This alone cannot be imparted by another; it is the mark of genius, for
to make good metaphors implies an eye for resemblances.

Of the various kinds of words, the compound are best adapted to
Dithyrambs, rare words to heroic poetry, metaphors to iambic. In heroic
poetry, indeed, all these varieties are serviceable. But in iambic verse,
which reproduces, as far as may be, familiar speech, the most appropriate
words are those which are found even in prose. These are,--the current or
proper, the metaphorical, the ornamental.

Concerning Tragedy and imitation by means of action this may suffice.

As to that poetic imitation which is narrative in form and employs a
single metre, the plot manifestly ought, as in a tragedy, to be
constructed on dramatic principles. It should have for its subject a
single action, whole and complete, with a beginning, a middle, and an
end. It will thus resemble a living organism in all its unity, and
produce the pleasure proper to it. It will differ in structure from
historical compositions, which of necessity present not a single action,
but a single period, and all that happened within that period to one
person or to many, little connected together as the events may be. For as
the sea-fight at Salamis and the battle with the Carthaginians in Sicily
took place at the same time, but did not tend to any one result, so in
the sequence of events, one thing sometimes follows another, and yet no
single result is thereby produced. Such is the practice, we may say, of
most poets. Here again, then, as has been already observed, the
