John, thank-you for replying - it's good to know your thoughts on this, and shows me where I'm not communicating.
I do want to show that artists/poets/humans generally appropriate the moon - that ideas of the moon are often abstractions - and a kind of nonsense (how can anyone know what the moon tastes like?!)
I also want the poem to look at how, ultimately, the moon, as a physical thing, most often serves as a backdrop to human drama (in this case, the falling/suicide).
Maybe I need to return to a longer version, and I've trimmed this down too much. Either way, it's useful to have a perspective that shows where and how this doesn't work.
