Day the twelfth

Today the prompt is to write a triolet.

One day


This day was born in the silver grey of rain
And grew wise from the added soft of sun;
It danced to keening windsong over and again;
This day was born in the silver grey of rain
And battled man's insane tyranny of pain
And lived through all the hours 'til it was done;
This day was born in the silver grey of rain
And grew wise from the added soft of sun.
