Artemius was a 4th-century Syrian general and the imperial prefect of Roman Egypt. Serving under the Emperor Constantius II, he held the rank of dux Aegypti and was reportedly tasked with recovering various apostolic relics. Following the rise of the Emperor Julian, who returned to paganism, Artemius faced execution. Although historical accounts regarding his specific actions and the exact location of his death vary, he is remembered for refusing to renounce his Christian faith during torture, leading to his martyrdom in Antioch.
Life and service

As a high-ranking military official, Artemius supported the Arian bishop George the Cappadocian during his administration in Egypt. Some traditions suggest he earned his prestigious position by retrieving the remains of Apostles such as Andrew and Luke for the Emperor. His political influence and military status made him a notable figure in the late Roman Empire before his eventual confrontation with the pagan Emperor Julian.
Martyrdom and veneration
Artemius is honored as a great martyr in Catholic, Eastern Orthodox, and Oriental Orthodox traditions. He is commemorated on October 20. According to hagiographical accounts, he was executed by Julian after defending Christian priests against imperial persecution. In religious tradition, he is often invoked for healing, particularly regarding medical issues such as hernias.
