Viola

Viola is an aristocrat who washes up on Illyria’s shore and disguises herself as a man called ‘Cesario’ in order to become Orsino’s servant. He sends her to woo Olivia on his behalf, and her disguise prevents her from telling Orsino that she has fallen in love with him, or telling Olivia why she cannot love her back when the countess falls in love with ‘Cesario.’
