Nor for yours neither. You've ungently, Brutus,
Stole from my bed: and yesternight, at supper,
You suddenly arose, and walk'd about,
Musing and sighing, with your arms across,
And when I ask'd you what the matter was,
You stared upon me with ungentle looks;
I urged you further; then you scratch'd your head,
And too impatiently stamp'd with your foot;
Yet I insisted, yet you answer'd not,
But, with an angry wafture of your hand,
Gave sign for me to leave you: so I did;
Fearing to strengthen that impatience
Which seem'd too much enkindled, and withal
Hoping it was but an effect of humour,
Which sometime hath his hour with every man.
It will not let you eat, nor talk, nor sleep,
And could it work so much upon your shape
As it hath much prevail'd on your condition,
I should not know you, Brutus. Dear my lord,
Make me acquainted with your cause of grief.  

Is Brutus sick? and is it physical
To walk unbraced and suck up the humours
Of the dank morning? What, is Brutus sick,
And will he steal out of his wholesome bed,
To dare the vile contagion of the night
And tempt the rheumy and unpurged air
To add unto his sickness? No, my Brutus;
You have some sick offence within your mind,
Which, by the right and virtue of my place,
I ought to know of: and, upon my knees,
I charm you, by my once-commended beauty,
By all your vows of love and that great vow
Which did incorporate and make us one,
That you unfold to me, yourself, your half,
Why you are heavy, and what men to-night
Have had to resort to you: for here have been
Some six or seven, who did hide their faces
Even from darkness.  

Calpurnia. Caesar, I never stood on ceremonies,
Yet now they fright me. There is one within,
Besides the things that we have heard and seen,
Recounts most horrid sights seen by the watch.
A lioness hath whelped in the streets;
And graves have yawn'd, and yielded up their dead;
Fierce fiery warriors fought upon the clouds,
In ranks and squadrons and right form of war,
Which drizzled blood upon the Capitol;
The noise of battle hurtled in the air,
Horses did neigh, and dying men did groan,
And ghosts did shriek and squeal about the streets.
O Caesar! these things are beyond all use,
And I do fear them.
