Martha (or Marthe) Brossier (1556 – after 1600) was a French woman, known for claiming demonic possession at the age of 22.
[B 1] According to Augustin Calmet, Martha was the daughter of a weaver in Romorantin who claimed to have been demonically possessed, drawing considerable notoriety.
[A 1] The maladies from which she was said to suffer included extreme shortness of breath, an ability to stick out her tongue unreasonably far, and the gnashing of her teeth.
She would writhe and move her mouth as if she had convulsions, while contorting her face, rolling her eyes, and appearing to show deep vexation and torment.
The Parlement of Paris nominated eleven physicians who all unanimously reported that there was nothing demonic in the matter,[A 2] suggesting that she used the physical strength of her stomach and breast to speak with her mouth shut.
