Wilbur had with him the priceless but imperfect copy of Dr Dee's English version which his grandfather had bequeathed him, and upon receiving access to the Latin copy he at once began to collate the two texts with the aim of discovering a certain passage which would have come on the 751st page of his own defective volume. This much he could not civilly refrain from telling the librarian—the same erudite Henry Armitage (A.M. Miskatonic, Ph.D. Princeton, Litt.D. Johns Hopkins) who had once called at the farm, and who now politely plied him with questions. He was looking, he had to admit, for a kind of formula or incantation containing the frightful name Yog-Sothoth, and it puzzled him to find discrepancies, duplications, and ambiguities which made the matter of determination far from easy. As he copied the formula he finally chose, Dr Armitage looked involuntarily over his shoulder at the open pages; the left-hand one of which, in the Latin version, contained such monstrous threats to the peace and sanity of the world.
Nor is it to be thought (ran the text as Armitage mentally translated it) that man is either the oldest or the last of earth's masters, or that the common bulk of life and substance walks alone. The Old Ones were, the Old Ones are, and the Old Ones shall be. Not in the spaces we know, but between them, they walk serene and primal, undimensioned and to us unseen. Yog-Sothoth knows the gate. Yog-Sothoth is the gate. Yog-Sothoth is the key and guardian of the gate. Past, present, future, all are one in Yog-Sothoth. He knows where the Old Ones broke through of old, and where They shall break through again. He knows where They had trod earth's fields, and where They still tread them, and why no one can behold Them as They tread. By Their smell can men sometimes know Them near, but of Their semblance can no man know, saving only in the features of those They have begotten on mankind; and of those are there many sorts, differing in likeness from man's truest eidolon to that shape without sight or substance which is Them. They walk unseen and foul in lonely places where the Words have been spoken and the Rites howled through at their Seasons. The wind gibbers with Their voices, and the earth mutters with Their consciousness. They bend the forest and crush the city, yet may not forest or city behold the hand that smites. Kadath in the cold waste hath known Them, and what man knows Kadath? The ice desert of the South and the sunken isles of Ocean hold stones whereon Their seal is engraved, but who hath seen the deep frozen city or the sealed tower long garlanded with seaweed and barnacles? Great Cthulhu is Their cousin, yet can he spy Them only dimly. Iä! Shub-Niggurath! As a foulness shall ye know Them. Their hand is at your throats, yet ye see Them not; and Their habitation is even one with your guarded threshold. Yog-Sothoth is the key to the gate, whereby the spheres meet. Man rules now where They ruled once; They shall soon rule where man rules now. After summer is winter, after winter summer. They wait patient and potent, for here shall They reign again.Dr. Armitage, associating what he was reading with what he had heard of Dunwich and its brooding presences, and of Wilbur Whateley and his dim, hideous aura that stretched from a dubious birth to a cloud of probable matricide, felt a wave of fright as tangible as a draught of the tomb's cold clamminess. The bent, goatish giant before him seemed like the spawn of another planet or dimension; like something only partly of mankind, and linked to black gulfs of essence and entity that stretch like titan phantasms beyond all spheres of force and matter, space and time. Presently Wilbur raised his head and began speaking in that strange, resonant fashion which hinted at sound-producing organs unlike the run of mankind's.
'Mr Armitage,' he said, 'I calc'late I've got to take that book home. They's things in it I've got to try under sarten conditions that I can't git here, en' it 'ud be a mortal sin to let a red-tape rule hold me up. Let me take it along, Sir, an' I'll swar they wun't nobody know the difference. I dun't need to tell ye I'll take good keer of it. It wan't me that put this Dee copy in the shape it is...'
He stopped as he saw firm denial on the librarian's face, and his own goatish features grew crafty. Armitage, half-ready to tell him he might make a copy of what parts he needed, thought suddenly of the possible consequences and checked himself. There was too much responsibility in giving such a being the key to such blasphemous outer spheres. Whateley saw how things stood, and tried to answer lightly.
'Wal, all right, ef ye feel that way abaout it. Maybe Harvard won't be so fussy as yew be.' And without saying more he rose and strode out of the building, stooping at each doorway.
Armitage heard the savage yelping of the great watchdog, and studied Whateley's gorilla-like lope as he crossed the bit of campus visible from the window. He thought of the wild tales he had heard, and recalled the old Sunday stories in the Advertiser; these things, and the lore he had picked up from Dunwich rustics and villagers during his one visit there. Unseen things not of earth—or at least not of tridimensional earth—rushed foetid and horrible through New England's glens, and brooded obscenely on the mountain tops. Of this he had long felt certain. Now he seemed to sense the close presence of some terrible part of the intruding horror, and to glimpse a hellish advance in the black dominion of the ancient and once passive nightmare. He locked away the Necronomicon with a shudder of disgust, but the room still reeked with an unholy and unidentifiable stench. 'As a foulness shall ye know them,' he quoted. Yes—the odour was the same as that which had sickened him at the Whateley farmhouse less than three years before. He thought of Wilbur, goatish and ominous, once again, and laughed mockingly at the village rumours of his parentage.
'Inbreeding?' Armitage muttered half-aloud to himself. 'Great God, what simpletons! Show them Arthur Machen's Great God Pan and they'll think it a common Dunwich scandal! But what thing—what cursed shapeless influence on or off this three-dimensional earth—was Wilbur Whateley's father? Born on Candlemas—nine months after May Eve of 1912, when the talk about the queer earth noises reached clear to Arkham—what walked on the mountains that May night? What Roodmas horror fastened itself on the world in half-human flesh and blood?'
During the ensuing weeks Dr Armitage set about to collect all possible data on Wilbur Whateley and the formless presences around Dunwich. He got in communication with Dr Houghton of Aylesbury, who had attended Old Whateley in his last illness, and found much to ponder over in the grandfather's last words as quoted by the physician. A visit to Dunwich Village failed to bring out much that was new; but a close survey of the Necronomicon, in those parts which Wilbur had sought so avidly, seemed to supply new and terrible clues to the nature, methods, and desires of the strange evil so vaguely threatening this planet. Talks with several students of archaic lore in Boston, and letters to many others elsewhere, gave him a growing amazement which passed slowly through varied degrees of alarm to a state of really acute spiritual fear. As the summer drew on he felt dimly that something ought to be done about the lurking terrors of the upper Miskatonic valley, and about the monstrous being known to the human world as Wilbur Whateley.
"The Dunwich Horror" is a tale by H. P. Lovecraft. Written in 1928, it was first published in the April 1929 issue of Weird Tales (pp. 481-508).
