A woman reads in the lower left-hand corner of the painting. She reads at the side of the bend in the brook under the shadow of a tree growing on the opposite bank. In the center, a patch of light bursts from the sky off in the distance, and two figures—are they fauns?—sit in the shadows underneath trees. She is smaller than the trees in the Forest of Fontainebleau, smaller even than the stone that juts out over the stream. Because she is human, she draws our attention. She is not nude. Her gaze does not capture ours; she is reading.

She is reading, and perhaps we would scold her for not paying attention to nature. “Look at the trees!” we might exhort, much in the same way that we scold friends on cellphones. “Look up!” How little things change in 200 years.
And yet, that rock that the stream has not worn away is like a fulcrum; it balances the reading woman and the rest of the world. Literature vs. Nature. Or maybe a portrayal of nature balanced against nature itself. Much like me, today, at the museum. I could be walking on a trail, along a beach, or on a sidewalk that borders the Thames. I am not. I am in the National Gallery, looking at paintings and writing about what I see.
Perhaps you could read the painting as a dream: the forest is what the woman reads about. Everything above the thin sward of grass where she reads is the thought ignited by the words in her book. Or perhaps Corot wants to tell us that a book has the same weight as everything else in the painting. That may be a warning as well—literature (what kind of literature? genre fiction? epic poetry? something Pynchon hasn’t written yet?) is going to replace nature.
I think of it as a challenge. Write something that can match nature. I love the made thing, the work of hands, whether it is an almond croissant or a cathedral. When we make beautiful things, we transcend the ingredients of our craft. And this: write something that keeps her reading. Yes, writing is about me—my words! my vision!—but what else matters more than that woman by the brook? I write for you.
