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.
