of Constantine the Great by transplanting especially fine blocks of ancient carving from their land city, just as the emperor, in a similar age of decline, stripped Greece and Asia of their finest art to give his new Byzantine capital greater splendours than its own people could create.That the transfer of sculptured blocks had not been more extensive, was doubtless owing to the fact that the land city was not at first wholly abandoned.By the time total abandonment did occur—and it surely must have occurred before the polar Pleistocene was far advanced—the Old Ones had perhaps become satisfied with their decadent art—or had ceased to recognise the superior merit of the older carvings.At any rate, the aeon-silent ruins around us had certainly undergone no wholesale sculptural denudation; though all the best separate statues, like other moveables, had been taken away.
The decadent cartouches and dadoes telling this story were, as I have said, the latest we could find in our limited search.They left us with a picture of the Old Ones shuttling back and forth betwixt the land city in summer and the sea-cavern city in winter, and sometimes trading with the sea-bottom cities off the antarctic coast.By this time the ultimate doom of the land city must have been recognised, for the sculptures shewed many signs of the cold’s malign encroachments.Vegetation was declining, and the terrible snows of the winter no longer melted completely even in midsummer.The saurian livestock were nearly all dead, and the mammals were standing it none too well.To keep on with the work of the upper world it had become necessary to adapt some of the amorphous and curiously cold-resistant shoggoths to land life; a thing the Old Ones had formerly been reluctant to do.The great river was now lifeless, and the upper sea had lost most of its denizens except the seals and whales.All the birds had flown away, save only the great, grotesque penguins.
What had happened afterward we could only guess.How long had the new sea-cavern city survived? Was it still down there, a stony corpse in eternal blackness? Had the subterranean waters frozen at last? To what fate had the ocean-bottom cities of the outer world been delivered? Had any of the Old Ones shifted north ahead of the creeping ice-cap? Existing geology shews no trace of their presence.Had the frightful Mi-Go been still a menace in the outer land world of the north? Could one be sure of what might or might not linger even to this day in the lightless and unplumbed abysses of earth’s deepest waters? Those things had seemingly been able to withstand any amount of pressure—and men of the sea have fished up curious objects at times.And has the killer-whale theory really explained the savage and mysterious scars on antarctic seals noticed a generation ago by Borchgrevingk?
The specimens found by poor Lake did not enter into these guesses, for their geologic setting proved them to have lived at what must have been a very early date in the land city’s history.They were, according to their location, certainly not less than thirty million years old; and we reflected that in their day the sea-cavern city, and indeed the cavern itself, had no existence.They would have remembered an older scene, with lush Tertiary vegetation everywhere, a younger land city of flourishing arts around them, and a great river sweeping northward along the base of the mighty mountains toward a far-away tropic ocean.
And yet we could not help thinking about these specimens—especially about the eight perfect ones that were missing from Lake’s hideously ravaged camp.There was something abnormal about that whole business—the strange things we had tried so hard to lay to somebody’s madness—those frightful graves—the amount and nature of the missing material—Gedney—the unearthly toughness of those archaic monstrosities, and the queer vital freaks the sculptures now shewed the race to have....Danforth and I had seen a good deal in the last few hours, and were prepared to believe and keep silent about many appalling and incredible secrets of primal Nature.
IX.
I have said that our study of the decadent sculptures brought about a change in our immediate objective.This of course had to do with the chiselled avenues to the black inner world, of whose existence we had not known before, but which we were now eager to find and traverse.From the evident scale of the carvings we deduced that a steeply descending walk of about a mile through either of the neighbouring tunnels would bring us to the brink of the dizzy sunless cliffs above the great abyss; down whose side adequate paths, improved by the Old Ones, led to the rocky shore of the hidden and nighted ocean.To behold this fabulous gulf in stark reality was a lure which seemed impossible of resistance once we knew of the thing—yet we realised we must begin the quest at once if we expected to include it on our present flight.
It was now 8 P.M., and we had not enough battery replacements to let our torches burn on forever.We had done so much of our studying and copying below the glacial level that our battery supply had had at least five hours of nearly continuous use; and despite the special dry cell formula would obviously be good for only about four more—though by keeping one torch unused, except for especially interesting or difficult places, we might manage to eke out a safe margin beyond that.It would not do to be without a light in these Cyclopean catacombs, hence in order to make the abyss trip we must give up all further mural deciphering.Of course we intended to revisit the place for days and perhaps weeks of intensive study and photography—curiosity having long ago got the better of horror—but just now we must hasten.Our supply of trail-blazing paper was far from unlimited, and we were reluctant to sacrifice spare notebooks or sketching paper to augment it; but we did let one large notebook go.If worst came to worst, we could resort to rock-chipping—and of course it would be possible, even in case of really lost direction, to work up to full daylight by one channel or another if granted sufficient time for plentiful trial and error.So at last we set off eagerly in the indicated direction of the nearest tunnel.
According to the carvings from which we had made our map, the desired tunnel-mouth could not be much more than a quarter-mile from where we stood; the intervening space shewing solid-looking buildings quite likely to be penetrable still at a sub-glacial level.The opening itself would be in the basement—on the angle nearest the foothills—of a vast five-pointed structure of evidently public and perhaps ceremonial nature, which we tried to identify from our aërial survey of the ruins.No such structure came to our minds as we recalled our flight, hence we concluded that its upper parts had been greatly damaged, or that it had been totally shattered in an ice-rift we had noticed.In the latter case the tunnel would probably turn out to be choked, so that we would have to try the next nearest one—the one less than a mile to the north.The intervening river-course prevented our trying any of the more southerly tunnels on this trip; and indeed, if both of the neighbouring ones were choked it was doubtful whether our batteries would warrant an attempt on the next northerly one—about a mile beyond our second choice.
As we threaded our dim way through the labyrinth with the aid of map and compass—traversing rooms and corridors in every stage of ruin or preservation, clambering up ramps, crossing upper floors and bridges and clambering down again, encountering choked doorways and piles of debris, hastening now and then along finely preserved and uncannily immaculate stretches, taking false leads and retracing our way (in such cases removing the blind paper trail we had left), and once in a while striking the bottom of an open shaft through which daylight poured or trickled down—we were repeatedly tantalised by the sculptured walls along our route.Many must have told tales of immense historical importance, and only the prospect of later visits reconciled us to the need of passing them by.As it was, we slowed down once in a while and turned on our second torch.If we had had more films we would certainly have paused briefly to photograph certain bas-reliefs, but time-consuming hand copying was clearly out of the question.
I come now once more to a place where the temptation to hesitate, or to hint rather than state, is very strong.It is necessary, however, to reveal the rest in order to justify my course in discouraging further exploration.We had wormed our way very close to the computed site of the tunnel’s mouth—having crossed a second-story bridge to what seemed plainly the tip of a pointed wall, and descended to a ruinous corridor especially rich in decadently elaborate and apparently ritualistic sculptures of late workmanship—when, about 8:30 P.M., Danforth’s keen young nostrils gave us the first hint of something unusual.If we had had a dog with us, I suppose we would have been
