alexander-yakushev / "Stonebreakers" by Ivan Franko
Last active October 5, 2022 04:27
Amateur translation from Ukrainian to English of the poem "Каменярі" ("Kamenyari") written by Іван Франко (Ivan Franko) in 1878.
I had a dream. Like there is ahead
And endless, empty and the wildest plane.
And I stand there, held by iron chain,
Under the tall rock made from finest granite
And next to me are thousands just like me.
The face of everyone is marked by woe and sorrow,
And eyes of everyone contain fervor of love.
And hands of everyone are chained with snakes of iron,
And every shoulder's bent low to the ground,
