In the 8th Century an exorcism was performed on a 16 year old girl.  The girl began to speak in Latin, which she did not know, claiming to be a demon named Wiggo.  The demon claimed to have been roaming the countryside doing terrible things because the lack of piousness and Christian behavior of the people and their leaders allowed his presence.  Was this a case of demonic possession or a cover for the priest and chronicler to publish a critique of the powers that be under cover of claiming it was spoken by a demon.  Take a listen and see what you think.
