*The poor guy's mind cracked in a French prison while he was awaiting the guillotine during the Terror, an experience that might well have unhinged the strongest.

The "Air Loom"[edit]
Matthews's illustration of the Air Loom.
Matthews believed that a gang of criminals and spies skilled in pneumatic chemistry had taken up residence at London Wall in Moorfields (close to Bethlem) and were tormenting him by means of rays emitted by a machine called the "Air Loom" or gaseous charge generator. The torments induced by the rays included "Lobster-cracking", during which the circulation of the blood was prevented by a magnetic field; "Stomach-skinning"; and "Apoplexy-working with the nutmeg grater" which involved the introduction of fluids into the skull. His persecutors bore such names as "the Middleman" (who operated the Air Loom), "the Glove Woman" and "Sir Archy" (who acted as "repeaters" or "active worriers" to enhance Matthews' torment or record the machine's activities) and their leader, a man called "Bill, or the King".
Matthews' delusions had a definite political slant: he claimed that the purpose of this gang was espionage, and that there were many other such gangs armed with Air Looms all over London, using "pneumatic practitioners" to "premagnetize" potential victims with "volatile magnetic fluid". According to Matthews, their chief targets (apart from himself) were leading government figures. By means of their "rays" they could influence ministers' thoughts and read their minds. Matthews declared that William Pitt was "not half" susceptible to these attacks[3] and held that these gangs were responsible for the British military disasters at Buenos Aires in 1807 and Walcheren in 1809 and also for the Nore Mutiny of 1797....
