Her father Gabinus was arrested and starved to death in prison. Maximus and Claudius, together with Claudius’s wife Prepedigna and their children, Alexander and Cuzia are all martyred. Ironically the only survivor was Pope Caius, who had escaped and hid in the catacombs. These murders within Diocletian’s own family would foreshadow the last great persecution against the Christian church which the Emperor began in 303 AD. Diocletian’s daughter Valeria was divorced, and in June 293 AD married Maxentius who would succeed Diocletian in 305 AD.
In the year 330 AD, a basilica was built over the site of the house of Susanna. It was first named San Caius in honor of the pope who had lived here. The bodies of Susanna and Gabinus were brought back from the catacombs and buried in the church.
