Having thus distinguished the parts, let us now consider
the proper construction of the Fable or Plot, as that is at
once the first and the most important thing in Tragedy.
We have laid it down that a tragedy is an imitation of an
action that is complete in itself, as a whole of some magni-
tude;
for a whole may be of no magnitude to speak of.
Now a whole is that which has beginning, middle, and end.
A beginning is that which is not itself necessarily after
anything else, and which has naturally something else after
it;
an end is that which is naturally after something itself,
either as its necessary or usual consequent, and with nothing
else after it;
and a middle, that which is by nature after
one thing and has also another after it.
A well-constructed
Plot, therefore, cannot either begin or end at any point one
likes; beginning and end in it must be of the forms just
described.
Again: to be beautiful, a living creature, and
every whole made up of parts, must not only present a
certain order in its arrangement of parts, but also be of
a certain definite magnitude.
and order, and therefore impossible either (1) in a very
minute creature, since our perception becomes indistinct as
it approaches instantaneity; or (2) in a creature of vast
size-one, say, 1000 miles long-as in that case, instead of
the object being seen all at once, the unity and wholeness
of it is lost to the beholder.
Just in the same way, then,
as a beautiful whole made up of parts, or a beautiful living
creature, must be of some size, a size to be taken in by the
eye, so a story or Plot must be of some length, but of
a length to be taken in by the memory.
As for the limit
of its length, so far as that is relative to public performances
and spectators, it does not fall within the theory of poetry.
If they had to perform a hundred tragedies, they would
be timed by water-clocks, as they are said to have been
at one period.
The limit, however, set by the actual nature
of the thing is this: the longer the story, consistently with
its being comprehensible as a whole, the finer it is by
reason of its magnitude. As a rough general formula, 'a
length which allows of the hero passing by a series of
probable or necessary stages from misfortune to happiness,
or from happiness to misfortune,' may suffice as a limit for
the magnitude of the story.
