The Heat of the Matter: A Trial by Fire Meaning Defined

Trial By Fire Idiom Meaning Origin

The Origin and Etymology of Trial by Fire

A trial by fire usage trend.

The expression a trial by fire originated from medieval practices known as the ordeal by fire. These were forms of trial where innocence or guilt was determined by forcing dangerous, often horribly painful tasks onto the accused, like walking over hot coals, sometimes while holding a heated iron. The crazy belief was that divine intervention would protect the innocent if they were actually innocent.

This practice was made even more popular around the world during the Salem Witch Trials, where women accused of being witches would be tied to a post and a fire set aflame at their feet. If they were a witch, they’d burn. If they weren’t a witch, they’d be saved from the lick of flames.

There was also a trial by water used similarly, where they’d tie up the woman accused and toss her in the water. The belief was that a witch would float, and an innocent woman would sink. They’d yank her up by the rope if she sank, but sometimes, no matter the outcome, the woman would drown.
