In evening light at still of day
Shadows are sweeping time away.
A man through his window sees it all,
The fading blue, the shadow fall.
At the upper edge of vision
Perfect pearl, divine precision.
As hidden jewel in tapestry,
Shines the orb through the trees.
Two thirds round, white edged, sharp and clean.
The last third blurs into the unseen.
Precise imperfection, edged and blurred
The Pearl Setter has not erred.
