Read the passage from act 1, scene 3 of The Tragedy of Macbeth.Macbeth. Stay, you imperfect speakers, tell me more:By Sinel’s death I know I am Thane of Glamis; But how of Cawdor? the Thane of Cawdor lives,A prosperous gentleman; and to be kingStands not within the prospect of beliefNo more than to be Cawdor. Say, from whenceYou owe this strange intelligence? or why Upon this blasted heath you stop our wayWith such prophetic greeting? Speak, I charge you. [Witches vanish.] Banquo. The earth hath bubbles, as the water has,And these are of them. Whither are they vanish’d? Macbeth. Into the air, and what seem’d corporal meltedAs breath into the wind. Would they had stay’d! Banquo. Were such things here as we do speak about?Or have we eaten on the insane rootThat takes the reason prisoner?
