The Holy Martyrs Theodore, Mianus (Ammianus), Julian and Kion (Oceanus) lived during the reign of Maximian (284-305)and were from the village of Quandababa (near Nicomedia). For confessing faith in Christ they were arrested and given over to torture.
At first their bodies were torn with sharp iron hooks, and then they were locked into a hot and flooded bath-house. The doors were locked and sealed with the imperial signet ring so that they should not escape. An angel of the Lord freed them, however.
Soldiers arrested the martyrs again and led them outside the city for execution. The saints at their request were given time for prayer, and then they surrendered their souls to the Lord. Their bodies were hacked into pieces and thrown into a fire.
