"Immanent" is not a misspelling. I thought it was a misspelling.

"The Convergence of the Twain"--that's the point where two things meet! Thanks, Trevor!

Anyway, the things meeting are almost indisputably the Titanic and the glacier that drowned it. This becomes more evident when one remembers to read the subtitles: "Lines on the loss of the 'Titanic.'" The "vaingloriousness" of the affair is evidenced in the mentioning of such items as mirrors and jewels which have been ravaged by "salamandrine fires."

Also, the "Immanent Will" seems to me like a description of fate. Is it personification if it's capitalized like that? Probably it is not. Similarly, I believe "Spinner of the Years" to be a metaphor-type-thing for God.

The format of this poem was intriguing as well.... Why eleven stanzas, Mr. Hardy?
