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 only unbroken blackness.
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 So seething with baffling hints and images was my mind, that all objective matters seemed withdrawn into incalculable distances.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 strown 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 the 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 moonlit 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 on 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 torchlight 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 amnesic 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 dreamt for more than a score of years? What obscure, forgotten iconography could have reproduced each subtle shading and nuance which so persistently, exactly, and unvaryingly besieged my sleeping vision night after night?
