As a high school student reading Twelfth Night, I find it one of the finest Shakespearean comedies. It is the story of two twins, Viola and Sebastian, who become shipwrecked and land on the island of Illyria, both thinking that the other is dead. It includes a classic example of mistaken identities, in which Viola disguises herself as a man (in order to work for Orsino) and is confused with Sebastian. Sebastian is mistaken for Cesario (Viola's fake identity) by Sir Toby and Sir Andrew, and then by Olivia, resulting in their marriage. Sebastian's friend Antonio mistakes Viola for Sebastian and is thrown in jail when Viola claims she doesn't know him. These cases of mistaken identity create a comical mess that is only resolved when Viola and Sebastian appear together, and everyone understands what has happened. The mistaken identities in this plot also create a complex love triangle between Orsino, Olivia and Viola. Viola finds herself falling for Orsino, who she woks disguised as Cesario. Orsino sends her to tell Olivia that he is in love with her. Viola does as her employer wishes, and Olivia falls in love with Cesario. While all this is going on, the reader is entertained with Sir Andrew's hopeless attempts to woo Olivia, and with the trick played on Olivia's head servant Malvolio by Sir Toby and Maria, Olivia's uncle and servant woman. While it can be confusing to keep track of characters true identities, it is definitely a worthwhile play. Having seen the play before actually reading it, I felt this comedy was just as entertaining and enjoyable to read as to see acted on stage.
