72. A man sets out to draw the world.
    As the years go by, he peoples a space
    with images of provinces, kingdoms,
    mountains, bays, ships, islands, fishes, rooms,
    instruments, stars, horses, and individuals.
    A short time before he dies, he discovers
    that the patient labyrinth of lines
    traces his own face.
