"You are aware, I suppose, that all mythology and poetry is a narration of events, either past, present, or to come? / Certainly, he replied. / And narration may be either simple narration, or imitation, or a union of the two? / [...] / And this assimilation of himself to another, either by the use of voice or gesture, is the imitation of the person whose character he assumes? / Of course. / Then in this case the narrative of the poet may be said to proceed by way of imitation? / Very true. / Or, if the poet everywhere appears and never conceals himself, then again the imitation is dropped, and his poetry becomes simple narration."
Plato, Republic, Book III
Michael Davis, a translator and commentator of Aristotle writes:
“ At first glance, mimesis seems to be a stylizing of reality in which the ordinary features of our world are brought into focus by a certain exaggeration, the relationship of the imitation to the object it imitates being something like the relationship of dancing to walking. Imitation always involves selecting something from the continuum of experience, thus giving boundaries to what really has no beginning or end. Mimêsis involves a framing of reality that announces that what is contained within the frame is not simply real. Thus the more "real" the imitation the more fraudulent it becomes."
