Aristotle’s Poetics from the 4th century B.C. aims to give a short study of storytelling. It discusses things like unity of plot, reversal of situation, and character in the context of Greek tragedy, comedy and epic poetry. But it still applies today. It is especially popular with screenwriters as seen in many script gurus’ how-to books.
Posterior Analytics is the fourth of Aristotle's six texts on logic which are collectively known as the Organon ("Instrument"). Posterior Analytics deals with demonstration, definition, and scientific knowledge. Demonstration is distinguished as a syllogism productive of scientific knowledge, while Definition is marked as the statement of a thing's nature, a statement of the meaning of the name, or of an equivalent nominal formula.
