In the Kalevala, the Finnish national epic, there is a myth of the world being created from the fragments of an egg laid by a goldeneye on the knee of Ilmatar, goddess of the air:

One egg's lower half transformed And became the earth below,

And its upper half transmuted And became the sky above;

From the yolk the sun was made,

Light of day to shine upon us;

From the white the moon was formed,

Light of night to gleam above us;

All the colored brighter bits

Rose to be the stars of heaven

And the darker crumbs changed into

Clouds and cloudlets in the sky.
