidy heterosexual gratification once the sexual ambiguities and deceptions are straightened out.

Yet, even at the play’s close, Shakespeare leaves things somewhat murky, especially in the Orsino-Viola relationship. Orsino’s declaration of love to Viola suggests that he enjoys prolonging the pretense of Viola’s masculinity. Even after he knows that Viola is a woman, Orsino says to her, “Boy, thou hast said to me a thousand times / Thou never should’st love woman like to me” (V.i.260–261). Similarly, in his last lines, Orsino declares, “Cesario, come— / For so you shall be while you are a man; / But when in other habits you are seen, / Orsino’s mistress, and his fancy’s queen” (V.i.372–375). Even once everything is revealed, Orsino continues to address Viola by her male name. We can thus only wonder whether Orsino is truly in love with Viola, or if he is more enamoured of her male persona.

The problem of social ambition works itself out largely through the character of Malvolio, the steward, who seems to be a competent servant, if prudish and dour, but proves to be, in fact, a supreme egotist, with tremendous ambitions to rise out of his social class. Maria plays on these ambitions when she forges a letter from Olivia that makes Malvolio believe that Olivia is in love with him and wishes to marry him. Sir Toby and the others find this fantasy hysterically funny, of course—not only because of Malvolio’s unattractive personality but also because Malvolio is not of noble blood. In the class system of Shakespeare’s time, a noblewoman would generally not sully her reputation by marrying a man of lower social status.

Yet the atmosphere of the play may render Malvolio’s aspirations less unreasonable than they initially seem. The feast of Twelfth Night, from which the play takes its name, was a time when social hierarchies were turned upside down. That same spirit is alive in Illyria: indeed, Malvolio’s antagonist, Maria, is able to increase her social standing by marrying Sir Toby. But it seems that Maria’s success may be due to her willingness to accept and promote the anarchy that Sir Toby and the others embrace. This Twelfth Night spirit, then, seems to pass by Malvolio, who doesn’t wholeheartedly embrace the upending of order and decorum but rather wants to blur class lines for himself alone.

Twelfth Night features a great variety of messages sent from one character to another—sometimes as letters and other times in the form of tokens. Such messages are used both for purposes of communication and miscommunication—sometimes deliberate and sometimes accidental. Maria’s letter to Malvolio, which purports to be from Olivia, is a deliberate (and successful) attempt to trick the steward. Sir Andrew’s letter demanding a duel with Cesario, meanwhile, is meant seriously, but because it is so appallingly stupid, Sir Toby does not deliver it, rendering it extraneous. Malvolio’s missive, sent by way of Feste from the dark room in which he is imprisoned, ultimately works to undo the confusion caused by Maria’s forged letter and to free Malvolio from his imprisonment.

But letters are not the only kind of messages that characters employ to communicate with one another. Individuals can be employed in the place of written communication—Orsino repeatedly sends Cesario, for instance, to deliver messages to Olivia. Objects can function as messages between people as well: Olivia sends Malvolio after Cesario with a ring, to tell the page that she loves him, and follows the ring up with further gifts, which symbolize her romantic attachment. Messages can convey important information, but they also create the potential for miscommunication and confusion—especially with characters like Maria and Sir Toby manipulating the information.

No one is truly insane in Twelfth Night, yet a number of characters are accused of being mad, and a current of insanity or zaniness runs through the action of the play. After Sir Toby and Maria dupe Malvolio into believing that Olivia loves him, Malvolio behaves so bizarrely that he is assumed to be mad and is locked away in a dark room. Malvolio himself knows that he is sane, and he accuses everyone around him of being mad. Meanwhile, when Antonio encounters Viola (disguised as Cesario), he mistakes her for Sebastian, and his angry insistence that she recognize him leads people to assume that he is mad. All of these incidents feed into the general atmosphere of the play, in which normal life is thrown topsy-turvy, and everyone must confront a reality that is somehow fractured.

Many characters in Twelfth Night assume disguises, beginning with Viola, who puts on male attire and makes everyone else believe that she is a man. By dressing his protagonist in male garments, Shakespeare creates endless sexual confusion with the Olivia-Viola--Orsino love triangle. Other characters in disguise include Malvolio, who puts on crossed garters and yellow stockings in the hope of winning Olivia, and Feste, who dresses up as a priest—Sir Topas—when he speaks to Malvolio after the steward has been locked in a dark room. Feste puts on the disguise even though Malvolio will not be able to see him, since the room is so dark, suggesting that the importance of clothing is not just in the eye of the beholder. For Feste, the disguise completes his assumption of a new identity—in order to be Sir Topas, he must look like Sir Topas. Viola puts on new clothes and changes her gender, while Feste and Malvolio put on new garments either to impersonate a nobleman (Feste) or in the hopes of becoming a nobleman (Malvolio). Through these disguises, the play raises questions about what makes us who we are, compelling the audience to wonder if things like gender and class are set in stone, or if they can be altered with a change of clothing.

The instances of mistaken identity are related to the prevalence of disguises in the play, as Viola’s male clothing leads to her being mistaken for her brother, Sebastian, and vice versa. Sebastian is mistaken for Viola (or rather, Cesario) by Sir Toby and Sir Andrew, and then by Olivia, who promptly marries him. Meanwhile, Antonio mistakes Viola for Sebastian, and thinks that his friend has betrayed him when Viola claims to not know him. These cases of mistaken identity, common in Shakespeare’s comedies, create the tangled situation that can be resolved only when Viola and Sebastian appear together, helping everyone to understand what has happened.

When Olivia wants to let Cesario know that she loves him, she sends him a ring by way of Malvolio. Later, when she mistakes Sebastian for Cesario, she gives him a precious pearl. In each case, the jewel serves as a token of her love—a physical symbol of her romantic attachment to a man who is really a woman. The gifts are more than symbols, though. “Youth is bought more oft than begged or borrowed,” Olivia says at one point, suggesting that the jewels are intended almost as bribes—that she means to buy Cesario’s love if she cannot win it (III.iv.3).

When Sir Toby and Maria pretend that Malvolio is mad, they confine him in a pitch-black chamber. Darkness becomes a symbol of his supposed insanity, as they tell him that the room is filled with light and his inability to see is a sign of his madness. Malvolio reverses the symbolism. “I say this house is as dark as ignorance, though ignorance were as dark as hell; and I say there was never man thus abused” (IV.ii.40–42). In other words, the darkness—meaning madness—is not in the room with him, but outside, with Sir Toby and Feste and Maria, who have unjustly imprisoned him.

Clothes are powerful in Twelfth Night. They can symbolize changes in gender—Viola puts on male clothes to be taken for a male— as well as class distinctions. When Malvolio fantasizes about becoming a nobleman, he imagines the new clothes that he will have. When Feste impersonates Sir Topas, he puts on a nobleman’s garb, even though Malvolio, whom he is fooling, cannot see him, suggesting that clothes have a power that transcends their physical function.
