actors. The parts of Tragedy which must
be treated as elements of the whole have been already mentioned. The
quantitative parts the separate parts into which it is divided--are here
enumerated.]

As the sequel to what has already been said, we must proceed to consider
what the poet should aim at, and what he should avoid, in constructing
his plots; and by what means the specific effect of Tragedy will be
produced.

A perfect tragedy should, as we have seen, be arranged not on the simple
but on the complex plan. It should, moreover, imitate actions which
excite pity and fear, this being the distinctive mark of tragic
imitation. It follows plainly, in the first place, that the change, of
fortune presented must not be the spectacle of a virtuous man brought
from prosperity to adversity: for this moves neither pity nor fear; it
merely shocks us. Nor, again, that of a bad man passing from adversity
to prosperity: for nothing can be more alien to the spirit of Tragedy;
it possesses no single tragic quality; it neither satisfies the moral
sense nor calls forth pity or fear. Nor, again, should the downfall of
the utter villain be exhibited. A plot of this kind would, doubtless,
satisfy the moral sense, but it would inspire neither pity nor fear; for
pity is aroused by unmerited misfortune, fear by the misfortune of a man
like ourselves. Such an event, therefore, will be neither pitiful
nor terrible. There remains, then, the character between these two
extremes,--that of a man who is not eminently good and just,-yet whose
misfortune is brought about not by vice or depravity, but by some error
or frailty. He must be one who is highly renowned and prosperous,--a
personage like Oedipus, Thyestes, or other illustrious men of such
families.

A well constructed plot should, therefore, be single in its issue,
rather than double as some maintain. The change of fortune should be not
from bad to good, but, reversely, from good to bad. It should come about
as the result not of vice, but of some great error or frailty, in a
character either such as we have described, or better rather than
worse. The practice of the stage bears out our view. At first the poets
recounted any legend that came in their way. Now, the best tragedies
are founded on the story of a few houses, on the fortunes of Alcmaeon,
Oedipus, Orestes, Meleager, Thyestes, Telephus, and those others who
have done or suffered something terrible. A tragedy, then,
