and knew by this it opened into the free air.
All of half a mile in diameter was this shaft, and ringed regularly along its height by wide amethystine bands — like rings of a hollow piston. They were, in color, replicas of that I had glimpsed before our descent into this place and against whose gleaming cataracts the outlines of the incredible city had lowered. And they were in motion, spinning smoothly, and swiftly.
Only one swift glance I gave them, my eyes held by a most extraordinary — edifice — altar — machine — I could not find the word for it — then.
Its base was a scant hundred yards from where we had paused and concentric with the sides of the pit. It stood upon a thick circular pedestal of what appeared to be cloudy rock crystal supported by hundreds of thick rods of the same material.
Up from it lifted the structure, a thing of glistening cones and spinning golden disks; fantastic yet disquietingly symmetrical; bizarre as an angled headdress worn by a mountainous Javanese god — yet coldly, painfully mathematical. In every direction the cones pointed, seemingly interwoven of strands of metal and of light.
What was their color? It came to me — that of the mysterious element which stains the sun’s corona, that diadem seen only when our day star is in eclipse; the unknown element which science has named coronium, which never yet has been found on earth and that may be electricity in its one material form; electricity that is ponderable; force whose vibrations are keyed down to mass; power transmuted into substance.
Thousands upon thousands the cones bristled, pyramiding to the base of one tremendous spire that tapered up almost to the top of the shaft itself.
In their grouping the mind caught infinite calculations carried into infinity; an apotheosis of geometry compassing the rhythms of unknown spatial dimensions; concentration of the equations of the star hordes.
The mathematics of the Cosmos.
From the left of the crystalline base swept an enormous sphere. It was twice the height of a tall man, and it was a paler blue than any of these Things I had seen, almost, indeed, an azure; different, too, in other subtle, indefinable ways.
Behind it glided a pair of the pyramidal shapes, their pointed tips higher by a yard or more than the top of the sphere. They paused — regarding us. Out from the opposite arc of the crystal pedestal moved six other globes, somewhat smaller than the first and of a deep purplish luster.
They separated, lining up on each side of the leader now standing a little in advance of the twin tetrahedrons, rigid and motionless as watching guards.
There they stood — that enigmatic row, intent, studying us beneath their god or altar or machine of cones and disks within their cylinder walled with light.
And at that moment there crystallized within my consciousness the sublimation of all the strangenesses of all that had gone before, a panic loneliness as though I had wandered into an alien world — a world as unfamiliar to humanity, as unfamiliar with it as our own would seem to a thinking, mobile crystal adrift among men.
Norhala raised her white arms in salutation; from her throat came a lilting theme of her weirdly ordered, golden chanting. Was it speech, I wondered; and if so — prayer or entreaty or command?
The great sphere quivered and undulated. Swifter than the eye could follow it dilated; opened!
Where the azure globe had been, flashed out a disk of flaming splendors, the very secret soul of flowered flame! And simultaneously the pyramids leaped up and out behind it — two gigantic, four-rayed stars blazing with cold blue fires.
The green auroral curtainings flared out, ran with streaming radiance — as though some Spirit of Jewels had broken bonds of enchantment and burst forth jubilant, flooding the shaft with its freed glories. Norhala’s song ceased; an arm dropped down upon the shoulders of Ruth.
Then woman and girl began to float toward the radiant disk.
As one, the three of us sprang after them. I felt a shock that was like a quick, abrupt tap upon every nerve and muscle, stiffening them into helpless rigidity.
Paralyzing that sharp, unseen contact had been, but nothing of pain followed it. Instead it created an extraordinary acuteness of sight and hearing, an abnormal keying up of the observational faculties, as though the energy so mysteriously drawn from our motor centers had been thrown back into the sensory.
I could take in every minute detail of the flashing miracle of gemmed fires and its flaming ministers. Halfway between them and us Norhala and Ruth drifted; I could catch no hint of voluntary motion on their part and knew that they were not walking, but were being borne onward by some manifestation of that same force which held us motionless.
I forgot them in my contemplation of the Disk.
It was oval, twenty feet in height, I judged, and twelve in its greatest width. A broad band, translucent as sun golden chrysolite, ran about its periphery.
Set within this zodiac and spaced at mathematically regular intervals were nine ovoids of intensely living light. They shone like nine gigantic cabochon cut sapphires; they ranged from palest, watery blue up through azure and purple and down to a ghostly mauve shot with sullen undertones of crimson.
In each of them was throned a flame that seemed the very fiery essence of vitality.
The — BODY— was convex, swelling outward like the boss of a shield; shimmering rosy-gray and crystalline. From the vital ovoids ran a pattern of sparkling threads, irised and brilliant as floss of molten jewels; converging with interfacings of spirals, of volutes and of triangles into the nucleus.
And that nucleus, what was it?
Even now I can but guess — brain in part as we understand brain, certainly; but far, far more than that in its energies, its powers.
It was like an immense rose. An incredible rose of a thousand close clustering petals. It blossomed with a myriad shifting hues. And instant by instant the flood of varicolored flame that poured into its petalings down from the sapphire ovoids waxed and waned in crescendoes and diminuendoes of relucent harmonies — ecstatic, awesome.
The heart of the rose was a star of incandescent ruby.
From the flaming crimson center to aureate, flashing penumbra it was instinct with and poured forth power — power vast and conscious.
Not with that same completeness could I realize the ministering star shapes, half hidden as they were by the Disk. Their radiance was less, nor had they its miracle of pulsing gem fires. Blue they were, blue of a peculiar vibrancy, and blue were the glistening threads that ran down from blue-black circular convexities set within each of the points visible to me.
Unlike in shape, their flame of vitality dimmer than the ovoids of the Disk’s golden zone, still I knew that they were even as those — ORGANS, organs of unknown senses, unknown potentialities. Their nuclei I could not observe.
The floating figures had drawn close to that disk and had paused.
And on the moment of their pausing I felt a surge of strength, a snapping of the spell that had bound us, an instantaneous withdrawal of the inhibiting force. Ventnor broke into a run, holding his rifle at the alert. We raced after him; were close to the shining shapes. And, gasping, we stopped short not a dozen paces away.
For Norhala had soared up toward the flaming rose of the Disk as though lifted by gentle, unseen hands. Close to it for an instant she swung. I saw the exquisite body gleam through her thin robes as though bathed in soft flames of rosy pearl.
Higher she floated, and toward the right of the zodiac. From the edges of three of the ovoids swirled a little cloud of tentacles, gossamer filaments of opal. They whipped out a full yard from the Disk’s surface, touching her, caressing her.
For a moment she hung there, her face hidden from us; then was dropped softly to her feet and stood, arms stretched wide, her copper hair streaming cloudily about her regal head.
And up past her floated Ruth, levitated as had been she — and her face,
