It also happens that, if you move along Marozia's compact walls, when you least expect it, you see a crack open and a different city appear. Then, an instant later, it has already vanished. Perhaps everything lies in knowing what words to speak, what actions to perform, and in what order and rhythm; or else someone's gaze, answer, gesture is enough; it is enough for someone to do something for the sheer pleasure of doing it, and for his pleasure to become the pleasure of others: at that moment, all spaces change, all heights, distances; the city is transfigured, becomes crystalline, transparent as a dragonfly.
