Historical Context
By the third and fourth centuries Campania was a well-established Roman province closely tied to Rome, part of the Augustan administrative region of Latium et Campania, valued for its fertile countryside. Christianity had taken root there during the Roman period, and the region produced several martyrs, making it a center of early Christian activity and of persecution under Diocletian. Salerno, the ancient Salernum, was a prominent coastal city of the region.
The Diocletianic persecution, the last and most severe imperial campaign against the Church, mandated that all persons sacrifice to the pagan gods. In Italy it was enforced under the co-emperor Maximian until his abdication in 305, after which enforcement weakened. This is the setting in which Christian communities, including monastics, fled or disguised themselves, as the tradition records of Archelais, Thekla, and Susanna.
