virgin and martyr. A martyr of this name, buried in a Roman cemetery a little way from the church of St Agnes on the Via Nomentana, suffered probably with the martyrs Victor, Felix, and Alexander on 16 September. But her Legend, followed by the Roman Martyrology, makes her a foster-sister of Agnes, stoned to death while praying at her tomb. This connection ensured her popularity and may have determined the date of her feast on 23 January, two days after that of Agnes.
