A native of Egypt, the first duke of Emperor Constantine the Great. He saw the victorious cross, which he announced to the emperor, and was baptized. He brought the relics of Saint Andrew of Patras and Saint Luke of Thebes to Constantinople. When Julian the Apostate went against the Persians, he ordered Artemius, who was the imperial governor in Egypt, to come with an army to Antioch. There the emperor put the priests Eugenius and Macarius to torture, to which Saint Artemius objected and prophesied the emperor's imminent death. The enraged emperor threw the duke Artemius into torture. In prison, the Lord visited him and healed him. Then they laid him on a stone, pressed another, large stone, and completely flattened his body. Then they cut off his head. Saint Artemius suffered for the Lord in the year 363.

Saint Righteous Artemius. Venerable Gerasimus the New. Venerable New Martyr Ignatius.
