'' they worshipped so they said the great old ones who lived ages before there where any man, and who came to the young world out of the sky. those old ones were gone now, inside the earth and under the sea ... mankind was not absolutely alone among the conscious things of earth, for shapes came out of the dark to visit the faithful few. but these were not the great old ones. no man had ever seen the old ones. ...

'' there had been aeons when other things ruled on the earth, ... they all died vast epochs of time before man came,but there were arts which could revive them when the stars come round again to the right positions in the cycle of eternity ... when the stars were right, they could plunge from world to world through the sky; but when the stars were wrong, they could not live. but although they no longer lived, they would never really die. they all lay in stone houses in their great city of r'lyeh, preserved by the spells of mighty cthulhu for a glorious resurrection when the stars and the earth might once more be ready for them. ...

'' in the elder time chosen men had talked with the entombed old ones in dreams, but had then something had happened. the great stone city r'leyeh, with its monoliths and sepulchres, had sunk beneath the waves; and 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 high-priests said that the city would rise again when the stars were right.
