 Studying extract from the prelude, here's how you can analyse this poem. In terms of structure, this poem is written as one stanza. It is a dramatic monologue. The poem opens with pathetic fallacy, which sets an almost romantic mood. The little boat that the narrator steals is personified as being a woman. This oxymoron shows that the narrator knows he's not supposed to be rowing this boat at night. The simile in line 11 and 12 shows the narrator is really arrogant. He thinks he can control nature. Also, this personification shows that he thinks nature is really passive. Yet a syndetone as well as repetition in line 22 shows that nature is turning against this person. Also, the alliteration as well as the simile here shows that nature has a dark side. It's turning against the man. Cezura here shows the narrator is horrified to realise that nature has a dark side. Semantic field of nature is used here to show he's terrified of its power.
