The Illustrated Complete Works of H.P. Lovecraft

offending minds in their new future bodies—and sometimes forced re-exchanges were effected. Complex cases of the displacement of exploring or already captive minds by minds in various regions of the past had been known and carefully rectified. In every age since the discovery of mind-projection, a minute but well-recognised element of the population consisted of Great Race minds from past ages, sojourning for a longer or shorter while.
    When a captive mind of alien origin was returned to its own body in the future, it was purged by an intricate mechanical hypnosis of all it had learned in the Great Race’s age—this because of certain troublesome consequences inherent in the general carrying forward of knowledge in large quantities. The few existing instances of clear transmission had caused, and would cause at known future times, great disasters. And it was largely in consequence of two cases of the kind (said the old myths) that mankind had learned what it had concerning the Great Race. Of all things surviving physically and directly from that aeon-distant world, there remained only certain ruins of great stones in far places and under the sea, and parts of the text of the frightful Pnakotic Manuscripts.
    Thus the returning mind reached its own age with only the faintest and most fragmentary visions of what it had undergone since its seizure. All memories that could be eradicated were eradicated, so that in most cases only a dream-shadowed blank stretched back to the time of the first exchange. Some minds recalled more than others, and the chance joining of memories had at rare times brought hints of the forbidden past to future ages. There probably never was a time when groups or cults did not secretly cherish certain of these hints. In the Necronomicon the presence of such a cult among human beings was suggested—a cult that sometimes gave aid to minds voyaging down the aeons from the days of the Great Race.
    And meanwhile the Great Race itself waxed well-nigh omniscient, and turned to the task of setting up exchanges with the minds of other planets, and of exploring their pasts and futures. It sought likewise to fathom the past years and origin of that black, aeon-dead orb in far space whence its own mental heritage had come—for the mind of the Great Race was older than its bodily form. The beings of a dying elder world, wise with the ultimate secrets, had looked ahead for a new world and species wherein they might have long life; and had sent their minds en masse into that future race best adapted to house them—the cone-shaped things that peopled our earth a billion years ago. Thus the Great Race came to be, while the myriad minds sent backward were left to die in the horror of strange shapes. Later the race would again face death, yet would live through another forward migration of its best minds into the bodies of others who had a longer physical span ahead of them.
    Such was the background of intertwined legend and hallucination. When, around 1920, I had my researches in coherent shape, I felt a slight lessening of the tension which their earlier stages had increased. After all, and in spite of the fancies prompted by blind emotions, were not most of my phenomena readily explainable? Any chance might have turned my mind to dark studies during the amnesia—and then I read the forbidden legends and met the members of ancient and ill-regarded cults. That, plainly, supplied the material for the dreams and disturbed feelings which came after the return of memory. As for the marginal notes in dream-hieroglyphs and languages unknown to me, but laid at my door by librarians—I might easily have picked up a smattering of the tongues during my secondary state, while the hieroglyphs were doubtless coined by my fancy from descriptions in old legends, and afterward woven into my dreams. I tried to verify certain points through conversation with known cult-leaders, but never succeeded in establishing the right connexions.
    At times the parallelism of so many cases in so many distant ages continued to worry me as it had at first, but on the other hand I reflected that the excitant folklore was undoubtedly more universal in the past than in the present. Probably all the other victims whose cases were like mine had had a long and familiar knowledge of the tales I had learned only when in my secondary state. When these victims had lost their memory, they had associated themselves with the creatures of their
