On the evening of 7 August we reached Exham Priory, where the servants assured me that nothing unusual had occurred. The cats, even old Nigger-Man, had been perfectly placid, and not a trap in the house had been sprung. We were to begin exploring on the following dlay, awaiting which I assigned well-appointed rooms to all my guests.
I myself retired in my own tower chamber, with Nigger-Man across my feet. Sleep came quickly, but hideous dreams assailed me. There was a vision of a Roman feast like that of Trimalchio, with a horror in a covered platter. Then came that damnable, recurrent thing about the swineherd and his filthy drove in the twilit grotto. Yet when I awoke it was full daylight, with normal sounds in the house below. The rats, living or spectral, had not troubled me; and Nigger-Man was still quietly asleep. On going down, I found that the same tranquillity had prevailed elsewhere; a condition which one of the assembled servants – a fellow named Thornton, devoted to the psychic – rather absurdly laid to the fact that I had now been shown the thing which certain forces had wished to show me.
All was now ready, and at 11 A .M. our entire group of seven men, bearing powerful electric searchlights and implements of excavation, went down to the sub-cellar and bolted the door behind us. Nigger-Man was with us, for the investigators found no occasion to depise his excitability, and were indeed anxious that he be present in case of obscure rodent manifestations. We noted the Roman inscriptions and unknown altar designs only briefly, for three of the savants had already seen them, and all knew their characteristics. Prime attention was paid to the momentous central altar, and within an hour Sir William Brinton had caused it to tilt backward, balanced by some unknown species of counterweight.
There now lay revealed such a horror as would have overwhelmed us had we not been prepared. Through a nearly square opening in the tiled floor, sprawling on a flight of stone steps so prodigiously worn that it was little more than an inclined plane at the centre, was a ghastly array of human or semi-human bones. Those which retained their collocation as skeletons showed attitudes of panic fear, and over all were the marks of rodent gnawing. The skulls denoted nothing short of utter idiocy, cretinism, or primitive semi-apedom.
Above the hellishly littered steps arched a descending passage seemingly chiselled from the solid rock, and conducting a current of air. This current was not a sudden and noxious rush as from a closed vault, but a cool breeze with something of freshness in it. We did not pause long, but shiveringly began to clear a passage down the steps. It was then that Sir William, examining the hewn walls, made the odd observation that the passage, according to the direction of the strokes, must have been chiselled from beneath.
I must be very deliberate now, and choose my words. After ploughing down a few steps amidst the gnawled bones we saw that there was light ahead; not any mystic phosphorescence, but a filtered daylight which could not come except from unknown fissures in the cliff that over-looked the waste valley. That such fissures had escaped notice from outside was hardly remarkable, for not only is the valley wholly uninhabited, but the cliff is so high and beetling that only an aeronaut could study its face in detail. A few steps more, and our breaths were literally snatched from us by what we saw; so literally that Thornton, the psychic investigator, actually fainted in the arms of the dazed men who stood behind him. Norrys, his plump face utterly white and flabby, simply cried out inarticulately; whilst I think that what I did was to gasp or hiss, and cover my eyes.
The man behind me – the only one of the party older than I – croaked the hackneyed "My God!" in the most cracked voice I ever heard. Of seven cultivated men, only Sir William Brinton retained his composure, a thing the more to his credit because he led the party and must have seen the sight first.
It was a twilit grotto of enormous height, stretching away farther than any eye could see; a subterraneous world of limitless mystery and horrible suggestion. There were buildings and other architectural remains – in one terrified glance I saw a weird pattern of tumuli, a savage circle of monoliths, a low-domed Roman ruin, a sprawling Saxon pile, and an early English edifice of wood – but all these were dwarfed by the ghoulish spectacle presented by the general surface of the ground. For yards about the steps extended an insane tangle of human bones, or bones at least as human as those on the steps. Like a foamy sea they stretched, some fallen apart, but others wholly or partly articulated as skeletons; these latter invariably in postures of daemoniac frenzy, either fighting off some menace or clutching other forms with cannibal intent.
When Dr Trask, the anthropologist, stopped to classify the skulls, he found a degraded mixture which utterly baffled him. They were mostly lower than the Piltdown man in the scale of evolution, but in every case definitely human. Many were of higher grade, and a very few were the skulls of supremely and sensitively developed types. All the bones were gnawed, mostly by rats, but somewhat by others of the half-human drove. Mixed with them were many tiny hones of rats – fallen members of the lethal army which closed the ancient epic.
I wonder that any man among us lived and kept his sanity through that hideous day of discovery. Not Hoffman nor Huysmans could conceive a scene more wildly incredible, more frenetically repellent, or more Gothically grotesque than the twilit grotto through which we seven staggered; each stumbling on revelation after revelation, and trying to keep for the nonce from thinking of the events which must have taken place there three hundred, or a thousand, or two thousand or ten thousand years ago. It was the antechamber of hell, and poor Thornton fainted again when Trask told him that some of the skeleton things must have descended as quadrupeds through the last twenty or more generations.
Horror piled on horror as we began to interpret the architectural remains. The quadruped things – with their occasional recruits from the biped class – had been kept in stone pens, out of which they must have broken in their last delirium of hunger or rat-fear. There had been great herds of them, evidently fattened on the coarse vegetables whose remains could be found as a sort of poisonous ensilage at the bottom of the huge stone bins older than Rome . I knew now why my ancestors had had such excessive gardens – would to heaven I could forget! The purpose of the herds I did not have to ask.
Sir William, standing with his searchlight in the Roman ruin, translated aloud the most shocking ritual I have ever known; and told of the diet of the antediluvian cult which the priests of Cybele found and mingled with their own. Norrys, used as he was to the trenches, could not walk straight when he came out of the English building. It was a butcher shop and kitchen – he had expected that – but it was too much to see familiar English implements in such a place, and to read familiar English graffiti there, some as recent as 1610. I could not go in that building – that building whose daemon activities were stopped only by the dagger of my ancestor Walter de la Poer.
What I did venture to enter was the low Saxon building whose oaken door had fallen, and there I found a terrible row of ten stone cells with rusty bars. Three had tenants, all skeletons of high grade, and on the bony forefinger of one I found a seal ring with my own coat-of-arms. Sir William found a vault with far older cells below the Roman chapel, but these cells were empty. Below them was a low crypt with cases of formally arranged bones, some of them bearing terrible parallel inscriptions carved in Latin, Greek, and the tongue of Phyrgia.
Meanwhile, Dr Trask had opened one of the prehistoric tumuli, and brought to light skulls which were slightly more human than a gorilla's, and which bore indescribably ideographic carvings. Through all this horror my cat stalked unperturbed. Once I saw him monstrously perched atop a mountain of bones, and wondered at the secrets that might lie behind his yellow eyes.
