I have it written on a small piece of paper stuck inside my pencil box. I can date the piece of paper to around 8 - 10 years ago, by my handwriting and the type of paper.
Given the timing, I’m assuming I either picked it up from an anthology, periodical or English language radio. Less likely: my clumsy translation from Russian (which I do speak) or Polish (which I don’t, but not knowing a language never stopped me yet.)
The only other possibility for the author would be Nabokov, but that seems very unlikely, given the ‘Polish’ in the first fragment.
No luck yet. One person does feel that it’s not likely to be Herbert because Herbert tends toward the very dense, and the fragments you have are simpler.
Sorry. I really wasn’t clear was I? I blame my lack of caffeine.
I think that the search for the poem is a dead end because the number and kind of the lines you have makes it unlikely we’ll stumble across someone who spontaneously remembers it. I’ll leave my queries up at my blog and on the board (email me if you would like a link to the board), but I’m not very hopeful at this point.
