Artemios the Great Martyr of Antioch

Reading from the Synaxarion:

Saint Artemius lived during the years of Saint Constantine the Great,
and was appointed by him to be Governor of Alexandria; later, he was
honoured with the rank of patrician. During the reign of Julian the
Apostate, in the year 361, Artemius appeared before the Emperor and
censured him for his apostasy. For this, he endured many torments and was
finally beheaded.

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

Kontakion in the Second Tone
Let us now gather and worthily acclaim with hymns the pious and
crowned Martyr Artemius, the greatest among Martyrs and richest bestower
of miracles, who raised the trophies of victory over the enemy; for
he intercedeth with the Lord for us all.
