The Kalevala, the ‘Metamorphoses – Ovid‘ of Finland has the most interesting genesis of them all:
So then the water-mother
the water-mother, air-lass
raised her knee out of the sea
her shoulder-blade from the wave
for the scaup a nesting-place
sweet land to live on.
that scaup, pretty bird
glides and hovers; it
spied the water-mother’s knee
on the bluish main;
thought it was grass hummock
a clump of fresh sward.
It flutters it glides
and it lands on the knee-cap.
There it builds its nest
laid its golden eggs:
six eggs were of gold
and iron egg the seventh.
