martyrs of Rome. Buried in the cemetery of Commodilla on the Ostian Way, they must be among the most solidly attested of all Roman martyrs, with feasts in the early Roman Sacramentaries, inscriptions from the pontificates of Siricius and Damasus, and a church built over their tomb, uncovered in 1905. Felix, a Roman priest, suffered in the beginning of Diocletian's persecution. On his way to execution he was joined by a stranger, who also confessed that he was a Christian and suffered with Felix. As his name was not known he was called Adauctus (= the one added). Feast: 30 August.
