Short Answer 
The author expresses a desire to have been born a pagan for a different understanding of nature, appreciating its beauty beyond religious constraints. Additionally, he discusses the structure and significance of sonnets, highlighting the role of the volta as a pivotal emotional turning point.
Step 1: Understanding the Wish
The author expresses a profound *longing* to have been born a pagan. This desire stems from the belief that a pagan upbringing would have provided him with a distinct perspective on nature. By embracing nature without the constraints of organized religion, he feels he could appreciate its beauty and mystery more deeply.
Step 2: The Structure of Sonnets
The narrative also reflects the author’s admiration for the *iambic* form, which is often used in *sonnets*. A sonnet is a poetic composition consisting of 14 lines, traditionally originating from Italian poetry. There are various forms of sonnets, including those with:
- Eight lines that typically introduce a problem or theme.
- Six lines that usually provide a resolution or shift in perspective.
Step 3: The Turning Point in Sonnets
In the structure of a sonnet, the shift in direction, known as the volta or turning point, occurs after the eighth line. This *turn* is crucial as it transforms the emotional or thematic trajectory of the poem, allowing the reader to experience a *resolution* or new insight. This element contributes significantly to the depth and complexity of the sonnet’s overall message.
