Its a critical appreciation essay. it’s ok just to do a running commentary, showing how the effect develops as the passage unfolds, with a paragraph of general introduction and conclusion to indicate what you feel are the main points. Think particularly about (i) what the passage as a whole seems to be trying to do; (ii) the particular techniques or devices that help to bring this about. Be fairly detailed; try to say something about most lines. You can use any translation, but make sure you indicate which. The most useful is Lattimore, who follows the same line-numbering as the Greek. A major online resource for Homer is the Homer Encyclopedia. Please include a bibliography that is Harvard referenced. Please also do not forget to talk about the themes in the poem and how they relate to the scene that the question is referring to.
