Feu follet (foo fow-lay) is a French phrase which translates to “marsh fire” or “crazy fire,” depending on who you talk to.
The phrase comes from the Acadians who were exiled by British command in the mid-1700s. Having Catholic heritage, thousands of Acadian families were ordered to leave their homes in North American British colonies because they refused to take on new Protestant influences. The exiled Acadians migrated to several different places, but one group of about two hundred of them eventually settled in Louisiana, declaring it their newfound home. These thriving families eventually became known as Cajuns.
Many Cajuns today say that their grandparents and ancestors before them used to tell stories that on the darkest of nights, you could see mysterious glowing orbs looming over the Louisiana horizon. Witnesses of this phenomenon called these orbs “swamp fairies,” or the “feu follet.”
Feu follet is described as bright or flickering balls of light randomly dancing in the dark shadows of the bayou. They’ve supposedly been seen in different sizes, but the average size is said to be no larger than a candle flame.
The mystery of this phenomenon became greater, and eventually led to the requirement of some sort of explanation.

Ignis Fatuus: The Mysterious and Enigmatic Lights of Folklore
Ignis fatuus, also known as “foolish fire,” refers to a wide variety of spectral lights that have captivated and frightened people across the world for centuries. These mysterious lights are often seen as omens of death or as mischievous entities that lead travelers astray. The term “ignis fatuus” itself stems from Latin, meaning “foolish fire,” a name derived from the belief that those who follow these lights are acting foolishly.
Appearance and Characteristics
Ignis fatuus lights typically manifest as bluish flames, ethereal blue or yellow globes, or candle-like lights that float and bob through the countryside at night. Their sudden and unexplained appearances have been reported in various regions around the world, making them a universal element of folklore. Whether seen as a single flickering light or as multiple lights dancing across marshlands, these eerie illuminations often evoke a sense of unease and wonder.
Death Omens and Travelers’ Mischief
In many cultures, ignis fatuus lights are seen as omens of death. They are known by various names, such as Corpse Candles, Dead Candles, and Will-o’-the-Wisps. These lights are believed to herald impending death, often appearing near graveyards or places associated with the dead. In some legends, they are thought to be the spirits of the deceased, lingering in the mortal world to warn the living of death’s approach.
On the other hand, ignis fatuus lights are also notorious for playing tricks on travelers. Often called Jack-o’-Lanterns, Jenny-burnt-tails, or Kit-in-the-candlesticks, these lights are said to lure unwary wanderers off their paths, leading them deeper into the wilderness until they become hopelessly lost. Such mischievous behavior has made ignis fatuus a symbol of treachery and deception in many folktales.
Legends and Interpretations from Around the World
The mysterious nature of ignis fatuus has given rise to numerous legends and interpretations. In one popular legend, the light is said to be the restless spirit of a sinner, doomed to wander the earth eternally, unable to find peace. This belief is particularly strong in the Lincolnshire fen country of Britain, where the lights, known as Will-o’-the-Wykes, are considered malevolent spirits.
In German folklore, the ignis fatuus is referred to as the Irrlicht, a ghostly light that is either a forest spirit or the soul of a departed person accompanying an invisible funeral procession. The appearance of such a light is often viewed with a mixture of fear and reverence, as it is seen as a direct connection to the spirit world.
In Sweden, the ignis fatuus is believed to be the soul of an unbaptized child. According to this lore, the child’s spirit tries to guide travelers to water in hopes of receiving a symbolic baptism, thereby finding peace. The light is seen as both tragic and redemptive, as the child’s spirit seeks salvation through this act.
Native American legends also feature ignis fatuus, with the Penobscot tribe calling it the “fire creature” or “fire demon.” This death omen spirit is said to spin its lighted fingertips in a wheel, skimming the milk at dairies during the night, adding a unique twist to the phenomenon. In parts of Africa, these lights are known as “witchfire,” believed to be either witches flying through the air or lights sent by witches to scare or punish wrongdoers.
Yes, I do like to trace things back to much earlier origins. 🙃
