ARISTOTLE'S POETICS

I

I propose to treat of Poetry in itself and of its various kinds, noting
the essential quality of each; to inquire into the structure of the plot
as requisite to a good poem; into the number and nature of the parts of
which a poem is composed; and similarly into whatever else falls within
the same inquiry. Following, then, the order of nature, let us begin with
the principles which come first.

Epic poetry and Tragedy, Comedy also and Dithyrambic: poetry, and the
music of the flute and of the lyre in most of their forms, are all in
their general conception modes of imitation. They differ, however, from
one: another in three respects,--the medium, the objects, the manner or
mode of imitation, being in each case distinct.

For as there are persons who, by conscious art or mere habit, imitate and
represent various objects through the medium of colour and form, or again
by the voice; so in the arts above mentioned, taken as a whole, the
imitation is produced by rhythm, language, or 'harmony,' either singly or
combined.

Thus in the music of the flute and of the lyre, 'harmony' and rhythm
alone are employed; also in other arts, such as that of the shepherd's
pipe, which are essentially similar to these. In dancing, rhythm alone is
used without 'harmony'; for even dancing imitates character, emotion, and
action, by rhythmical movement.

There is another art which imitates by means of language alone, and that
