To see the moment holds a madrigal, 
To find some cloistered place, some hermitage 
For free devices, some deliberate cage 
Wherein to keep wild thoughts like birds in thrall; 
To eat sweet honey and to taste black gall, 
To fight with form, to wrestle and to rage, 
Till at the last upon the conquered page 
The shadows of created Beauty fall. 

This is the sonnet, this is all delight 
Of every flower that blows in every Spring, 
And all desire of every desert place; 
This is the joy that fills a cloudy night 
When bursting from her misty following, 
A perfect moon wins to an empty space.
