Shakespeare opens Twelfth Night by immediately establishing the play's central preoccupation with love and its many forms through Duke Orsino's famous soliloquy. Orsino embodies the conventions of the courtly lover — he is melancholy, eloquent, and completely absorbed in his own romantic suffering. His opening request for music reveals the artificial, performative nature of his passion; he doesn't simply want to hear music, he wants to overdose on it until he's sick of it, mirroring his approach to love itself.

The imagery Shakespeare employs reveals the contradictory nature of Orsino's desire. Love is simultaneously compared to food ("food of love"), the sea ("receiveth as the sea"), and hunting (the hart/heart pun). This multiplicity of metaphors suggests that Orsino doesn't truly understand what he feels — he's in love with the idea of being in love rather than with Olivia herself. The dramatic irony is palpable; the audience can see what Orsino cannot: that his passion is self-indulgent performance rather than genuine affection.

The introduction of Olivia through Valentine's report establishes a crucial parallel between the two nobles. Both Orsino and Olivia are trapped in excessive emotional states — his unrequited love, her extended mourning. Olivia's vow to grieve for seven years is as extreme and theatrical as Orsino's romantic posturing. Shakespeare uses these twin portraits of emotional excess to set up his comedy's exploration of how self-deception prevents genuine human connection.

The scene's classical allusion to Actaeon is particularly significant. In Ovid's myth, Actaeon accidentally sees Diana bathing and is transformed into a stag, then killed by his own hounds. Orsino's comparison of himself to Actaeon suggests he understands that his desires may ultimately destroy him, yet he seems to relish this romantic suffering. This establishes the play's interest in how people can become trapped by their own emotions and self-created narratives.
