The work is also known for its discussion of the principle of decorum (the use of appropriate vocabulary and diction in each style of writing) (l.81–106), and for Horace's criticisms of purple prose "(purpureus pannus," l.15–16), a term coined by him to mean the use of flowery language. This principle is considered a core component of Horatian poetics as it principally aimed to achieve verisimilitude in artistic representation, guiding everything from the choice of genre to diction, dramatic characterization, meter, poetic invention, and the intended effect. Some cited that decorum enforces subordination such as of parts to whole, woman to man, desire to reason, and individual to state.
