Although an author's origin can have some influence in his writing, it is unlikely that this will help us find the purpose of a specific work. Instead, we can look at the context and the details of the text. Studying what the historical and cultural context of an author's work was like can allow us to discover what the important values and events of his time were. In turn, this might illuminate some of the concerns that an author might have had while writing. Examining the details of the text can also allow us to discover the author's purpose by providing clues in devices such as metaphors and symbols.
