What do these key quotations mean?
O, when mine eyes did see Olivia first,
Methought she purged the air of pestilence!
Orsino
Act 1, scene 1
Pestilence means a type of disease, like the plague. In Shakespeare’s day it was believed that the plague spread through the air. Orsino’s language here is suggesting that Olivia’s beauty is so strong that it cleans the air of disease.
Come, boy, with me; my thoughts are ripe in mischief:
I’ll sacrifice the lamb that I do love,
To spite a raven’s heart within a dove.
Orsino
Act 5, scene 1
How does Orsino use language here to express his anger?
Orsino uses metaphors here to express his anger about the fact that Olivia loves Cesario. The lamb is Cesario (Viola) and Olivia is the dove with a raven’s heart. His language suggests he is threatening Cesario (Viola) with violence even though he considers Cesario (Viola) to be a friend as well as an employee.
One face, one voice, one habit, and two persons.
Orsino
Act 5, scene 1
Orsino is amazed when he sees Sebastian and his twin, Viola, together. Their identical appearance has caused much confusion to many characters at this point.
Listen to a scene
In Act 1, scene 1, Orsino opens the play with lines about music and love. He imagines that music is the food that feeds love and he wishes to have too much so that he becomes sick of love.
Listen to this audio clip of the scene:
Orsino: If music be the food of love, play on;
Give me excess of it, that surfeiting,
The appetite may sicken and so die.
That strain again, it had a dying fall;
O it came o’er my ear like the sweet sound
That breathes upon a bank of violets,
Stealing and giving odour. Enough; no more.
’Tis not so sweet now as it was before.
O spirit of love, how quick and fresh art thou,
That, notwithstanding thy capacity,
Receiveth as the sea. Nought enters there,
Of what validity and pitch soe’er,
But falls into abatement and low price
Even in a minute. So full of shapes is fancy,
That it alone is high fantastical.
