Poussin, observing against the dark panelling of the wall a magnificent portrait of a woman, exclaimed aloud, “What a magnificent Giorgione!”

“No,” remarked the old man, “that is only one of my early daubs.”

“Zounds!” cried Poussin naively; “are you the king of painters?”

The old man smiled, as if long accustomed to such homage.  “Maitre Frenhofer,” said Porbus, “could you order up a little of your good Rhine wine for me?”

“Two casks,” answered the host; “one to pay for the pleasure of looking at your pretty sinner this morning, and the other as a mark of friendship.”

“Ah! if I were not so feeble,” resumed Porbus, “and if you would consent to let me see your Beautiful Nut-girl, I too could paint some lofty picture, grand and yet profound, where the forms should have the living life.”

“Show my work!” exclaimed the old man, with deep emotion.  “No, no!  I have still to bring it to perfection.  Yesterday, towards evening, I thought it was finished.  Her eyes were liquid, her flesh trembled, her tresses waved—­she breathed!  And yet, though I have grasped the secret of rendering on a flat canvas the relief and roundness of nature, this morning at dawn I saw many errors.  Ah! to attain that glorious result, I have studied to their depths the masters of color.  I have analyzed and lifted, layer by layer, the colors of Titian, king of light.  Like him, great sovereign of art, I have sketched my figure in light clear tones of supple yet solid color; for shadow is but an accident, —­remember that, young man.  Then I worked backward, as it were; and by means of half-tints, and glazings whose transparency I kept diminishing little by little, I was able to cast strong shadows deepening almost to blackness.  The shadows of ordinary painters are not of the same texture as their tones of light.  They are wood, brass, iron, anything you please except flesh in shadow.  We feel that if the figures changed position the shady places would not be wiped off, and would remain dark spots which never could be made luminous.  I have avoided that blunder, though many of our most illustrious painters have fallen into it.  In my work you will see whiteness beneath the opacity of the broadest shadow.  Unlike the crowd of ignoramuses, who fancy they draw correctly because they can paint one good vanishing line, I have not dryly outlined my figures, nor brought out superstitiously minute anatomical details; for, let me tell you, the human body does not end off with a line.  In that respect sculptors get nearer to the truth of nature than we do.  Nature is all curves, each wrapping or overlapping another.  To speak rigorously, there is no such thing as drawing.  Do not laugh, young man; no matter how strange that saying seems to you, you will understand the reasons for it one of these days.  A line is a means by which man explains to himself the effect of light upon a given object; but there is no such thing as
