Which theme is reflected in this poem by Countee Cullen?

Her class lies late and snores

While poor black cherubs rise at seven
To do celestial chores.

You seal resign myself to you also i guess what you mean, i behold from the beach your crooked inviting fingers, i believe you refuse to go back without feeling of me, we must have a turn together, i undress, hurry me out of sight of the land, cushion me soft, rock me in billowy drowse, dash me with amorous wet, i can repay you. in this excerpt from "song of myself," which literary device does whitman use to address the sea? alliteration allusion apostrophe onomatopoeia
