as soon as the stranger arrives at the unknown city and his eye penetrates the pine cone of pagodas and garrets and haymows, following the scrawl of canals, gardens, rubbish heaps, he immediately distinguishes which are the princes’ palaces, the high priests’ temples, the tavern, the prison, the slum. This—some say—confirms the hypothesis that each man bears in his mind a city made only of differences, a city without figures and without form, and the individual cities fill it up.
