Literature is full of ‘doubles’: characters who seem to move in tandem; or twins, whose familial bond and similarities are frequently employed for farcical effect. In Shakespeare’s ‘Twelfth Night’, for example, the sense of a clear identity becomes a tangled mess as Viola, in disguise as a boy called Cesario, falls in love with Duke Orsino, who loves Olivia; Viola has to deliver Orsino’s love letters to Olivia, who quickly falls in love with her as Cesario. Sebastian, Viola’s twin brother who she thought had died, enters on stage, and Olivia is soon smitten with him.
