Viola's actions produce all of the play's momentum. She is a young woman of Messaline. In the beginning, Viola is found shipwrecked on the shores of Illyria and separated from her twin brother, not knowing whether he is alive or dead, the Sea Captain tells her that this place is ruled by the Duke Orsino, who is in love with Countess Olivia. Viola wants to serve her, but, finding this impossible, she has the Sea Captain dress her up like a eunuch, so she can serve the Duke instead.
Viola chooses the name Cesario and secures a position as a page working for the Duke. He then entrusts Cesario (Viola) to express his love for Olivia, without knowing that Viola had begun to fall in love with him. When Viola hears this she is heartbroken but listens reluctantly. Cesario continues to pass messages back and forth between the Duke and Olivia, but this eventually places her in somewhat of a quandary: she is forced by duty to do her best to plead Orsino's case to Olivia, but an internal conflict of interest arises when she falls in love with Orsino, and Olivia, believing her to be male, falls in love with her. Upon receiving a ring from Olivia's steward, Viola contemplates the love triangle her disguise has created, admitting only time can solve it.
When Sebastian, Viola's lost twin, arrives alive and well in Illyria with a pirate named Antonio, the chaos of mistaken identity ensues because of their remarkably similar looks, only made more similar due to Viola dressing up as a male. The absurdity of the identity crisis builds until Sebastian and Viola as Cesario meet for the first time, and eventually recognise one another. Olivia and Sebastian have already been secretly married, as she mistook him for Cesario, and Sebastian, ignorant of the foregoing love triangle, was simply entranced by a beautiful woman. Ultimately then, given what he has witnessed, Orsino admits that he will no longer pursue Olivia, agreeing to love her as his sister, and decides to take Viola as his wife once she quits her disguise.
Although Viola is the play's protagonist, her true name is not spoken by any character—including herself—until the final scene of the play (Act 5, scene 1).
Art and stage depictions
Circa 1771 Francis Wheatley used actress Elizabeth Younge as a model to paint Viola in Act III, Scene 4 after she and Sir Andrew have drawn swords (painting top-right).[1]
William Hamilton painted the confrontation between Olivia and Viola circa 1797: in Act V, Scene 1 Olivia believes Viola (dressed as Cesario) to be Sebastian (Viola's twin brother) who she has just married. After Viola denies any knowledge, incredulous Olivia asks the priest to confirm they were married just two hours prior.[2]
In the mid-19th century Frederick Richard Pickersgill painted a few scenes, including: in Act 1, Scene 4 after the character Viola is shipwrecked, when she cross-dresses as Cesario, enters the service of Duke Orsino as his page and falls in love with him; and in Act 3, Scene 1 when Olivia declares her love for Cesario (1859 painting).[4]
In the 20th century German actress Lucie Höflich played Viola in Was ihr wollt (Twelfth Night in German) at the Deutsches Theater in Berlin.[5]
