As the hours wore on and night stealthily and gradually advanced, a monotonous darkness overspread, one after another, the objects discernible to Hermanric from the solitary ground he still occupied. Soon the great city faded into one vast, impenetrable shadow, while the suburbs and the low country around them vanished in the thick darkness that gathered almost perceptibly over the earth. And now the sole object distinctly visible was the figure of a weary sentinel, who stood on the frowning rampart immediately above the rifted wall, and whose drooping figure, propped upon his weapon, was indicated in hard relief against the thin, solitary streak of light still shining in the cold and cloudy wastes of the western sky. But as the night still deepened, this one space of light faded, contracted, vanished, and with it disappeared the sentinel and the line of rampart on which he was posted. The rule of the darkness now became universal. Densely and rapidly it overspread the whole city with startling suddenness; as if the fearful destiny now working its fulfilment in Rome had forced the external appearances of the night into harmony with its own woe-boding nature. Then, as the young Goth still lingered at his post of observation, the long, low, tremulous, absorbing roll of thunder afar off became grandly audible. It seemed to proceed from a distance almost incalculable; to be sounding from its cradle in the frozen north; to be journeying about its ice-girdled chambers in the lonely poles. It deepened rather than interrupted the dreary, mysterious stillness of the atmosphere. The lightning, too, had a summer softness in its noiseless and frequent gleam. It was not the fierce lightning of winter, but a warm, fitful brightness, almost fascinating in its light, rapid recurrence, tinged with the glow of heaven, and not with the glare of hell. There was no wind--no rain; and the air was as hushed as if it slept over chaos in the infancy of a new creation. Among the various objects displayed, instant by instant, by the rapid lightning to the eyes of Hermanric, the most easily and most distinctly visible was the broad surface of the rifted wall. The large, loose stones, scattered here and there at its base, and the overhanging lid of its broad rampart, became plainly though fitfully apparent in the brief moments of their illumination. The lightning had played for some time over that structure of the fortifications, and the bare ground that stretched immediately beyond them, when the smooth prospect which it thus gave by glimpses to view, was suddenly chequered by a flight of birds appearing from one of the lower divisions of the wall, and flitting uneasily to and fro at one spot before its surface.
