In H. P. Lovecraft's 1936 novella "The Shadow Out of Time," the protagonist Nathaniel Peaslee has his body stolen temporarily by a time-traveling mind belonging to one of the Great Race. During the five years that the intruder uses Peaslee's body to study early twentieth-century Earth, Peaslee himself lives on in his captor's original body, one hundred fifty million years in the past.
Recounting the memories that he recovers of his strange imprisonment, Peaslee describes many other displaced minds that he meets. He first lists a number of non-human captives, who are in a similar situation to his own.
There was a mind from the planet we know as Venus, which would live incalculable epochs to come, and one from an outer moon of Jupiter six million years in the past. Of earthly minds there were some from the winged, star-headed, half-vegetable race of palaeogean Antarctica; one from the reptile people of fabled Valusia; three from the furry pre-human Hyperborean worshippers of Tsathoggua; one from the wholly abominable Tcho-Tchos; two from the arachnid denizens of earth’s last age; five from the hardy coleopterous species immediately following mankind, to which the Great Race was some day to transfer its keenest minds en masse in the face of horrible peril; and several from different branches of humanity.
Many of the entities mentioned come from other tales written by Lovecraft and his correspondents, the first generation of contributors to the Cthulhu Mythos. The aliens from Venus and the moon of Jupiter are not sufficiently described to make them recognizable. However, the list does clearly include:
- "the winged, star-headed, half-vegetable race"—from Lovecraft's At the Mountains of Madness
- "reptile people of fabled Valusia"—from the first King Kull story by Robert E. Howard, "The Shadow Kingdom"
- "furry pre-human Hyperborean worshippers of Tsathoggua"—from the Hyperborea stories by Clarke Ashton Smith, especially "The Seven Geases"
- "abominable Tcho-Tchos"—from "The Lair of the Star Spawn" by August Derleth and Mark Schorer (found in Weird Tales, August 1932)
However, the last two I do not recognize as coming from other sources:
- "the arachnid denizens of earth’s last age"
- "the hardy coleopterous species immediately following mankind"
There are also a few more races mentioned later in the narrative:
- "bulbous vegetable entities of Mercury" [in the far future, after Earth is too cold to be inhabitable]
- "a half-plastic denizen of the hollow interior of an unknown trans-Plutonian planet eighteen million years in the future"
The race of intelligent beetles (or "coleoptera") may well be original to this story, since they play a more prominent role in the long-term fate of the Great Race than any of the other types mentioned. However, they might previously have been written about elsewhere, and so might the arachnids and others. So, were these one-off creations that Lovecraft threw into the story, or did any of them originate is previous Cthulhu Mythos works?
The next paragraph after the one quoted above lists a number of specific human minds that Peaslee meets among the captives of the Great Race. A number of them come from recognizable historical periods (e.g. a twelfth-century Florentine monk, a quaestor in Sulla’s time), but there are several fantastical ones as well.
I talked with the mind of Yiang-Li, a philosopher from the cruel empire of Tsan-Chan, which is to come in A.D. 5000; with that of a general of the great-headed brown people who held South Africa in B.C. 50,000;... with that of a king of Lomar who had ruled that terrible polar land 100,000 years before the squat, yellow Inutos came from the west to engulf it; with that of Nug-Soth, a magician of the dark conquerors of A.D. 16,000;... with that of Crom-Ya, a Cimmerian chieftain of B.C. 15,000; and with so many others that my brain cannot hold the shocking secrets and dizzying marvels I learned from them.
Among these, two are clear allusions to other works:
- Crom-Ya (based on both the name and the date) is a reference to Howard's Cimmerians (Conan's people).
- Lomar (and its conquest by the Inutos) was introduced in Lovecraft's "Polaris," and the author referenced the kingdom a number of times in later tales.
However, the others I find illusive. All the unidentified proper names ("Yiang-Li," "Tsan-Chan," and "Nug-Soth") appear to have been reused by later writers, themselves homaging Lovecraft. However is not inconceivable that Lovecraft may have intended some of the civilizations he mentions as homages themselves:
- "the cruel empire of Tsan-Chan"
- "great-headed brown people who held South Africa in B.C. 50,000"
- "the dark conquerors of A.D. 16,000"
Are any of these peoples references to other authors or works?
