The Devils — Bath

If you are a historian or a linguist, The Devil’s Bath has a much darker, metaphorical meaning. In pre-industrial Europe, specifically in Germany and Austria (known as des Teufels Bad), the phrase was a colloquialism for a severe, debilitating state of depression—what we would today call Major Depressive Disorder or acedia.

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.

These women believed that by committing a capital crime, confessing, and receiving last rites, they could bypass Purgatory and Hell entirely—since execution was seen as an act of atonement. The title refers to the folk belief that the devil’s bath (a stagnant, soul-sapping swamp) is where such desperate thoughts fester.
