As Archibald MacLeish's "Ars Poetica" is about poetry, students can theoretically connect any previous poems that they may have read with the text.
Students who have engaged with other works of Modernist poetry—such as T.S. Elliot's "The Love Song of Alfred J. Prufrock"—will also have the occasion to connect that poem to MacLeish's.
While reading Horace's "Ars poetica," students may also find it useful to recall and discuss Edith Hamilton's Greek Mythology.
