I happened on this translation by Clare Cavanagh and Michał Rusinek of a Miron Białoszewski poem in the NYRB :

It’s Easy to Lose Faith

A horse and cart went past.

I see. I believe in them.

They grow dark.

The horse and cart went past.

But the horse had a horse.

The cart had a cart.

They led their own selves

large from shadows

along the acacias.

And now it’s hard for me to believe

in the horse and cart.

Here’s the original Polish:

Jak łatwo stracić wiarę

Przeszedł koń i fura.

Widzę. Wierzę w nich.

Ściemnia się.

Przeszedł koń i fura.

Ale koń miał konia.

Fura miała furę.

Prowadzili te swoje

wielkie z cieni

po akacjach

I już mi trudno uwierzyć

w konia i furę.

I like the poem and the translation; what I’m wondering is if Prowadzili te swoje wielkie z cieni necessarily implies they were leading “their own selves” or simply unspecified large things of theirs. I do not know Polish, I just triangulate from other Slavic.…
