A Diabolical Pact

Here, courtesy of Wikipedia, is a page written in backwards Latin, supposedly codifying the agreement between Catholic Priest Urbain Grandier and a whole bunch of Demons, including Lucifer, Satan, Astaroth, and a few others.  Apparently, in exchange for his soul, Grandier would become completely irresistible to women, would have the friendship of the rich and powerful, and would himself receive more than his fair share of worldly power and pleasure.  This document was used as evidence for Grandier's diabolical powers in his trial, eventually sending him to be burned at the stake.
