That Handkerchief did an Egyptian to my mother give. She was a charmer and could almost read the thoughts of people. She told her, while she kept it, Twould make her amiable and subdue my father entirely to her love; but if she lost it or made a gift of it, my father’s eye should hold her loathed, and his spirits should hunt after new fancies. Act 3.4 (56-63)
The handkerchief is brought up numerous times in the play, and is symbolic for the marriage between Othello and Desdemona. The interest I have in this quote is that Shakespeare is giving us a whole symbolic history for the handkerchief making its importance even more valuable in the play. The history also brings the idea that the handkerchief also represents love and fidelity.
