Smithsonian Magazine has a fascinating story about a Russian family who were isolated in the taiga for 40 years before being discovered by a surveying crew in the summer of 1978.
The sight that greeted the geologists as they entered the cabin was like something from the middle ages. Jerry-built from whatever materials came to hand, the dwelling was not much more than a burrow—”a low, soot-blackened log kennel that was as cold as a cellar,” with a floor consisting of potato peel and pine-nut shells. Looking around in the dim light, the visitors saw that it consisted of a single room. It was cramped, musty and indescribably filthy, propped up by sagging joists—and, astonishingly, home to a family of five:
“The silence was suddenly broken by sobs and lamentations. Only then did we see the silhouettes of two women. One was in hysterics, praying: ‘This is for our sins, our sins.’ The other, keeping behind a post… sank slowly to the floor. The light from the little window fell on her wide, terrified eyes, and we realized we had to get out of there as quickly as possible.”
Led by Pismenskaya, the scientists backed hurriedly out of the hut and retreated to a spot a few yards away, where they took out some provisions and began to eat. After about half an hour, the door of the cabin creaked open, and the old man and his two daughters emerged—no longer hysterical and, though still obviously frightened, “frankly curious.” Warily, the three strange figures approached and sat down with their visitors, rejecting everything that they were offered—jam, tea, bread—with a muttered, “We are not allowed that!” When Pismenskaya asked, “Have you ever eaten bread?” the old man answered: “I have. But they have not. They have never seen it.” At least he was intelligible. The daughters spoke a language distorted by a lifetime of isolation. “When the sisters talked to each other, it sounded like a slow, blurred cooing.”
Slowly, over several visits, the full story of the family emerged. The old man’s name was Karp Lykov, and he was an Old Believer—a member of a fundamentalist Russian Orthodox sect, worshiping in a style unchanged since the 17th century. Old Believers had been persecuted since the days of Peter the Great, and Lykov talked about it as though it had happened only yesterday; for him, Peter was a personal enemy and “the anti-Christ in human form”—a point he insisted had been amply proved by Tsar’s campaign to modernize Russia by forcibly “chopping off the beards of Christians.” But these centuries-old hatreds were conflated with more recent grievances; Karp was prone to complain in the same breath about a merchant who had refused to make a gift of 26 poods [940 pounds] of potatoes to the Old Believers sometime around 1900.
