In a solitude of the sea Deep from human vanity, And the Pride of Life that planned her, stilly couches she.
Why it works
Hardy constructs 'The Convergence of the Twain' using eleven tercets, but each stanza functions as an AAA sestet condensed into three lines arranged in a long-short-long pattern. The third line is almost twice the length of the first two. This structure generates a lurching, wave-like rhythm that mirrors the poem's theme — the sinking of the Titanic — through its form. The extended final line of each stanza hits with the heaviness of an object sinking into deep water.
