Absolutely nothing untoward was found, although we could not repress a thrill at the knowledge that this vault was built by Roman hands. Every low arch and massive pillar was Roman – not the debased Romanesque of the bungling Saxons, but the severe and harmonious classicism of the age of the Caesars; indeed, the walls abounded with inscriptions familiar to the antiquarians who had repeatedly explored the place – things like "P. GETAE. PROP… TEMP… DONA…" and "L. PRAEG… VS… PONTIFI… ATYS…"
The reference to Atys made me shiver, for I had read Catullus and knew something of the hideous rites of the Eastern god, whose worship was so mixed with that of Cybele. Norrys and I, by the light of lanterns, tried to interpret the odd and nearly effaced designs on certain irregularly rectangular blocks of stone generally held to be altars, but could make nothing of them. We remembered that one pattern, a sort of rayed sun, was held by students to imply a non-Roman origin suggesting that these altars had merely been adopted by the Roman priests from some older and perhaps aboriginal temple on the same site. On one of these blocks were some brown stains which made me wonder. The largest, in the centre of the room, had certain features on the upper surface which indicated its connection with fire – probably burnt offerings.
Such were the sights in that crypt before whose door the cats howled, and where Norrys and I now determined to pass the night. Couches were brought down by the servants, who were told not to mind any nocturnal actions of the cats, and Nigger-Man was admitted as much for help as for companionship. We decided to keep the great oak door – a modern replica with slits for ventilation – tightly closed; and, with this attended to, we retired with lanterns still burning to await whatever might occur.
The vault was very deep in the foundations of the priory, and undoubtedly far down on the face of the beetling limestone cliff overlooking the waste valley. That it had been the goal of the scuffling and unexplainable rats I could not doubt, though why, I could not tell. As we lay there expectantly, I found my vigil occasionally mixed with half-formed dreams from which the uneasy motions of the cat across my feet would rouse me.
These dreams were not wholesome, but horribly like the one I had had the night before. I saw again the twilit grotto, and the swineherd with his unmentionable fungous beasts wallowing in filth, and as I looked at these things they seemed nearer and more distinct – so distinct that I could almost observe their features. Then I did observe the flabby features of one of them – and awakened with such a scream that Nigger-Man started up, whilst Capt. Norrys, who had not slept, laughed considerably. Norrys might have laughed more – or perhaps less – had he known what it was that made me scream. But I did not remember myself till later. Ultimate horror often paralyses memory in a merciful way.
Norrys waked me when the phenomena began. Out of the same frightful dream I was called by his gentle shaking and his urging to listen to the cats. Indeed, there was much to listen to, for beyond the closed door at the head of the stone steps was a veritable nightmare of feline yelling and clawing, whilst Nigger-Man, unmindful of his kindred outside, was running excitedly round the bare stone walls, in which I heard the same babel of scurrying rats that had troubled me the night before.
An acute terror now rose within me, for here were anomalies which nothing normal could well explain. These rats, if not the creatures of a madness which I shared with the cats alone, must be burrowing and sliding in Roman walls I had thought to be solid limestone blocks … unless perhaps the action of water through more than seventeen centuries had eaten winding tunnels which rodent bodies had worn clear and ample … But even so, the spectral horror was no less; for if these were living vermin why did not Norrys hear their disgusting commotion? Why did he urge me to watch Nigger-Man and listen to the cats outside, and why did he guess wildly and vaguely at what could have aroused them?
By the time I had managed to tell him, as rationally as I could, what I thought I was hearing, my ears gave me the last fading impression of scurrying; which had retreated still downward, far underneath this deepest of sub-cellars till it seemed as if the whole cliff below were riddled with questing rats. Norrys was not as sceptical as I had anticipated, but instead seemed profoundly moved. He motioned to me to notice that the cats at the door had ceased their clamour, as if giving up the rats for lost; whilst Nigger-Man had a burst of renewed restlessness, and was clawing frantically around the bottom of the large stone altar in the centre of the room, which was nearer Norrys' couch than mine.
My fear of the unknown was at this point very great. Something astounding had occurred, and I saw that Capt. Norrys, a younger, stouter, and presumably more naturally materialistic man, was affected fully as much as myself – perhaps because of his lifelong and intimate familiarity with local legend. We could for the moment do nothing but watch the old black cat as he pawed with decreasing fervour at the base of the altar, occasionally looking up and mewing to me in that persuasive manner which he used when he wished me to perform some favour for him.
Norrys now took a lantern close to the altar and examined the place where Nigger-Man was pawing; silently kneeling and scraping away the lichens of the centuries which joined the massive pre-Roman block to the tessellated floor. He did not find anything, and was about to abandon his efforts when I noticed a trivial circumstance which made me shudder, even though it implied nothing more than I had already imagined.
I told him of it, and we both looked at its almost imperceptible manifestation with the fixedness of fascinated discovery and acknowledgment. It was only this – that the flame of the lantern set down near the altar was slightly but certainly flickering from a draught of air which it had not before received, and which came indubitably from the crevice between floor and altar where Norrys was scraping away the lichens.
We spent the rest of the night in the brilliantly-lighted study, nervously discussing what we should do next. The discovery that some vault deeper than the deepest known masonry of the Romans underlay this accursed pile, some vault unsuspected by the curious antiquarians of three centuries, would have been sufficient to excite us without any background of the sinister. As it was, the fascination became two-fold; and we paused in doubt whether to abandon our search and quit the priory forever in superstitious caution, or to gratify our sense of adventure and brave whatever horrors might await us in the unknown depths.
By morning we had compromised, and decided to go to London to gather a group of archaeologists and scientific men fit to cope with the mystery. It should be mentioned that before leaving the sub-cellar we had vainly tried to move the central altar which we now recognized as the gate to a new pit of nameless fear. What secret would open the gate, wiser men than we would have to find.
During many days in London Capt. Norrys and I presented our facts, conjectures, and legendary anecdotes to five eminent authorities, all men who could be trusted to respect any family disclosures which future explorations might develop. We found most of them little disposed to scoff but, instead, intensely interested and sincerely sympathetic. It is hardly necessary to name them all, but I may say that they included Sir William Brinton, whose excavations in the Troad excited most of the world in their day. As we all took the train for Anchester I felt myself poised on the brink of frightful revelations, a sensation symbolized by the air of mourning among the many Americans at the unexpected death of the President on the other side of the world.
