In order to specifically answer this question, I will explain how metaphorical language is applied by twentieth-century Caribbean poet Derek Walcott. In his acclaimed work Omeros, an epic poem, Walcott uses interpretive paradigms and metaphors by loosely connecting his home of St. Lucia to Troy, the setting of Homer’s Iliad. The use of metaphors in Walcott’s work is a vehicle for suffering, as the beauty of St. Lucia was destroyed by colonization and commodification. This erosion of nature and civilization is related to the invasion of mass tourism on the island of St. Lucia, which allegorically strips the region of its ancestral identity and culture.
This process of subverting European works by integrating them into new literary texts for post-colonial critique is called “canonical counter-discourse” by postcolonial theorist Helen Tiffin. Through this process and the emphasis on metaphoric power, we can understand and analyze the broader, historical concepts that are situated in Caribbean poetic works of this period. This symbolic approach to poetic writing and narrative form is rooted in the author’s personal experiences and interpretations. If we accept these philosophical parameters as the reader, we can connect to the poet’s metaphorical, inner world of language and how it relates to the story's subject matter.
