The basic premise of "Ars Poetica" is that a poem should fascinate the reader in the same way that a masterful painting or sculpture does—that is, it should be so astounding in the complexity and beauty of its imagery that it does not need to explain itself or give an evident message. It should be enough that the reader experiences it vividly and knows immediately what it is about. Poetry is meant to be read, not just heard. The poet who can make us see as well as hear will hold our attention for much longer than one who relies only on language to tell his story. Imagery is the key tool used by poets to achieve this effect. Images are powerful because they can evoke feelings in readers that words alone cannot. For example, when reading about the death of Julius Caesar, we feel sorrow for him even though we never meet him face-to-face. This is because his image has been engraved into our memories through poetry! In "Ars Poetica," Ovid tells us that the aim of poetry is to move us to love or hate, rejoice or weep. It is this range of emotion that makes poems such effective communication tools. When someone writes a poem about something that has affected them deeply, we know how they feel because it shows in their work. Ovid also states that poetry should be simple yet sublime.
