Roderigo. Here is her father's house: I'll call aloud.

Iago. Do, with like timorous accent and dire yell,
As when, by night and negligence, the fire
Is spied in populous cities.

One of his most favourite topics, on which he is rich indeed, and in
descanting on which his spleen serves him for a Muse, is the
disproportionate match between Desdemona and the Moor. This is a
clue to the character of the lady which he is by no means ready to
part with. It is brought forward in the first scene, and he recurs
to it, when in answer to his insinuations against Desdemona,
Roderigo says:

I cannot believe that in her--she's full of most blest
conditions.

Iago. Bless'd fig's end. The wine she drinks is made of
grapes. If she had been blest, she would never have married
the Moor.

And again with still more spirit and fatal effect afterwards, when
he turns this very suggestion arising in Othello's own breast to her
prejudice.

Othello. And yet how nature erring from itself--

Iago. Aye, there's the point;--as to be bold with you,
Not to affect many proposed matches
Of her own clime, complexion, and degree, &c.
