Eusebius of Caesarea, Martyrs of Palestine, 7.1-2

Summary:
On 2 April 308, the young woman Theodosia, who led a life of virginity in the city of Tyre, approached and publicly greeted the imprisoned Christians while they were sitting in the governor's court. She was at once arrested and brought before Urbanus, the governor of Caesarea. After Theodosia refused to offer sacrifice to the pagan gods, she was severely tortured. When the governor saw that the tortures could not break the martyr's spirit, he ordered her to be executed by being cast alive into the sea. Following that, Urbanus mitigated the punishment for those Christian confessors, on whose behalf Theodosia had suffered, by sending them to the copper mines in Palestine.
