Here's a reference to "Venus Velvet No. 2," where all is done in play in the final stanzas of their physical love.

This makes me think of the cancer cells that were previously unseen, but then made themselves known.

I'm not a math major by any means, but I do remember that there is a mathematical concept linked to the spiral, called the "fibonacci sequence." This reference reminds me of Archimedes and his math allusions.

These come from Egypt, not Sicily and I wonder if this gives a reference to the travels Archimedes take to find out how much sand there is? I could be digging way too deep though.

This line appears more than once, maybe to add to the repetition of counting sand over and over again

Mica gold is a gold imposter or a "Fool's Gold." Maybe references an overall feeling of false hope?

This is by far my favorite three lines in the poem. It seems to be the most striking lines, discussing the strength of their love that can surpass death, in a way. "it will be fit for verse," ives the idea that perhaps they have already died from it, as their love is "fit for verse" in this very poem.
