The Holy Martyr Eustathios was a soldier. For confessing the Christian faith he was arrested and brought before the head of the city on Ancyra. At the interrogation, the saint firmly and bravely confessed himself a Christian and was sentenced to tortures. They beat him without mercy, they bore into the heels and, having tied him about with rope, they dragged him in the city to the River Sagka (Sangara). At the bank of the river they put the martyr into a wooden chest and threw it in the water. An Angel of God brought the chest to shore. The saint, situated in the chest, was singing the 90th (91st) Psalm: "He that dwelleth in the help of the Most-High..." Beholding the miracle and sensing himself disgraced, the governor having drawn his sword killed himself. The holy martyr, having received Communion from the hand of an Angel, gave up his spirit to God (+ c. 316). His venerable relics were buried in the city of Ancyra.
