Orsino, the Duke of Illyria, is sitting in his palace and enjoying himself by listening to music. He is in love and is in a whimsical, romantic mood, luxuriating in the various emotions which the music evokes. But he impulsively decides that he has heard enough, and after sending the musicians away, he expounds on the subject of love. Curio, one of his pages, asks his master if he wouldn't like to hunt; perhaps exercise will cure his master's soulful, philosophical moodiness. Orsino replies that he would like to hunt — but he would like to hunt the lovely Olivia, to whom he has sent another of his pages, Valentine, as an emissary. At that moment, Valentine enters. But he brings such bad news that he begs "not [to] be admitted": Olivia's brother has died, and she has vowed to mourn her brother's death for seven years. Surprisingly, the news does not dampen Orsino's spirit. He rhapsodizes on how a girl with such sensitivity can express her emotions; if she "hath a heart of that fine frame," he says, then she would be even more devoted and loyal to a lover.
