Confession under Theophilos
The reign of the emperor Theophilos (829-842) marked the last sustained imperial effort to suppress the veneration of icons. The tradition records that Sergius and Irene were unusual among government families in their open devotion to the iconophile cause and to the venerable monks who defended the images.
When Sergius was brought before the emperor, he was subjected to public humiliation: by the account, a rope was tied around his neck and he was paraded through the marketplace of Constantinople to be mocked. He was afterward imprisoned and then sentenced to exile together with his wife and children. He bore the afflictions of banishment and died during this period, and his wife is held to have died at about the same time.
