Poetics

Aristotle's Poetics is the earliest surviving work of dramatic theory and first extant philosophical treatise to focus on literary theory.

The Poetics is primarily concerned with drama, and the analysis of tragedy constitutes the core of the discussion.

Although the text is universally acknowledged in the Western critical tradition, "almost every detail about [t]his seminal work has aroused divergent opinions".

Aristotle proposes to study poetry by analyzing its constitutive parts and then drawing general conclusions.

The portion of the Poetics that survives discusses mainly tragedy and epic poetry. ... He defines poetry as the mimetic, or imitative, use of language, rhythm, and harmony, separately or in combination.
