CHAPTER 12.
THE PASSAGE OF THE WALL.
'A fair night this, Balbus! All moonlight and no mist! I was posted last evening at the Ostian Gate, and was half choked by the fog.'
'If you were posted last night at the Ostian Gate, you were better placed than you are now. The ramparts here are as lonely as a ruin in the provinces. Nothing behind us but the back of the Pincian Mount; nothing before us but the empty suburbs; nothing at each side of us but brick and stone; nothing at our posts but ourselves. May I be crucified like St. Peter, if I believe that there is another place on the whole round of the walls possessed of such solitary dulness as this!'
'You are a man to find something to complain of, if you were lodged in one of the palaces yonder. The place is solitary enough, it is true; but whether it is dull or not depends on ourselves, its most honourable occupants. I, for one, am determined to promote its joviality by the very praiseworthy exertion of obliging you, my discontented friend, with an inexhaustible series of those stories for which, I may say, without arrogance, I am celebrated throughout the length and breadth of all the barracks of Rome.'
'You may tell as many stories as you please, but do not imagine that I will make one of your audience.'
'You are welcome to attend to me or not, as you choose. Though you do not listen, I shall still relate my stories by way of practice. I will address them to the walls, or to the air, or to the defunct gods and goddesses of antiquity, should they happen at this moment to be hovering over the city in a rage, as some of the unconverted would have us believe; or to our neighbours the Goths, if they are seized with a sudden desire to quite their encampments, and obtain a near view of the fortifications that they are so discreetly unwilling to assault. Or, these materials for a fit and decent auditory failing me, I will tell my stories to the most attentive of all listeners--myself.'
And the sentinel, without further delay, opened his budget of anecdotes, with the easy fluency of of a man who possessed a well-placed confidence in the perfection of his capacities for narration. Determined that his saturnine colleague should hear him, though he would not give him his attention, he talked in a raised voice, pacing briskly backwards and forwards over the space of his allotted limits, and laughing with ludicrous regularity and complacency at every jest that he happened to make in the course of his ill-rewarded narrative. He little thought, as he continued to proceed in his tale that its commencement had been welcomed by an unseen hearer, with emotions widely different from those which had dictated the observations of the unfriendly companion of his watch.
True to his determination, Ulpius, with part of the wages which he had hoarded in Numerian's service, had procured a small lantern from a shop in one of the distant quarters of Rome; and veiling its light in a piece of coarse, thick cloth, had proceeded by the solitary pathway to his second night's labour at the wall. He arrived at the breach, at the commencement of the dialogue above related, and heard with delight the sentinel's noisy resolution to amuse his companion in spite of himself. The louder and the longer the man talked, the less probable was the chance that the Pagan's labours in the interior of the wall would be suspected or overheard.
Softly clearing away the brushwood at the entrance of the hole that he had made the night before, Ulpius crept in as far as he had penetrated on that occasion; and then, with mingled emotions of expectation and apprehension which affected him so powerfully, that he was for the moment hardly master of his actions, he slowly and cautiously uncovered his light.
His first glance was intuitively directed to the cavity that opened beneath him. He saw immediately that it was less important, both in size and depth, than he had imagined it to be. The earth at this particular place had given way beneath the foundations of the wall, which had sunk down, deepening the chasm by their weight, into the yielding ground beneath them. A small spring of water (probably the first cause of the sinking in the earth) had bubbled up into the space in the brick-work, which bit by bit, and year by year, it had gradually undermined. Nor did it remain stagnant at this place. It trickled merrily and quietly onward--a tiny rivulet, emancipated from one prison in the ground only to enter another in the wall, bounded by no grassy banks, brightened by no cheerful light, admired by no human eye, followed in its small course through the inner fissures in the brick by no living thing but a bloated toad, or a solitary lizard: yet wending as happily on its way through darkness and ruin, as its sisters who were basking in the sunlight of the meadows, or leaping in the fresh breezes of the open mountain side.
Raising his eyes from the little spring, Ulpius next directed his attention to the prospect above him.
Immediately over his head, the material of the interior of the wall presented a smooth, flat, hard surface, which seemed capable of resisting the most vigorous attempts at its destruction; but on looking round, he perceived at one side of him and further inwards, an appearance of dark, dimly-defined irregularity, which promised encouragingly for his intended efforts. He descended into the chasm of the rivulet, crawled up on a heap of crumbling brick-work, and gained a hole above it, which he immediately began to widen, to admit of his passage through. Inch by inch, he enlarged the rift, crept into it, and found himself on a fragment of the bow of one of the foundation arches, which, though partly destroyed, still supported itself, isolated from all connection with the part of the upper wall which it had once sustained, and which had gradually crumbled away into the cavities below.
He looked up. An immense rift soared above him, stretching its tortuous ramifications, at different points, into every part of the wall that was immediately visible. The whole structure seemed, at this place, to have received a sudden and tremendous wrench. But for the support of the sounder fortifications at each side of it, it could not have sustained itself after the shock. The Pagan gazed aloft, into the fearful breaches which yawned above him, with ungovernable awe. His small, fitful light was not sufficient to show him any of their terminations. They looked, as he beheld them in dark relief against the rest of the hollow part of the wall, like mighty serpents twining their desolating path right upward to the ramparts above; and he, himself, as he crouched on his pinnacle with his little light by his side, was reduced by the wild grandeur, the vast, solemn gloom of the obscure, dusky, and fantastic objects around him, to the stature of a pigmy. Could he have been seen from the ramparts high overhead, as he now peered down behind his lantern into the cavities and irregularities below him, he would have looked, with his flickering light, like a mole led by a glow-worm.
He paused to consider his next movements. In a stationary position, the damp coldness of the atmosphere was almost insupportable, but he attained a great advantage by his present stillness: he could listen undisturbed by the noises made by the bricks which crumbled from under him, if he advanced.
Ere long, he heard a thin, winding, long-drawn sound, now louder, now softer; now approaching, now retreating; now verging towards shrillness, now quickly returning to a faint, gentle swell. Suddenly this strange unearthly music was interrupted by a succession of long, deep, rolling sounds, which travelled grandly about the fissures above, like prisoned thunderbolts striving to escape. Utterly ignorant that the first of these noises was occasioned by the night wind winding through the rents in the brick of the outer wall beyond him; and the second, by the echoes produced in the irregular cavities above, by the footfall of the sentries overhead--roused by the influence of the place, and the mystery of his employment, to a pitch of fanatic exaltation, which for the moment absolutely unsteadied his reason--filled with the frantic enthusiasm of his designs, and the fearful legends of invisible beings and worlds which made the foundation of his worship, Ulpius conceived, as he listened to the sounds around and above, that the gods of antiquity were now in viewless congregation hovering about him, and calling to him in unearthly voices and in an unknown tongue, to proceed upon his daring enterprise, in the full assurance of its near and glorious success.
