Boulevard de l’Hôpital and the Salpêtrière, 1822
"Forty years ago, a rambler who had ventured into that unknown country of the Salpetriere, and who had mounted to the Barriere d’Italie by way of the boulevard, reached a point where it might be said that Paris disappeared. It was no longer solitude, for there were passers-by; it was not the country, for there were houses and streets; it was not the city, for the streets had ruts like highways, and the grass grew in them; it was not a village, the houses were too lofty. What was it, then? It was an inhabited spot where there was no one; it was a desert place where there was some one; it was a boulevard of the great city, a street of Paris; more wild at night than the forest, more gloomy by day than a cemetery."
