Last Instructions to a Painter
After two sittings, now our Lady State 
To end her picture does the third time wait. 
But ere thou fall'st to work, first, Painter, see 
If't ben't too slight grown or too hard for thee. 
Canst thou paint without colors? Then 'tis right: 
For so we too without a fleet can fight. 
Or canst thou daub a signpost, and that ill? 
'Twill suit our great debauch and little skill. 
Or hast thou marked how antic masters limn 
The aly-roof with snuff of candle dim, 
Sketching in shady smoke prodigious tools?
