What is appreciation of ancient poetry? (translation? Emotion? Or the understanding of words? )

More is translation, so that you can understand what happened at that time, when and where. Then there is the grasp of emotion, what kind of mood the poet is, whether to talk about the present with the past or to express his feelings with things. Of course, there are also explanations of special words, such as interchangeable words. How to understand them, it is difficult to achieve the poet's original artistic conception, so ancient poetry still lies in returning to ontology.
