To thy false seeming! Blood, thou art blood.Apostrophe
Let’s write “good angel” on the devil’s horn.
’Tis not the devil’s crest.  Knock within.  How now, who’s there?

Teach her the way.  Servant exits.  O heavens,
Why does my blood thus muster to my heart,Synecdoche
Making both it unable for itself
And dispossessing all my other parts
Of necessary fitness?
So play the foolish throngs with one that swoons,
Come all to help him, and so stop the air
By which he should revive. AnalogyAnd even so
The general subject to a well-wished king
Quit their own part, and in obsequious fondness
Crowd to his presence, where their untaught love
Must needs appear offense.Analogy
