Historical Context
The deaths of Tigrius and Eutropius belong to the violent aftermath of the second exile of John Chrysostom, archbishop of Constantinople, who had been condemned by the Synod of the Oak and removed from his see. His many supporters in the capital — the so-called Johannites — were treated as enemies of the new ecclesiastical order, and several suffered imprisonment, torture, or banishment for refusing communion with his successors.
The synaxarion accounts identify both men as clergy under Chrysostom: Tigrius a presbyter and Eutropius a reader. The charge of arson, brought after a fire damaged buildings in the city, served as a legal pretext for moving against Chrysostom's circle. By tradition the civil prefect who pressed the prosecution is named Optatus and described as a pagan.
