Chaos is come again.

Iago. My noble lord,—

Othello.     What dost thou say, Iago?

Iago. Did Michael Cassio, when you woo’d my lady,

Know of your love?

Othello. He did, from first to last. Why dost thou ask?

Iago. But for a satisfaction of my thought;

No further harm.

Othello.    Why of thy thought, Iago?

Iago. I did not think he had been acquainted with her.
