Madame De Sévigné by Virginia Woolf

This great lady, this robust and fertile letter writer, who in our age would probably have been one of the great novelists, takes up presumably as much space in the consciousness of living readers as any figure of her vanished age. But it is more difficult to fix that figure within an outline than so to sum up many of her contemporaries. That is partly because she created her being, not in plays or poems, but in letters--touch by touch, with repetitions, amassing daily trifles, writing down what came into her head as if she were talking. Thus the fourteen volumes of her letters enclose a vast open space, like one of her own great woods; the rides are crisscrossed with the intricate shadows of branches, figures roam down the glades, pass from sun to shadow, are lost to sight, appear again, but never sit down in fixed attitudes to compose a group.

Thus we live in her presence, and often fall, as with living people, into unconsciousness. She goes on talking, we half listen. And then something she says rouses us. We add it to her character, so that the character grows and changes, and she seems like a living person, inexhaustible.
