A poem by Pimien Pancanka in Like Water, like Fire is simply titled
* * *, and it was labeled "Iran, 1944" at the end.
It includes the following lines:
The cranes fly beyond Kazbek and El'brus,
Heart contracts with its yearning and need.
Soon she will greet them, my Belarus,
In the warm green of the meads.
So, Mount Kazbek is on the border of Georgia and Russia, and El'brus is in Russia. So, I assume that the cranes are flying north from Iran through Georgia; indeed, that path would eventually lead to Belarus.
I'm slightly confused about one point, though: how could the author have seen them do that? Again, Kazbek is in Georgia, which is separated from Iran by Armenia and Azerbaijan.
Similarly, Belarus is separated from Georgia by Ukraine as well as parts of Bulgaria and Russia.
That being said, why did the author referred to this particular point?
