Cyrus spares Croesus' life when he realizes he is an ordinary man. First Cyrus orders that Croesus burns to death on a pyre because he wants to prove that he has supernatural powers that would prevent him from burning. Then Cyrus changes his mind. However, his servants can't put out the flames, so Croesus prays to Apollo and a storm extinguishes the fire.
In the end, Cyrus is certain that Croesus is a good man and makes him his advisor.
In this poem, the author describes the "music" that the movement of the black girl brings to our ears. He talks about the way in which the girl's playing makes her braids move, and he describes this musicality by using words such as "symphony","crescendo", and "movement." These words are employed as imagery, and their effect is that they create an image in the mind of the reader. This image contributes to the meaning of the poem by portraying the vivacity and cheerfulness of the girl.
