During the persecution of Diocletian and Maximian, about the year 290, Saints Onesiphorus and Porphyrius were betrayed as Christians to the persecutors. After many torments through which they stood fast in confessing their faith, they were bound by the feet to wild horses and dragged to death.

Apolytikion in the Fourth Tone

Thy Martyrs, O Lord, in their courageous contest for Thee received as the prize the crowns of incorruption and life from Thee, our immortal God. For since they possessed Thy strength, they cast down the tyrants and wholly destroyed the demons' strengthless presumption. O Christ God, by their prayers, save our souls, since Thou art merciful.

Kontakion in the Second Tone
