Ars Poetica (Horace)

"Ars Poetica", or "The Art of Poetry" , sometimes referred to as the "Epistula ad Pisones", or "Epistle to the Pisos", is a poem written by Horace c. 19 BC, in which he advises poets on the art of writing poetry and drama. The Ars Poetica has "exercised a great influence in later ages on European literature, notably on French drama", and has inspired poets and authors since it was written. Although it has been well-known since the Middle Ages, it has been used in literary criticism since the Renaissance.
