The Use of Evidence in Early Modern Witch Trials

The evidentiary standards used in witch trials during the early modern period (roughly 1450-1750) were unlike anything in modern jurisprudence. Courts accepted 'spectral evidence' — testimony that the accused's spectral form appeared to the witness in dreams or visions. They employed 'swimming tests,' in which accused witches were bound and thrown into water; those who floated were guilty (rejected by the 'pure' water), while those who sank were innocent (but often drowned). Physical examinations searched for the 'Devil's mark' — any unusual blemish, mole, or insensitive spot on the body was taken as proof of a demonic pact. Confessions obtained through torture were considered the gold standard of evidence, and the methods employed were devastating: strappado, thumbscrews, sleep deprivation lasting days, and the rack. Under such duress, accused individuals would confess to anything and name additional 'witches,' creating cascading accusations that could consume entire communities. The legal frameworks varied by country — the Constitutio Criminalis Carolina (1532) in the Holy Roman Empire codified torture procedures, while English common law was somewhat more restrained, though no less deadly in its outcomes.
