That the summit of the second line of defence has been gained is suddenly made known by a contrasting wind from a new quarter, coming over with the curve of a cascade. These novel gusts raise a sound from the whole camp or castle, playing upon it bodily as upon a harp. It is with some difficulty that a foothold can be preserved under their sweep. Looking aloft for a moment I perceive that the sky is much more overcast than it has been hitherto, and in a few instants a dead lull in what is now a gale ensues with almost preternatural abruptness. I take advantage of this to sidle down the second counterscarp, but by the time the ditch is reached the lull reveals itself to be but the precursor of a storm. It begins with a heave of the whole atmosphere, like the sigh of a weary strong man on turning to re-commence unusual exertion, just as I stand here in the second fosse. That which now radiates from the sky upon the scene is not so much light as vaporous phosphorescence.
The wind, quickening, abandons the natural direction it has pursued on the open upland, and takes the course of the gorge’s length, rushing along therein helter-skelter, and carrying thick rain upon its back. The rain is followed by hailstones which fly through the defile in battalions—rolling, hopping, ricochetting, snapping, clattering down the shelving banks in an undefinable haze of confusion. The earthen sides of the fosse seem to quiver under the drenching onset, though it is practically no more to them than the blows of Thor upon the giant of Jotun-land. It is impossible to proceed further till the storm somewhat abates, and I draw up behind a spur of the inner scarp, where possibly a barricade stood two thousand years ago; and thus await events.

The roar of the storm can be heard travelling the complete circuit of the castle—a measured mile—coming round at intervals like a circumambulating column of infantry. Doubtless such a column has passed this way in its time, but the only columns which enter in these latter days are the columns of sheep and oxen that are sometimes seen here now; while the only semblance of heroic voices heard are the utterances of such, and of the many winds which make their passage through the ravines.
The expected lightning radiates round, and a rumbling as from its subterranean vaults—if there are any—fills the castle. The lightning repeats itself, and, coming after the aforesaid thoughts of martial men, it bears a fanciful resemblance to swords moving in combat. It has the very brassy hue of the ancient weapons that here were used. The so sudden entry upon the scene of this metallic flame is as the entry of a presiding exhibitor who unrolls the maps, uncurtains the pictures, unlocks the cabinets, and effects a transformation by merely exposing the materials of his science, unintelligibly cloaked till then. The abrupt configuration of the bluffs and mounds is now for the first time clearly revealed—mounds whereon, doubtless, spears and shields have frequently lain while their owners loosened their sandals and yawned and stretched their arms in the sun. For the first time, too, a glimpse is obtainable of the true entrance used by its occupants of old, some way ahead.
There, where all passage has seemed to be inviolably barred by an almost vertical façade, the ramparts are found to overlap each other like loosely clasped fingers, between which a zigzag path may be followed—a cunning construction that puzzles the uninformed eye. But its cunning, even where not obscured by dilapidation, is now wasted on the solitary forms of a few wild badgers, rabbits, and hares. Men must have often gone out by those gates in the morning to battle with the Roman legions under Vespasian; some to return no more, others to come back at evening, bringing with them the noise of their heroic deeds. But not a page, not a stone, has preserved their fame.

Acoustic perceptions multiply to-night. We can almost hear the stream of years that have borne those deeds away from us. Strange articulations seem to float on the air from that point, the gateway, where the animation in past times must frequently have concentrated itself at hours of coming and going, and general excitement. There arises an ineradicable fancy that they are human voices; if so, they must be the lingering air-borne vibrations of conversations uttered at least fifteen hundred years ago. The attention is attracted from mere nebulous imaginings about yonder spot by a real moving of something close at hand.
I recognize by the now moderate flashes of lightning, which are sheet-like and nearly continuous, that it is the gradual elevation of a small mound of earth. At first no larger than a man’s fist it reaches the dimensions of a hat, then sinks a little and is still. It is but the heaving of a mole who chooses such weather as this to work in from some instinct that there will be nobody abroad to molest him. As the fine earth lifts and lifts and falls loosely aside fragments of burnt clay roll out of it—clay that once formed part of cups or other vessels used by the inhabitants of the fortress.
The violence of the storm has been counterbalanced by its transitoriness. From being immersed in well-nigh solid media of cloud and hail shot with lightning, I find myself uncovered of the humid investiture and left bare to the mild gaze of the moon, which sparkles now on every wet grass-blade and frond of moss.
