Historical Context
Anazarbus, where Marinus is placed, was an ancient city of Cilicia in Asia Minor, near the modern Turkish town of Anavarza. Under the late Roman Empire it served as the capital of Cilicia Secunda and later became a significant ecclesiastical center and metropolitan see. Its proximity to Tarsus — the seat of the provincial governor — frames the account of Marinus's martyrdom, since his execution was ordered by Lysias, the governor of Tarsus.
Marinus suffered during the Diocletianic Persecution, the most severe and systematic persecution of Christians in the Roman Empire. Beginning in 303, a series of edicts stripped Christians of legal rights, ordered the arrest of clergy, and ultimately required all persons to sacrifice publicly to the pagan gods or face execution. Cilicia lay within the eastern sphere governed directly by Diocletian, where enforcement was severe and regional governors held authority to arrest, torture, and execute Christians who refused to apostatize. A Christian elder who openly confessed the faith and declined to sacrifice could be put to death by the local governor's order, as the account of Marinus reflects.
