Roman officer in the army of Aurelius. Received Saint Julia of Troyes as a slave and a spoil of war. She pleaded with him not to rape her, offered to serve him otherwise, and promised to pray for him daily; he was moved to spare her, eventually treating her more as a daughter, and was finally converted by her. When Julia was martyred in the persecutions of Aurelian, Claudius made a public profession of his own faith. Martyr.
