Thomas Potts preserves the official proceedings of the Lancashire assizes held at Lancaster Castle in August sixteen hundred and twelve, presenting an exhaustive account of the judicial inquiry into the witch mania that gripped the north of England. The narrative begins with the exposure of two elderly women, Elizabeth Southernes, known as old Demdike, and Anne Whittle, called old Chattox, who lived in the forest of Pendle and were accused of practicing witchcraft for decades. Their initial confessions opened a Pandora's box of mutual accusations, implicating their children, neighbors, and eventually individuals of higher social standing, such as Alice Nutter. The account details how these wretched individuals, living in deep poverty and isolation, internalized the suspicions of their neighbors and confessed to fantastic crimes under the pressure of magistrates and interrogators.
Potts chronicles the sensational discovery of a secret gathering at Malking Tower on Good Friday, where the accused allegedly plotted to murder the gaoler, blow up Lancaster Castle, and cast fatal spells on local gentry. The narrative proceeds through the harrowing arraignments and trials overseen by judges James Altham and Edward Bromley, highlighting the heavy reliance on spectral evidence and testimony extracted from young children, most notably nine-year-old Jennet Device, whose chilling testimony sealed the fate of her own mother, brother, and grandmother. A curious episode involving the Salmesbury witches introduces a darker conspiracy orchestrated by a seminary priest, who coached a young girl to fabricate accusations of cannibalism and demonic abuse against women who had converted to the established church. This particular fabrication collapses under judicial scrutiny, providing a stark contrast to the tragic outcome of the Pendle trials. Potts concludes with the formal sentencing and execution of ten individuals, preserving the exact language of the examinations, the formal indictments, and the moralizing exhortations of the judges, thereby creating an enduring historical monument to the judicial blindness and human cruelty of the early modern era.
