Commemorates the attempted martyrdom of Saint John the Apostle in 95. John was bound and brought to Rome, Italy from Ephesus by the order of Domitian; the Senate condemned him to be taken to the Latin Gate and thrown in a cauldron of boiling oil. John stepped out of the cauldron without injury, and instead was exiled to Patmos.
