Desdemona left the garden, and Iago asked if it was really true that Cassio had known Desdemona before her marriage.
“Yes,” said Othello.
“Indeed,” said Iago, as though something that had mystified him was now very clear.
“Is he not honest?” demanded Othello, and Iago repeated the adjective inquiringly, as though he were afraid to say “No.”
“What do you mean?” insisted Othello.
To this Iago would only say the flat opposite of what he said to Cassio. He had told Cassio that reputation was humbug. To Othello he said, “Who steals my purse steals trash, but he who filches from me my good name ruins me.”
At this Othello almost leapt into the air, and Iago was so confident of his jealousy that he ventured to warn him against it. Yes, it was no other than Iago who called jealousy “the green-eyed monster which doth mock the meat it feeds on.”
Iago having given jealousy one blow, proceeded to feed it with the remark that Desdemona deceived her father when she eloped with Othello. “If she deceived him, why not you?” was his meaning.
Presently Desdemona re-entered to tell Othello that dinner was ready. She saw that he was ill at ease. He explained it by a pain in his forehead. Desdemona then produced a handkerchief, which Othello had given her. A prophetess, two hundred years old, had made this handkerchief from the silk of sacred silkworms, dyed it in a liquid prepared from the hearts of maidens, and embroidered it with strawberries. Gentle Desdemona thought of it simply as a cool, soft thing for a throbbing brow; she knew of no spell upon it that would work destruction for her who lost it. “Let me tie it round your head,” she said to Othello; “you will be well in an hour.” But Othello pettishly said it was too small, and let it fall. Desdemona and he then went indoors to dinner, and Emilia picked up the handkerchief which Iago had often asked her to steal.
She was looking at it when Iago came in. After a few words about it he snatched it from her, and bade her leave him.
