tall, and sound, and hardy

I am tall, and sound, and hardy,
Have no flaws within my body;
Three times in the months of summer,
In the warmest of the seasons,
Does the sun dwell in my tree-top,
On my trunk the moonlight glimmers,
In my branches sings the cuckoo,
In my top her nestlings slumber.

Kalevala, Rune XVI, translated by John Martin Crawford
