In chapter 5, author talks about poetry and rhetorics. Poetry tends to create effect of persuasion and rhetoric tends to have effect of imitation. The fusion of both of them is important in literary work. Especially, he lists four important basic rhetorical figures: metaphor, metaphor, synecdoche and irony. In “The sea is history” by Derek Walcott, I found a type of art description that interests me. He states in the last section of poetry, “then came the synod of files, then came the secretarial heron, then came the bullfrog bellowing for a vote, fireflies with bright ideas and bats like jetting ambassadors and the mantis, like khaki police, and the furred caterpillars of judges examining each case closely.” I am not quite sure about it but I do think the method he used is metaphor. I believe he compares some of the most important positions in the country to tiny creatures that implying no matter how small the country is or how lowly the people living in it are, as long as the country can independently develop and free write its own real history. That will be the historic moment and event. The history is meaningful.
