When the capital of the Roman Empire was in the grip of a violent earthquake, it fell to one small child to save all the people.
According to tradition, the Trisagion or Thrice-Holy Hymn was revealed by angels one September 24th during the tenure of Patriarch Proclus of Constantinople (434-446). Some thirty years later Peter, the abrasive Patriarch of Antioch and a former fuller by trade, took it upon himself to add an extra line. Three centuries after that John Damascene was still upset about it.
