Isaurus the Holy Martyr & his Companions of Athens
The holy Martyr Isaurus, a deacon, and Basil and Innocent were from Athens. In the reign of Numerian (283-284), they came to Apollonia (most likely, the city in Illyricum); there encountering Felix, Peregrinus, and Hermias hidden in a cave, they strengthened them in their Faith. Betrayed to Tripontius the Proconsul, all but Isaurus and Innocent were beheaded; these last two Tripontius gave over to his son, Apollonius, who tormented them, and then had them beheaded.
Apolytikion of Martyr Isaurus & Companions 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.
