“ Nothing oppresses the heart like symmetry. It is because symmetry is ennui, and ennui is at the very foundation of grief. Despair yawns. Something more terrible than a hell where one suffers may be imagined, and that is a hell where one is bored. ”
 Victor Hugo, Les Misérables (1862). copy citation

“As far as the eye could see, one could perceive nothing but the abattoirs, the city wall, and the fronts of a few factories, resembling barracks or monasteries; everywhere about stood hovels, rubbish, ancient walls blackened like cerecloths, new white walls like winding-sheets; everywhere parallel rows of trees, buildings erected on a line, flat constructions, long, cold rows, and the melancholy sadness of right angles. Not an unevenness of the ground, not a caprice in the architecture, not a fold. The ensemble was glacial, regular, hideous. Nothing oppresses the heart like symmetry. It is because symmetry is ennui, and ennui is at the very foundation of grief. Despair yawns. Something more terrible than a hell where one suffers may be imagined, and that is a hell where one is bored. If such a hell existed, that bit of the Boulevard de l’Hôpital might have formed the entrance to it.
Nevertheless, at nightfall, at the moment when the daylight is vanishing, especially in winter, at the hour when the twilight breeze tears from the elms their last russet leaves, when the darkness is deep and starless, or when the moon and the wind are making openings in the clouds and losing themselves in the shadows, this boulevard suddenly becomes frightful.” source
