The tidy history of science fiction runs from Frankenstein to rockets and robots, but a second, stranger current runs alongside it, carrying lost continents, hollow earths, and visitors from the stars, the same “damned data” Charles Fort spent his life collecting. This is the story of how that buried lineage ran from Kepler’s dream through Lovecraft’s cosmic horrors into a pulp magazine that put a lost continent on its cover in the exact month Kenneth Arnold saw his flying saucers.
The Hidden Lineage of Science Fiction and the Unexplained
In June 1947, American newsstands carried a special issue of a science-fiction magazine given over entirely to a single startling claim: that a race of corrupted beings survived in caverns deep beneath our feet, the last remnants of a lost civilisation, tormenting the surface world with rays no instrument could detect. The magazine was Amazing Stories. Its readers wrote in by the thousand to say they had felt those rays, or met those beings. And in the same month that this underground myth reached its peak, a pilot named Kenneth Arnold looked out of his cockpit over the Cascade Mountains, saw nine bright objects skimming the ridgelines, and handed the modern world its first flying saucers.
No one planned that timing, and no one needed to. The same current was running through both, and the editor who published the underground myth would spend the rest of his career promoting the objects in the sky. To understand how a lost-continent fantasy and a national-security mystery arrived in the same summer, you have to go back a very long way, because both are branches of one tree. That tree is science fiction, and its roots reach down into exactly the material that official science spent three centuries trying to bury.
The two origin stories of science fiction
There is a tidy account of where science fiction comes from, and it is taught more or less everywhere. It runs from Mary Shelley to Jules Verne to H. G. Wells to the pulp magazines of the 1920s, and it presents the genre as the literature of progress: rockets, robots, time machines, the future arriving on schedule. In that telling, science fiction is the fiction of reason, the imaginative wing of the Enlightenment, forever facing forward.
That version is true as far as it goes. It also leaves out half the story. Alongside the fiction of progress, and tangled all the way through it, runs a darker and older current: a fascination with the things reason could not file. Lost continents. Hollow Earth. Visitors from the stars. Forces the instruments could not measure, and the textbooks would not admit. The same genre that dreamed of the future was also the place where the discarded past and the unexplained present went to be imagined out loud. Charles Fort spent thirty years collecting the raw material of that second current, the reports science had recorded and set aside. Science fiction is, in large part, what happened when writers picked that material up and gave it a plot.
The respectable ancestors, and the shadow inside them
The genre’s official family tree is old and distinguished, and the shadow is already inside it. In the second century, the Greek satirist Lucian of Samosata wrote a voyage to the Moon and back, complete with wars between the peoples of the Sun and the Moon, and framed the whole thing as a send-up of the tall tales told by travellers and by philosophers who claimed to know things no one could know. Fourteen centuries later, the astronomer Johannes Kepler wrote Somnium, a journey to the Moon grounded in real astronomy and narrated by a spirit summoned in a dream. That detail was not harmless. Kepler’s own mother was tried as a witch, and the dream’s spirit-summoning frame, with its herb-wise mother-figure, sat uncomfortably close to the accusations she faced. The first work of properly scientific fiction and a witchcraft trial came out of the same household, which tells you how thin the wall between science and the forbidden really was.
Margaret Cavendish sent a heroine through the North Pole into another world in 1666. But the figure everyone returns to is Mary Shelley, who in 1818 gave the genre its first undeniable masterpiece. Frankenstein is usually praised for abandoning the ghosts and curses of the Gothic novel in favour of galvanism and laboratory plausibility. What is easy to forget is that it was written as a ghost story, dreamed up during a wet summer on Lake Geneva when Lord Byron challenged his guests to frighten one another. The founding novel of the literature of reason was born in a competition to raise the dead.
The line from there is familiar. Edgar Allan Poe, whom the pulps would later claim as a founder, wrote meticulous scientific hoaxes designed to fool newspaper readers into believing a man had crossed the Atlantic by balloon, blurring fact and fiction on purpose. Jules Verne, who admired Poe, sent his explorers down through a volcano into a lit and living world at the centre of the Earth. H. G. Wells imagined a Martian invasion that regarded humanity as insects to be cleared away, a cosmic demotion that would echo through everything after it. And in 1926, a Luxembourg-born inventor named Hugo Gernsback gathered Poe, Verne and Wells under one banner in a new magazine called Amazing Stories, coined a word for what they had in common, and gave the genre its name: Science Fiction. Hold on to that magazine. It circles back later.
Fort, the archivist of the damned
Every current needs a source, and the modern one has a name. For the better part of three decades, Charles Fort sat in the reading rooms of the New York Public Library and the British Museum and copied out, by hand, the reports that science had recorded and then quietly declined to explain. Falls of frogs and stones and red rain. Lights and objects in the sky. People who vanished and things that appeared from nowhere. He called this material the damned, the data excluded from the acceptable because no theory could hold it, and he gathered tens of thousands of notes and built them into four strange, funny, deliberately maddening books.
Fort was no believer. He offered his wilder hypotheses, a Super-Sargasso Sea of lost objects drifting overhead, an Earth quietly owned by something that regarded us as its property, with a shrug and a grin, precisely to show that they fit the reported facts about as well as the respectable answers did. What he could not forgive was the reflex to throw the report away before anyone had examined it. He kept the excluded data on the table and refused to close the case in either direction. In doing so, he assembled, almost single-handedly, the reference library of the strange, and writers came to browse it. When they did, the shadow current of science fiction found its roots.
Lovecraft, the mythmaker of the forgotten
The greatest of those browsers was Howard Phillips Lovecraft. Working out of Providence, Rhode Island, in the 1920s and 1930s, Lovecraft built something the genre had not seen before: a mythology of cosmic indifference, in which humanity is a recent accident on an insignificant planet, watched or ignored by vast alien intelligences older than the solar system, and in which knowledge itself becomes the danger, because to grasp our true place is to lose one’s mind. He called the emotion he was chasing cosmic fear, and it has shaped horror and science fiction ever since.
His debt to Fort was enormous and credited, and at one point he named it directly on the page. In “The Whisperer in Darkness,” published in Weird Tales in 1931, a folklore dispute breaks out over strange bodies glimpsed in flooded Vermont rivers, and a few of the wilder voices invoke “the extravagant books of Charles Fort” to argue that the hidden things had come from other worlds. The horror of the tale is that the cranks are right. The strange bodies are the Mi-Go, a fungoid extraterrestrial race quietly mining the Vermont hills for a mineral they cannot obtain at home, and so indifferent to us that they will lift a living man’s brain out of his skull and carry it across space in a metal cylinder once he has learned too much. That is Fort’s grimmest joke, the idea that we are property, turned into myth and given teeth.

And Lovecraft kept going underground. His horrors are forever buried: a nameless city swallowed by the desert sand, an ancient civilisation entombed beneath the Antarctic ice in At the Mountains of Madness, older intelligences sleeping under the soil and the sea. The pattern is always the same. The Earth is older, and stranger than the textbooks allow; something enormous preceded us and may still be here, and the record of it lies just beneath the surface, waiting for the wrong person to dig it up. It is Fort’s damned data rendered as dread, and it would turn out to be astonishingly close to what the culture was about to do for real.
The bloodline beneath our feet
The idea that something lived below was older than Lovecraft and older than Fort, and it carried its own respectable and disreputable lineage. In 1818, the same year Frankenstein appeared, an American army officer named John Cleves Symmes announced that the Earth was hollow and open at the poles, and that a lost inner world might be reached by sailing into the gaps. He was mocked, yet he was also taken seriously enough that polar expeditions were proposed in his name. Verne sent his explorers down in 1864. And in 1871, the English novelist and politician Edward Bulwer-Lytton published The Coming Race, in which a traveller descends into a mine and discovers a subterranean master race, the Vril-ya, who command a limitless energy force they call Vril.
Vril did not stay on the page. It escaped into the occult underground and became a genuine object of belief, feeding esoteric movements and, later, some of the darkest mythologies of the twentieth century, a thread followed elsewhere on Lightnet in UFOs, Vril and Nazi Secrets: A Hidden History of Alien Technology. A fiction had hardened into a faith, which is the exact border this whole story keeps crossing.
The other great tributary was Theosophy. From the 1880s, Helena Blavatsky taught of vanished continents and lost root races, of an Atlantis and a Lemuria peopled by earlier humanities, and her sweeping esoteric history sank deep into the popular imagination. The occult currents that flowed from her, and the uses to which they were later put, are traced on Lightnet in The Alchemists of the Abyss: Blavatsky, Thule and the Nazi Occult Timeline. What matters here is the name she gave her lost southern continent. She called it Lemuria, and a few decades later a pulp magazine would put that word on its cover and set the modern age of the unexplained alight.
1947, where the fiction became a phenomenon
In 1943, the editor of Amazing Stories, originally founded by Gernsback, received a letter from a Pennsylvania factory worker named Richard Shaver. Shaver said he could hear voices, and that they rose from beneath the Earth, from the corrupted survivors of an ancient race he called the Deros, who lived in enormous caverns and afflicted humanity with hidden rays. An assistant editor threw the letter in the bin. The editor, Ray Palmer, fished it out and decided to print it.
Palmer reworked what Shaver had sent into a story called “I Remember Lemuria!” and ran it in March 1945, and he did the one thing the genre had never quite dared. He presented it as true. The response was enormous. Circulation leapt, and readers wrote in by the tens of thousands to confirm it, describing their own encounters with the races below and the rays that reached them. Blavatsky’s lost continent, Bulwer-Lytton’s underground masters, Fort’s inexplicable data and Lovecraft’s buried horrors had fused into a single pulp mythology that a large part of the reading public took for fact. It reached its height in a special issue given over entirely to the Shaver Mystery, on newsstands in June 1947.
That was the same month Kenneth Arnold saw his flying discs. Within weeks, the country was full of flying saucers, and Ray Palmer, who had just spent two years teaching a mass audience that unseen intelligences were real and hidden and watching, was perfectly placed to explain the new visitors from above. He co-founded a magazine called Fate to chronicle them, and promoted flying saucers so tirelessly for the rest of his life that he has been called the man who invented them. He did not invent them. What he did was hand the emerging UFO age a ready-made mythology, one assembled out of a century of science fiction and the centuries of damned data beneath it.
Then the loop closed at the very top. In 1948, when the United States Air Force ran its first serious investigation into the objects Arnold had reported, its analysts reached for a precedent to show that such things had been seen for a hundred years, and even cited the extravagant books of Charles Fort. The archive of the damned had travelled from a recluse’s shoeboxes, through the pulps, and into a classified national-security file, in the space of a single lifetime.
What the lineage does and does not mean
It would be easy to overreach here, and the honest version asks for restraint. Science fiction did not create the UFO phenomenon, and the phenomenon did not simply crawl out of the pulps. People have reported strange objects and buried worlds and visitors from the sky for as long as there are records to hold them, which was Fort’s whole point. What the lineage shows is a channel rather than a cause: one current of human attention, running from Lucian’s Moon to Kepler’s dream to Shelley’s monster to Fort’s shoeboxes to Shaver’s caverns to Arnold’s discs, carrying the same cargo the entire way. The things official knowledge could not or would not hold did not disappear when science shut the door on them. They went into stories, and the stories kept them alive.
That is why science fiction matters to anyone drawn to the edges of the known. It was one of the few places the excluded material was allowed to survive, imagined and re-imagined until the culture was ready to look at it head-on again. Kepler mixed astronomy with a summoning and nearly lost his mother to the stake. Shelley reached for a monster in a room full of poets. Gernsback’s magazine of scientific optimism became the launchpad of a lost-continent cult. At every step, the line between science and the forbidden that we are taught to treat as solid turns out to be something people cross constantly, usually without noticing they have done it.
Charles Fort spent his life insisting that the most honest posture towards a strange fact is to keep it on the table and refuse to look away. Science fiction, at its origins, was the imagination doing the same work, keeping room for everything reason had categorised as impossible too early. The genre we think of as the literature of the future has always been, in equal measure, the keeper of what the past forgot. And every so often, as in the summer of 1947, the things it was keeping walk back out into the daylight and ask to be taken seriously all over again.

If the strange facts that science files away never really vanish, and instead slip into our stories to wait, what might be sitting in today’s fiction right now, unrecognised, until the culture is ready to see it? And when you look at the flying saucers of 1947 or the disclosures of our own moment, do you see something genuinely new, or the same buried current surfacing once again?
