The Duke and ruler of Illyria. At the beginning of the play Orsino is obsessed by his unrequited love for Olivia . However, in the final scene, when Orsino discovers that Cesario is in fact the woman, Viola—and that Olivia has already married Viola's twin brother, Sebastian—he quickly proposes to Viola. Because the language and gestures he uses to talk about love are so melodramatic, and because he switches from Olivia to Viola so quickly, Orsino seems more in love with the idea of love and his own role as a spurned lover, than to actually be in love. His constant self-indulgent complaints about his lovesickness also display his extreme self-centeredness. Critics have also noted that, in the final scene, he seems to be attracted to Cesario as Cesario—that is, to Viola in her male persona.
