When Gilman stood up, the tiles felt hot to his bare feet. He was wholly alone, and his first act was to walk to the balustrade and look dizzily down at the endless, Cyclopean city almost two thousand feet below. As he listened he thought a rhythmic confusion of faint musical pipings covering a wide tonal range welled up from the narrow streets beneath, and he wished he might discern the denizens of the place. The sight turned him giddy after a while, so that he would have fallen to the pavement had he not clutched instinctively at the lustrous balustrade. His right hand fell on one of the projecting figures, the touch seeming to steady him slightly. It was too much, however, for the exotic delicacy of the metal-work, and the spiky figure snapped off under his grasp. Still half dazed, he continued to clutch it as his other hand seized a vacant space on the smooth railing.

But now his over-sensitive ears caught something behind him, and he looked back across the level terrace. Approaching him softly though without apparent furtiveness were five figures, two of which were the sinister old woman and the fanged, furry little animal. The other three were what sent him unconscious; for they were living entities about eight feet high, shaped precisely like the spiky images on the balustrade, and propelling themselves by a spider-like wriggling of their lower set of starfish-arms.

Gilman awoke in his bed, drenched by a cold perspiration and with a smarting sensation in his face, hands and feet. Springing to the floor, he washed and dressed in frantic haste, as if it were necessary for him to get out of the house as quickly as possible. He did not know where he wished to go, but felt that once more he would have to sacrifice his classes. The odd pull toward that spot in the sky between Hydra and Argo had abated, but another of even greater strength had taken its place. Now he felt that he must go north–infinitely north. He dreaded to cross the bridge that gave a view of the desolate island in the Miskatonic, so went over the Peabody Avenue bridge. Very often he stumbled, for his eyes and ears were chained to an extremely lofty point in the blank blue sky.

After about an hour he got himself under better control, and saw that he was far from the city. All around him stretched the bleak emptiness of salt marshes, while the narrow road ahead led to Innsmouth–that ancient, half-deserted town which Arkham people were so curiously unwilling to visit. Though the northward pull had not diminished, he resisted it as he had resisted the other pull, and finally found that he could almost balance the one against the other. Plodding back to town and getting some coffee at a soda fountain, he dragged himself into the public library and browsed aimlessly among the lighter magazines. Once he met some friends who remarked how oddly sunburned he looked, but he did not tell them of his walk. At three o’clock he took some lunch at a restaurant, noting meanwhile that the pull had either lessened or divided itself. After that he killed the time at a cheap cinema show, seeing the inane performance over and over again without paying any attention to it.

About nine at night he drifted homeward and shuffled into the ancient house. Joe Mazurewicz was whining unintelligible prayers, and Gilman hastened up to his own garret chamber without pausing to see if Elwood was in. It was when he turned on the feeble electric light that the shock came. At once he saw there was something on the table which did not belong there, and a second look left no room for doubt. Lying on its side–for it could not stand up alone–was the exotic spiky figure which in his monstrous dream he had broken off the fantastic balustrade. No detail was missing. The ridged, barrel-shaped center, the thin radiating arms, the knobs at each end, and the flat, slightly outward-curving starfish-arms spreading from those knobs–all were there. In the electric light the colour seemed to be a kind of iridescent grey veined with green; and Gilman could see amidst his horror and bewilderment that one of the knobs ended in a jagged break, corresponding to its former point of attachment to the dream-railing.

Only his tendency toward a dazed stupor prevented him from screaming aloud. This fusion of dream and reality was too much to bear. Still dazed, he clutched at the spiky thing and staggered downstairs to Landlord Dombrowski’s quarters. The whining prayers of the superstitious loom-fixer were still sounding through the mouldy halls, but Gilman did not mind them now. The landlord was in, and greeted him pleasantly. No, he had not seen that thing before and did not know anything about it. But his wife had said she found a funny tin thing in one of the beds when she fixed the rooms at noon, and maybe that was it. Dombrowski called her, and she waddled in. Yes, that was the thing. She had found it in the young gentleman’s bed–on the side next the wall. It had looked very queer to her, but of course the young gentleman had lots of queer things in his room–books and curios and pictures and markings on paper. She certainly knew nothing about it.

So Gilman climbed upstairs again in mental turmoil, convinced that he was either still dreaming or that his somnambulism had run to incredible extremes and led him to depredations in unknown places. Where had he got this outré thing? He did not recall seeing it in any museum in Arkham. It must have been somewhere, though; and the sight of it as he snatched it in his sleep must have caused the odd dream-picture of the balustraded terrace. Next day he would make some very guarded inquiries–and perhaps see the nerve specialist.

Mazurewicz was waiting for him at the door, and seemed both anxious and reluctant to whisper some fresh bit of superstition. It was about the witch-light. Joe had been out celebrating the night before–and it was Patriots’ Day in Massachusetts–and had come home after midnight. Looking up at the house from outside, he had thought at first that Gilman’s window was dark, but then he had seen the faint violet glow within. He wanted to warn the gentleman about that glow, for everybody in Arkham knew it was Keziah’s witch-light which played near Brown Jenkin and the ghost of the old crone herself. He had not mentioned this before, but now he must tell about it because it meant that Keziah and her long-toothed familiar were haunting the young gentleman. Sometimes he and Paul Choynski and Landlord Dombrowski thought they saw that light seeping out of cracks in the sealed loft above the young gentleman’s room, but they had all agreed not to talk about that. However, it would be better for the gentleman to take another room and get a crucifix from some good priest like Father Iwanicki.

As the man rambled on, Gilman felt a nameless panic clutch at his throat. He knew that Joe must have been half drunk when he came home the night before; yet the mention of a violet light in the garret window was of frightful import. It was a lambent glow of this sort which always played about the old woman and the small furry thing in those lighter, sharper dreams which prefaced his plunge into unknown abysses, and the thought that a wakeful second person could see the dream-luminance was utterly beyond sane harborage. Yet where had the fellow got such an odd notion? Had he himself talked as well as walked around the house in his sleep? No, Joe said, he had not–but he must check up on this. Perhaps Frank Elwood could tell him something, though he hated to ask.

Fever–wild dreams–somnambulism–illusions of sounds–a pull toward a point in the sky–and now a suspicion of insane sleep-talking! He must stop studying, see a nerve specialist, and take himself in hand. When he climbed to the second storey he paused at Elwood’s door but saw that the other youth was out. Reluctantly he continued up to his garret room and sat down in the dark. His gaze was still pulled to the southward, but he also found himself listening intently for some sound in the closed loft above, and half imagining that an evil violet light seeped down through an infinitesimal crack in the low, slanting ceiling.

That night as Gilman slept, the violet light broke upon him with heightened intensity, and the old witch and small furry thing, getting closer than ever before, mocked him with inhuman squeals and devilish gestures. He was glad to sink into the vaguely roaring twilight abysses, though the pursuit of that iridescent bubble-congeries and that kaleidoscopic little polyhedron was menacing and irritating. Then came the shift as vast converging planes of a slippery-looking substance loomed above and below him–a shift which ended in a flash of delirium and a blaze of unknown, alien light in which yellow, carmine, and indigo were madly and inextricably blended.

He was half lying on a high, fantastically balustraded terrace above a boundless jungle of outlandish, incredible peaks, balanced planes, domes, minarets, horizontal disks poised on pinnacles, and numberless forms of still greater wildness–some of stone and some of metal–which glittered gorgeously in the mixed, almost blistering glare from a poly-chromatic sky. Looking upward he saw three stupendous disks of flame, each of a different hue, and at a different height above an infinitely distant curving horizon of low mountains. Behind him tiers of higher terraces towered aloft as far as he could see. The city below stretched away to the limits of vision, and he hoped that no sound would well up from it.

The pavement from which he easily raised himself was a veined polished stone beyond his power to identify, and the tiles were cut in bizarre-angled shapes which struck him as less asymmetrical than based on some unearthly symmetry whose laws he could not comprehend. The balustrade was chest-high, delicate, and fantastically wrought, while along the rail were ranged at short intervals little figures of grotesque design and exquisite workmanship. They, like the whole balustrade, seemed to be made of some sort of shining metal whose colour could not be guessed in the chaos of mixed effulgences, and their nature utterly defied conjecture. They represented some ridged barrel-shaped objects with thin horizontal arms radiating spoke-like from a central ring and with vertical knobs or bulbs projecting from the head and base of the barrel. Each of these knobs was the hub of a system of five long, flat, triangularly tapering arms arranged around it like the arms of a starfish–nearly horizontal, but curving slightly away from the central barrel. The base of the bottom knob was fused to the long railing with so delicate a point of contact that several figures had been broken off and were missing. The figures were about four and a half inches in height, while the spiky arms gave them a maximum diameter of about two and a half inches.

When Gilman stood up, the tiles felt hot to his bare feet. He was wholly alone, and his first act was to walk to the balustrade and look dizzily down at the endless, Cyclopean city almost two thousand feet below. As he listened he thought a rhythmic confusion of faint musical pipings covering a wide tonal range welled up from the narrow streets beneath, and he wished he might discern the denizens of the place. The sight turned him giddy after a while, so that he would have fallen to the pavement had he not clutched instinctively at the lustrous balustrade. His right hand fell on one of the projecting figures, the touch seeming to steady him slightly. It was too much, however, for the exotic delicacy of the metal-work, and the spiky figure snapped off under his grasp. Still half dazed, he continued to clutch it as his other hand seized a vacant space on the smooth railing.

Then he saw the two shapes laboriously crawling toward him–the old woman and the little furry thing. The crone strained up to her knees and managed to cross her arms in a singular fashion, while Brown Jenkin pointed in a certain direction with a horribly anthropoid forepaw which it raised with evident difficulty. Spurred by an impulse he did not originate, Gilman dragged himself forward along a course determined by the angle of the old woman’s arms and the direction of the small monstrosity’s paw, and before he had shuffled three steps he was back in the twilight abysses. Geometrical shapes seethed around him, and he fell dizzily and interminably. At last he woke in his bed in the crazily angled garret of the eldritch old house.

He was good for nothing that morning, and stayed away from all his classes. Some unknown attraction was pulling his eyes in a seemingly irrelevant direction, for he could not help staring at a certain vacant spot on the floor. As the day advanced, the focus of his unseeing eyes changed position, and by noon he had conquered the impulse to stare at vacancy. About two o’clock he went out for lunch and as he threaded the narrow lanes of the city he found himself turning always to the southeast. Only an effort halted him at a cafeteria in Church Street, and after the meal he felt the unknown pull still more strongly.

He would have to consult a nerve specialist after all–perhaps there was a connection with his somnambulism–but meanwhile he might at least try to break the morbid spell himself. Undoubtedly he could still manage to walk away from the pull, so with great resolution he headed against it and dragged himself deliberately north along Garrison Street. By the time he had reached the bridge over the Miskatonic he was in a cold perspiration, and he clutched at the iron railing as he gazed upstream at the ill-regarded island whose regular lines of ancient standing stones brooded sullenly in the afternoon sunlight.

Then he gave a start. For there was a clearly visible living figure on that desolate island, and a second glance told him it was certainly the strange old woman whose sinister aspect had worked itself so disastrously into his dreams. The tall grass near her was moving, too, as if some other living thing were crawling close to the ground. When the old woman began to turn toward him he fled precipitately off the bridge and into the shelter of the town’s labyrinthine waterfront alleys. Distant though the island was, he felt that a monstrous and invincible evil could flow from the sardonic stare of that bent, ancient figure in brown.

The southeastwards pull still held, and only with tremendous resolution could Gilman drag himself into the old house and up the rickety stairs. For hours he sat silent and aimless, with his eyes shifting gradually westward. About six o’clock his sharpened ears caught the whining prayers of Joe Mazurewicz two floors below, and in desperation he seized his hat and walked out into the sunset-golden streets, letting the now directly southward pull carry him where it might. An hour later darkness found him in the open fields beyond Hangman’s Brook, with the glimmering spring stars shining ahead. The urge to walk was gradually changing to an urge to leap mystically into space, and suddenly he realized just where the source of the pull lay.

It was in the sky. A definite point among the stars had a claim on him and was calling him. Apparently it was a point somewhere between Hydra and Argo Navis, and he knew that he had been urged toward it ever since he had awaked soon after dawn. In the morning it had been underfoot, and now it was roughly south but stealing toward the west. What was the meaning of this new thing? Was he going mad? How long would it last? Again mustering his resolution, Gilman turned and dragged himself back to the sinister old house.

Mazurewicz was waiting for him at the door, and seemed both anxious and reluctant to whisper some fresh bit of superstition. It was about the witch-light. Joe had been out celebrating the night before–and it was Patriots’ Day in Massachusetts–and had come home after midnight. Looking up at the house from outside, he had thought at first that Gilman’s window was dark, but then he had seen the faint violet glow within. He wanted to warn the gentleman about that glow, for everybody in Arkham knew it was Keziah’s witch-light which played near Brown Jenkin and the ghost of the old crone herself. He had not mentioned this before, but now he must tell about it because it meant that Keziah and her long-toothed familiar were haunting the young gentleman. Sometimes he and Paul Choynski and Landlord Dombrowski thought they saw that light seeping out of cracks in the sealed loft above the young gentleman’s room, but they had all agreed not to talk about that. However, it would be better for the gentleman to take another room and get a crucifix from some good priest like Father Iwanicki.

Gilman dropped in at the doctor’s office on the sixteenth of the month, and was surprised to find his temperature was not as high as he had feared. The physician questioned him sharply, and advised him to see a nerve specialist. On reflection, he was glad he had not consulted the still more inquisitive college doctor. Old Waldron, who had curtailed his activities before, would have made him take a rest–an impossible thing now that he was so close to great results in his equations. He was certainly near the boundary between the known universe and the fourth dimension, and who could say how much farther he might go?

But even as these thoughts came to him he wondered at the source of his strange confidence. Did all of this perilous sense of immininence come from the formulae on the sheets he covered day by day? The soft, stealthy, imaginary footsteps in the sealed loft above were unnerving. And now, too, there was a growing feeling that somebody was constantly persuading him to do something terrible which he could not do. How about the somnambulism? Where did he go sometimes in the night? And what was that faint suggestion of sound which once in a while seemed to trickle through the confusion of identifiable sounds even in broad daylight and full wakefulness? Its rhythm did not correspond to anything on earth, unless perhaps to the cadence of one or two unmentionable Sabbat-chants, and sometimes he feared it corresponded to certain attributes of the vague shrieking or roaring in those wholly alien abysses of dream.

The dreams were meanwhile getting to be atrocious. In the lighter preliminary phase the evil old woman was now of fiendish distinctness, and Gilman knew she was the one who had frightened him in the slums. Her bent back, long nose, and shrivelled chin were unmistakable, and her shapeless brown garments were like those he remembered. The expression on her face was one of hideous malevolence and exultation, and when he awaked he could recall a croaking voice that persuaded and threatened. He must meet the Black Man and go with them all to the throne of Azathoth at the centre of ultimate chaos. That was what she said. He must sign the book of Azathoth in his own blood and take a new secret name now that his independent delvings had gone so far. What kept him from going with her and Brown Jenkin and the other to the throne of Chaos where the thin flutes pipe mindlessly was the fact that he had seen the name “Azathoth” in the Necronomicon, and knew it stood for a primal evil too horrible for description.

The old woman always appeared out of thin air near the corner where the downward slant met the inward slant. She seemed to crystallize at a point closer to the ceiling than to the floor, and every night she was a little nearer and more distinct before the dream shifted. Brown Jenkin, too was always a little nearer at the last, and its yellowish-white fangs glistened shockingly in that unearthly violet phosphorescence. Its shrill loathsome tittering struck more and more into Gilman’s head, and he could remember in the morning how it had pronounced the words “Azathoth” and “Nyarlathotep.”

In the deeper dreams everything was likewise more distinct, and Gilman felt that the twilight abysses around him were those of the fourth dimension. Those organic entities whose motions seemed least flagrantly irrelevant and unmotivated were probably projections of life-forms from our own planet, including human beings. What the others were in their own dimensional sphere or spheres he dared not try to think. Two of the less irrelevantly moving things–a rather large congeries of iridescent, prolately spheroidal bubbles and a very much smaller polyhedron of unknown colours and rapidly shifting surface angles–seemed to take notice of him and follow him about or float ahead as he changed position among the titan prisms, labyrinths, cube-and-plane clusters and quasi-buildings; and all the while the vague shrieking and roaring waxed louder and louder, as if approaching some monstrous climax of utterly unendurable intensity.

During the night of 19-20 April the new development occurred. Gilman was half involuntarily moving about in the twilight abysses with the bubble-mass and the small polyhedron floating ahead when he noticed the peculiarly regular angles formed by the edges of some gigantic neighbouring prism-clusters. In another second he was out of the abyss and standing tremulously on a rocky hillside bathed in intense, diffused green light. He was barefooted and in his nightclothes. and when he tried to walk discovered that he could scarcely lift his feet. A swirling vapour hid everything but the immediate sloping terrain from sight, and he shrank from the thought of the sounds, that might surge out of that vapour.

Then he saw the two shapes laboriously crawling toward him–the old woman and the little furry thing. The crone strained up to her knees and managed to cross her arms in a singular fashion, while Brown Jenkin pointed in a certain direction with a horribly anthropoid forepaw which it raised with evident difficulty. Spurred by an impulse he did not originate, Gilman dragged himself forward along a course determined by the angle of the old woman’s arms and the direction of the small monstrosity’s paw, and before he had shuffled three steps he was back in the twilight abysses. Geometrical shapes seethed around him, and he fell dizzily and interminably. At last he woke in his bed in the crazily angled garret of the eldritch old house.

Toward the end of March he began to pick up in his mathematics, though the other studies bothered him increasingly. He was getting an intuitive knack for solving Riemannian equations, and astonished Professor Upham by his comprehension of fourth-dimensional and other problems which had floored all the rest of the class. One afternoon there was a discussion of possible freakish curvatures in space, and of theoretical points of approach or even contact between our part of the cosmos and various other regions as distant as the farthest stars or the transgalactic gulfs themselves–or even as fabulously remote as the tentatively conceivable cosmic units beyond the whole Einsteinian space-time continuum. Gilman’s handling of this theme filled everyone with admiration, even though some of his hypothetical illustrations caused an increase in the always plentiful gossip about his nervous and solitary eccentricity. What made the students shake their heads was his sober theory that a man might–given mathematical knowledge admittedly beyond all likelihood of human acquirement–step deliberately from the earth to any other celestial body which might lie at one of an infinity of specific points in the cosmic pattern.

Such a step, he said, would require only two stages; first, a passage out of the three-dimensional sphere we know, and second, a passage back to the three-dimensional sphere at another point, perhaps one of infinite remoteness. That this could be accomplished without loss of life was in many cases conceivable. Any being from any part of three-dimensional space could probably survive in the fourth dimension; and its survival of the second stage would depend upon what alien part of three-dimensional space it might select for its re-entry. Denizens of some planets might be able to live on certain others–even planets belonging to other galaxies, or to similar dimensional phases of other space-time continua–though of course there must be vast numbers of mutually uninhabitable even though mathematically juxtaposed bodies or zones of space.

It was also possible that the inhabitants of a given dimensional realm could survive entry to many unknown and incomprehensible realms of additional or indefinitely multiplied dimensions–be they within or outside the given space-time continuum–and that the converse would be likewise true. This was a matter for speculation, though one could be fairly certain that the type of mutation involved in a passage from any given dimensional plane to the next higher one would not be destructive of biological integrity as we understand it. Gilman could not be very clear about his reasons for this last assumption, but his haziness here was more than overbalanced by his clearness on other complex points. Professor Upham especially liked his demonstration of the kinship of higher mathematics to certain phases of magical lore transmitted down the ages from an ineffable antiquity–human or pre-human–whose knowledge of the cosmos and its laws was greater than ours.

Around 1 April Gilman worried considerably because his slow fever did not abate. He was also troubled by what some of his fellow lodgers said about his sleep-walking. It seemed that he was often absent from his bed and that the creaking of his floor at certain hours of the night was remarked by the man in the room below. This fellow also spoke of hearing the tread of shod feet in the night; but Gilman was sure he must have been mistaken in this, since shoes as well as other apparel were always precisely in place in the morning. One could develop all sorts of aural delusions in this morbid old house–for did not Gilman himself, even in daylight, now feel certain that noises other than rat-scratching came from the black voids beyond the slanting wall and above the slanting ceiling? His pathologically sensitive ears began to listen for faint footfalls in the immemorially sealed loft overhead, and sometimes the illusion of such things was agonizingly realistic.

However, he knew that he had actually become a somnambulist; for twice at night his room had been found vacant, though with all his clothing in place. Of this he had been assured by Frank Elwood, the one fellow-student whose poverty forced him to room in this squalid and unpopular house. Elwood had been studying in the small hours and had come up for help on a differential equation, only to find Gilman absent. It had been rather presumptuous of him to open the unlocked door after knocking had failed to rouse a response, but he had needed the help very badly and thought that his host would not mind a gentle prodding awake. On neither occasion, though, had Gilman been there; and when told of the matter he wondered where he could have been wandering, barefoot and with only his night clothes on. He resolved to investigate the matter if reports of his sleep-walking continued, and thought of sprinkling flour on the floor of the corridor to see where his footsteps might lead. The door was the only conceivable egress, for there was no possible foothold outside the narrow window.

As April advanced, Gilman’s fever-sharpened ears were disturbed by the whining prayers of a superstitious loom-fixer named Joe Mazurewicz who had a room on the ground floor. Mazurewicz had told long, rambling stories about the ghost of old Keziah and the furry sharp-fanged, nuzzling thing, and had said he was so badly haunted at times that only his silver crucifix–given him for the purpose by Father Iwanicki of St. Stanislaus’ Church–could bring him relief. Now he was praying because the Witches’ Sabbath was drawing near. May Eve was Walpurgis Night, when hell’s blackest evil roamed the earth and all the slaves of Satan gathered for nameless rites and deeds. It was always a very bad time in Arkham, even though the fine folks up in Miskatonic Avenue and High and Saltonstall Streets pretended to know nothing about it. There would be bad doings, and a child or two would probably be missing. Joe knew about such things, for his grandmother in the old country had heard tales from her grandmother. It was wise to pray and count one’s beads at this season. For three months Keziah and Brown Jenkin had not been near Joe’s room, nor near Paul Choynski’s room, nor anywhere else–and it meant no good when they held off like that. They must be up to something.

Gilman dropped in at the doctor’s office on the sixteenth of the month, and was surprised to find his temperature was not as high as he had feared. The physician questioned him sharply, and advised him to see a nerve specialist. On reflection, he was glad he had not consulted the still more inquisitive college doctor. Old Waldron, who had curtailed his activities before, would have made him take a rest–an impossible thing now that he was so close to great results in his equations. He was certainly near the boundary between the known universe and the fourth dimension, and who could say how much farther he might go?
