In 1697, seven people were condemned at Paisley for using witchcraft to torment Christian Shaw, daughter of the laird of Bargarran. For seven months, Christian had bizarre seizures during which she claimed to see the Devil and her tormentors assaulting her. She also exhibited pica and said that the foreign material had been forced into her mouth by her invisible assailants. The notable Glasgow physician, Matthew Brisbane, was consulted and gave evidence at the trial; he could find no natural explanation for the pica. It is likely that Christian had a dissociative (conversion) disorder after being cursed by a servant. Christian recovered and later married the minister of Kilmaurs. After his untimely death, she established a highly successful spinning business which lead to the Paisley cotton industry.
