"It was the calm and silent night! Seven hundred years and fifty-three Had Rome been growing up to might, And now was queen of land and sea. No sound was heard of clashing wars, Peace brooded o'er the hushed domain; Apollo, Pallas, Jove, and Mars Held undisturbed their ancient reign In the solemn midnight, Centuries ago."
