How did you detect a witch?

In historical contexts, witch detection often involved various superstitious methods, such as the use of "witch tests." Common practices included the water test, where a suspect would be thrown into water; if they floated, they were deemed a witch, while sinking indicated innocence. Other methods included examining for "witch marks" on the body or conducting trials based on spectral evidence. However, these practices were largely based on fear and superstition rather than any scientific basis.
