Rules and Principles of a Poet Mentioned in ARS POETICA by Horace [Roman Critic].
Horace formulated his critical theory in ARS POETICA, known as the ART OF POETRY. He followed the ancient classical line. He advised the would be writers to follow Greek models rigorously and faithfully:
Be Homer's works your study and delight,
Read them by day, and meditate by night.

a) Poesis or the subject-matter
b) Poema or form, and,c) Poeta or the poet.
Poetry according to Horace, is a combination of fact and fiction, which both insructs and pleases the reader. Thus the function of poetry is "to instruct and to delight." The nature of poetry is "to charm the mind." The poetic composition must have unity of design. Horace remarks, "He who chooses his subject wisely will find that neither words nor lucid arrangement fail him" for "sound judgement is the basis and sourse of good writing."
