For 'tis in Life, as 'tis in Painting:
Much may be Right, yet much be Wanting:
From Lines drawn true, our Eye may trace
A Foot, a Knee, a Hand, a Face:
May justly own the Picture wrought
Exact to Rule, exempt from Fault:
Yet if the Colouring be not there,
The  Stroke, the  Air;
To nicest Judgment show the Piece;
At best 'twill only not displease:
It would not gain on  Eye:
would frown, and set it by.
