Is the Pope lunatic?
Pope Formosus was put on trial by a successor* Pope Stephen VII, even though he'd been dead for 9 months. Formosus' rotting corpse was dug up, plonked on a chair in the court and provided with a lawyer. Pope Steve then proceeded to rant and rave at the musty defendant who, taking his lawyer's advice, kept well shtum. The corpse was eventually found guilty where-upon it was stripped of its clothes, had assorted fingers chopped off and was chucked over a balcony to an angry mob (Is there any other kind?) who tossed it into the Tiber.
Stephen was later strangled to death.
