During the witch-trials in early modern Europe, individuals were employed to help aid in the discovery and conviction of witches. These individuals were given the title "witch finders". Perhaps the most famous witchfinder was a man named Matthew Hopkins (c. 1620–1647), who claimed to be the "Witch Finder General". Hopkins' writings reached the height of their popularity during the English Civil War (circa 1645), and contributed to the use of the witches' mark as evidence of guilt. The record shows that two Scottish women disguised themselves as men, known as "Mr. Dickson" and "Mr. Peterson", so they, too, could become witch-finders.
