 In 875 Bishop Rainaldus was summoned to appear before the papal apocrisiarius Gregory and the magister militum Georgius, the vestiarius of the Patriarch of Aquileia, to answer a charge of homicide.Having failed to deal with the situation, despite several letters of excommunication, Rainaldus was summoned by Pope John VIII to appear in Rome and stand trial.Rainaldus appeared at the papal court, but stealthily avoided taking his seat in the synod, and instead fled the city by going over the walls like a thief.
