With an effort, however, Willett pulled himself together and began studying the formulae chiseled on the walls. From the stained and incrusted letters it was obvious that they were carved in Joseph Curwen’s time, and their text was such as to be vaguely familiar to one who had read much Curwen material or delved extensively into the history of magic. One the doctor clearly recognized as what Mrs. Ward heard her son chanting on that ominous Good Friday a year before, and what an authority had told him was a very terrible invocation addressed to secret gods outside the normal spheres. It was not spelled here exactly as Mrs. Ward had set it down from memory, nor yet as the authority had shown it to him in the forbidden pages of “Eliphas Levi”; but its identity was unmistakable, and such words as Sabaoth, Metraton, Almonsin, and Zariatnatmik sent a shudder of fright through the searcher who had seen and felt so much of cosmic abomination just around the corner.
This was on the left-hand wall as one entered the room. The right-hand wall was no less thickly inscribed, and Willett felt a start of recognition as he came upon the pair of formulae so frequently occurring in the recent notes in the library. They were, roughly speaking, the same; with the ancient symbols of “Dragon’s Head” and “Dragon’s Tail” heading them as in Ward’s scribblings. But the spelling differed quite widely from that of the modern versions, as if old Curwen had had a different way of recording sound, or as if later study had evolved more powerful and perfected variants of the invocations in question. The doctor tried to reconcile the chiseled version with the one which still ran persistently in his head, and found it hard to do. Where the script he had memorized began “Y’ai ’Ng’ngah, Yog-Sothoth,” this epigraph started out as “Aye, cngengah, Yogge-Sothotha”; which to his mind would seriously interfere with the syllabification of the second word.
Ground as the later text was into his consciousness, the discrepancy disturbed him; and he found himself chanting the first of the formulae aloud in an effort to square the sound he conceived with the letters he found carved. Weird and menacing in that abyss of antique blasphemy rang his voice! its accents keyed to a droning singsong either through the spell of the past and the unknown, or through the hellish example of that dull, godless wail from the pits whose inhuman cadences rose and fell rhythmically in the distance through the stench and darkness.
“Yʻai ʻNgʻngah
Yog-Sothoth

Fʻaiʻ Throdog
Uaah!
But what was this cold wind which had sprung into life at the very outset of the chant? The lamps were sputtering woefully, and the gloom grew so dense that the letters on the wall nearly faded from sight. There was smoke, too, and an acrid odor which quite drowned out the stench from the faraway wells; an odor like that he had smelt before, yet infinitely stronger and more pungent. He turned from the inscriptions to face the room with its bizarre contents, and saw that the kylix on the floor, in which the ominous efflorescent powder had lain, was giving forth a cloud of thick, greenish-black vapor of surprising volume and opacity. That powder—Great God! it had come from the shelf of “Custodes”—what was it doing now, and what had started it? The formula he had been chanting—the first of the pair—Dragon’s Head, ascending node—Blessed Saviour, could it be—
The doctor reeled, and through his head raced wildly disjointed scraps from all he had seen, heard, and read of the frightful case of Joseph Curwen and Charles Dexter Ward. “I say to you againe, doe not call up Any that you cannot put downe. … Have ye Wordes for laying at all times readie, and stopp not to be sure when there is any Doubte of Whom you have—Three Talkes
