Concur so fearfully in one desire?
Roderigo, here thou seest two hostile stars,
That in the lapse of ages, only once,
As they sweep onwards in their orbed course,
Touch with a crash that shakes them to the centre,
Then rush apart forever and forever.

MARQUIS.
I feel a dire foreboding.

CARLOS.
So do I.
Like hell's grim furies, dreams of dreadful shape
Pursue me still. My better genius strives
With the fell projects of a dark despair.
My wildered subtle spirit crawls through maze
On maze of sophistries, until at length
It gains a yawning precipice's brink.
O Roderigo! should I e'er in him
Forget the father--ah! thy deathlike look
Tells me I'm understood--should I forget
The father--what were then the king to me?

MARQUIS (after a pause).
One thing, my Carlos, let me beg of you!
Whate'er may be your plans, do nothing,--nothing,--
Without your friend's advice. You promise this?

CARLOS.
All, all I promise that thy love can ask!
