Kalevala's Day

and the day of Finnish culture

Kalevala is the national epic of Finland.
Here's an  example of it's poetry in English

Väinämöinen, old and steadfast,
Answered in the words which follow:
"Yet a harp might be constructed
Even of the bones of fishes,
If there were a skilful workman,
Who could from the bones construct it."
As no craftsman there was present,
And there was no skilful workman
Who could make a harp of fishbones,
Väinämöinen, old and steadfast,
Then began the harp to fashion,
And himself the work accomplished.
