Bakowski

And a new book out too. Here’s a short sample:

Your journey will be long,
dangers certain.
From clouds snakes will fall.
These can be killed only
by those amongst you
who have eaten wolf.

Don’t drink from pond or stream
in which black reeds grow.
One mouthful will turn you to stone.
Sleep with an eagle feather
clasped in your fist.
This keeps away lightning.

(from “Instructions to horsemen, Krakow, Poland, 1241“)
