If you draw a narrow street in perspective in portrait, you get four triangles: one on the left and one on right with the houses receding toward the horizon, the street at the bottom and a ragged V-shaped area at the top. When you draw another street and then another, the V-shaped area (the sky part) you are left with is different each time depending on the jagged outline of the rooftops, like the space between the letters of an alphabet. George Hendrik Breitner (1857-1923) drew, painted and photographed these alleyways. Or should I say photographed, drew and painted them, or even painted, photographed and drew them?
