Sasha Volokh, who has an amazing sense of humor and history, points out a Rashomon effect from 1378:
[I]n 1378, the cardinals were electing a new Pope, and the people of Rome were putting substantial pressure on the cardinals to elect a Roman pope. During this process, Cardinal Orsini went out to talk to the crowd. Here’s how the Bishop of Todi remembers what Orsini said:
Listen to me, Romans, if you should not have a pope who proves acceptable to you by this evening I will allow you to tear me to pieces.
Here’s how the Bishop of Marseilles remembers it:
You Roman pigs, get away from here with your impudent demands. When I get out I will chase you with my stick.
