No jot nor tittle of these but in its turn
Ministers to perfection of the piece:
Till now, such piece before him, part by part,—
Such prelude ended,—pause our painter may,
Submit his fifty studies one by one,
And in some sort boast "I have served my lords."
But what? And hath he painted once this while?
Or when ye cry, "Produce the thing required,
Show us our picture shall rejoice its niche,
Thy Journey through the Desert done in oils!"—
