John Ruskin,
Love's Meinie: Three Lectures on Greek and English Birds
“ And accordingly, when I now show you this sketch of my favorite Holbein, and tell you that it is entirely disgraceful he should not know what a wing was, better, I don't mean that it is disgraceful he should not know the anatomy of it, but that he should never have looked at it to see how the feathers lie. Now Holbein paints men gloriously, but never looks at birds; Gibbons, the wood-cutter, carves birds, but can't men;—of the two faults the last is the worst; but the right is in looking at the whole of nature in due comparison, and with universal candor and tenderness. ”
