Roman Martyr in Egypt, 363-363, under Julian. According to his Acts, which are not very reliable, he was a distinguished general in the war against the Persians, was consul with Symmachus, 333 (perhaps also once before with Bassus, 317). After his conversion to Christianity he retired to Ostia, founded a hospital and endowed a church built by Constantine. Under Julian he was banished to Egypt, and lived with the hermits in the desert. A small church was built in his honour in the Trastevere of Rome. His relics are at Rome in the church of Sant’ Andrea della Valle. The legend of his conversion was dramatized by Roswitha.
