The sexual imagery Wilde uses throughout the Nightingale's death scene culminates in this passage, with the rose "trembl[ing] in ecstasy" as the song reaches its conclusion. Ultimately, this underscores the idea that the Nightingale's sacrifice is an act of love—in fact,
the act of love, since her death is a total sacrifice of selfhood, and therefore "selfless" in a very literal sense. Furthermore, the response of the world around her confirms the meaningfulness of her sacrifice, with even her "killer"—the Rose-tree—appreciating the beauty of her song and actions.
