The late 9th and early 10th centuries
were tough times for the Papacy. The
office was a tool in the Machiavellian arsenals of various political leaders,
and the so-called “Pornocracy” saw . . . wait, this is getting us away from the
point here: corpse on trial!
In 891, the Holy See was entrusted to one Formosus. The fact that his name means “Good-Looking”
puts him on my very select list of Awesomely-Named Popes, along with Sixtus V
and Lando. Formosus’ papacy isn’t as
interesting as his post-papal career, which coincided with his post-being alive
career. Stephen VI, who took the job
after a brief reign by a non-entity named Boniface, thought some things needed
to be set straight, specifically the fact that Formosus was bishop of Portus at
the time of his election, which should have disqualified him from another
bishop job. I quote Caesar Baronius
quoting Luitprand of Cremona (the translation is mine and terrible):
With this decided, [Stephen], so impious and
so ignorant of holy doctrine, decided to drag Formosus from his tomb and to set
him up on the Papal seat dressed in his priestly vestments. And to him he said: ‘When you were Bishop of
Portus, why did you with ambitions spirit usurp the universal Roman See?’ This
done, [Formosus] was straightway stripped of his sacred vestments, and three
fingers, with which it was his custom to bless, were cut off. They threw him headlong into the Tiber, and
all those whom he ordained were relegated to their previous positions.

The world had to wait until 1870 for a heavy metal album cover-worthy depiction of the Cadaver Synod, when Jean-Paul Laurens obliged.
Formosus’ defense is not recorded here, although
it is said in other sources that when Stephen asked his question, a young
cleric kneeling behind Formosus’ seat responded, “because I was evil.” That’s the kind of thing that would get a
conviction overturned on appeal these days, and that’s more or less what
happened with Formosus. A monk fished
his body out of the Tiber, and he was buried again in St. Peter’s. At some point the church decided that
Formosus was OK, and now Stephen’s the bad guy. Which just goes to show you.
