Aristotles Poetics (Greek: Περὶ ποιητικῆς; Latin: De Poetica; 1] c. 335 BC 2]) is the earliest surviving work of dramatic theory and first extant philosophical treatise to focus on literary theory. 3] In it, Aristotle offers an account of what he calls poetry (a term that derives from a classical Greek term, ποιητής, that means poet; author; maker and in this context includes verse drama - comedy, tragedy, and the satyr play - as well as lyric poetry and epic poetry). They are similar in the fact that they are all imitations but different in the three ways that Aristotle describes: Differences in music rhythm, harmony, meter and melody. Difference of goodness in the characters. Difference in how the narrative is presented: telling a story or acting it out.In examining its first principles, Aristotle finds two: 1) imitation and 2) genres and other concepts by which that of truth is applied/revealed in the poesis. His analysis of tragedy constitutes the core of the discussion. 4] Although Aristotles Poetics is universally acknowledged in the Western critical tradition, almost every detail about his seminal work has aroused divergent opinions. 5] The work was lost to the Western world for a long time. It was available in the Middle Ages and early Renaissance only through a Latin translation of an Arabic version written by Averroes.
