On this day in history, August 18, 1612... One of England's most famous witch trials began. Twelve people were accused of murdering ten people through the use of witchcraft. One of the key witnesses was nine-year-old Jennet Device. Because of her age, she would not have been permitted to testify in many other 17th-century criminal trials. However, King James had made a case for suspending the normal rules of evidence for witchcraft trials in his Daemonologie. Jennet gave evidence against her mother, brother, and sister.
