The Devils Bath -
The most striking feature of the Devil’s Bath is its color. The water ranges from a bright, acid yellow to a deep chartreuse, often glowing eerily against the surrounding grey rock and green ferns.
For decades, the color was a subject of curiosity and myth, leading to its ominous name. However, the color is not caused by sulphur, as many assume, nor is it chemical pollution.
The yellow tint is actually caused by suspended colloidal sulphur particles, but the specific hue is the result of a complex biological and chemical interaction:
The water level and shade of yellow fluctuate depending on rainfall and the amount of steam rising from the hydrothermal system beneath the crater.
The film’s power lies in its historical accuracy. Franz and Fiala based the script on court records of 18th-century Austria, where a phenomenon known as "Besessenheitsmord" (obsession murder) or suicide-by-execution occurred. Women, trapped in clinical depression with no vocabulary for mental health, would kill a child (often their own) specifically to be executed. In their logic, a beheading by a merciful executioner was kinder than an eternity of hellfire for self-harm.
This historical phenomenon is the subject of the 2024 Austrian historical horror film "The Devil’s Bath" (Des Teufels Bad) by directors Veronika Franz and Severin Fiala (the team behind Goodnight Mommy).
The film follows Agnes, a devout young woman in 18th-century Austria, whose marriage crushes her soul. She experiences the crushing apathy, sensory overload, and desperation of postpartum depression. In a society that views sadness as laziness or demonic possession, she sees only one way out: a path that leads to the executioner’s sword. the devils bath
The film avoids jump-scares for a slow, suffocating dread—immersing the viewer in the titular devil’s bath. It argues that the true horror is not supernatural evil, but a society that offers no help, no escape, and no language for the clinical hell of the mind.

This write-up covers the 2024 film The Devil’s Bath (Des Teufels Bad), a haunting period psychodrama directed by Veronika Franz and Severin Fiala. Overview
The Devil’s Bath is a bleak, atmospheric horror film set in 1750 rural Austria. It explores the devastating intersection of religion, mental illness, and gender expectations through a historical phenomenon known as "suicide by proxy". The title itself is a 17th-century term for depression, often referred to at the time as "the melancholy disease". Plot Summary
The Struggle of Agnes: The story follows Agnes (Anja Plaschg), a sensitive young woman who marries a farmer named Wolf (David Scheid). Despite her hopes for a happy life and motherhood, she finds herself trapped in a cold, loveless marriage and a demanding life of grueling labor.

A Spiraling Mind: Isolated and constantly criticized by her mother-in-law, Agnes falls into a deep, religious-fueled depression.
The Theological Loophole: In this society, suicide is a mortal sin that leads to eternal damnation. To escape her misery while still securing salvation, Agnes discovers a terrifying "loophole": committing a capital crime (such as murder) and then confessing before her execution to ensure she dies in a state of grace. Historical Context
True Accounts: The filmmakers drew heavily from the research of historian Kathy Stuart, who documented hundreds of cases of ritualistic child killings in Central Europe and Scandinavia during the 17th and 18th centuries.
Suicide by Proxy: This practice involved depressed individuals—primarily women—murdering innocent children (who were believed to be guaranteed a place in heaven) so they themselves could be executed after confessing. Critical Themes & Style

True to its name, this geothermal pool looks like a basin of toxic lime-green liquid. The vibrant, otherworldly hue is not dye or pollution; it is a result of high concentrations of arsenic and sulfur. As groundwater seeps deep into the earth, it is superheated by volcanic magma. The water dissolves minerals like arsenic, antimony, and mercury from the surrounding rocks before rising back to the surface. The water level and shade of yellow fluctuate
When the boiling water hits the air, hydrogen sulfide gas escapes, leaving behind a colloidal suspension of elemental sulfur. The arsenic rich water reflects light in a way that produces an unnatural, opalescent green. Early European settlers, seeing this steaming, foul-smelling cauldron surrounded by dead vegetation, believed it could only be a place where the Devil himself would bathe.
In the 21st century, we have specific clinical terms for depression: Anhedonia, MDD, Serotonin deficiency. Yet, the power of the phrase "The Devil’s Bath" lies in its visceral, tangible dread. A doctor’s diagnosis of "major depression" feels sterile. Telling someone you are "taking a bath with the devil" communicates the heat, the sulfur stench, and the drowning sensation of mental illness.
As we watch tourism videos of the glowing green pool in New Zealand, or sit in a dark theater watching Agnes drown in her own skin, we are reminded of three truths:
For the occult historians and alchemists, The Devil’s Bath holds a third meaning: a symbol of dissolution. In alchemical texts, the "Bath of the Devil" (or Balneum Diaboli) was a stage where base materials were corroded away to reveal the philosopher’s stone.
While less common today, this esoteric usage frames the devil’s bath as a necessary evil. Just as the acid pool in New Zealand destroys organic matter, the alchemical "bath" destroys the ego, the sin, or the "impure self" to leave behind a harder, more refined spirit.
