Not that any one differed essentially from the earlier specimens we had found. It was something subtler than that. The impression did not come when I looked at one block alone, but only when I ran my eye over several almost simultaneously.
Then, at last, the truth dawned upon me. The curvilinear pattens on many of those blocks were closely related—parts of one vast decorative conception. For the first time in this aeon-shaking waste I had come upon a mass of masonry in its old position—tumbled and fragmentary, it is true, but none the less existing in a very definite sense.
Mounting at a low place, I clambered laboriously over the heap; here and there clearing away the sand with my fingers, and constantly striving to interpret varieties of size, shape, and style, and relationships of design.
After a while I could vaguely guess at the nature of the bygone structure, and at the designs which had once stretched over the vast surfaces masonry. The perfect identity of the whole with some of my dream glimpses appalled and unnerved me.
This was once a cyclopean corridor thirty feet wide and thirty feet tall, paved with octagonal blocks and solidly vaulted overhead. There would have been rooms opening off on the right, and at the farther end one of those strange inclined planes would have wound down to still lower depths.
I started violently as these conceptions occurred to me, for there was more in them than the blocks themselves had supplied. How did I know that this level should have been far underground? How did I know that the plane leading upward should have been behind me? How did I know that the long subterrene passage to the Square of Pillars ought to lie on the left one level above me?
How did I know that the room of machines and the rightward-leading tunnel to the central archives ought to lie two levels below? How did I know that there would be one of those horrible metal-banded trapdoors at the very bottom four levels down? Bewildered by this intrusion from the dream world, I found myself shaking and bathed in a cold perspiration.
Then, as a last, intolerable touch, I felt that faint, insidious stream of cool air trickling upward from a depressed place near the center of the huge heap. Instantly, as once before, my visions faded, and I saw again only the evil moonlight, the brooding desert, and the spreading tumulus of paleogean masonry. Something real and tangible, yet fraught with infinite suggestions of nighted mystery, now confronted me. For that stream of air could argue but one thing—a hidden gulf of great size beneath the disordered blocks on the surface.
My first thought was of the sinister blackfellow legends of vast underground huts among the megaliths where horrors happen and great winds are born. Then thoughts of my own dreams came back, and I felt dim pseudomemories tugging at my mind. What manner of place lay below me? What primal, inconceivable source of age-old myth cycles and haunting nightmares might I be on the brink of uncovering?
It was only for a moment that I hestitated, for more than curiosity and scientific zeal was driving me on and working against my growing fear.
I seemed to move almost automatically, as if in the clutch of some compelling fate. Pocketing my torch, and struggling with a strength that I had not thought I possessed, I wrenched aside first one titan fragment of stone and then another, till there welled up a strong draft whose dampness contrasted oddly with the desert’s dry air. A black rift began to yawn, and at length—when I had pushed away every fragment small enough to budge—the leprous moonlight blazed on an aperture of ample width to admit me.
I drew out my torch and cast a brilliant beam into the opening. Below me was a chaos of tumbled masonry, sloping roughly down toward the north at an angle of about forty-five degrees, and evidently the result of some bygone collapse from above.
Between its surface and the ground level was a gulf of impenetrable blackness at whose upper edge were signs of gigantic, stress-heaved vaulting. At this point, it appeared, the desert’s sands lay directly upon a floor of some titan structure of earth’s youth—how preserved through aeons of geologic convulsion I could not then and cannot now even attempt to guess.
In retrospect, the barest idea of a sudden lone descent into such a doubtful abyss—and at a time when one’s whereabouts were unknown to any living soul—seems like the utter apex of insanity. Perhaps it was—yet that night I embarked without hesitancy upon such a descent.
Again there was manifest that lure and driving of fatality which had all along seemed to direct my course. With torch flashing intermittently to save the battery, I commenced a mad scramble down the sinister, cyclopean incline below the opening—sometimes facing forward as I found good hand and foot holds, and at other times turning to face the heap of megaliths as I clung and fumbled more precariously.
In two directions beside me, distant walls of carven, crumbling masonry loomed dimly under the direct beams of my torch. Ahead, however, was darkness.
I kept no track of time during my downward scramble. So seething with baffling hints and images was my mind that all objective matters seemed withdrawn to incalculable distances. Physical sensation was dead, and even fear remained as a wraith-like, inactive gargoyle leering impotently at me.
Eventually I reached a level floor strewn with fallen blocks, shapeless fragments of stone, and sand and detritus of every kind. On either side—perhaps thirty feet apart—rose massive walls culminating in huge groinings. That they were carved I could just discern, but the nature of the carvings was beyond my perception.
What held me most was the vaulting overhead. The beam from my torch could not reach the roof, but the lower parts of the monstrous arches stood out distinctly. And so perfect was their identity with what I had seen in countless dreams of the elder world, that I trembled actively for the first time.
Behind and high above, a faint luminous blur told of the distant moonlight world outside. Some vague shred of caution warned me that I should not let it out of my sight, lest I have no guide for my return.
I now advanced toward the wall at my left, where the traces of carving were plainest. The littered floor was nearly as hard to traverse as the downward heap had been, but I managed to pick my difficult way.
At one place I heaved aside some blocks and kicked away the detritus to see what the pavement was like, and shuddered at the utter, fateful familiarity of the great octagonal stones whose buckled surface still held roughly together.
Reaching a convenient distance from the wall, I cast the searchlight slowly and carefully over its worn remnants of carving. Some bygone influx of water seemed to have acted on the sandstone surface, while there were curious incrustations which I could not explain.
In places the masonry was very loose and distorted, and I wondered how many aeons more this primal, hidden edifice could keep its remaining traces of form amidst earth’s heavings.
But it was the carvings themselves that excited me most. Despite their time-crumbled state, they were relatively easy to trace at close range; and the complete, intimate familiarity of every detail almost stunned my imagination. That the major attributes of this hoary masonry should be familiar, was not beyond normal credibility.
Powerfully impressing the weavers of certain myths, they had become embodied in a stream of cryptic lore which, somehow, coming to my notice during the amnesiac period, had evoked vivid images in my subconscious mind.
But how could I explain the exact and minute fashion in which each line and spiral of these strange designs tallied with what I had dreamed for more than a score of years? What obscure, forgotten oconography could have reproduced each subtle shading and
nuance
which so persistently, exactly, and unvaryingly beseiged my sleeping vision night after night?
For this was no chance or remote resemblance. Definitely and absolutely, the millennially ancient, aeon-hidden corridor in which I stood was the original of something I knew in sleep as intimately as I knew my own house in Crane Street, Arkham. True, my dreams showed the place in its undecayed prime; but the identity was no less real on that account. I was wholly and horribly oriented.
The particular structure I was in was known to me. Known, too, was its place in that terrible elder city of dream. That I could visit unerringly any point in that structue or in that city which had escaped the changes and devastations of uncounted ages, I realized with hideous and instinctive certainty. What in Heaven’s name could all this mean? How had I come to know what I knew? And what awful reality could lie behind those antique tales of the beings who had dwelt in this labyrinth of primordial stone?
Words can convey only fractionally the welter of dread and bewilderment which ate at my spirit. I knew this place. I knew what lay below me, and what had lain overhead before the myriad towering stories had fallen to dust and debris and the desert. No need now, I thought with a shudder, to keep that faint blur of moonlight in view.
I was torn betwixt a longing to flee and a feverish mixture of burning curiosity and driving fatality. What had happened to this monstrous megalopolis of old in the millions of years since the time of my dreams? Of the subterrene mazes which had underlain the city and linked all the titan towers, how much had still survived the writhings of earth’s crust?
Had I come upon a whole buried world of unholy archaism? Could I still find the house of the writing master, and the tower where S’gg’ha, the captive mind from the star-headed vegetable carnivores of Antarctica, had chiseled certain pictures on the blank spaces of the walls?
Would the passage at the second level down to the hall of the alien minds, be still unchoked and traversable? In that hall the captive mind of an incredible entity—a half-plastic denizen of the hollow interior of an unknown trans-Plutonian planet eighteen million years in the future—had kept a certain thing which it had modeled from clay.
I shut my eyes and put my hand to my head in a vain, pitiful effort to drive these insane dream fragments from my consciousness. Then, for the first time I felt acutely the coolness, motion, and dampness of the surrounding air. Shuddering, I realized that a vast chain of aeon-dead black gulfs must indeed be yawning somewhere beyond and below me.
I thought of the frightful chambers and corridors and inclines as I recalled them from my dreams. Would the way to the central archives still be open? Again that driving fatality tugged insistently at my brain as I recalled the awesome records that once lay cased in those rectagular vaults of rustless metal.
There, said the dreams and legends, had reposed the whole history, past and future, of the cosmic space-time continuum—written by captive minds from every orb and every age in the solar system. Madness, of course—but had I not now stumbled into a nighted world as mad as I?
I thought of the locked metal shelves, and of the curious knob twistings needed to open each one. My own came vividly into my consciousness. How often had I gone through that intricate routine of varied turns and pressures in the terrestrial vertebrate section on the lowest level! Every detail was fresh and familiar.
If there were such a vault as I had dreamed of, I could open it in a moment. It was then that madness took me utterly. An instant later, and I was leaping and stumbling over the rocky debris toward the well-remembered incline to the depths below.
VII
From that point forward my impressions are scarcely to be relied on—indeed, I still possess a final, desperate hope that they all form parts of some demoniac dream or illusion born of delirium. A fever raged in my brain, and everything came to me through a kind of haze—sometimes only intermittently.
The rays of my torch shot feebly into the engulfing blackness, bringing phantasmal flashes of hideously familiar walls and carvings, all blighted with the decay of ages. In one place a tremendous mass of vaulting had fallen, so that I had to clamber over a mighty mound of stones reaching almost to the ragged, grotesquely stalactited roof.
It was all the ultimate apex of nightmare, made worse by that blasphemous tug of pseudomemory. One thing only was unfamiliar, and that was my own size in relation to the monstrous masonry. I felt oppressed by a sense of unwonted smallness, as if the sight of these towering walls from a mere human body was something wholly new and abnormal. Again and again I looked nervously down at myself, vaguely disturbed by the human form I possessed.
Onward through the blackness of the abyss I leaped, plunged and staggered—often falling and bruising myself, and once nearly shattering my torch. Every stone and corner of that demoniac gulf was known to me, and at many points I stopped to cast beams of light through choked and crumbling, yet familiar, archways.
Some rooms had totally collapsed; others were bare, or debris-filled. In a few I saw masses of metal—some fairly intact, some broken, and some crushed or battered—which I recognized as the colossal pedestals or tables of my dreams. What they could in truth have been, I dared not guess.
I found the downward incline and began its descent—though after a time halted by a gaping, ragged chasm whose narrowest point could not be much less than four feet across. Here the stone-work had fallen through, revealing incalculable inky depths beneath.
I knew there were two more cellar levels in this titan edifice, and trembled with fresh panic as I recalled the metal-clamped trapdoor on the lowest one. There could be no guards now—for what had lurked beneath had long since done its hideous work and sunk into its long decline. By the time of the posthuman beetle race it would be quite dead. And yet, as I thought of the native legends, I trembled anew.
It cost me a terrible effort to vault that yawning chasm, since the littered floor prevented a running start—but madness drove me on. I chose a place close to the left-hand wall—where the rift was least wide and the landing spot reasonably clear of dangerous debris—and after one frantic moment reached the other side in safety.
At last, gaining the lower level, I stumbled on past the archway of the room of machines, within which were fantastic ruins of metal, half buried beneath fallen vaulting. Everything was where I knew it would be, and I climbed confidently over the heaps which barred the entrance of a vast transverse corridor. This, I realized, would take me under the city to the central archives.
