Wicked, how did you get power?
Tell how you become so naughty!
Damn you, bastard! Wretched iron!
I know your birth, you purblind fool,
I know well your source, you evil!
Once there walked three nature spirits,
three fiery daughters of the sky.
They milked their swelling breasts to earth,
They squeezed their milk into the fens.
From the first maid spurted black milk,
this turned into soft wrought iron.
White milk squirted the second maid,
this was the source of tempered steel.
The third maid spouted blood-red milk,
This gave birth to bog iron ore.
I know your birth, you purblind fool,
I know well your source, you evil!
Then you were not high and mighty,
not yet mighty, not yet haughty,
when you moaned in the white-hot furnace,
Whined under baeting hammers.
Saliva was brought from a viper,
venom from a black snake!
For iron wouldn’t harbor evil
Without saliva from snakes.
Shelter us, supreme Creator!
Keep us safe, God Almighty!
So the mankind would not perish,
mother’s child vanish without trace.
