Some monsters have been haunting human stories for thousands of years. Others arrived surprisingly recently, helped along by newspaper headlines, blurry photographs, mistranslations, and the occasional hippopotamus-foot ashtray. In many cases, even cryptids that may seem to have an ancient lineage — such as Bigfoot and the Yeti — acquired their familiar names and appearances only in the past century or so.

From glowing-red-eyed winged beings to ship-crushing sea creatures, these famous beasts developed in very different ways. Some may have been inspired by real animals or fossils; others can be traced to a particular sighting, publicity stunt, or hoax. Here’s a look at the origins of seven of the most famous mythical monsters.

Bigfoot, aka Sasquatch

Stories of giant, hairy “wild men” living on the edges of civilization appear in cultures around the world, but the names Sasquatch and Bigfoot have much more specific histories. In the 1920s, teacher John W. Burns collected accounts of wild man figures while working on the Chehalis Indian Reservation in British Columbia’s Fraser Valley. He anglicized the term sæsq’ec, which comes from Halkomelem (a Coast Salish language), as “Sasquatch,” and introduced it to a wider audience in a 1929 article in Maclean’s magazine. In 1957, the nearby resort town of Harrison Hot Springs proposed staging a Sasquatch hunt as part of British Columbia’s centennial celebrations; officials rejected the proposal, but the resulting publicity revived the nearly forgotten creature and sent the story around the world.

The familiar term “Bigfoot” emerged in Northern California in the summer of 1958. Loggers near Bluff Creek reported that an intruder was disturbing their equipment and leaving enormous footprints. After worker Jerry Crew posed with a plaster cast for the Humboldt Times, the “Big Foot” story became a national sensation. The tracks were later attributed to carved wooden feet reportedly used by construction worker Ray Wallace, but the name stuck — and eventually merged with the older Sasquatch tradition.
