Quote 13
IAGO
Now will I question Cassio of Bianca,
A huswife that by selling her desires
Buys herself bread and clothes. It is a creature
That dotes on Cassio—as 'tis the strumpet's plague
To beguile many and be beguiled by one.
He, when he hears of her, cannot restrain
From the excess of laughter. Here he comes: (4.1.110-116)
Here, Iago tells the audience that he'll trick Othello into believing that Cassio is bragging about an affair with Desdemona when, in reality, Cassio will be bragging about his relationship with Bianca, a courtesan.
Iago notes that Bianca's a "huswife" (or, hussy) who makes a living by forging relationships with men like Cassio. Iago makes some pretty obnoxious assumptions about Bianca. According to Iago, all "strumpets" deceive lots of men but usually end up being deceived (and heartbroken) by the one man they fall in love with. As evidence, Iago refers to the fact that Bianca is in love with Cassio, who doesn't love her back. Instead, Cassio finds her to be "laugh[able]" and makes fun of her when talking with his male friends. Our point? Although Iago accuses courtesans like Bianca of "beguile[ing]" men, this passage seems emblematic of the way the men in the play think nothing of using women. Also, Iago's the one doing all the "beguile[ing]" here, isn't he? It seems like Shakespeare's pretty sympathetic toward Bianca and the other women in the play.
Quote 14
IAGO
Even now, now, very now, an old black ram
Is tupping your white ewe. Arise, arise!
Awake the snorting citizens with the bell,
Or else the devil will make a grandsire of you.
[…]
you'll
have your daughter covered with a Barbary horse,
you'll have your nephews neigh to you, (1.1.97-100; 124-126)
In order to manipulate Brabantio's fears of miscegenation, Iago uses animal metaphors to suggest that Desdemona is being defiled by Othello. Check out "Race" for more on this.
Quote 15
IAGO
Faith, he tonight hath boarded a land carrack.
If it prove lawful prize, he's made for ever.
CASSIO
I do not understand.
IAGO
He's married. (1.2.60-63)
Iago describes marriage as the violent takeover of an enemy's prize ship. This brings us back to the theory that love is a war in Othello, and Iago is trying to play maestro – or more likely, general.
