Without surprise, he found that he was gazing simultaneously in two directions. On either hand, for a vast distance that was wholly void of normal perspective, a weird and peculiar landscape stretched away, traversed by an unbroken frieze or bas-relief of human figures that ran like a straight undeviating wall.

For awhile, the frieze was incomprehensible to Balcoth, he could make nothing of its glacial, flowing outlines with their background of repeated masses and complicated angles and sections of other human friezes that approached or departed, often in a very abrupt manner, from an unseen world beyond. Then the vision seemed to resolve and clarify itself, and he began to understand.

The bas-relief, he saw, was composed entirely of a repetition of his own figure, plainly distinct as the separate waves of a stream, and possessing a stream-like unity. Immediately before him, and for some distance on either hand, the figure was seated in a chair—the chair itself being subject to the same billowy repetition. The background was composed of the reduplicated figure of Dr. Manners, in another chair; and behind this, the manifold images of a medicine cabinet and a section of wall-panelling.

Following the vista on what, for lack of any better name, might be termed the left hand, Balcoth saw himself in the act of draining the antique glass, with Manners standing before him. Then, still further, he saw himself previous to this, with a background in which Manners was presenting him the glass, was preparing the dose of plutonium, was going to the cabinet for the vial, was rising from his pneumatic chair. Every movement, every attitude of the doctor and himself during their past conversation, was visioned in a sort of reverse order, reaching away, unalterable as a wall of stone sculpture, into the weird, eternal landscape. There was no break in the continuity of his own figure; but Manners seemed to disappear at times, as if into a fourth dimension. These times, he remembered later, were the occasions when the doctor had not been in his line of vision. The perception was wholly visual; and though Balcoth saw his own lips and those of Manners parted in the frozen movements of speech, he could hear no word or other sound.

Perhaps the most singular feature of the vision was the utter absence of foreshortening. Though Balcoth seemed to behold it all from a fixed, immovable point, the landscape and the intersecting frieze presented themselves to him without diminution, maintaining a frontal fullness and distinctness to a distance that might have been many miles.

Continuing along the left-hand vista, he saw himself entering Manners’ apartments, and then encountered his image standing in the elevator that had borne him to the ninth floor of the hundred story hotel in which Manners lived. Then the frieze appeared to have an open street for background, with a confused, ever-changing multitude of other faces and forms, of vehicles and sections of buildings, all jumbled together as in some old-time futuristic painting. Some of these details were full and clear, and others were cryptically broken and blurred, so as to be scarcely recognizable. Everything, whatever its spatial position and relation, was re-arranged in the flowing frozen stream of this temporal pattern.

Balcoth retraced the three blocks from Manners’ hotel to his own studio, seeing all his past movements, whatever their direction in tri-dimensional space, as a straight line in the time-dimension. At last he was in his studio; and there the frieze of his own figure receded into the eerie prospect of space-transmuted time among other friezes formed of actual sculptures. He beheld himself giving the final touches with his chisel to a symbolic statue at the afternoon’s end, with a glare of ruddy sunset falling through an unseen window and flushing the pallid marble. Beyond, there was a reverse fading of the glow, a thickening and blurring of the half-chiselled features of the image, a female form to which he had given the tentative name of Oblivion. At length, among half-seen statuary, the left-hand vista became indistinct, and melted slowly in amorphous mist. He had seen his own life as a continuous glaciated stream, stretching for about five hours into the past.

Reaching away on the right hand, he saw the vista of the future. Here there was a continuation of his seated figure under the influence of the drug, opposite the continued bas-relief of Dr. Manners and the repeated cabinet and wall-panels. After a considerable interval, he beheld himself in the act of rising from the chair. Standing erect, he seemed to be talking awhile, as in some silent antique film, to the listening doctor. After that, he was shaking hands with Manners, was leaving the apartment, was descending in the lift and following the open, brightly-litten street toward the Belvedere Club where he was to keep his appointment with Claud Wishhaven.

The Club was only three blocks away, on another street; and the shortest route, after the first block, was along a narrow alley between an office building and a warehouse. Balcoth had meant to take this alley; and in his vision, he saw the bas-relief of his future figure passing along the straight pavement with a background of deserted doorways and dim walls that towered from sight against the extinguished stars.

He seemed to be alone: there were no passers—only the silent, glimmering endlessly repeated angles of arc-lit walls and windows that accompanied his repeated figure. He saw himself following the alley, like a stream in some profound canyon; and there midway, the strange vision came to an abrupt inexplicable end, without the gradual blurring into formless mist, that had marked his retrospective view of the past.

The sculpture-like frieze with its architectural ground appeared to terminate, broken off clean and sharp, in a gulf of immeasurable blackness and nullity. The last wave-like duplication of his own person, the vague doorway beyond it, the glimmering alley-pavement, all were seen as if shorn asunder by a falling sword of darkness, leaving a vertical line of cleavage beyond which there was—nothing.

Balcoth had a feeling of utter detachment from himself, an eloignment from the stream of time, from the shores of space, in some abstract dimension. The experience, in its full realization, might have lasted for an instant only—or for eternity. Without wonder, without curiosity or reflection, like a fourth-dimensional Eye, he viewed simultaneously the unequal cross-sections of his own past and future.

After that timeless interval of complete perception, there began a reverse process of change. He, the all-seeing Eye, aloof in super-space, was aware of movement, as if he were drawn back by some subtle thread of magnetism into the dungeon of time and space from which he had momentarily departed. He seemed to be following the frieze of his own seated body toward the right, with a dimly felt rhythm or pulsation in his movement that corresponded to the merging duplications of the figure. With curious clearness, he realized that the time-unit by which these duplications were determined, was the beating of his own heart.

Now with accelerative swiftness, the vision of petrific form and space was re-dissolving into a spiral swirl of multitudinous colors, through which he was drawn upward. Presently he came to himself, seated in the pneumatic chair, with Dr. Manners opposite. The room seemed to waver a little, as if with some lingering touch of the weird transmutation; and webs of spinning iris hung in the corners of his eyes. Apart from this, the effect of the drug had wholly vanished, leaving, however, a singularly clear and vivid memory of the almost ineffable experience.

Dr. Manners began to question him at once, and Balcoth described his visionary sensations as fully and graphically as he could.

“There is one thing I don’t understand,” said Manners at the end with a puzzled frown. “According to your account, you must have seen five or six hours of the past, running in a straight spatial line, as a sort of continuous landscape; but the vista of the future ended sharply after you had followed it for three-quarters of an hour; or less. I’ve never known the drug to act so unequally: the past and future perspectives have always been about the same in their extent for others who have used plutonium.”
