Ay Me!

Silent, with hands crost meekly on his breast,
Long time, with keen and meditative eye,
Stood the old painter of Siena by
A canvas, whose sign manual him confest.
  
His head droopt low, his eye ceased from its quest,
As tears filled full the fountains long since dry;
And from his lips there broke the haunting cry:
"May God forgive me - I did not my best!"
