Katka

[RiverNotch]

I once loved a girl from Slovakia,
as rugged as the Tatras 
she swirled with Slavic snow. Not sure what it means for her to swirl the Tatra mountains with snow (and "Slavic" here is probably redundant).

She called me miláčik.
"Let's fly to Praha and twirl
 beneath gothic spires---" Changed the punctuation here to be a bit more polished.

So past the saints
Baroque on the bridge "saints Baroque" reads too manufactured. Probably better to swap them: "So past the Baroque / saints on the bridge / we bumbled around...."
we bumbled around 
cobbled Bohemian streets
until we found ourselves
next to the astronomical clock. Somehow this is a syllable too long. I'm tempted to suggest moving "clock" to the next line, or maybe going with the Czech "next to the Orloj."

"They blinded the maker," you told me
as skeleton death struck the hour---
"Cities make me tired, I'm going home." Repunctuated this stanza too.

In Slovak mountains "Slovak" feels redundant. Also maybe "up" instead of "in"?
we walked onto frozen lakes
and you taught me the words
for icicle and rainbow.

One day we found
a blind dog
in a snow storm 
walking in circles.
We took him back
to help him get warm
but he died and you said, imo this stanza's pretty much perfect, though it took a second reading to fully click.

"Life makes me tired, I'm going home." I'm moved to suggest cutting "I'm going home" this second time and maybe separating the first "I'm going home" into its own line, but that might change the meaning too much---Katka's home may be emphatically elsewhere. Then again, those mountains where the blind dog dies being Katka's home seems just that much more compelling, the nadir of the Eastern European vortex that she "swirls" in....
