One key aspect of "Omen" is its meditation on fate and God, anticipating Hirsch's later explorations in this area. The poet uses flashbacks to the speaker's childhood and imagery of the powerful and overbearing night sky in order to suggest the presence of a higher power that works in predetermined natural cycles. Hirsch's specific implications about fate and God are not necessarily clear, and the poem is also important simply as an exploration of the emotion and fear related to impending death. Interpreting these emotions based on the realm of experience from his childhood, the speaker comes to feel extremely close to his friend at the same time as he is preparing to never see him again.
