How such a painter sets himself to paint?
Suppose that Joseph, Mary and her Babe
A-journeying to Egypt, prove the piece:
Why, first he sedulously practiseth,
This painter,—girding loin and lighting lamp,—
On what may nourish eye, make facile hand;
Getteth him studies (styled by draughtsmen so)
From some assistant corpse of Jew or Turk
Or, haply, Molinist, he cuts and carves,—
This Luca or this Carlo or the like.
