1.1.19-26
Forsooth - masterly as he
Iago is at his most entertaining when attacking Cassio's character. Shakespeare gives him long words at the end of lines for Iago to roll around his tongue and spit out with sarcastic bile. A great arithmetician? Hardly a soldier at all. Iago riles Roderigo by characterising Cassio as a lightweight with no field experience and already married to boot. But the speech says much more than this. Every description is meant as an insult. Even if it does not look like an insult on the page, Iago makes it an insult to be a Florentine, to have a fair wife, to be bookish or even robed. With each one, Iago implicitly draws a contrast with himself, the wronged party. He is a solder, he has seen battle, he is a man of action and passion, not books and easy wives.
