Painting Trivia

A new feature of Art Weekly is painting trivia in between Sunday posts. Look for the answer to each trivia question the following day under the comments section of the post. What artist said:

"I've got myself a goiter from this strain,
As water gives the cats of Lombardy
Or maybe it is in some other country;
My belly's pushed by force beneath my chin.

My beard toward Heaven, I feel the back of my brain
Upon my neck, I grow the breast of a Harpy;
My brush, above my face continually,
Makes it a splendid floor by dripping down.

My loins have penetrated to my paunch,
My rump's a crupper, as a counterweight,
And pointless the unseeing steps I go.

In front of me my skin is being stretched
While it folds up behind and forms a knot,
And I am bending like a Syrian bow.

And judgement, hence, must grow,
Borne in the mind, peculiar and untrue;
You cannot shoot well when the gun's askew.

John, come to the rescue
Of my dead painting now, and of my honor;
I'm not in a good place, and I'm no painter (5-6)."

The answer is...
