What is the meaning?

The poem "The Black Finger"to the lower right is a poem I am analyzing in my Harlem Renaissance class. A few of my classmates didn't like it because they couldn't understand it. Do you? What do you think it means?

She walks in Beauty

"She Walks in Beauty" by Lord Byron is a poem I read two semester's ago. I like the poem because of its romantic vibe and it's beautifully phrased. I thought I'd share the poem with everyone, you can also see a discussion of why the author wrote the poem by clicking on the link above.
