In this quote from Shakespeare's "Henry VII," the speaker emphasizes the idea that peace is enduring and will not be forgotten. Instead of fading away with time, the legacy of this peace will continue to inspire future generations. This notion suggests that great achievements and ideals continue to resonate, even after their original context has passed.
Furthermore, the imagery of the phoenix rising from its ashes symbolizes renewal and the cyclical nature of greatness. Just as the phoenix is reborn to shine again, so too will the values and accomplishments of the peace endure through new figures who will emerge, echoing the same admiration that was once felt. This reflects the timelessness of impactful moments in history.
