The Poetics

Aristotle's 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 Aristotle's 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.

Aristotle (Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384-322 BC)[A] was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Lyceum, the Peripatetic school of philosophy, and the Aristotelian tradition. His writings cover many subjects. including physics, biology, zoology, metaphysics, logic, ethics, estheticspoetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in the city of Stagira in Northern Greece. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At seventeen or eighteen years of age he joined Plato's Academy in Athens and remained there until the age of thirty-seven (c. 347 BC).[4] Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored Alexander the Great beginning in 343 BC.[5] He established a library in the Lyceum which helped him to produce many of his hundreds of books on papyrus scrolls. Though Aristotle wrote many elegant treatises and dialogues for publication, only around a third of his original output has survived, none of it intended for publication.[6] Aristotle's views on physical science profoundly shaped medieval scholarship. Their influence extended from Late Antiquity and the Early Middle Ages into the Renaissance, and were not replaced systematically until the Enlightenment and theories such as classical mechanics. Some of Aristotle's zoological observations found in his biology, such as on the hectocotyl (reproductive) arm of the octopus, were disbelieved until the 19th century. His works contain the earliest known formal study of logic, studied by medieval scholars such as Peter Abelard and John Buridan. Aristotle's influence on logic also continued well into the 19th century.
