The poem seems to be divided into two parts: lines 1 through 5 deal more in the empirical realm (from emotional pain to political defiance and out rage), while lines 6 through 12 veer off into the ethereal- and apocalyptic- world of ancient Troy and its Helen.
WHY should I blame her that she filled my days / With misery describes the pain of Yeats’ unrequited love. … that she would of late / Have taught to ignorant men most violent ways refers to Irish nationalists drawn to both her beauty and her nationalistic tendencies.
