Euethius

Holy Martyr Euethius is one of the twenty-⁠three martyrs commemorated on 26 August (new style) who died by the sword at Nicomedia in the fourth century, together with Saint Adrian. Their names are: Anatolius, Anthimus, Antiochus, Gentilius, Eleutherius, Hermogenes, Euethius, Euretus, Eutychius, Theagones, Theodore, Thyrsus, John, Carterius, Claudius, Cyriacus, Marinus, Mardonius, Menodius, Plato, Synetus, Troadius and Pharetrius.

The synaxarion relates that Adrian, of Nicomedia, a young man of twenty-⁠eight, married to Natalia, saw these Christians ready to die for the faith, was seized by what he heard, and declared to the pagans that he too was a Christian. He was imprisoned, Natalia came to strengthen him, and he died after torments. About Euethius no particulars of his own are preserved in the sources consulted.
