In the elder time chosen men had talked with the entombed Old Ones in dreams, but then something happened. The great stone city R'lyeh, with its monoliths and sepulchres, had sunk beneath the waves; and the deep waters, full of the one primal mystery through which not even thought can pass, had cut off the spectral intercourse. But memory never died, and the high-priests said that the city would rise again when the stars were right. Then came out of the earth the black spirits of earth, moldy and shadowy, and full of dim rumors picked up in caverns beneath forgotten sea-bottoms. But of them old Castro dared not speak much. He cut himself off hurriedly, and no amount of persuasion or subtlety could elicit more in this direction. The size of the Old Ones, too, he curiously declined to mention. Of the cult, he said that he thought the center lay amid the pathless desert of Arabia, where Irem, the City of Pillars, dreams hidden and untouched. It was not allied to the European witch-cult, and was virtually unknown beyond its members. No book had ever really hinted of it, though the deathless Chinamen said that there were double meanings in the Necronomicon of the mad Arab Abdul Alhazred which the initiated might read as they chose, especially the much-discussed couplet: That is not dead which can eternal lie, And with strange aeons even death may die.
