One encounters in the streets, late at night on the evenings of fetes, the most strange and bizarre passers-by. Do these nights of popular celebration cause ancient and forgotten avatars to stir in the depths of the human soul? This evening, in the movement of the sweaty and excited crowd, I am certain that I passed between the masks of the liberated Bythinians and encountered the courtesans of the Roman decadence. There emerged, this evening, from that swarming esplanade of Des Invalides - amid the crackle of fireworks, the shooting stars, the stink of frying, the hiccuping of drunkards and the reeking atmosphere of menageries - the wild effusions of one of Nero's festivals. It was like the odour of a May evening on the Basso-Porto of Naples. It was easy to believe that the faces in that crowd were Sicilian.
