Dickinson uses metaphor and imagery to heighten the emotional intensity of the moment just before death. The phrase “The Eyes around had wrung them dry –” suggests that the people witnessing the death have cried so much they have no tears left. It's a metaphor for emotional exhaustion and grief. The next lines “Breaths were gathering firm / For that last Onset” build tension, as if everyone is holding their breath in anticipation of death's final moment. The phrase “when the King / Be witnessed – in the Room –” is especially powerful. The “King” could be a metaphor for death, but it might also refer to God or a divine presence entering the space. Dickinson keeps it ambiguous, which adds to the mystery and emotional weight of the scene. She shows how people expect something profound or sacred at the moment of death yet, as we later learn in the poem, it’s interrupted by something as mundane as a fly.
