Classic Poem

My harvest is done, its promise is ended,
Weak and watery sets the sun,
Day and night in one mist are blended,
My harvest is done.

Long while running, how short when run,
Time to eternity has descended,
Timeless eternity has begun.

Was it the narrow way that I wended?
Snares and pits was it mine to shun?
The scythe has fallen, so long suspended,
My harvest is done.
