April 22
This has been a day of horrible discovery. I explored the cobwebbed attic again, and found a carved, crumbling chest — plainly from Holland — full of blasphemous books and papers far older than any hitherto encountered here. There was a Greek Necronomicon, a Norman-French Livre d’Eibon, and a first edition of old Ludvig Prinn’s De Vermis Mysteriis. But the old bound manuscript was the worst. It was in low Latin, and full of the strange, crabbed handwriting of Claes van der Heyl — being evidently the diary or notebook kept by him between 1560 and 1580. When I unfastened the blackened silver clasp and opened the yellowed leaves a coloured drawing fluttered out — the likeness of a monstrous creature resembling nothing so much as a squid, beaked and tentacled, with great yellow eyes, and with certain abominable approximations to the human form in its contours.
I had never before seen so utterly loathsome and nightmarish a form. On the paws, feet, and head-tentacles were curious claws — reminding me of the colossal shadow-shapes which have groped so horribly in my path — while the entity as a whole sat upon a great throne-like pedestal inscribed with unknown hieroglyphs of vaguely Chinese cast. About both writing and image there hung an air of sinister evil so profound and pervasive that I could not think it the product of any one world or age. Rather must that monstrous shape be a focus for all the evil in unbounded space, throughout the aeons past and to come — and those eldritch symbols be vile sentient eikons endowed with a morbid life of their own and ready to wrest themselves from the parchment for the reader’s destruction. To the meaning of that monster and of those hieroglyphs I had no clue, but I knew that both had been traced with a hellish precision and for no namable purpose. As I studied the leering characters, their kinship to the symbols on that ominous lock in the cellar became more and more manifest. I left the picture in the attic, for never could sleep come to me with such a thing nearby.
All the afternoon and evening I read in the manuscript book of old Claes van der Heyl, and what I read will cloud and make horrible whatever period of life lies ahead of me. The genesis of the world, and of previous worlds, unfolded itself before my eyes. I learned of the city Shamballah, built by the Lemurians fifty million years ago, yet inviolate still behind its walls of psychic force in the eastern desert. I learned of the Book of Dzyan, whose first six chapters antedate the earth, and which was old when the lords of Venus came through space in their ships to civilise our planet. And I saw recorded in writing for the first time that name which others had spoken to me in whispers, and which I had known in a closer and more horrible way — the shunned and dreaded name of Yian-Ho.
In several places I was held up by passages requiring a key. Eventually, from various allusions, I gathered that old Claes had not dared to embody all his knowledge in one book, but had left certain points for another. Neither volume can be wholly intelligible without its fellow; hence I have resolved to find the second one if it lies anywhere within this accursed house. Though plainly a prisoner, I have not lost my lifelong zeal for the unknown; and am determined to probe the cosmos as deeply as possible before doom comes.
April 23
Searched all the morning for the second diary, and found it about noon in a desk in the little locked room. Like the first, it is in Claes van der Heyl’s barbarous Latin; and it seems to consist of disjointed notes referring to various sections of the other. Glancing through the leaves, I spied at once the abhorred name of Yian-Ho — of Yian-Ho, that lost and hidden city wherein brood aeon-old secrets, and of which dim memories older than the body lurk behind the minds of all men. It was repeated many times, and the text around it was strown with crudely drawn hieroglyphs plainly akin to those on the pedestal in that hellish drawing I had seen. Here, clearly, lay the key to that monstrous tentacled shape and its forbidden message. With this knowledge I ascended the creaking stairs to the attic of cobwebs and horror.
When I tried to open the attic door it stuck as never before. Several times it resisted every effort to open it, and when at last it gave way I had a distinct feeling that some colossal, unseen shape had suddenly released it — a shape that soared away on non-material but audibly beating wings. When I found the horrible drawing I felt that it was not precisely where I had left it. Applying the key in the other book, I soon saw that the latter was no instant guide to the secret. It was only a clue — a clue to a secret too black to be left lightly guarded. It would take hours — perhaps days — to extract the awful message.
Shall I live long enough to learn the secret? The shadowy black arms and paws haunt my vision more and more now, and seem even more titanic than at first. Nor am I ever long free from those vague, unhuman presences whose nebulous bulk seems too vast for the chambers to contain. And now and then the grotesque, evanescent faces and forms, and the mocking portrait-shapes, troop before me in bewildering confusion.
