For Ubbo-Sathla is the source and the end. Before the coming of Zhothaqquah or Yok-Zothoth or Kthulhut from the stars, Ubbo-Sathla dwelt in the steaming fens of the newmade Earth: a mass without head or members, spawning the grey, formless efts of the prime and the grisly prototypes of terrene life . . . And all earthly life, it is told, shall go back at last through the great circle of time to Ubbo-Sathla.
     —The Book of Eibon.

Paul Tregardis found the milky crystal in a litter of oddments from many lands and eras. He had entered the shop of the curio-dealer through an aimless impulse, with no particular object in mind, other than the idle distraction of eyeing and fingering a miscellany of far-gathered things. Looking desultorily about, his attention had been drawn by a dull glimmering on one of the tables; and he had extricated the queer orb-like stone from its shadowy, crowded position between an ugly little Aztec idol, the fossil egg of a dinornis, and an obscene fetich of black wood from the Niger.

The thing was about the size of a small orange and was slightly flattened at the ends, like a planet at its poles. It puzzled Tregardis, for it was not like an ordinary crystal, being cloudy and changeable, with an intermittent glowing in its heart, as if it were alternately illumed and darkened from within. Holding it to the wintry window, he studied it for awhile without being able to determine the secret of this singular and regular alternation. His puzzlement was soon complicated by a dawning sense of vague and irrecognizable familiarity, as if he had seen the thing before under circumstances that were now wholly forgotten.

He appealed to the curio-dealer, a dwarfish Hebrew with an air of dusty antiquity, who gave the impression of being lost to commercial considerations in some web of cabbalistic revery.

"Can you tell me anything about this?"

The dealer gave an indescribable, simultaneous shrug of his shoulders and his eye-brows.

"It is very old—palaeogean, one might say. I cannot tell you much, for little is known. A geologist found it in Greenland, beneath glacial ice, in the Miocene strata. Who knows? It may have belonged to some sorcerer of primeval Thule. Greenland was a warm, fertile region, beneath the sun of Miocene times. No doubt it is a magic crystal; and a man might behold strange visions in its heart, if he looked long enough."

Tregardis was quite startled; for the dealer's apparently fantastic suggestion had brought to mind his own delvings in a branch of obscure lore; and, in particular, had recalled The Book of Eibon, that strangest and rarest of occult forgotten volumes, which is said to have come down through a series of manifold translations from a prehistoric original written in the lost language of Hyperborea. Tregardis, with much difficulty, had obtained the medieval French version—a copy that had been owned by many generations of sorcerers and Satanists—but had never been able to find the Greek manuscript from which the version was derived.

The remote, fabulous original was supposed to have been the work of a great Hyperborean wizard, from whom it had taken its name. It was a collection of dark and baleful myths, of liturgies, rituals and incantations both evil and esoteric. Not without shudders, in the course of studies that the average person would have considered more than singular, Tregardis had collated the French volume with the frightful Necronomicon of the mad Arab, Abdul Alhazred. He had found many correspondences of the blackest and most appalling significance, together with much forbidden data that was either unknown to the Arab or omitted by him ... or by his translators.

Was this what he had been trying to recall, Tregardis wondered? —the brief, casual reference, in The Book of Eibon, to a cloudy crystal that had been owned by the wizard Zon Mezzamalech, in Mhu Thulan? Of course, it was all too fantastic, too hypothetic, too incredible—but Mhu Thulan, that northern portion of ancient Hyperborea, was supposed to have corresponded roughly with Modem Greenland, which had formerly been joined as a peninsula to the main continent. Could the stone in his hand, by some fabulous fortuity, be the crystal of Zon Mezzamalech?

Tregardis smiled at himself with inward irony for even conceiving the absurd notion. Such things did not occur—at least, not in present-day London; and in all likelihood, The Book of Eibon was sheer superstitious fantasy, anyway. Nevertheless, there was something about the crystal that continued to tease and inveigle him. He ended by purchasing it, at a fairly moderate price. The sum was named by the seller and paid by the buyer without bargaining.

With the crystal in his pocket, Paul Tregardis hastened back to his lodgings instead of resuming his leisurely saunter. He installed the milky globe on his writing table, where it stood firmly enough on one of its oblate ends. Then, still smiling at his own absurdity, he took down the yellow parchment manuscript of The Book of Eibon from its place in a somewhat inclusive collection of recherché literature. He opened the vermiculated leather cover with hasps of tarnished steel, and read over to himself, translating from the archaic French as he read, the paragraph that referred to Zon Mezzamalech:

"This wizard, who was mighty among sorcerers, had found a cloudy stone, orb-like and somewhat flattened at the ends, in which he could behold many visions of the terrene past, even to the Earth's beginning, when Ubbo-Sathla, the unbegotten source, lay vast and swollen and yeasty amid the vaporing slime . . . But of that which he beheld, Zon Mezzamalech left little record; and people say that he vanished presently, in a way that is not known; and after him the cloudy crystal was lost."

Paul Tregardis laid the manuscript aside. Again there was something that tantalized and beguiled him, like a lost dream or a memory forfeit to oblivion. Impelled by a feeling which he did not scrutinize or question, he sat down before the table and began to stare intently into the cold, nebulous orb. He felt an expectation which, somehow, was so familiar, so permeative a part of his consciousness, that he did not even name it to himself.

Minute by minute he sat, and watched the alternate glimmering and fading of the mysterious light in the heart of the crystal. By imperceptible degrees, there stole upon him a sense of dreamlike duality, both in respect to his person and his surroundings. He was still Paul Tregardis—and yet he was someone else; the room was his London apartment—and a chamber in some foreign but well-known place. And in both milieus he peered steadfastly into the same crystal.

After an interim, without surprise on the part of Tregardis, the process of re-identification became complete. He knew that he was Zon Mezzamalech, a sorcerer of Mhu Thulan, and a student of all lore anterior to his own epoch. Wise with dreadful secrets that were not known to Paul Tregardis, amateur of anthropology and the occult sciences in latter-day London, he sought by means of the milky crystal to attain an even older and more fearful knowledge.

He had acquired the stone in dubitable ways, from a more than sinister source. It was unique and without fellow in any land or time. In its depths, all former years, all things that have ever been, were supposedly mirrored, and would reveal themselves to the patient visionary. And through the crystal, Zon Mezzamalech had dreamt to recover the wisdom of the gods who died before the Earth was born. They had passed to the lightless void, leaving their lore inscribed upon tablets of ultra-stellar stone; and the tablets were guarded in the primal mire by the formless, idiotic demiurge, Ubbo-Sathla. Only by means of the crystal could he hope to find and read the tablets.

For the first time, he was making trial of the globe's reputed virtues. About him an ivory-panelled chamber, filled with his magic books and paraphernalia, was fading slowly from his consciousness. Before him, on a table of some dark Hyperborean wood that had been graven with grotesque ciphers, the crystal appeared to swell and deepen, and in its filmy depth he beheld a swift and broken swirling of dim scenes, fleeting like the bubbles of a millrace. As if he looked upon an actual world, cities, forests, mountains, seas and meadows flowed beneath him, lightening and darkening as with the passage of days and nights in some weirdly accelerated stream of time.

Zon Mezzamalech had forgotten Paul Tregardis—had lost the remembrance of his own entity and his own surroundings in Mhu Thulan. Moment by moment, the flowing vision in the crystal became more definite and distinct, and the orb itself deepened till he grew giddy, as if he were peering from an insecure height into some never-fathomed abyss. He knew that time was racing backward in the crystal, was unrolling for him the pageant of all past days; but a strange alarm had seized him, and he feared to gaze longer. Like one who has nearly fallen from a precipice, he caught himself with a violent start and drew back from the mystic orb.

Again, to his gaze, the enormous whirling world into which he had peered was a small and cloudy crystal on his rune-wrought table in Mhu Thulan. Then, by degrees, it seemed that the great room with sculptured panels of mammoth ivory was narrowing to another and dingier place; and Zon Mezzamalech, losing his preternatural wisdom and sorcerous power, went back by a weird regression into Paul Tregardis.

And yet not wholly, it seemed, was he able to return. Tregardis, dazed and wondering, found himself before the writing table on which he had set the oblate sphere. He felt the confusion of one who has dreamt and has not yet fully awakened from the dream. The room puzzled him vaguely, as if something were wrong with its size and furnishings; and his remembrance of purchasing the crystal from a curio-dealer was oddly and discrepantly mingled with an impression that he had acquired it in a very different manner.

He felt that something very strange had happened to him when he peered into the crystal; but just what it was he could not seem to recollect. It had left him in the sort of psychic muddlement that follows a debauch of hashish. He assured himself that he was Paul Tregardis, that he lived on a certain street in London, that the year was 1932; but such common-place verities had somehow lost their meaning and their validity; and everything about him was shadow-like and insubstantial. The very walls seemed to waver like smoke; the people in the streets were phantoms of phantoms; and he himself was a lost shadow, a wandering echo of something long forgot.

He resolved that he would not repeat his experiment of crystal-gazing. The effects were too unpleasant and equivocal. But the very next day, by an unreasoning impulse to which he yielded almost mechanically, without reluctation, he found himself seated before the misty orb. Again he became the sorcerer Zon Mezzamalech in Mhu Thulan; again he dreamt to retrieve the wisdom of the antemundane gods; again he drew back from the deepening crystal with the terror of one who fears to fall; and once more—but doubtfully and dimly, like a failing wraith—he was Paul Tregardis.

Three times did Tregardis repeat the experience on successive days; and each time his own person and the world about him became more tenuous and confused than before. His sensations were those of a dreamer who is on the verge of waking; and London itself was unreal as the lands that slip from the dreamer's ken, receding in filmy mist and cloudy light. Beyond it all, he felt the looming and crowding of vast imageries, alien but half-familiar. It was as if the phantasmagoria of time and space were dissolving about him, to reveal some veritable reality—or another dream of space and time.

There came, at last, the day when he sat down before the crystal—and did not return as Paul Tregardis. It was the day when Zon Mezzamalech, boldly disregarding certain evil and portentous warnings, resolved to overcome his curious fear of failing bodily into the visionary world that he beheld—a fear that had hitherto prevented him from following the backward stream of time for any distance. He must, he assured himself, conquer this fear if he were ever to see and read the lost tablets of the gods. He had beheld nothing more than a few fragments of the years of Mhu Thulan immediately posterior to the present-the years of his own life-time; and there were inestimable cycles between these years and the Beginning.

Again, to his gaze, the crystal deepened immeasurably, with scenes and happenings that flowed in a retrograde stream. Again the magic ciphers of the dark table faded from his ken, and the sorcerously carven walls of his chamber melted into less than dream. Once more he grew giddy with an awful vertigo as he bent above the swirling and milling of the terrible gulfs of time in the worldlike orb. Fearfully, in spite of his resolution, he would have drawn away; but he had looked and leaned too long. There was a sense of abysmal falling, a suction as of ineluctable winds, of maelstroms that bore him down through fleet unstable visions of his own past life into antenatal years and dimensions. He seemed to endure the pangs of an inverse dissolution; and then he was no longer Zon Mezzamalech, the wise and learned watcher of the crystal, but an actual part of the weirdly racing stream that ran back to re-attain the Beginning.

He seemed to live unnumbered lives, to die myriad deaths, forgetting each time the death and life that had gone before. He fought as a warrior in half-legendary battles; he was a child playing in the ruins of some olden city of Mhu Thulan; he was the king who had reigned when the city was in its prime, the prophet who had foretold its building and its doom. A woman, he wept for the bygone dead in necropoli long-crumbled; an antique wizard, he muttered the rude spells of earlier sorcery; a priest of some pre-human god, he wielded the sacrificial knife in cave-temples of pillared basalt. Life by life, era by era, he re-traced the long and groping cycles through which Hyperborea had risen from savagery to a high civilization.

He became a barbarian of some troglodytic tribe, fleeing from the slow, turreted ice of a former glacial age into lands illumed by the ruddy flare of perpetual volcanoes. Then, after incomputable years, he was no longer man, but a man-like beast, roving in forests of giant fern and calamite, or building an uncouth nest in the boughs of mighty cycads.

Through aeons of anterior sensation, of crude lust and hunger, of aboriginal terror and madness, there was someone—or something—that went ever backward in time. Death became birth, and birth was death. In a slow vision of reverse change, the earth appeared to melt away, and sloughed off the hills and mountains of its latter strata. Always the sun grew larger and hotter above the fuming swamps that teemed with a crasser life, with a more fulsome vegetation. And the thing that had been Paul Tregardis, that had been Zon Mezzamalech, was a part of all the monstrous devolution. It flew with the claw-tipped wings of a pterodactyl, it swam in tepid seas with the vast, winding bulk of an ichthyosaurus, it bellowed uncouthly with the armored throat of some forgotten behemoth to the huge moon that burned through primordial mists.

At length, after aeons of immemorial brutehood, it became one of the lost serpent-men who reared their cities of black gneiss and fought their venomous wars in the world's first continent. It walked undulously in ante-human streets, in strange crooked vaults; it peered at primeval stars from high, Babelian towers; it bowed with hissing litanies to great serpent-idols. Through years and ages of the ophidian era it returned, and was a thing that crawled in the ooze, that had not yet learned to think and dream and build. And the time came when there was no longer a continent, but only a vast, chaotic marsh, a sea of slime, without limit or horizon, without shore or elevation, that seethed with a blind writhing of amorphous vapors.

There, in the grey beginning of Earth, the formless mass that was Ubbo-Sathla reposed amid the slime and the vapors. Headless, without organs or members, it sloughed from its oozy sides, in a slow, ceaseless wave, the amoebic forms that were the archetypes of earthly life. Horrible it was, if there had been aught to apprehend the horror; and loathsome, if there had been any to feel loathing. About it, prone or tilted in the mire, there lay the mighty tablets of star-quarried stone that were writ with the inconceivable wisdom of the pre-mundane gods.

And there, to the goal of a forgotten search, was drawn the thing that had been—or would sometime be—Paul Tregardis and Zon Mezzamalech. Becoming a shapeless eft of the prime, it crawled sluggishly and obliviously across the fallen tablets of the gods, and fought and ravened blindly with the other spawn of Ubbo-Sathla.

Of Zon Mezzamalech and his vanishing, there is no mention anywhere, save the brief passage in The Book of Eibon. Concerning Paul Tregardis, who also disappeared, there was a curt notice in several of the London papers. No one seems to have known anything about him: he is gone as if he had never been; and the crystal, presumably, is gone too. At least, no one has found it.
