Satan and the Sicilian Nun

In 1676, a Sicilian nun claimed she was battling Satan, and in the process produced a letter that was not deciphered until 300 years later.

“She confessed that she was possessed by Lucifer to the priest when she felt an intense fit of rage. She targeted her anger towards the priest. After coming to her senses, Sister Maria showed no signs of being aware of what she had done.”

Sister Maria’s letter dictated by Satan according to her.
Sister Maria’s life after the letter remains unknown
