Classic Poem

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 colours? 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?
'Twill serve this race of drunkards, pimps, and fools.
