Prince of Parthia, IV.5
Thermusa: Save me – oh! – save me- ye eternal pow’rs –...
Arsaces: Your eyes seem fix’d upon some dreadful object, Horror and anguish cloath your whiten’d face. And your frame shakes with terror; I hear you speak as seeming earnest in discourse, yet hear no second voice.
Thermusa: What! Saw’st thou nothing?
Arsaces: Nothing.
Thermusa: Nor hear’d?—
Arsaces: Nor hear’d.
Compare that scene from The Prince of Parthia to this scene from William Shakespeare's Hamlet
Hamlet, III.4
Hamlet: Save me, and hover o’er me with your wings, you heavenly guards!...
Queen: Alas, how is’t with you, That you do bend your eye on vacancy, And with the incorporal air do hold discourse? Fort at your eyes your spirits wildly peep ... Whereon do you look? ... To whom do you speak this?
Hamlet: Do you see nothing there?
Queen: Nothing at all; yet all that is I see.
Hamlet: Nor did you nothing hear?
Queen: No, nothing but ourselves.
