Literal Meaning.

From Shakespeare's Hamlet, 1603:

Claudius:

O, this is the poison of deep grief; it springs
All from her father's death. O Gertrude, Gertrude,
When sorrows come, they come not single spies
But in battalions. First, her father slain:
Next, your son gone; and he most violent author
Of his own just remove: the people muddied,
Thick and unwholesome in their thoughts and whispers,
For good Polonius' death; and we have done but greenly,
In hugger-mugger to inter him: poor Ophelia
Divided from herself and her fair judgment,
Without the which we are pictures, or mere beasts:
Last, and as much containing as all these,
Her brother is in secret come from France;
Feeds on his wonder, keeps himself in clouds,
And wants not buzzers to infect his ear
With pestilent speeches of his father's death;
Wherein necessity, of matter beggar'd,
Will nothing stick our person to arraign
In ear and ear. O my dear Gertrude, this,
Like to a murdering-piece, in many places
Gives me superfluous death.
