His feet bore him unawares to the entrance which leads into the dead city. He removed the wooden bar that closed it, and wandered into the ruins beyond. The moon illuminated the pale houses with her white beams, dividing the streets into double-edged lines of silvery white and bluish shadow. This nocturnal day, with its subdued tints, disguised the degradation of the buildings. The mutilated columns, the façades streaked with fugitive lizards, the roofs crumbled in by the eruption, were less noticeable than when beheld under the clear, raw light of the sun. The lost parts were completed by the half-tint of shadow, and here and there one brusque beam of light, like a touch of sentiment in a picture-sketch, marked where a whole edifice had crumbled away. The silent genii of the night seemed to have repaired the fossil city for some representation of fantastic life. At times Octavian fancied that he saw vague human forms in the shadow, but they vanished the moment they approached the edge of the lighted portion of the street. A low whispering, an indefinite hum, floated through the silence. Our promenader at first attributed them to a fluttering in his eyes, to a buzzing in his ears; it might even, he thought, be merely an optical delusion, coupled with the sighing of the sea-breezes, or the flight of some snake or lizard through the nettles, for in nature all things live, even death; all things make themselves heard, even silence. Nevertheless he felt a kind of involuntary terror, a slight trembling, that might have been caused by the cold night air, but which made his flesh creep. Could it be that his comrades, actuated by the same impulses as himself, were seeking him among the ruins? Those dimly seen forms and those indistinct sounds of footsteps! Might it not have been only Max and Fabio walking and chatting together, who had just disappeared round the corner of a cross-road? But Octavian felt to his dismay that this very natural explanation could not be true, and the arguments which he made to himself in favor of it were the reverse of convincing. The solitude and the shadow were peopled with invisible beings whom he was disturbing. He had fallen into the midst of a mystery, and it seemed that they were awaiting his departure in order to commence again. Such were the extravagant ideas that floated through his brain, and obtained no little verisimilitude from the hour, the place, and the thousand alarming details which those can well understand who have ever found themselves alone by night in the midst of some vast ruin.
