In "The Penelopiad," Margaret Atwood explores themes of knowledge and mortality through the voice of Penelope, who reflects on her life after death. The quote "Now that I am dead, I know everything" emphasizes a profound realization that comes with the end of life, suggesting that death brings clarity and understanding of past events and choices.

Penelope's narrative invites readers to reconsider her story and role in the myth of Odysseus from a new perspective. By expressing this newfound knowledge, Atwood challenges traditional narratives, allowing Penelope to regain agency and share her insights, thus highlighting the complexity of truth and memory in storytelling.
