I am writing this under an appreciable mental strain, since by tonight I shall be no more. - H. P. Lovecraft

In youth he had felt the hidden beauty and ecstasy of things, and had been a poet; but poverty and sorrow and exile had turned his gaze in darker directions, and he had thrilled at the imputations of evil in the world around. Daily life had for him come to be a phantasmagoria of macabre shadow-studies; now glittering and leering with concealed rottenness as in Beardsley's best manner, now hinting terrors behind the commonest shapes and objects as in the subtler and less obvious work of Gustave Dore. He would often regard it as merciful that most persons of high Intelligence jeer at the inmost mysteries; for, he argued, if superior minds were ever placed in fullest contact with the secrets preserved by ancient and lowly cults, the resultant abnormalities would soon not only wreck the world, but threaten the very integrity of the universe. All this reflection was no doubt morbid, but keen logic and a deep sense of humour ably offset it. Malone was satisfied to let his notions remain as half-spied and forbidden visions to be lightly played with; and hysteria came only when duty flung him into a hell of revelation too sudden and insidious to escape.

What, in substance, both the Esquimaux wizards and the Louisiana swamp-priests had chanted to their kindred idols was something very like this: the word-divisions being guessed at from traditional breaks in the phrase as chanted aloud: "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn." ... "In his house at R'lyeh dead Cthulhu waits dreaming." .

I could not help feeling that they were evil things — mountains of madness whose farther slopes looked out over some accursed ultimate abyss. That seething , half-luminous cloud-background held ineffable suggestions of a vague, ethereal beyondness far more than terrestrially spatial; and gave appalling reminders of the utter remoteness, separateness, desolation, and aeon-long death of this untrodden and unfathomed austral world.
