In 897 A.D., Catholic Pope Stephen (VII) put former Pope Formosus on trial - despite Formosus having been dead for nine months.  Pope Stephen was so enraged over Formosus' actions 30 years prior that he had his body exhumed, clad him in papal robes and propped him on a throne at the Basilica of St. John Lateran in Rome, complete with a deacon for legal council.  The reasons for his rage stemmed from a complicated political power struggle.  (If you want more details just google Cadaver Synod or Cadaver Trial.)  Pope Stephen, as lead prosecutor, shouted his arguments at the corpse.  The final verdict was, of course, guilty.  Formosus was stripped of his sacred vestments, had 3 fingers cut off his right hand (the one used for blessings), had all his ordinations annulled and was eventually thrown into the Tiber River.  A local monk reportedly drug his body out of the water days later and reinterred him at St. Peter's Basilica.  It's reported that another Pope exhumed him again in 904 A.D., beheaded him and again threw his body in the Tiber.  In case you're wondering, the Catholic Church has since banned any future physical prosecutions of corpses (round of applause!) and Pope Formosus and his acts were posthumously reinstated.  Most metal phrase of the day: DAMNATIO MEMORIAE: Meaning condemnation of memory, everything you ever did wiped from the books.
