Martyrdom at Chios
The accounts agree that the men were betrayed after their ship was stranded near Tsesme and that they were imprisoned in the castle of Chios. Foreseeing their death, the brothers are said to have told their fellow prisoners that the next day would be their last, and to have written out their confession of faith and sent it to the bishop of Chios, asking to receive the Holy Mysteries before they died.
Stamatios and John were beheaded beneath an old fountain at Vounaki. The synaxarion relates that, after their deaths, their bodies were cast into the sea, but were carried back to shore some days later, where the faithful recovered them and buried them secretly.
