Aristotle's Poetics (Greek: Περὶ ποιητικῆς , Latin: "De Poetica" ; c. 335 BCE) is the earliest surviving work of dramatic theory and first extant philosophical treatise to focus on literary theory in the West.
 This has been the traditional view for centuries.
 However, recent work is now challenging whether Aristotle focuses on literary theory per se (given that not one poem exists in the treatise) or whether he focuses instead on dramatic musical theory that only has language as one of the elements.
