Orsino, the Duke and Count of Illyria, is a young man deeply and fashionably in love with Olivia. Her rejection of him leaves him in a deep and just as fashionable melancholy.
Rather than press his suit in person, he sends messengers to Olivia, and it is in fact quite possible that he has never actually met her, merely seen her at a distance. Now that he is in love, he no longer hunts, but he has a deep love of music that he frequently indulges in. He has a great affection for his newly-acquired page, Cesario, and gives him sage advice about love and women. He also uses Cesario as a messenger to Olivia. He was not always so weary, and has fought in sea-battles, including one against Antonio. Discovering that Cesario is loved by Olivia, he swears to drag them apart. Discovering that they are married, he turns his rage against Cesario in person. Discovering that Cesario is in fact a woman, who loves him dearly and is not married to Olivia, he decides to marry her instead.
