Can we then, on the other hand, following the precedent of _King Lear_,
and remembering the probable chronological juxtaposition of the two
plays, regard Iago as the leading figure from the point of view of
construction? This might at first seem the right view; for it is the
case that _Othello_ resembles _King Lear_ in having a hero more acted
upon than acting, or rather a hero driven to act by being acted upon.
But then, if Iago is taken as the leading figure, the usual mode of
construction is plainly abandoned, for there will nowhere be a crisis
followed by a descending movement. Iago's cause advances, at first
slowly and quietly, then rapidly, but it does nothing but advance until
the catastrophe swallows his dupe and him together. And this way of
regarding the action does positive violence, I think, to our natural
impressions of the earlier part of the play.

I think, therefore, that the usual scheme is so far followed that the
drama represents first the rise of the hero, and then his fall. But,
however this question may be decided, one striking peculiarity remains,
and is the cause of the unique effect of _Othello_. In the first half of
the play the main conflict is merely incubating; then it bursts into
life, and goes storming, without intermission or change of direction, to
its close. Now, in this peculiarity _Othello_ is quite unlike the other
tragedies; and in the consequent effect, which is that the second half
of the drama is immeasurably more exciting than the first, it is
approached only by _Antony and Cleopatra_. I shall therefore reserve it
for separate consideration, though in proceeding to speak further of
Shakespeare's treatment of the tragic conflict I shall have to mention
some devices which are used in _Othello_ as well as in the other
tragedies.
