Note 48 — NUMERICAL CATALOGUE, WITH BIOGRAPHICAL AND DESCRIPTIVE NOTES

"So in N. Poussin's 'Phocion' (40) the shadow of the stick on the stone in the right-hand corner, is shaded off and lost, while you see the stick plainly all the way. In nature's sunlight it would have been the direct reverse: you would have seen the shadow black and sharp all the way down; but you would have had to look for the stick, which in all probability would in several places have been confused with the stone behind it" (ibid.).
