The tendinous part of the mind, so to speak, is more developed in winter; the fleshy, in summer. I should say winter had given the bone and sinew to Literature, summer the tissues and blood. – John Burroughs, “The Snow-Walkers,” 1866

In winter there is no heat, no light, no noon, evening touches morning, there is fog, and mist, the window is frosted, and you cannot see clearly. The sky is but the mouth of a cave. The whole day is the cave…. Frightful season! Winter changes into stone the water of heaven and the heart of man. – Victor Hugo, Les Misérables: Fantine, translated from French by Chas. E. Wi

In the winter she curls up around a good book and dreams away the cold. – Ben Aaronovitch, Broken Homes
